Installing by using YAML.tar

You must install a Special Resource Operator (SRO) first, before installing Arctera InfoScale™. After the SRO is installed, the system is enabled for installing Arctera InfoScale™.

  1. Download YAML.tar from the Arctera Download Center.

  2. Untar YAML.tar.

    After you untar YAML.tar, the folders /YAML/OpenShift/, /YAML/OpenShift/air-gapped-systems , /YAML/DR, and /YAML/Kubernetes are created. Each folder contains files required for installation.

Optionally, you can configure a new user - infoscale-admin, associated with a Role-based Access Control ( RBAC) clusterrole defined ininfoscale-admin-role.yaml, to deploy InfoScale and its dependent components. infoscale-admin as a user when configured has clusterwide access to only those resources needed to deploy InfoScale and its dependent components such as SRO/NFD/Cert Manager in the desired namespaces.

To provide a secure and isolated environment for InfoScale deployment and associated resources, the namespace associated with these resources must be protected from access of all other users (except super user of the cluster), with appropriate RBAC implemented.

Run the following commands on the bastion node to create a new user - infoscale-admin and a new project and assign role or clusterrole to infoscale-admin. You must be logged in as a super user.

  1. oc new-project <New Project name>

    A new project is created for InfoScale deployment.

  2. oc adm policy add-role-to-user admin infoscale-admin

    Following output indicates that administrator privileges are assigned to the new user - infoscale-admin within the new project.

    clusterrole.rbac.authorization.k8s.io/admin added: "infoscale-admin"
  3. oc apply -f /YAML/OpenShift/infoscale-admin-role.yaml

    Following output indicates that a clusterrole is created.

    clusterrole.rbac.authorization.k8s.io/infoscale-admin-role created
  4. oc adm policy add-cluster-role-to-user infoscale-admin-role infoscale-admin

    Following output indicates that a clusterrole created is associated with infoscale-admin.

    clusterrole.rbac.authorization.k8s.io/infoscale-admin-role added:
              "infoscale-admin"
    

You must now perform all installation-related activities by logging in as infoscale-admin. A cluster super-user can also install InfoScale.

  1. Run the following commands on the bastion node to install -

    • Run oc create -f /YAML/OpenShift/sro.yaml on the bastion node to install the Special Resource Operator (SRO) .

    • Run oc create -f /YAML/OpenShift/sr.yaml on the bastion node to create Special Resource.

  2. Run the following commands on the bastion node and review the output to verify whether SR creation and SRO installation is successful.

    • oc get pods -n openshift-special-resource-operator

      Output similar to the following indicates a successful installation.

      NAME                                READY  STATUS    RESTARTS   AGE
      special-resource-controller-manager-66c8fc64b5-9wv6l 1/1  Running 0       2m35s
      

      Note:

      The name in the output here is used in the following command.

    • oc logs special-resource-controller-manager-66c8fc64b5-9wv6l -n openshift-special-resource-operator -c manager

      Output similar to the following indicates a successful installation.

      <timestamp>    INFO    status         
       RECONCILE SUCCESS: Reconcile
    • oc get SpecialResource

      Output similar to the following indicates a successful installation.

      NAME                        AGE
      special-resource-preamble   2m24s
      

As your system is connected with the Internet, you must login to the Red Hat registry before you install InfoScale. All information about the worker nodes must be added to the cr.yaml file. All worker nodes become part of InfoScale cluster after cr.yaml is applied.

Note:

After you download and untar YAML.tar, all files required for installation are available.

Applying Licenses

  1. Run oc create -f /YAML/OpenShift/lico.yaml on the bastion node.
  2. Run oc get pods -n infoscale-vtas|grep -i licensing on the bastion node to verify whether lico.yaml is successfully applied.

    An output similar to the following indicates that lico.yaml is successfully applied.

    NAME                                  READY STATUS  RESTARTS AGE
    licensing-operator-fbd8c7dc4-rcfz5    1/1   Running 0        2m
    
    
  3. After lico.yaml is successfully applied, licensing endpoints must be available.

    Run oc describe service/lico-webhook-service -n infoscale-vtas|grep Endpoints on the master node and review the output.

  4. Run the command again till you get an output in the following format.
    Endpoints: <IP address of the endpoint>:<Port number>
  5. Edit /YAML/OpenShift/license_cr.yaml for the license edition. The default license edition is Developer. You can change the licenseEdition. If you want to configure Disaster Recovery (DR), you must have Trialware or SubscriptionEnterprise as the license edition.
    apiVersion: vlic.veritas.com/v1
    kind: License
    metadata:
      name: license-dev
    spec:
      # valid licenseEdition values are Developer, Trialware, 
                 SubscriptionStorage or SubscriptionEnterprise
      licenseEdition: "Developer"
    
  6. Run oc create -f /YAML/OpenShift/license_cr.yaml on the bastion node.
  7. Run oc get licenses on the bastion node to verify whether licenses have been successfully applied.

    An output similar to the following indicates that license_cr.yaml is successfully applied.

    NAME          NAMESPACE   LICENSE-EDITION   AGE
    license                   DEVELOPER         27s
    
    

Complete the following steps to install iso.yaml.

  1. Run the following command on all the worker nodes.

    podman login registry.connect.redhat.com Username: {REGISTRY-SERVICE-ACCOUNT-USERNAME} Password: {REGISTRY-SERVICE-ACCOUNT-PASSWORD}

    Wait for the message - Login successful.

  2. Run the following command on the bastion node to install Arctera InfoScale™.

    oc create -f /YAML/OpenShift/iso.yaml

  3. Run the following command on the bastion node to verify whether the installation is successful

    oc get pods -n infoscale-vtas|grep infoscale-sds-operator

    An output similar to the following indicates a successful installation. READY 1/1 indicates that Storage cluster resources can be created.

    NAME                                   READY STATUS  RESTARTS AGE  
    infoscale-sds-operator-bb55cfc4d-pclt5 1/1   Running 0        20h
