Service role:

For the implications on the build process of correctly configuring the service role, see:

CodeBuild Service Role

Allow AWS CodeBuild to modify this service role so it can be used with this build project. If selected, the console configuration code updates the role so it contains the appropriate policies.

If you get:

The policy's default version was not created by enhanced zero click role creation or was not the most recent version created by enhanced zero click role creation.

unselect "Allow AWS CodeBuild to modify ..."

Troubleshooting

Generic troubleshooting advice:

ECR AccessDeniedException

An error occurred (AccessDeniedException) when calling the GetAuthorizationToken operation: User: arn:aws:iam::673499572719:user/codebuild-p2 is not authorized to perform: ecr:GetAuthorizationToken on resource: *

Add ecr:GetAuthorizationToken for the user in question to the build role. These are extremely lax permissions, it could be further tightened up:

{
 ...
 "Sid": "VisualEditor1",
 "Effect": "Allow",
 "Action": "ecr:*",
