This is a microservice designed to create new branches in a CDK construct when a new version of the CDK core packages are published. Details on this microservice and what it does can be found at this blog.
If you'd like to use this code start by putting in a PR to have your AWS account added to a list of allowed external accounts that can be subscribed to the Construct Catalog topic. The code change is here.
Then you can synth the app, providing two context variables:
- 'topicArn' for the topic to listen to. You can choose any topics as long as it publishes messages this schema like:
{
"name": "@aws-cdk/core",
"version": "1.97.0"
}If you're subscribing to the Construct Catalog topic, use arn:aws:sns:us-east-1:499430655523:construct-catalog-prod-RendererTopicD9CB70E6-TTOURYQEX9K1
- 'repository' for the SSH address of the repository to update. For example,
git@github.com:mbonig/rds-tools.git
For example, you could run:
cdk synth -c repository=git@github.com:mbonig/rds-tools.git -c topicArn=arn:aws:sns:us-east-1:499430655523:construct-catalog-prod-RendererTopicD9CB70E6-TTOURYQEX9K1You will need an SSH keypair to push the new branch to the repository. After your stack is created, update the secret
called auto-brancher-<your repo name>/deploy-key with the private side of your keypair. The public key should be
setup with your repository provider, like Github.
This microservice is used in conjunction with a Github Action to automate the bumping of CDK dependencies. You can see an example of this Github Action definition in the rds-tools repository.
If you have any problems, please open an Issue on Github. PRs are always welcome.
