Provider ArgoCD

Overview

This is a Kubernetes Operator (Crossplane provider) that creates API tokens for specific ArgoCD users.

The provider that is built from the source code in this repository adds the following new functionality:

• a Custom Resource Definition (CRD) that model ArgoCD auth tokens for specific users

Getting Started

With Crossplane and ArgoCD installed in your cluster:

$ helm repo add crossplane-stable https://charts.crossplane.io/stable
$ helm repo update
$ helm install crossplane --namespace crossplane-system crossplane-stable/crossplane

$ kubectl create namespace argo-system
$ kubectl apply -n argo-system -f https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/install.yaml

How to install this provider

$ kubectl apply -f ./examples/provider.yaml

Replace VERSION tag with the desired release.

Configure this operator with serverUrl pointing to an ArgoCD instance

$ cat <<EOF | kubectl apply -f -
apiVersion: argocd.krateoplatformops.io/v1alpha1
kind: ProviderConfig
metadata:
  name: provider-argocd-token-config
spec:
  serverUrl: https://argocd-server.argo-system.svc:443
  credentials:
    source: Secret
    secretRef:
      namespace: argo-system
      name: argocd-initial-admin-secret
      key: password
EOF

Create a new ArgoCD account

Following the steps in the official ArgoCD documentation you can create a new user defining it in the argo-cm ConfigMap:

$ cat <<EOF | kubectl apply -f -
apiVersion: v1
kind: ConfigMap
metadata:
  name: argocd-cm
  namespace: argo-system
  labels:
    app.kubernetes.io/name: argocd-cm
    app.kubernetes.io/part-of: argocd
data:
  accounts.krateo-dashboard: apiKey, login
EOF

Each user might have two capabilities:

• apiKey: allows generating authentication tokens for API access
• login: allows to login using UI

Create an API token without expiration that can be used by the defined user

$ cat <<EOF | kubectl apply -f -
apiVersion: argocd.krateoplatformops.io/v1alpha1
kind: Token
metadata:
  name: krateo-dashboard-argocd-token
spec:
  forProvider:
    account: krateo-dashboard
    writeTokenSecretToRef:
      name: krateo-dashboard-argocd-token
      key: authToken
      namespace: krateo-system
  providerConfigRef:
    name: provider-argocd-token-config
EOF

After a while check if the API token is created

$ kubectl get secrets/krateo-dashboard-argocd-token -n krateo-system \
   --template='{{.data.authToken | base64decode}}'
