Upgrade Portworx using a Nomad job

Upgrade Portworx with Nomad by editing the portworx.nomad file you used for initial deployment and updating the container version.

Perform the following steps to update to the latest Portworx version:

1. Modify the image key value in your portworx.nomad file, changing the version to the latest Portworx version, for example, 2.11.1:

   image = "portworx/oci-monitor:2.11.1"

2. Rerun the portworx.nomad file:

   nomad run portworx.nomad

Nomad will do a rolling upgrade, i.e., only one instance will be updated at a time, not causing an impact on any applications (assuming application are running with more than one volume replica).

During the upgrade, you may see two versions of Portworx since we are doing a rolling upgrade:
