Install SUSE® Storage Using 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.

Installation

  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:
       syncPolicy:
         syncOptions:
           - CreateNamespace=true
       project: default
       sources:
         - chart: longhorn
           repoURL: https://charts.longhorn.io/
           targetRevision: v1.7.0 # 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
