Flagops can be natively integrated into ArgoCD as a config plugin. This allows ArgoCD to pass manifests through flagops to natively integrate feature flags into the gitops process.
You can install flagops as a sidecar container plugin for argocd using the manifests in the /manifests directory.
The configuration of the plugin types is controlled via the config maps in cmp-plugin.yaml. You can edit the flagops-env config map to contain your environment configuration for the plugins.
The argocd-repo-server.yaml file contains a kustomize patch for the argocd-repo-server to add the sidecar applications and configs. This patch should not need to be configured and can be applied as is.
Once the manifests have been configured you can install the plugin with kustomize build manifests | kubectl apply -. This will spin up an argocd server with the plugin installed.
