Integrating Argo CD with Jenkins or GitHub Actions bridges CI (build) and CD (deployment) workflows. In Jenkins, you can trigger Argo CD syncs automatically after a successful build using Argo’s REST API or CLI. With GitHub Actions, simply use a workflow file to call Argo CD’s sync command when code is merged into the main branch. This ensures that your deployments happen right after testing and building are complete. Such integrations improve automation, reduce manual steps, and keep your clusters always up-to-date with the latest version of your application.
