Argo CD Application Updater

Warning

I am using Renovate now and this project is no longer in use / supported

NodeJS command line application that checks all Argo CD application manifests in the directory it's being run in for an update of the target revision. It then updates the application manifest and writes it back to git. A pull request can be created by passing push options for GitLab or using Actions for GitHub.

Supported application types

• Helm

Running locally

• npm install
• npm run build
• npm link
• cd to the repository that contains the Argo CD application manifests
• argocd-application-updater

Running on GitLab CI

These steps have to be executed in the repo that contains the Argo CD application manifests.

• Create a deploy key with write access (https://docs.gitlab.com/ee/user/project/deploy_keys) or use the SSH key of a CI only user.
• Add the private part as a CI variable under the name CI_SSH_PRIVATE_KEY
• Add the example below to .gitlab-ci.yml and fill in the blanks
