Shared content for GCP

note

Portworx gets its storage capacity from the block storage mounted in the nodes and aggregates the capacity across all the nodes. This way, it creates a global storage pool. In our example, Portworx uses Persistent Disks (PD) as that block storage, where Portworx adds PDs automatically as the Kubernetes scales-out and removes PDs as nodes exit the cluster or get replaced.

Generate the specs

To install Portworx with Kubernetes, you must first generate Kubernetes manifests that you will deploy in your cluster:

Navigate to Portworx Central and log in, or create an account, then follow the process to generate a spec.

note

If you're using a cloud provider, do not add volumes of different types when configuring storage devices for during spec generation. For example, do not add both GP2 and GP3 for AWS, standard and ssd for GCP, or Standard and Premium for Azure. This can cause performance issues and errors.

Apply specs

Apply the Operator and StorageCluster specs you generated in the section above using the kubectl apply command:

1. Deploy the Operator:

   kubectl apply -f 'https://install.portworx.com/<version-number>?comp=pxoperator'

   serviceaccount/portworx-operator created
   podsecuritypolicy.policy/px-operator created
   clusterrole.rbac.authorization.k8s.io/portworx-operator created
   clusterrolebinding.rbac.authorization.k8s.io/portworx-operator created
   deployment.apps/portworx-operator created

2. Deploy the StorageCluster:

   kubectl apply -f 'https://install.portworx.com/<version-number>?operator=true&mc=false&kbver=&b=true&kd=type%3Dgp2%2Csize%3D150&s=%22type%3Dgp2%2Csize%3D150%22&c=px-cluster-XXXX-XXXX&eks=true&stork=true&csi=true&mon=true&tel=false&st=k8s&e==AWS_ACCESS_KEY_ID%3XXXX%2CAWS_SECRET_ACCESS_KEY%3XXXX&promop=true'

   storagecluster.core.libopenstorage.org/px-cluster-xxxxxxxx-xxxx-xxxx-xxxx-8dfd338e915b created

Monitor the Portworx pods

1. Enter the following kubectl get command, waiting until all Portworx pods show as ready in the output:

   kubectl get pods -o wide -n <px-namespace> -l name=portworx

2. Enter the following kubectl describe command with the ID of one of your Portworx pods to show the current installation status for individual nodes:

   kubectl -n <px-namespace> describe pods <portworx-pod-id>

note

In your output, the image pulled will differ based on your chosen Portworx license type and version.

Monitor the cluster status

Use the pxctl status command to display the status of your Portworx cluster:

PX_POD=$(kubectl get pods -l name=portworx -n <px-namespace> -o jsonpath='{.items[0].metadata.name}')
kubectl exec $PX_POD -n <px-namespace> -- /opt/pwx/bin/pxctl status
