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, unzip, and untar YAML_8.0.300.tar.gz , all files required for installation are available.

Note:

You must download images required for installation from the Veritas 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 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 assign a clusterrole to infoscale-admin. You must be logged in as a super user.

  1. kubectl config use-context kubernetes-admin@kubernetes

    You have switched the context to kubernetes-admin@kubernetes.

  2. kubectl apply -f /YAML/Kubernetes/infoscale-admin-role.yaml

    Here, infoscale-admin-role.yaml is downloaded as a part of YAML_8.0.300.tar.gz .

  3. kubectl create clusterrolebinding infoscale-admin-clusterrolebinding --clusterrole=infoscale-admin-role --user=infoscale-admin

    This step binds the cluster role infoscale-admin-role.yaml to a new user - infoscale-admin.

  4. openssl genrsa -out infoscale-admin.key 2048

    You have generated a key for infoscale-admin by using 2048 bits.

    openssl req -new -key infoscale-admin.key -out infoscale-admin.csr -subj "/CN=infoscale-admin"

    You have created a certificate signing request for infoscale-admin.

    openssl x509 -req -in infoscale-admin.csr -CA /etc/kubernetes/pki/ca.crt -CAkey /etc/kubernetes/pki/ca.key -CAcreateserial -out infoscale-admin.crt -days <Number of days>

    The certificate is signed by Kubernetes, a crt file is created, and is valid for the number of days you specified in the command.

  5. mkdir /certs && mv infoscale-admin.crt infoscale-admin.key /certs

    infoscale-admin.crt and infoscale-admin.key moved to /certs folder for the lico.yaml to reference.

  6. cd /certs

    kubectl config set-credentials infoscale-admin --client-certificate=/certs/infoscale-admin.crt --client-key=/certs/infoscale-admin.key

    kubectl config set-context infoscale-admin.context --cluster=kubernetes --user=infoscale-admin

    kubectl config use-context infoscale-admin.context

    Credentials are set for infoscale-admin and its context created.

  7. kubectl config current-context infoscale-admin.context

    Ensures that the current context is infoscale-admin.context.

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:8.0.300-<rhel8/ol8> with image: <IP address of custom registry>/infoscale-sds-operator:8.0.300-<rhel8/ol8>.

  2. Edit /YAML/Kubernetes/lico.yaml as under -

    Replace image: 192.168.1.21/veritas/infoscale-licensing-operator:8.0.300-ol8 with image: <IP address of custom registry>/infoscale-licensing-operator:8.0.300-<rhel8/ol8>.

  3. Edit /YAML/DR/Kubernetes/dro_deployment.yaml as under -

    Replace image: 192.168.1.21/veritas/infoscale-dr-manager:8.0.300-rhel8 with image: <IP address of custom registry>/veritas/infoscale-dr-manager:8.0.300-<rhel8/ol8>.

  4. Optionally, if you want to change the default kubelet path, edit /YAML/Kubernetes/iso.yaml as under.

    env:

   - name: KUBELET_PATH

     value: <enter the new path>

    The default path is /var/lib/kubelet.

    Note:

    Do not change the kubelet path after clusters are configured.

  5. Run the following command on the master node to install Veritas InfoScale.

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

  6. 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-6dc9bc8856-lh72f 1/1     Running 0        2d18h
