Delete CloudFormation stacks action

This action deletes all cloudformation xx/pr stacks in the provided region with the given name prefix + the stage suffix. The stage is transformed from the branch name (eg. #85-my-feature > xx85 / pr85). Production branch (master | main) branch is always ignored.

Make sure your CloudFormation Stacks are fully deletable (if autoDeleteBuckets=true also autoDeleteItems, etc.)

Usage

Inputs

stackNamePrefix

Requiredstring The prefix of the stack names to delete.

waitForDeleteComplete

Optionalboolean Whether the action should wait until the stack is completely deleted (status=DELETE_COMPLETE).

ignoreBranches

OptionalJSON String Array branches to ignore (early exit, necessary since on-delete workflows do not support branch restrictions). Production branches (master | main) branch is always ignored.

Example workflow step config

- name: Configure AWS Credentials
uses: aws-actions/configure-aws-credentials@<latest-version>
with:
role-to-assume: 'arn:aws:iam::{ACCOUNT_ID}:role/{ROLE_NAME}'
aws-region: eu-central-1
- name: Delete Stacks
uses: shiftcode/delete-cfn-stacks-action@v0.0.X
with:
stackNamePrefix: 'ch-website'
waitForDeleteComplete: true
# master & main are ignored by default
ignoreBranches: '["#1-dev"]'

Hints

• If there are stacks in multiple regions: use both actions two times with their corresponding region.
• If working with assumedRoles and aws-actions/configure-aws-credentials@v1 the policy statement for the static iam user needs to have the actions "sts:AssumeRole AND sts:TagSession allowed on the role to assume. The Trust relationship of the assumed role needs to allow those actions for the assuming user.

Development

testing

To test the action locally: call index.js with env var INPUT_STACKNAMEPREFIX --> INPUT_STACKNAMEPREFIX="bag-covid19" node ./dist/index.js
