⚠ BREAKING CHANGES

several breaking changes with details below

There are several breaking changes in this release.

  1. Replace noDiffForStages with stackSelectionStrategy & stackSelectorPatterns This uses the native selection stack filtering capability of toolkit-lib and should be a more robust option for users to filter stacks. stackSelectorPatterns also uses a multi-line input instead of a comma delimited string input. To migrate from noDiffForStages to stackSelectorPatterns you can do this:
# from this
- name: Diff
   uses: corymhall/cdk-diff-action@v1
   with:
     noDiffForStages: "Stage1,Stage2"
     githubToken: ${{ secrets.GITHUB_TOKEN }}

# to this
- name: Diff
   uses: corymhall/cdk-diff-action@v2
   with:
     stackSelectorPatterns: |
       !Stage1/*
       !Stage2/*       
     githubToken: ${{ secrets.GITHUB_TOKEN }}
  1. The default diffMethod is changed to change-set to match the cdk default behavior. This also changes the IAM Role used for diff from the lookup-role to the deploy-role. To keep the old behavior you can specify diffMethod: template-only
  2. allowDestroyTypes and noFailOnDestructiveChanges input types were changed from a comma delimited string to a multi-line string.
# from this
- name: Diff
   uses: corymhall/cdk-diff-action@v1
   with:
     noFailOnDestructiveChanges: "Stage1,Stage2"
     githubToken: ${{ secrets.GITHUB_TOKEN }}

# to this
- name: Diff
   uses: corymhall/cdk-diff-action@v2
   with:
     noFailOnDestructiveChanges: |
       Stage1
       Stage2       
     githubToken: ${{ secrets.GITHUB_TOKEN }}
