Installing InfoScale on Kubernetes

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

Note:

You must download images required for installation from the Arctera Download Center and push those to the Custom registry.

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 master 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. kubectl create ns <New Project name>
    namespace/<New Project name>  created

    indicates that a new project is created.

  2. kubectl create rolebinding infoscale-admin --namespace=<New Project name> --clusterrole=admin --user=infoscale-admin

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

    rolebinding.rbac.authorization.k8s.io/infoscale-admin created
  3. kubectl apply -f /YAML/Kubernetes/infoscale-admin-role.yaml

    Following output indicates that a clusterrolebinding is created. 

    clusterrole.rbac.authorization.k8s.io/infoscale-admin-role created
  4. kubectl create clusterrolebinding infoscale-admin-role --clusterrole=infoscale-admin-role --user=infoscale-admin

    Following output indicates that a clusterrole created is associated with infoscale-admin by using a specified ClusterRoleBinding.

    clusterrolebinding.rbac.authorization.k8s.io/infoscale-admin-role created

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

  1. Edit /YAML/Kubernetes/iso.yaml as under -

    Replace image: 192.168.1.21/veritas/infoscale-sds-operator:8.0.100-ol8 with image: <IP address of custom registry>/infoscale-sds-operator:8.0.100-ol8.

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

    kubectl create -f /YAML/Kubernetes/iso.yaml

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

    kubectl 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-7fb7cd57c-rskms 1/1   Running 0        4d3h
