Install with ArgoCD

Prerequisites

  • Your workstation: Install the Argo CD CLI.
  • Kubernetes cluster:
    • Ensure that each node fulfills the installation requirements.

    • Install Argo CD.

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

      Allow some time for the deployment of Argo CD components in the argocd namespace.

Use this script to check the Longhorn environment for potential issues.

Installing Longhorn

  1. Log in to Argo CD.

    argocd login --core
    
  2. Set the current namespace to argocd.

    kubectl config set-context --current --namespace=argocd
    
  3. Create the Longhorn Application custom resource.

    cat > longhorn-application.yaml <<EOF
    apiVersion: argoproj.io/v1alpha1
    kind: Application
    metadata:
      name: longhorn
      namespace: argocd
    spec:
      project: default
      sources:
        - chart: longhorn
          repoURL: https://charts.longhorn.io/
          targetRevision: v1.6.0 # Replace with the Longhorn version you'd like to install or upgrade to
          helm:
            values: |
              preUpgradeChecker:
                jobEnabled: false
      destination:
        server: https://kubernetes.default.svc
        namespace: longhorn-system
    EOF
    kubectl apply -f longhorn-application.yaml
    
  4. Deploy Longhorn with the configured settings.

    argocd app sync longhorn
    
  5. Verify that Longhorn was installed successfully.

    kubectl -n longhorn-system get pod
