Pull Request Operator

The Pull Request operator checks a target branch in a repository for new pull requests at a specified interval.

Installation

Run the following command:

kubectl apply -f https://github.com/jquad-group/pullrequest-operator/releases/latest/download/release.yaml

The operator is installed in the pullrequest-operator-system namespace.

After the installation of the operator, the PullRequest resource is added to the kubernetes cluster.
