Similar bug to https://github.com/CircleCI-Public/aws-ecs-orb/issues/206

[Sirafe]

Orb version

9.0.2

What happened

Having the same issue with aws-ecr/build_and_push_image that the reporter for the ECS orb was having here with service_update and the ${CIRCLE_SHA1} @ CircleCI-Public/aws-ecs-orb#206
- aws-ecr/build-and-push-image:
checkout: false
auth:
- aws-cli/setup:
aws_access_key_id: AWS_ACCESS_KEY_ID
aws_secret_access_key: AWS_SECRET_ACCESS_KEY
region: AWS_REGION
dockerfile: Dockerfile-app
path: ~/project
repo: $repo
push-image: false
region: $region
tag: ${CIRCLE_SHA1:0:7}

Expected behavior

Using ${CIRCLE_SHA1:0:7} Should return only the first 7 characters of the hash. Instead it is returning the full hash.

Additional Information

Expected behavior works with previous version 8.2.1

[rel1c]

I believe this has to do with the change from eval to env subst. For the meantime, I was able to create a stop gap by inlining the 8.2.1 aws-ecr orb and updating the Ubuntu executor images to current.

@Sirafe FWIW, we got around this by injecting the variables before the orb:

    - setup_remote_docker
    - run:
        name: Get 7 digit git sha1
        command: |
          echo 'export SMALL_SHA="${CIRCLE_SHA1:0:7}"' >> "$BASH_ENV"
    - aws-ecr/build_and_push_image:
        - tag: ${SMALL_SHA}
