Install on air-gapped environments

This topic explains how you can prepare your clusters in an air-gapped environment and install Portworx Backup on-premises.

Prepare air-gapped environments

If your cluster is internet-connected, skip this section. If your cluster is air-gapped, you must pull the following Docker images to either your docker registry, or your server:

• docker.io/portworx/pxcentral-onprem-api:2.6.0
• docker.io/portworx/pxcentral-onprem-ui-frontend:2.6.0
• docker.io/portworx/pxcentral-onprem-ui-backend:2.6.0
• docker.io/portworx/pxcentral-onprem-ui-lhbackend:2.6.0
• docker.io/portworx/pxcentral-onprem-post-setup:2.6.0
• docker.io/portworx/px-backup:2.6.0
• docker.io/portworx/postgresql:11.19.0-debian-11-r1
• docker.io/portworx/keycloak:21.1.1
• docker.io/portworx/keycloak-login-theme:2.2.0
• docker.io/portworx/busybox:1.31
• docker.io/portworx/mysql:5.7.41
• docker.io/portworx/mongodb:5.0.20-debian-11-r13
• docker.io/portworx/kopiaexecutor:1.2.9
• docker.io/portworx/nfsexecutor:1.2.9
• docker.io/portworx/filesystemctl:1.2.9

note

Refer to the Prepare air-gapped environment section to know more about the Stork and other openstorage images in your air-gapped environment, before installing Portworx Backup.

To pull the above Docker images and push them to an internal registry:

1. Download the pxcentral-ag-install-backup.sh air-gapped bootstrap Portworx Backup install script.

   curl -o pxcentral-ag-install-backup.sh -L "https://install.portworx.com/pxcentral-air-gapped?px-backup=true"

   You can also download the install script for a specific release by specifying a version query. For example:

   curl -o pxcentral-ag-install-backup.sh -L "https://install.portworx.com/pxcentral-air-gapped?version=2.6.0&px-backup=true"

2. Provide execute permission for the install script:

   chmod +x pxcentral-ag-install-backup.sh

3. Pull the container images using the pxcentral-ag-install-backup.sh script:

    ./pxcentral-ag-install-backup.sh pull

4. Push the images to a local registry server, accessible by the air-gapped nodes. Replace <repo> with your registry location.

   ./pxcentral-ag-install-backup.sh push <repo>

5. Generate the Portworx Backup installation spec (Helm command) from Portworx Central specgen.

   • Populate the values for backup version, namespace, helm option, environment, and StorageClass name.
   • Select Use custom registry, provide values for custom registry, image repository and image pull secret (create a secret only if image pulling from an internal repository requires credentials).
     

6. From the machine where you run the helm3 command:

   • Download the latest px-central package with the following command.

     curl -O https://raw.githubusercontent.com/portworx/helm/master/stable/px-central-2.6.0.tgz
   • Modify the Helm command generated from Step 2 to provide the helm package, instead of providing the repository. For example:

     helm install px-central portworx/px-central --namespace central --create-namespace --version 2.6.0 -f values-px-central.yaml

   Following is the modified command for air-gapped environment using the downloaded helm package:

   helm install px-central px-central-2.6.0.tgz --namespace central --create-namespace --version 2.6.0 -f values-px-central.yaml
