    Preview manifests before applying them with ArgoCD

  • What you didn’t know is that there is a downstream Kustomize overlay that also defines replicas on its own. So the proposed change has no effect at all. The problem was that the pull request contains only the segment of a Kustomize source manifest and doesn’t show a diff for the end result (the full rendered manifest).

  • The solution is to use 2 GitOps repositories, for each application/cluster. One git repository has the manifests in their unprocessed form (e.g. as Kustomize overlays) as before. There is now a second Git repository that has the final rendered manifests. And Argo CD is pointed at the latter.

  • InfluxDB

    Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

    Terraform Pull Request Automation

  • This workflow is so common that an open source project – https://www.runatlantis.io/ does exactly that.

  • WorkOS

    The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.
