Installing the Special Resource Operator

You must install a Special Resource Operator (SRO) first, before installing Arctera InfoScale™. After the SRO is installed on the system, InfoScale can be deployed.

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

  2. Untar YAML.tar.

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

  3. On a Kubernetes cluster -

    • Run kubectl create -f /YAML/Kubernetes/sro.yaml on the master node to install the Special Resource Operator (SRO) .

      Review output as under.

      namespace/openshift-special-resource-operator created
customresourcedefinition.apiextensions.k8s.io/
       specialresources.sro.openshift.io created

configmap/special-resource-lifecycle created

    • Run kubectl create -f /YAML/Kubernetes/sr.yaml on the master node to create Special Resource.

      Review output as under.

      specialresource.sro.openshift.io/special-resource-preamble created

  4. Run the following commands and review the output to verify whether SR creation and SRO installation is successful.

    • kubectl get SpecialResource

      Output similar to the following indicates a successful installation.

      NAME                        AGE
special-resource-preamble   2m24s

    • kubectl 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  1/1   Running 0        2m35s
       -66c8fc64b5-9wv6l

      Note:

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

    • kubectl 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
