Prerequisites

Ensure that your Tanzu cluster meets the minimum requirements for Portworx.

Configure your environment

Follow the instructions in this section to configure your environment before installing Portworx.

Enable privileged containers and kubectl exec

Ensure that the following options are selected on all plans on the TKGi tile:

• Enable Privileged Containers
• Disable DenyEscalatingExec (this is useful for using kubectl exec to run pxctl commands)

Configure Bosh Director addon

Bosh Director ensures the upgrades to Portworx TKGI clusters are performed with minimal disruption to the cluster's availability and functionality.

In the process of stopping and upgrading instances within a TKGI cluster, Kubernetes add-on expects all sharedv4 volumes to be unmounted. Portworx add-on does the job of unmounting the sharedv4 volume. This will ensure zero downtime upgrades for Portworx TKGI cluster.

Perform these steps on any machine where you have access to the Bosh CLI.

Upload a Portworx release to your Bosh Director environment

1. Run the following command to clone the portworx-stop-bosh-release repositories:

   git clone https://github.com/portworx/portworx-stop-bosh-release.git
   cd portworx-stop-bosh-release

2. Create the Portworx release with a final version (in this example, version 2.0.0) using the Bosh CLI:

   mkdir src
   bosh create-release --final --version=2.0.0

3.  Upload the release to your Bosh Director environment (replace `director-environment` with your actual environment):
 ```bash
 bosh -e director-environment upload-release

Add the Addon to the Bosh Director

1. Get your current Bosh Director runtime config:

   bosh -e director-environment runtime-config

   • If this is empty, you can simply use the runtime config at runtime-configs/director-runtime-config.yaml.

   • If you already have an existing runtime config, add the release and addon in runtime-configs/director-runtime-config.yaml to your existing runtime config.

2. Once you have the runtime config file prepared, update it in the Director:

   bosh -e director-environment update-runtime-config runtime-configs/director-runtime-config.yaml

Apply the changes

After the runtime config is updated, perform the following steps:

1. Navigate to the Installation Dashboard of Tanzu Operations Mangager Interface
2. Click on Review Pending Changes and apply the changes.

caution

While reviewing the pending changes above, if you removed the selection for Upgrade all clusters errands option under Errands for the Tanzu Kubernetes Grid Integration Edition tile, run the following commands to reconfigure your addon:

bosh manifest -d <deployment-name> >./<deployment-name>-manifest.yaml
bosh -d <deployment-name> deploy ./<deployment-name>-manifest.yaml

For all necessary flags for this command, refer to the Deploy details in the Bosh documentation.
