ArgoCD is a declarative, GitOps continuous delivery tool for Kubernetes. ArgoCD is implemented as a Kubernetes CRD (Custom Resource Definition).

ApplicationSet

• ArgoCD: Pull Request ApplicationSet: Using an ApplicationSet we can automatically create templated Applications based on Pull Requests
• ArgoCD: ApplicationSet definition: Using ApplicationSet we can use a template to automate the Application generation

Application

• ArgoCD Application: render a helm chart with Kustomize: To render a helm chart using kustomize in ArgoCD we'll have to add the --enable-helm flag
• ArgoCD: phases and sync waves: phases and sync waves can set the apply order for objects managed by ArgoCD
• ArgoCD use commit id as a variable: We can use the commit hash to set a helm chart value
• ArgoCD: Application definition: Using ArgoCD we can deploy applications using helm from a remote git repository

Installation

• ArgoCD: redirect loop: Enabling ArgoCD's ingress can be tricky if we use an Ingress controller that offloads the HTTPS connection
