Explanation
To automate infrastructure and configure Oracle Cloud Infrastructure (OCI) resources, the recom-mended tool to use is Ansible. Ansible is a popular automation tool that focuses on provisioning, configuring, and managing IT infrastructure. It uses a declarative language called YAML to de-scribe the desired state of the infrastructure, allowing you to define and automate the configuration of OCI resources such as Compute, Load Balancing, and Database services. Ansible provides a col-lection specifically designed for OCI, called the
"Ansible Collection," which includes modules and playbooks for interacting with OCI APIs. By utilizing Ansible in OCI, you can easily automate the provisioning and configuration of your infrastructure, ensuring consistency and reproducibility. An-sible's simplicity and agentless architecture make it a flexible and efficient choice for managing OCI resources and automating infrastructure tasks in the context of OCI DevOps.

You as a DevOps Engineer are asked to manage an application to be deployed in Oracle Cloud Infrastructure Container Engine for Kubernetes (OKE). This requires pulling images from Oracle Cloud Infrastructure Registry (OCIR) during deployment. Which three statements are true? (Choose three.)
- A. Add a containers section that specifies the name and location of the images you want to pull from OCIR.
along with other deployment details. - B. Add an imagePullSecrets section to the manifest file that specifies the name of the Docker secret you created to access OCIR
- C. Add an image section that specifies the name and location of the images you want to pull from OCIR along with other deployment details.
- D. Use kubectl to create a Docker registry secret.
- E. Add an Auth section to the manifest file that specifies the name of the Docker secret you create using Auth Token to access OCIR.
Answer: A,B,D
Explanation:
Explanation
The three statements that are true regarding managing an application deployed in Oracle Cloud Infrastructure Container Engine for Kubernetes (OKE) and pulling images from Oracle Cloud Infra-structure Registry (OCIR) are: Use kubectl to create a Docker registry secret: To access images from OCIR, you need to create a Docker registry secret in Kubernetes. This can be done using the ku-bectl create secret docker-registry command. Add a containers section that specifies the name and location of the images you want to pull from OCIR, along with other deployment details: In your deployment manifest (e.g., YAML file), you need to define a containers section that specifies the image names and locations from OCIR. This section includes other deployment details such as re-source limits and environment variables. Add an imagePullSecrets section to the manifest file that specifies the name of the Docker secret you created to access OCIR: To authenticate and pull images from OCIR, you need to specify the name of the Docker registry secret in the imagePullSecrets section of your manifest file. This ensures that the appropriate credentials are used to authenticate with OCIR and pull the required images. These steps enable your application deployed in OKE to pull the necessary container images from OCIR during deployment, ensuring smooth and secure deployment of your application. Reference:

NEW QUESTION # 64
A DevOps engineer is asked to access an Oracle Cloud Infrastructure Container Engine for Kubernetes (OKE) cluster to deploy new applications and manage existing ones. Which three statements are true? (Setting Up Cluster Access). (Choose three.)
- A. To access the cluster using kubectl you have to set up a Kubernetes manifest file for the cluster. The kubeconfig file by default is named config and stored in the $HOME/.manifest directory
- B. To access the cluster using kubectl you have to set up a Kubernetes configuration file for the cluster.
The kubeconfig file by default is named config and stored in the $HOME/.kube directory. - C. Generating an API signing key pair is a mandatory step while setting up cluster access using local machine if the public key is not already uploaded in the console.
- D. When a cluster's Kubernetes API endpoint has a public IP address, you can access the cluster in Cloud Shell by setting up a kubeconfig file
- E. You cannot setup Cloud shell access to the cluster if the clusters Kubernetes API end-point has a private IP address.
Answer: B,C,D
Explanation:
Explanation
The three statements that are true regarding setting up cluster access for an Oracle Cloud Infrastructure Container Engine for Kubernetes (OKE) cluster are: When a cluster's Kubernetes API endpoint has a public IP address, you can access the cluster in Cloud Shell by setting up a kubeconfig file. This allows you to authenticate and interact with the cluster using kubectl. Generating an API sign-ing key pair is a mandatory step when setting up cluster access using a local machine if the public key is not already uploaded in the console. This key pair is used for authentication and securing the connection to the cluster. To access the cluster using kubectl, you need to set up a Kubernetes con-figuration file (kubeconfig) for the cluster. By default, the kubeconfig file is named "config" and is stored in the $HOME/.kube directory. This file contains the necessary information and credentials to authenticate and communicate with the cluster. These steps enable the DevOps engineer to access and manage the OKE cluster, deploy new applications, and manage existing ones using kubectl or other Kubernetes management tools. Reference:

NEW QUESTION # 65
As a cloud engineer, you are responsible for managing a Kubernetes cluster on the Oracle Cloud Infrastructure (OCI) platform for your organization. You are looking for ways to ensure reliable operations of Kubernetes at scale while minimizing the operational overhead of managing the worker node infrastructure. Which cluster option is the best fit for your requirement?
- A. Creating and managing worker nodes using OCI compute instances.
- B. Using Kubernetes cluster add-ons to automate worker node management.
- C. Using OCI OKE virtual nodes to eliminate worker node infrastructure management.
- D. Using OCI OKE managed nodes with cluster autoscalers to eliminate worker node infrastructure management.
Answer: C
Explanation:
Explanation
The cluster option that is the best fit for ensuring reliable operations of Kubernetes at scale while minimizing the operational overhead of managing the worker node infrastructure is using OCI OKE virtual nodes to eliminate worker node infrastructure management. OKE is a fully managed service that allows you to run and manage your Kubernetes cluster on OCI. A Kubernetes cluster consists of a control plane and a set of worker nodes that run your containerized applications. OKE provides a highly available and secure control plane that is managed by Oracle, while you are responsible for managing the worker node infrastructure. However, OKE also supports virtual nodes, which are serverless compute resources that are automatically provisioned and scaled by OCI based on your application workload demands. Virtual nodes eliminate the need for managing worker node infrastructure, such as security patches, updates, scaling, etc. Virtual nodes also offer a serverless Kubernetes experience, where you can focus on developing and deploying your applications without worrying about the underlying infrastructure.

NEW QUESTION # 66
A company wants to automate the infrastructure and configure OCI resources on OCI DevOps. Which tool should the company use? (Choose the best answer.)
- A. Chef
- B. Ansible
- C. Jenkins
- D. Terraform
Answer: B
Explanation:
Explanation
The company should use Ansible to automate infrastructure and configure OCI resources on OCI DevOps.
Ansible is a popular open-source automation tool that provides a simple and powerful way to automate infrastructure provisioning, configuration management, and application deployments. It uses a declarative language and follows an agentless architecture, making it easy to use and suitable for automating tasks across different environments, including OCI. While Jenkins is a widely used continuous integration and continuous delivery (CI/CD) tool, it is primarily focused on the software development and deployment process rather than infrastructure automation and resource configuration. Terraform is another popular infrastructure-as-code tool that enables the provisioning and man-agement of infrastructure resources. It is well-suited for creating and managing infrastructure re-sources in OCI and other cloud providers. However, in the context of the question, Ansible is specifically mentioned as the tool to use. Chef is a configuration management tool that helps automate the configuration and management of systems and applications. It can be used for infrastructure automation and configuration, but it is not as commonly used for provisioning and managing cloud resources as Ansible or Terraform. Therefore, the best answer for the given scenario is Ansible.

To accomplish this, they are concentrating on incorporating DevSecOps best practices into their DevOps process. Which three are best practices that ABC Inc. should im-plement?
- A. Follow established security guidelines, such as the OWASP DevSecOps guideline, during the development and testing process.
- B. Have a flat network with no segmentation or isolation, where all devices and resources are interconnected and accessible to anyone on the network.
- C. Manually execute DevOps security processes and tools to reduce the risk of errors and security incidents.
- D. Perform regular scans for vulnerabilities and prioritize fixing them based on their se-verity
- E. Implement role-based access control and define roles and responsibilities for everyone involved in the development process.
Answer: A,D,E
Explanation:
Explanation
The best practices that ABC Inc. should implement to incorporate DevSecOps into their DevOps process are:
* Follow established security guidelines, such as the OWASP DevSecOps guideline, during the development and testing process. The OWASP DevSecOps guideline is a set of recommendations and tools that help developers and testers integrate security into every stage of the software development lifecycle (SDLC). The guideline covers topics such as threat modeling, secure coding, code analysis, security testing, vulnerability management, etc.
* Perform regular scans for vulnerabilities and prioritize fixing them based on their severity. Vulnerability scanning is a process of identifying and assessing the security risks in your code, dependencies, images, containers, or infrastructure. You can use tools such as SonarQube, Sonatype Nexus IQ Server, or
* Twistlock to perform vulnerability scanning and generate reports with detailed information and remediation suggestions. You should also prioritize fixing the vulnerabilities based on their severity level and potential impact.
* Implement role-based access control and define roles and responsibilities for everyone involved in the development process. Role-based access control (RBAC) is a method of restricting access to resources based on the roles of the users or groups. You can use RBAC to enforce the principle of least privilege, which means granting only the minimum level of access required for each user or group to perform their tasks. You should also define clear roles and responsibilities for everyone involved in the development process, such as developers, testers, operations staff, security staff, etc., and assign them appropriate permissions and policies.

NEW QUESTION # 68
You're using Oracle Cloud Infrastructure (OCI) DevOps to deploy your application on an Oracle Container Engine for Kubernetes (OKE) environment. You push your code to the OCI Code Repository, add a stage and configure the build pipeline. When you run the build, you see "unable to clone the repository" error. What could the configuration error be?
- A. More stages were added than required to the build pipeline.
- B. Artifacts and build spec are removed before running the build.
- C. Dynamic Groups access and OCI IAM policies to the code repository are not set.
- D. Source files are connected directly to the build pipeline.
Answer: C
Explanation:
Explanation
The configuration error that could lead to the "unable to clone the repository" error is: Dynamic Groups access and OCI IAM policies to the code repository are not set: This error suggests that the necessary permissions and access controls have not been properly configured for the OCI Code Repository. Dynamic Groups and IAM policies control user access and permissions to various OCI re-sources, including code repositories.
Without the correct configuration, the build pipeline is unable to clone the repository and retrieve the source code. The other options mentioned are not directly related to the error mentioned: More stages were added than required to the build pipeline: Adding more stages to the build pipeline than necessary would not cause an error related to cloning the repository. It might impact the overall flow and logic of the pipeline, but it is not directly related to the repository cloning process. Source files connected directly to the build pipeline:
Connecting source files directly to the build pipeline is a typical setup and would not cause a "unable to clone the repository" error. Artifacts and build spec being removed before running the build: Removing artifacts and build specifications before running the build could impact the build process and result in other errors, but it would not specifically cause an error related to cloning the repository.

NEW QUESTION # 69
You are part of the cloud DevOps team managing thousands of compute Instances running in Oracle Cloud Infrastructure (OCI). The OCI Logging service is configured to collect logs from these Instances using a Unified Monitoring Agent. A requirement has been created to archive logging data into OCI Object Storage.
What OCI capability can help you achieve this requirement?
- A. Service Connector Hub
- B. IAM policy
- C. ObjectCollectionRule
- D. Logging Query
Answer: A
Explanation:
Explanation
"The OCI capability that can help achieve the requirement of archiving logging data into OCI Object Storage is the ""Service Connector Hub."" The Service Connector Hub in OCI enables you to configure connections and workflows between different OCI services. In this case, you can create a connection between the OCI Logging service and OCI Object Storage using the Service Connector Hub. By setting up a connection between these services, you can define a workflow to automatically transfer the logs collected by the Logging service to Object Storage for archiving. This ensures that the logging data is securely stored and easily accessible for future analysis or compliance purposes. The Logging Query capability allows you to search and analyze logs, but it does not directly address the requirement of archiving the logging data into Object Storage.
ObjectCollectionRule is not a valid OCI capability and does not pertain to the archiving of logging data into Object Storage. IAM policies are used to manage access and permissions within OCI, but they do not directly pro-vide the capability to archive logging data into Object Storage." Reference:

NEW QUESTION # 70
You are a developer and have been asked to develop an e-commerce website for your organi-zation. It must support a variety of clients including desktop browsers, mobile browsers and native mobile applications.
Which two approaches can you use to build the application to achieve deployment independence, easier technology upgrades, and resiliency to architecture changes? (Choose two.)
- A. Build the application as a single unit and use container technology to deploy it.
- B. Implement each module as an independent service/process which can be replaced, up-dated, or deleted without disrupting the rest of the application:
- C. Use monolithic approach, as it allows you to easily redeploy your applications to per-form frequent updates.
- D. Use monolithic approach to as it makes it easier to incrementally adapt to newer technology.
- E. Use microservices architecture as it eliminates any long term commitment to a technology stack.
- F. Choose monolithic approach over microservices as it has better fault isolation capability.
Answer: B,E
Explanation:
Explanation
The two approaches that can be used to build the e-commerce website and achieve deployment in-dependence, easier technology upgrades, and resiliency to architecture changes are: Implement each module as an independent service/process: This approach is aligned with the microservices architecture, where each module or functionality is developed and deployed as a separate service. This al-lows for independent updates, replacements, or deletions of specific modules without disrupting the rest of the application. It provides flexibility, scalability, and easier technology upgrades by enabling the use of different technologies and frameworks for different services. Use microservices architec-ture: Microservices architecture involves breaking down the application into smaller, loosely coupled services that communicate with each other through APIs. This architecture promotes independent deployment of services, making it easier to update or modify specific services without affecting the entire application. It allows for better scalability, fault isolation, and resiliency to architecture changes. The monolithic approach, where the entire application is built as a single unit, is not suitable for achieving the mentioned goals. It can lead to challenges in deployment independence, technology upgrades, and adaptability to newer technologies.
NEW QUESTION # 71
Your customer has deployed their microservices based application on Oracle Container Engine for Kubernetes (OKE) and they are using Oracle Cloud Infrastructure Registry (OCIR) service as their Docker image repository. They have deployed the OKE cluster using the 'custom create' option, and their Virtual Cloud Network (VCN) has three public subnets with associated route tables, security lists, and an internet gateway.
They are facing an issue where their application containers are falling to deploy. Upon investigation, they learn that the images are not getting pulled from the designated OCIR repository. The YAML configuration has the correct path to the images. What is a valid concern that needs to be further investigated?
- A. They need to add a security list rule for TCP port 22 to connect to the OCIR service.
- B. They need to add IAM credentials for each user that deploys applications to the OKE cluster.
- C. The OKE cluster needs to have a secret with credentials of their OCIR repository and use that secret in the Kubernetes deployment manifest.
- D. The VCN hosting the OKE cluster worker nodes needs to have a NAT gateway to access OCIR repositories.
Answer: C
Explanation:
Explanation
A valid concern that needs to be further investigated in this scenario is whether the OKE cluster has a secret with credentials of the Oracle Cloud Infrastructure Registry (OCIR) repository and if that secret is being used in the Kubernetes deployment manifest. When deploying an application on OKE and pulling images from OCIR, the cluster needs to authenticate and authorize access to the OCIR repository. This is typically done by creating a Kubernetes secret that contains the credentials (authentication token or username/password) required to access the repository. The secret is then referenced in the Kubernetes deployment manifest to allow the cluster to pull the images. If the images are not getting pulled from the designated OCIR repository, it suggests that the OKE cluster might be missing the necessary secret with the OCIR credentials or the secret is not properly referenced in the deployment manifest. Further investigation should focus on ensuring the existence and correct configuration of the secret and its usage in the deployment process.
NEW QUESTION # 72
As a DevOps Engineer, you need to develop a web app for a company. The web app should support users using mobile browsers and native mobile applications. You need to recommend an architecture which can be easily upgraded, deployed independently and resilient to failures. Which TWO recommendations should you consider? (Choose two.)
- A. Use independent service which can be replaced or updated without any impact on the web app
- B. Prefer Monolithic web app over microservices
- C. Avoid long duration commitment to a technology stack using microservice architecture
- D. Build the web app as one unit and use container technology for deployment
Answer: A,C
Explanation:
Explanation
The two recommendations to consider for developing a web app that supports users on mobile browsers and native mobile applications, and is easily upgradable, independently deployable, and resilient to failures are:
Use independent services: By adopting a microservices architecture, you can break down the web app into smaller, loosely coupled services that can be developed, deployed, and upgraded independently. Each service can focus on a specific functionality or feature of the web app, allowing for easier maintenance, scalability, and resilience to failures. This approach enables you to replace or update individual services without impacting the entire web app. Avoid long duration commitment to a technology stack: By using a microservices architecture, you can avoid long-term commitments to a specific technology stack. Each microservice can be developed using the most suitable technology or programming language for its specific requirements. This flexibility allows you to leverage the latest technologies and frameworks, adapt to changing needs, and take advantage of advancements in the development ecosystem. It also reduces the risk of being locked into a technology stack that may become outdated or less effective over time. Building the web app as one monolithic unit would not provide the desired modularity, independent deployment, and upgradability.
Container technology, such as Docker, can be used in conjunction with the recommended microservices architecture to provide a consistent and portable deployment mechanism, but it is not a standalone recommendation in this case.
NEW QUESTION # 73
As a startup planning to set up your infrastructure on Oracle Cloud Infrastructure (OCI), you must understand the key concepts of OCI Resource Manager. Which best describes a stack in Resource Manager that will assist you to manage infrastructure using the infrastructure-as-code model?
- A. It is a group of related resources used to create lightweight and reusable abstractions, so that you can describe your infrastructure in terms of its architecture.
- B. It represents a request to take a Terraform action on a state. It performs the actions that are defined in the configuration file.
- C. It is the difference between the real-world state of your infrastructure and the last executed Terraform configuration.
- D. It represents a collection of OCI resources created in the Compartment and includes a collection of Terraform files that specify the resources you want to manage with the Resource Manager
Answer: D
Explanation:
Explanation
A stack in Resource Manager is a collection of OCI resources that are created and managed as a single unit in a compartment. A stack includes a collection of Terraform files that specify the resources you want to manage with the Resource Manager, such as compute instances, networks, storage, etc. You can use a stack to apply the infrastructure-as-code model, which allows you to define, provision, and update your infrastructure using configuration files instead of manual processes.

NEW QUESTION # 74
You are processing business transactions within applications deployed to Oracle Container Engine for Kubernetes (OKE). As each batch of 1000 transactions are processed, a status file is created and uploaded to an Oracle Cloud Infrastructure (OCI) Object Storage buck-et. Each time a new file is created, you need to send an email to the customer to indicate final processing status. The solution should require the least amount of development effort, while still providing for a best effort guaranteed delivery. Which approach should be used to trigger these emails?
- A. Create a rule in the OCI Events service that sends the bucket event to an OCI Notifications service topic configured with an email subscriber.
- B. Deploy an Oracle Function that checks the bucket every 60 seconds, then sends an email when a new file is found.
- C. Define and schedule a Cron job that monies the bucket, then sends an email when a new file is found.
- D. Create an alert in the OCI Monitoring service that triggers an email when the monitored bucket is updated.
Answer: A
Explanation:
Explanation
The approach that should be used to trigger emails when a new file is created in an OCI Object Storage bucket is to create a rule in the OCI Events service that sends the bucket event to an OCI Notifications service topic configured with an email subscriber. The OCI Events service is a service that allows you to react to changes in your OCI resources by creating rules that match events of interest and trigger actions based on those events.
The OCI Notifications service is a service that allows you to broadcast messages to distributed components through topics and subscriptions. By using these services together, you can achieve the following workflow:
* Create an OCI Notifications service topic and add an email subscriber with the customer's email address.
* Create an OCI Events service rule that matches the Object Storage bucket event type
"com.oraclecloud.objectstorage.createobject" and specifies the Notifications topic as the action.
* Whenever a new file is created in the Object Storage bucket, an event will be generated and matched by the rule, which will send a message to the Notifications topic.
* The Notifications topic will deliver the message to the email subscriber, which will trigger an email to the customer. Verified References: [Events - Oracle Cloud Infrastructure Developer Tools],

NEW QUESTION # 77
Your organization needs to design and develop a containerized application that requires a connection to an Oracle Autonomous Transaction Processing (ATP) Database. As a DevOps engineer, you have decided to use Oracle Container Engine for Kubernetes (OKE) for the container app deployment and you need to consider options for connecting to ATP. Which connection option is NOT valid?
- A. Enable Oracle REST Data Services for the required schemas and connect via HTTPS.
- B. Use Kubernetes secrets to configure environment variables on the container with ATP instance OCID and OCI API credentials. Then use the CreateConnection API endpoint from the service runtime.
- C. Create a Kubernetes secret with contents from the ATP instance Wallet files. Use this secret to create a volume mounted to the appropriate path in the application deployment manifest.
- D. Install the OCI Service Broker on the Kubernetes cluster and deploy serviceinstance and ServiceBinding resources for ATP. Then use the specified binding name as a volume in the application deployment manifest.
Answer: A
Explanation:
Explanation
The connection option that is NOT valid for connecting to an Oracle Autonomous Transaction Pro-cessing (ATP) Database from Oracle Container Engine for Kubernetes (OKE) is: Enable Oracle REST Data Services for the required schemas and connect via HTTPS. Enabling Oracle REST Data Services (ORDS) is not a valid method for connecting to an ATP Database from OKE. ORDS is a tool that allows you to create RESTful web services against Oracle databases. However, it is not the recommended method for establishing a connection between a containerized application in OKE and an ATP Database. The other three options mentioned are valid approaches: Creating a Kuber-netes secret with contents from the ATP instance Wallet files: This allows you to securely store and use the necessary credentials to connect to the ATP Database in your application's deployment man-ifest. Using Kubernetes secrets to configure environment variables on the container with ATP in-stance OCID and OCI API credentials: This approach allows you to set environment variables with-in your application container to provide the necessary connection details to the ATP Database. In-stalling the OCI Service Broker and deploying serviceinstance and ServiceBinding resources for ATP: The OCI Service Broker simplifies the process of provisioning and managing Oracle Cloud Infrastructure (OCI) services, including ATP, from within Kubernetes. This option allows you to create a service binding that provides the necessary connection information to your application as a volume in the deployment manifest. These options provide more direct and secure connections be-tween the containerized application in OKE and the ATP Database, ensuring proper integration and data access.

- B. Use a single Kubernetes cluster with two node pools, one for the blue environment and one for the green environment.
- C. Deploy the application to two separate OCI tenancies to ensure complete isolation be-tween environments.
- D. Use two separate Oracle Container Engine for Kubernetes (OKE) clusters to ensure complete separation between environments.
Answer: D
Explanation:
Explanation
The recommended approach in OCI for creating identical blue-green environments for deploying a critical application is to use two separate OKE clusters to ensure complete separation between environments. A blue-green environment is a deployment technique that involves creating two identical environments (blue and green) and switching traffic between them after testing. This technique allows you to reduce downtime, minimize risk, and improve user experience. To create blue-green environments in OCI, you can use two separate OKE clusters, one for the blue environment and one for the green environment. Each cluster will have its own set of resources, such as node pools, pods, services, deployments, etc., that are isolated from each other. You can also use OCI Load Balancing service to route traffic between the clusters based on your criteria.

You have a stack in Oracle Cloud Infrastructure (OCI) Resource Manager that is co-managed by multiple teams. Which statement is true?
- A. The resources in the stack can no longer be edited or destroyed through the Terraform CLI on a local machine.
- B. The Terraform state may become corrupted if multiple people attempt Apply jobs in Resource Manager simultaneously.
- C. Resources provisioned by Resource Manager can only be managed through Resource Manager, preventing the state from becoming out of sync.
- D. The resources in the stack can still be edited or destroyed through the OCI console, causing Resource Manager's state to be out of sync.
Answer: C
Explanation:
Explanation
The correct statement is: Resources provisioned by Resource Manager can only be managed through Resource Manager, preventing the state from becoming out of sync. When a stack is co-managed by multiple teams in Oracle Cloud Infrastructure (OCI) Resource Manager, the resources provisioned by Resource Manager can only be managed through Resource Manager itself. This ensures that the state of the stack remains in sync and prevents conflicts that may arise from multiple teams making changes simultaneously. Managing the resources through Resource Manager helps maintain control and consistency over the stack deployment and configuration. Reference:

NEW QUESTION # 81
As a DevOps engineer, you are tasked with creating stages for an Oracle Kubernetes Engine (OKE) deployment pipeline in OCI DevOps. Your goal is to include as many actions as possible within the deployment pipeline stages themselves. Which two stages can you add to achieve this goal?
- A. Add a stage to deploy based on Blue-Green strategy or Canary strategy to OKE environment.
- B. Add a stage to deliver artifacts to an Oracle Cloud Infrastructure (OCI) Artifact Regis-try.
- C. Add a stage to apply the container image to the Kubernetes cluster
- D. Add a stage to deploy incrementally to multiple OKE target environments.
- E. Add a stage to apply the Kubernetes manifest to the Kubernetes cluster.
Answer: A,E
Explanation:
Explanation
To create stages for an OKE deployment pipeline in OCI DevOps, you can add the following stages:
* Add a stage to deploy based on Blue-Green strategy or Canary strategy to OKE environment. A Blue-Green strategy is a deployment technique that involves creating two identical environments (blue and green) and switching traffic between them after testing. A Canary strategy is a deployment technique that involves releasing a new version of the application to a subset of users (canaries) and monitoring their feedback before rolling out to the rest of the users. You can use these strategies to reduce downtime, minimize risk, and improve user experience.
* Add a stage to apply the Kubernetes manifest to the Kubernetes cluster. A Kubernetes manifest is a YAML or JSON file that defines the desired state of your Kubernetes resources, such as pods, services, deployments, etc. You can use this stage to apply the manifest file to your OKE cluster using kubectl or helm commands.
