Install SMM with the SMM Operator chart

SMM Operator is a Kubernetes operator to deploy and manage Service Mesh Manager. In this chart the CRD is not managed by the operator, and we expect CI/CD tools to take care of updating CRD.

In case you have your own cluster deployed and are authorized to fetch images from the Cisco provided repositories, then you can rely on BasicAuth(url, username, password) for authentication required to pull images.

You can get a Username and Password by signing up for the Free tier version of Service Mesh Manager.

Prerequisites

Helm version 3.7 or newer.

Steps

  1. Create two namespaces, one for smm-operator (called smm-registry-access), and one for cert-manager:

    kubectl create ns smm-registry-access
    kubectl create ns cert-manager
    
  2. Run the following helm commands. Replace <your-username> and <your-password> with the ones shown on your Service Mesh Manager download page.

    export HELM_EXPERIMENTAL_OCI=1
    echo <your-password> | helm registry login registry.eticloud.io -u '<your-username>' --password-stdin
    
    helm pull oci://registry.eticloud.io/smm-charts/smm-operator --version <smm-version>
    
    helm install \
      --namespace=smm-registry-access \
      --set "global.ecr.enabled=false" \
      --set "global.basicAuth.username=<your-username>" \
      --set "global.basicAuth.password=<your-password>" \
      smm-operator \
      oci://registry.eticloud.io/smm-charts/smm-operator --version <smm-version>
    
  3. Install Service Mesh Manager by creating a ControlPlane resource. We recommend that you start with the following ControlPlane resource. This CR assumes that you are using docker-registry authentication, and the secrets referenced in the .spec.registryAccess is used to pull smm-operator image and sync across other namespaces created by the smm-operator chart.

    kubectl apply -f - << EOF

        sre:
          enabled: true
        useIstioResources: true
    EOF
    

Note: When installing SMM on a Kind cluster, the clusterName is not recognized automatically. In this case, specify the name of the cluster in the controlPlane resource:

spec:
  clusterName: <cluster-name>

The cluster name format must comply with the RFC 1123 DNS subdomain/label format (alphanumeric string without “_” or “.” characters).

Uninstalling the chart

To uninstall/delete the ControlPlane resource and smm-operator release, run:

kubectl delete controlplanes.smm.cisco.com smm
helm uninstall --namespace=smm-registry-access smm-operator
