Get base docker image on Linux buildbox

We will be using ubuntu:24.04 as the required base image for Linux.

• Log in to the server where internet or Docker registry access is available, and ensure the server is reachable from the build box.
• Open a terminal and log in to the registry (if available) using the docker login command.

• Pull the ubuntu:24.04 image

  docker pull ubuntu:24.04
  

  

• Save the image as a .tar file.

  docker save -o base-image.tar ubuntu:24.04
  

  

• Copy the .tar file to the build box.

• Load the copied .tar file on the build box to make the base image available.

  docker load -i base-image.tar
  

  

Verify new loaded base image using command docker images.

Use or update the base image as needed

• Navigate to Projects → Desired project → Transform → Components → Click on the 'Containerize' button next to the component.

• Select the profile you want to containerize → In the 'Dockerfile' section, you will find the base Docker image starting with 'FROM' → Click on the 'Edit' button at the bottom to edit the Dockerfile.

• Edit the dockerfile and update the old base image to new desired base image -> Click on 'Save' button at the bottom.

Done. The updated base image will be used for Transformation phase.
