Install Portworx with a custom container registry on bare metal
Follow the instructions on this page to deploy Portworx and its required packages on a bare metal Kubernetes cluster using a custom container registry.
The steps in this document use the air-gapped-install bootstrap script to create a custom registry for internet connected clusters. If you're looking for install instructions for air-gapped clusters, refer to the air-gapped installation section.
Prerequisites
- You must have a Kubernetes cluster deployed on infrastructure that meets the minimum requirements for Portworx.
- You must attach backing storage disks to each worker node.
- You must have dedicated metadata disks attached to the worker nodes.
- The same KVDB device should be present on at least 3 of your nodes, and it should have the same unique device name across all the KVDB nodes.
Configure your custom registry
-
Set an environment variable for the Kubernetes version that you are using:
KBVER=$(kubectl version --short | awk -F'[v+_-]' '/Server Version: / {print $3}') -
Set an environment variable to the latest major version of Portworx:
PXVER=<portworx-version> -
On an internet-connected host with the same architecture and OS version as the Kubernetes cluster nodes intended for Portworx installation, download the air-gapped installation bootstrap script for the specified Kubernetes and Portworx versions:
curl -o px-ag-install.sh -L "https://install.portworx.com/$PXVER/air-gapped?kbver=$KBVER" -
Pull the container images required for the specified versions:
sh px-ag-install.sh pull -
Log in to docker:
docker login <your-custom-registry> -
Push the container images to a custom registry that is accessible to your nodes. Do not include
http://in your custom registry path:sh px-ag-install.sh push <your-registry-path>For example:
sh px-ag-install.sh push myregistry.net:5443Example for pushing image to a specific repo:
sh px-ag-install.sh push myregistry.net:5443/px-images
Create a version manifest configmap for the Portworx Operator
-
Download the Portworx version manifest:
curl -o versions.yaml "https://install.portworx.com/$PXVER/version?kbver=$KBVER" -
(Optional) If your installation images are spread across multiple custom registries, update your version manifest with the custom registry location details. You can use DNS hostname+domain or IP addresses (IPv4 or IPv6) to specify the container registry server in the following format:
<dns-host.domain or IPv4 or IPv6>[:<port>]/repository/image:tagThe following example demonstrates registries using a custom DNS hostname + domain, IPv4, and IPv6:
version: 2.13.3
components:
stork: custom-registry.acme.org/portworx/backup/stork:23.2.1
autopilot: 192.168.1.2:5433/tools/autopilot:1.3.7
nodeWiper: [2001:db8:3333:4444:5555:6666:7777:8888]:5443/portworx/px-node-wiper:2.13.2note-
Ensure that the Custom Container Registry location field is empty for any specs you generate in the spec generator.
-
kubeScheduler,kubeControllerManager, andpausemay not appear in the version manifest, but you can include them in thepx-versionconfigmap:
...
kubeScheduler: custom-registry.acme.org/k8s/kube-scheduler-amd64:v$KBVER
kubeControllerManager: custom-registry.acme.org/k8s/kube-controller-manager-amd64:v$KBVER
pause: custom-registry.acme.org/k8s/pause:3.1 -
-
Create a configmap from the downloaded or updated version manifest:
kubectl -n <px-namespace> create configmap px-versions --from-file=versions.yaml
Generate a Portworx spec
-
Navigate to Portworx Central and log in, or create an account.
-
Select Portworx Enterprise from the product catalog and click Continue.
-
On the Product Line page, choose any option depending on which license you intend to use, then click Continue.
-
For Platform, select DAS/SAN, then click Customize at the bottom of the Summary section.
-
On the Basic page, ensure that the Use the Portworx Operator and Built-in ETCD options are selected. For Portworx version, select the same value from the dropdown that you have set as your Portworx version in the Configure your environment section and click Next.
-
Keep the recommended default values for the Storage page and click Next
-
Choose your network options and click Next.
-
On the Customize page, select None for the Are you running on either of these? option. leave the Custom Container Registry Location blank in Registry And Image Settings. Select Finish to generate the specs.
Apply specs
Apply the Operator and StorageCluster specs you generated in the section above by performing the following steps:
-
Deploy the Operator:
kubectl apply -f 'https://install.portworx.com/<PXVER>?comp=pxoperator'serviceaccount/portworx-operator created
podsecuritypolicy.policy/px-operator created
clusterrole.rbac.authorization.k8s.io/portworx-operator created

Deploy the StorageCluster:
kubectl apply -f 'https://install.portworx.com/<PXVER>?operator=true&mc=false&kbver=&b=true&c=px-cluster-xxxxxxxx-xxxx-xxxx-xxxx-8dfd338e915b&stork=true&csi=true&mon=true&tel=false&st=k8s&promop=true'storagecluster.core.libopenstorage.org/px-cluster-xxxxxxxx-xxxx-xxxx-xxxx-8dfd338e915b created
Verify your Portworx installation
Once you've installed Portworx, you can perform the following tasks to verify that Portworx has installed correctly.
Verify if all pods are running
Enter the following kubectl get pods command to list and filter the results for Portworx pods:
kubectl get pods -n <px-namespace> -o wide | grep -e portworx -e px

Note the name of one of your px-cluster pods. You'll run pxctl commands from these pods in following steps.
Verify Portworx cluster status
You can find the status of the Portworx cluster by running pxctl status commands from a pod. Enter the following kubectl exec command, specifying the pod name you retrieved in the previous section:
kubectl exec <pod-name> -n <px-namespace> -- /opt/pwx/bin/pxctl status

Create your first PVC
For your apps to use persistent volumes powered by Portworx, you must use a StorageClass that references Portworx as the provisioner. Portworx includes a number of default StorageClasses, which you can reference with PersistentVolumeClaims (PVCs) you create. For a more general overview of how storage works within Kubernetes, refer to the Persistent Volumes section of the Kubernetes documentation.
Perform the following steps to create a PVC:
-
Create a PVC referencing the
px-csi-dbdefault StorageClass and save the file:kind: PersistentVolumeClaim
apiVersion: v1
metadata:
name: px-check-pvc
spec:
storageClassName: px-csi-db
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 2Gi -
Run the
kubectl applycommand to create a PVC:kubectl apply -f <your-pvc-name>.yamlpersistentvolumeclaim/px-check-pvc created
Verify your StorageClass and PVC
-

kubectl get storageclasscommand:kubectl get storageclassNAME PROVISIONER RECLAIMPOLICY VOLUMEBINDINGMODE ALLOWVOLUMEEXPANSION AGE
