docker push with AWS CodeBuild fails with exit status 1

I created my CodeBuild project triggered by CodePipeline and the 'docker push' step always fails with the 'Reason: exit status 1' error message

Here are my build logs (replaced my org id by <MY_ORG_ID>):

[Container] 2021/06/12 14:39:47 Entering phase INSTALL

And here is my buildspec.yaml:

version: 0.2

env:
  git-credential-helper: yes
phases:
  pre_build:
    commands:
      - echo Logging in to Amazon ECR...
      - aws ecr get-login-password --region eu-west-2 | docker login --username AWS --password-stdin <MY_ORG_ID>.dkr.ecr.eu-west-2.amazonaws.com
  build:
    commands:
     - echo Pushing Docker image <MY_ORG_ID>.dkr.ecr.eu-west-2.amazonaws.com/reponame/core-service:latest
    - DOCKER_REPO=<MY_ORG_ID>.dkr.ecr.eu-west-2.amazonaws.com
    - IMAGE_TAG=${DOCKER_REPO}/reponame/core-service:${EKS_CLUSTER_NAME}-${CODEBUILD_RESOLVED_SOURCE_VERSION}-v${CODEBUILD_BUILD_NUMBER}
    - echo Set IMAGE TAG = $IMAGE_TAG
    - docker build --build-arg NODE_ENV=production --build-arg DOCKER_REPO=${DOCKER_REPO} -t $IMAGE_TAG core-service/.
  - docker push $IMAGE_TAG

As many references point out, I have added this statement to the policy attached to the corresponding AWS CodeBuild service role but it still does not work.

{
  "Statement": [
    ### BEGIN ADDING STATEMENT HERE ###
    {
      "Action": [
        "ecr:BatchCheckLayerAvailability",
        "ecr:CompleteLayerUpload",
        "ecr:GetAuthorizationToken",
        "ecr:InitiateLayerUpload",
        "ecr:PutImage",
        "ecr:UploadLayerPart"
      ],
      "Resource": "*",
      "Effect": "Allow"
    },
    ### END ADDING STATEMENT HERE ###
    ...
  ],
  "Version": "2012-10-17"
}

I can run these steps manually but it always gives me this error on CodeBuild.

Please, if you could help, there are similar threads out there but none could explain a solution for this one specifically. Thanks.

The issue could be the with policy which is not define access to ECR. that could help, but keep in mind it provides full access to ECR:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "VisualEditor0",
            "Effect": "Allow",
            "Action": "ecr:*",
            "Resource": "*"
        }
    ]
}

I am sure at least you need those:

"ecr:GetAuthorizationToken"
"ecr:BatchCheckLayerAvailability",
"ecr:BatchGetImage",
"ecr:CompleteLayerUpload",
"ecr:GetDownloadUrlForLayer",
"ecr:InitiateLayerUpload",
"ecr:PutImage",
"ecr:UploadLayerPart"

Some details might be found here

Some details about access can be found here as well

As you can see from the error message, trying to push the image with this tag was throwing an error:

<MY_ORG_ID>.dkr.ecr.eu-west-2.amazonaws.com/reponame/core-service:latest

That was happening because the image tag 'latest' already existed in my repo.

By running multiple times the same docker push command, I saw that sometimes CodeBuild would print the full error message and sometimes not. Pushing an unique image name tag solved the issue:

<MY_ORG_ID>.dkr.ecr.eu-west-2.amazonaws.com/reponame/core-service:${CODEBUILD_RESOLVED_SOURCE_VERSION}-v${CODEBUILD_BUILD_NUMBER}

Everything was fine with permissions and authentication.
