Onboard an AKS cluster directly

az aks enable-addons --resource-group rg-aks-primary --name aks-primary-cluster --addons gitops
az k8s-configuration create \
    --name aks-primary-cluster --resource-group rg-aks-primary --cluster-name aks-primary-cluster \
    --operator-instance-name global-configuration \
    --operator-namespace azure-gitops \
    --repository-url https://github.com/dexmach/k8sarc \
    --scope cluster \
    --cluster-type managedClusters \
    --operator-params "--git-poll-interval 10s --git-readonly --git-path=operations/aks-azure,operations/common --git-branch main" \
    --enable-helm-operator --helm-operator-chart-version='1.4.0' --helm-operator-params='--set helm.versions=v3'

edge clusters (arc onboarded)

az k8s-configuration create \
    --name edge-hardware-02 --resource-group rg-aks-arc --cluster-name edge-hardware-02 \
    --operator-instance-name global-configuration \
    --operator-namespace azure-gitops \
    --repository-url https://github.com/dexmach/k8sarc \
    --scope cluster \
    --cluster-type connectedClusters \
    --operator-params "--git-poll-interval 10s --git-readonly --git-path=operations/aks-edge,operations/common --git-branch main" \
    --enable-helm-operator --helm-operator-chart-version='1.4.0' --helm-operator-params='--set helm.versions=v3'

onboard the sample app

az k8s-configuration create \
    --name sample-app-config --resource-group rg-aks-primary --cluster-name aks-primary-cluster \
    --operator-instance-name sample-app-config \
    --operator-namespace demo \
    --repository-url https://github.com/dexmach/k8sarc \
    --scope namespace \
    --cluster-type managedClusters \
    --operator-params "--git-poll-interval 10s --git-readonly --git-path=sample-app-repo/deploy --git-branch main"

az k8s-configuration create \
    --name sample-app-config --resource-group rg-aks-arc --cluster-name edge-hardware-02 \

    --operator-namespace demo \
    --repository-url https://github.com/dexmach/k8sarc \
    --scope namespace \
