Argo CD Application Controller Custom Sharding

This short Go program uses a Fist-fit-decreasing Bin Packing algorithm to assign Kubernetes clusters to different Argo CD Application Controller shard based on their resources count. It bases its calculations on the output of the argocd-util cluster stats command. The output can be used to update the undocumented shard key of the cluster secrets.

Example usage

argocd-util cluster stats --namespace=argocd | go run reshard.go

The go command line tool needs to be able to fetch dependencies from your private GitLab, but authenticaiton is required.

This assumes your private GitLab is hosted at privategitlab.company.com.

The following environment variables are recommended:

MicroService Proxy Gateway Solutions

Kong, Traefik, Caddy, Linkerd, Fabio, Vulcand, and Netflix Zuul seem to be the most common in microservice proxy/gateway solutions. Kubernetes Ingress is often a simple Ngnix, which is difficult to separate the popularity from other things.
