Bitbucket Pipelines - steps - docker - cant find image

[Steve Stokes]

I'm building my pipline to create a docker image, then push it to AWS. I have it broken into steps, and in Bitbucket, you have to tell it what artifacts to share between them. I have a feeling this is a simple bug, but I just cannot figure it out.

It's failing at 'docker tag' in step 4 with:

docker tag $DOCKER_PROJECT_NAME:v.$BITBUCKET_BUILD_NUMBER $AWS_REGISTRY_URL/$DOCKER_PROJECT_NAME:v.$BITBUCKET_BUILD_NUMBER
Error response from daemon: No such image: projectname:v.11

Basically it cannot find the docker image created...

Here's my pipeline script (some of it simplified)

image: atlassian/default-image:latest

options:
  docker: true

pipelines:
  branches:
    dev:          
      - step:
         name: 1. Install dotnet
         script:
           # Do things

      - step:
         name: 2. Install AWS CLI
         script:
           # Do some more things

      - step:
         name: 3. Build Docker Image
         script:
           - export DOCKER_PROJECT_NAME=projectname

           - docker build -t $DOCKER_PROJECT_NAME:latest -t $DOCKER_PROJECT_NAME:v.$BITBUCKET_BUILD_NUMBER .
         artifacts:
           - ./**

      - step:
         name: 4. Push Docker Image to AWS
         script:
           # Tag and push my docker image to ECR
           - export DOCKER_PROJECT_NAME=projectname
           - docker tag $DOCKER_PROJECT_NAME:v.$BITBUCKET_BUILD_NUMBER $AWS_REGISTRY_URL/$DOCKER_PROJECT_NAME:v.$BITBUCKET_BUILD_NUMBER
           - docker push $AWS_REGISTRY_URL/$DOCKER_PROJECT_NAME:v.$BITBUCKET_BUILD_NUMBER

Now, I know this script works, but only if I remove all the steps. For whatever reason, step 4 doesn't have access to the docker image created in step 3. Any help is appreciated!

The state of one step is not carried to the next. So you'll need to combine step 3 and step 4 together in order to tag and push the built image. In any subsequent steps, you can then pull the image and operate on it (perhaps to retag the image for a deployment step).
