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.

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.

The steps that you would take to delete the specified image are:

• To determine which container is using the image, use the “docker ps -a” command. This command will list all the containers in your system, including their ID, image name, status, etc. You can look for the container that has the image name d123f4e55e12 in its output.
• To delete the container, use the ‘docker rm 0f1262bd1285’ command. This command will remove the container with the ID 0f1262bd1285 from your system. You can also use the -f flag to force remove the container if it is running or paused.
• To delete the docker image, use the ‘docker rmi d123f4e55e12’ command. This command will remove the image with the ID d123f4e55e12 from your system. You can also use the -f flag to force remove the image if it is being used by another container.
