Build Docker Images

Build the custom docker images for the Jenkins Manager and the Jenkins Agent, and then push the images to AWS ECR Repository. Navigate to the docker/ directory, then execute the command according to the required parameters with the AWS account ID, repository name, region, and the build folder name jenkins-manager/ or jenkins-agent/ that resides in the current docker directory. The custom docker images will contain a set of starter package installations.

  • Build a docker image and push to the AWS ECR Repository. Replace the Repository Name and Region for Jenkins Manager.
