1. image-automation-controller detects image updates, checks out from the master branch and pushes to the sample-merge branch.
2. Create and merge a PR from the sample-merge branch to the master branch.
3. The developer checks out the feature branch from the master branch and pushes the file containing the symlink to the feature branch.
4. Create and merge PR from feature branch to master branch
5. Application image is updated
6. image-automation-controller detects image updates, checks out from the master branch and pushes to the sample-merge branch.

At this time, the symlink committed by the developer in step 3 is pushed to the sample-merge branch.
