How to cut a Webhook RC

Cutting a new Webhook RC

1. Determine the next RC for the desired line.
   

   • If the last tag was v0.3.5-rc2, then the next tag will be v0.3.5-rc3
   • If the last tag was a release with no RC v0.3.3, then ask one of the code owners of rancher-webhook which tag to use.
     
     

   Rancher Version	Webhook Branch
   v2.7	release/v0.3
   v2.6	release/v0.2
   v2.5	release/v0.1

2. On your local machine checkout and pull the latest changes for the desired release branch.

3. Tag HEAD

   • git tag v0.3.5-rc3

4. Push the new tag to upstream

   • git push upstream v0.3.5-rc3

5. Wait for CI pipeline started by the new tag to complete.

   • This will create a new release and artifacts needed for the next steps https://github.com/rancher/webhook/releases/tag/v0.3.5-rc3

Create a new Chart for the new tag

1. Checkout the dev branch for the desired charts line on your local fork.
   • For this example, we are on (https://github.com/rancher/charts/tree/dev-v2.7)
2. Create a new branch for your changes.
   • git checkout -b bump-rancher-webhook-v0.3.5-rc3
3. In the new charts branch, update release.yaml and package.yaml with the new RC and commit your changes.
   • If this is the first RC, also bump the chart version. and add a new item for rancher-webhook in release.yaml
   • commit package.yaml and release.yaml and package message=“Bump Rancher-webhook to v0.3.2-rc5”
   • https://github.com/rancher/charts/pull/2605/commits/ed82e962e51a69a53d0afbabeed3aaa2ae657f80
4. Run Make Charts and commit your changes.

5. Remove previous RC (unless this is the first RC)
   • export CHART=rancher-webhook && export VERSION=<rc-to-remove> && make remove
   • The VERSION can be found in assets/rancher-webhook. It's the string after rancher-webhook- ie 103.0.0+up0.4.0-rc6
