Install PX-Backup on air-gapped environment
This topic explains how you can prepare your clusters in an air-gapped environment and install PX-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:2.2.3
- docker.io/portworx/pxcentral-onprem-ui-frontend:2.2.3
- docker.io/portworx/pxcentral-onprem-ui-backend:2.2.3
- docker.io/portworx/pxcentral-onprem-ui-lhbackend:2.2.3
- docker.io/portworx/pxcentral-onprem-post-setup:2.2.3
- docker.io/portworx/postgresql:11.16.0-debian-11-r5
- docker.io/portworx/keycloak:16.1.1
- docker.io/portworx/keycloak-login-theme:2.2.0
- docker.io/portworx/busybox:1.31
- docker.io/portworx/mysql:5.7.38
- docker.io/portworx/px-backup:2.2.3
- docker.io/portworx/mongodb:4.4.4-debian-10-r30
- portworx/kopiaexecutor:1.2.0
openstorage
images in your air-gapped environment, before installing PX-Backup.
To pull the above Docker images and push them to an internal registry:
Download the
pxcentral-ag-install-backup.sh
air-gapped bootstrap PX-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=2.2.3&px-backup=true"
Pull the container images using the
pxcentral-ag-install-backup.sh
script../pxcentral-ag-install-backup.sh pull
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>
Generate the px-backup installation spec (Helm command) from https://central.portworx.com/specGen/wizard. Select the Use custom registry button and provide the values for registry, repository, and image pull secret ( create a secret only if image pulling from an internal repository requires credentials).
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-2.2.3.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 2.2.3 -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-2.2.3.tgz --namespace central--create-namespace --version 2.2.3 -f values-px-central.yaml
After performing the above steps, refer to the Install PX-Backup section to install PX-Backup on-premises.
