argocd-hello-extension

A "hello-world" Argo CD extension.

Prerequisites

• Argo CD version 2.6+

Quick Start

Install UI extension

The UI extension needs to be installed by mounting the React component in Argo CD API server. This process can be automated by using the argocd-extension-installer. This installation method will run an init container that will download, extract and place the file in the correct location.

Add containerInit and the new extension volumen to the already existent deployment:

kubectl get deployment argocd-server -o yaml -n argocd > deployment.yaml

      container:
      ...
      volumeMounts:
        ...
      - name: extensions
        mountPath: /tmp/extensions/
      initContainers:
        - name: hello-extension
          image: quay.io/argoprojlabs/argocd-extension-installer:v0.0.1
          env:
          - name: EXTENSION_URL
            value: https://github.com/jsolana/argocd-hello-extension/releases/download/v0.0.1/extension.tar
          volumeMounts:
            - name: extensions
              mountPath: /tmp/extensions/
          securityContext:
            runAsUser: 1000
            allowPrivilegeEscalation: false
      volumes:
        - name: extensions
          emptyDir: {}

Install extension locally using kind

Install Arco CD in a k8s cluster locally using kind

    kubectl create namespace argocd
    kubectl apply -n argocd -f https://raw.githubusercontent.com/argoproj/argo-cd/v2.10.0-rc1/manifests/install.yaml

    kubectl port-forward svc/argocd-server -n argocd 8080:443
    kubectl get secret argocd-initial-admin-secret -n argocd -o jsonpath='{.data.password}' | base64 -d
