Continuous deployment

Accessing ArgoCD

First, acquire credentials for ArgoCD by running the get credentials command:

xctl --context env.yaml get credentials argocd

After you've gotten the credentials, open a tunnel to the ArgoCD instance by running the following command:

xctl --context env.yaml forward argocd

Bootstrapped ArgoCD applications

Applications

This ArgoCD application tracks the /infrastructure/<environment name>/argocd/applications/ directory. This directory contains ArgoCD applications referencing actual applications. This setup has the following effects:

• We can deploy a new application without administrating the environment directly by adding an ArgoCD application manifest to this directory
• This renders the ArgoCD setup stateless, meaning we can upgrade ArgoCD by toggling the integration off and on again in the environment.yaml manifest.

Namespaces

The namespaces ArgoCD application tracks the /infrastructure/<environment name>/argocd/namespaces/ directory. This directory contains Kubernetes manifests defining all namespaces in the cluster. This lets us disassociate a namespace from an application, allowing namespaces to outlive an application in the case where multiple applications reside in the same namespace, but one is deleted.
