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.

Explanation

To add approvers to the approval workflow in the Deployment Pipeline of Oracle Cloud Infrastructure (OCI) DevOps service, you can follow this approach: Add approvers to the Deployment Pipe-line and give them access via OCI IAM policy. OCI DevOps allows you to define an approval workflow as part of the Deployment Pipeline. To add approvers, you can configure the appropriate settings in the Deployment Pipeline configuration. This typically involves specifying the names or email addresses of the individuals who should review and approve the deployment. These approvers will be notified when a deployment is triggered and will be able to review and provide their approval. In order to give the approvers access to the Deployment Pipeline, you can use OCI's Identity and Access Management (IAM) service. By creating IAM policies, you can grant the necessary permissions and access control to the designated approvers, ensuring that they have the appropriate level of access to review and approve deployments. The other options mentioned are not the correct approaches: Manually adding approvers' names and email addresses in the Deployment Pipeline page: This would not provide the necessary access and permissions for the approvers to review and approve the deployment. IAM policies should be used for access control. Emailing approvers before running the Deployment Pipeline: Emailing approvers separately would not integrate with the auto-mated approval workflow in the Deployment Pipeline. The approval process should be handled within the OCI DevOps service. Adding approvers to the buildspec file: The buildspec file is primarily used for defining the build stages and actions, not for managing the approval workflow.

Explanation

The root cause for the error committed by the fresher is that the expected input/exported variable of a build is not persistent throughout multiple pipelines. This means that the value set for a variable in one pipeline is not carried over to subsequent pipelines, leading to failures in the build pipelines.

To securely store and version your application and automatically build, test, and deploy your application to OCI, you can choose the following OCI services:

• DevOps: This service enables you to automate the software development lifecycle (SDLC) and deliver software faster and more reliably. You can use DevOps to create projects, repositories, build pipelines, deployment pipelines, triggers, and artifacts.
• Oracle Cloud Infrastructure Registry: This service is a private Docker registry that allows you to store and manage your Docker images in OCI. You can use Registry to push and pull images from your local machine or from your build pipelines.
• Container Engine for Kubernetes: This service is a fully-managed platform that allows you to run your containerized applications in OCI. You can use Container Engine for Kubernetes to create and manage Kubernetes clusters, pods, services, and deployments.

Explanation

The possible problem that caused the failure of the managed build stage in an Oracle Cloud Infra-structure (OCI) DevOps Build Pipeline could be that a vault secret has an incorrect OCID assigned to it. In the context of the question, the issue is related to the code repository not being accessible. This suggests that there might be a problem with the authentication or credentials used to access the code repository. One possible cause is that a vault secret, which typically stores sensitive information such as credentials or access tokens, has an incorrect OCID (Oracle Cloud Identifier) as-signed to it. If the secret's OCID is incorrect or doesn't match the expected value, it can result in authentication failures and the inability to access the code repository, leading to a pipeline failure. To resolve this issue, the administrator or developer should verify the OCID assigned to the vault secret and ensure it is correct. They should also check the code repository configuration and ensure that the correct credentials are being used to access the repository.

Explanation

The two tools that should be used for leveraging OCI DevOps service and including a Kubernetes cluster in the deployment architecture are: Ansible Collection: Ansible is an open-source automation tool that can be used for configuration management, application deployment, and orchestration. The Ansible Collection for OCI provides pre-built Ansible modules specifically designed for managing resources in Oracle Cloud Infrastructure. It enables automation of provisioning and managing OCI resources, including the setup and configuration of a Kubernetes cluster. Terraform Provider: Terraform is an infrastructure as code tool that allows you to define and provision infrastructure re-sources using declarative configuration files. The Terraform Provider for OCI enables you to define and manage OCI resources, including the creation and configuration of a Kubernetes cluster. It pro-vides a consistent and repeatable way to provision and manage infrastructure components. Chef Knife Plug-in and Compute Jenkins Plug-in are not specifically related to managing resources in OCI or deploying a Kubernetes cluster, so they are not the appropriate tools in this scenario.

Explanation

The correct statement is: You need to provision a new stack because Terraform uses immutable in-frastructure. In Oracle Cloud Infrastructure (OCI) Resource Manager, Terraform uses the concept of immutable infrastructure, which means that any changes to the infrastructure are managed through the Terraform code. In this scenario, if you want to add a CIDR block, subnet, and compute instance to your VCN, you would need to make the necessary changes to your Terraform code, create a new stack in Resource Manager, and deploy the updated code. This ensures that the infra-structure is created consistently and according to the desired state defined in the Terraform code. Simply provisioning the new resources in the OCI console and later adding them to the Terraform configuration and state would not be the recommended approach in this case.
