How to push docker image tagged after git branch?

Sergey Mokhov

Hi everyone!

We are in the middle of transition to bitbucket pipelines.

We build docker images from every git branch and run tests against these images. To make tracking of what image was build from what branch easier we tag docker images with git branch name it was built from.

The problem is that feature branches have slash "/' in their name and slash is not allowed in docker image tag. What we used to do is replace slashes with dashes and use that as a tag.

One option for us would be to use a script that does that substitution and pushes image, but we would have to put that script in every repository.

To use pipe atlassian/aws-ecr-push-image:1.2.2 we tried to define tags as

TAGS: '${BITBUCKET_BRANCH//\//-}'
or
TAGS: ${BITBUCKET_BRANCH//\//-}

but it does not work and build fails with

<span>Image not found: 404 Client Error: Not Found </span>

<span>Image not found: 404 Client Error: Not Found ("no such image: whatever: No such image: whatever:latest")</span>

 We also tried to add a separate step that does replacement and exports result as  another variable, but that did not work either.

Changing naming convention would cause a lot of pain, many scripts rely on existing scripts rely on that naming convention.

@Sergey Mokhov I guess you want something like changing,e.g

feature/jira-story-333 to feature-jira-story-333.

You can define another local variable to substisute, BUT with proper escaping before executing pipe, like

script:

 - deploy_tag="${BITBUCKET_BRANCH/\//-}"

- pipe: atlassian/aws-ecr-push-image:1.2.0

  variables:

      ....

      TAGS: $deploy_tag

  .....

for me replacing worked all right:

BITBUCKET_BRANCH=feature/check-branch

branch="${BITBUCKET_BRANCH/\//-}"
echo "branch is" $branch
branch is feature-check-branch

Perhaps, passing such substitution right in the variables does not work, but try to initialize this variable and let's see. In the pipe we accept this variable as string and I am not sure it is acceptable to pass value as a variable and it will be transformed on the fly. So then try just with local var initializing.

 

Also, please share logs after the execution if it fails.
