How to keep multiple repositories in sync

In a recent Adobe Experience Manager project, there were multiple security restrictions with access, so we enabled a repository for each team to work on the project and enable every organization to manage the permissions.

Additionaly, in AEM as a Cloud Service, there is also a Cloud Manager repository that needs to be kept in sync to trigger the deployment to the managed instances.

We used a continuous integration pipeline to ensure the code repositories were in sync. Below is a diagram with the workflow that was implemented:

To make it work we enabled bitbucket pipelines, configured the repository variables and updated the content of the bitbucket-pipelines.yml file:

definitions:
  steps:
    - step: &sync-remote-adobe
        name: Push to Adobe Experience cloud
        script:
          - if [[ $ADOBE_CM_GIT_SLUG ]]; then
          - git remote add adobe https://$ADOBE_CM_USERNAME:$ADOBE_CM_PASSWORD@git.cloudmanager.adobe.com/$ADOBE_CM_GIT_SLUG
          - git pull adobe $BITBUCKET_BRANCH --tags
          - git push adobe $BITBUCKET_BRANCH --tags
          - else
          - echo "Step skipped, ADOBE_CM_GIT_SLUG variable not configured"
          - fi

    - step: &push-bitbucket-mirror
        name: Push to Bitbucket Mirror
        script:
          - if [[ $MIRROR_GIT_SLUG ]]; then
          - git remote add mirror https://x-token-auth:$MIRROR_TOKEN@bitbucket.org/$MIRROR_GIT_SLUG
          - git push mirror $BITBUCKET_BRANCH --tags
          - else
          - echo "Step skipped, MIRROR_GIT_SLUG variable not configured"
          - fi

pipelines:
    branches:
      develop:
        - step: *push-bitbucket-mirror
        - step: *sync-remote-adobe
      master:
        - step: *push-bitbucket-mirror
        - step: *sync-remote-adobe

Bonus: Sync repositories using github actions

If you’re looking on how to keep different repositories in sync but and the repositories are hosted on github, you can use the mirror-repository action.

Below is a template to configure it with only 2 steps:

1. Commit a file with the configuration:

.github/workflows/mirror-repo-sync.yml

on:
  push:
    branches:
      - develop

jobs:
  sync_to_mirror:
    runs-on: ubuntu-20.04
    steps:

    steps:
      - uses: actions/checkout@v3
        with:
          fetch-depth: 0
      - uses: yesolutions/mirror-action@master
        with:
          REMOTE: ${{ secrets.GIT_REPO }}
          GIT_USERNAME: ${{ secrets.GIT_USERNAME }}
          GIT_PASSWORD: ${{ secrets.GIT_PASSWORD }}
