Upgrade the Portworx OCI bundle

Portworx provides a Docker-based installation utility to help deploy the Portworx OCI bundle. You can re-install this bundle by running the following Docker container on your host system:

REL="/3.0"  # Portworx v3.0 release

latest_stable=$(curl -fsSL "https://install.portworx.com$REL/?type=dock&stork=false&aut=false" | awk '/image: / {print $2}' | head -1)

# Download OCI bits (reminder, you will still need to run `px-runc install ..` after this step)
sudo docker run --entrypoint /runc-entry-point.sh \
    --rm -i --privileged=true \
    -v /opt/pwx:/opt/pwx -v /etc/pwx:/etc/pwx \
    $latest_stable

The following commands upgrade your Portworx OCI bundle to the latest stable:

latest_stable=$(curl -fsSL "https://install.portworx.com?type=dock&stork=false&aut=false" | awk '/image: / {print $2}' | head -1)
sudo docker run --entrypoint /runc-entry-point.sh \
    --rm -i --privileged=true \
    -v /opt/pwx:/opt/pwx -v /etc/pwx:/etc/pwx \
    $latest_stable --upgrade
sudo systemctl restart portworx

Once the update process is finished, you must restart the Portworx service.

note

If you are installing Portworx on RedHat Linux or RedHat CoreOS with CRI-O container runtime, you don't have to install Docker in order to install Portworx. Instead, simply replace docker command with podman (e.g. sudo podman run --entrypoint...).

Uninstall the Portworx OCI bundle

Run the following commands to uninstall the Portworx OCI bundle:

# 1: Remove systemd service (if any)
sudo systemctl stop portworx
sudo systemctl disable portworx
sudo rm -f /etc/systemd/system/portworx*

# NOTE: if the steps below fail, please reboot the node, and repeat the steps 2..5

# 2: Unmount oci (if required)
grep -q '/opt/pwx/oci /opt/pwx/oci' /proc/self/mountinfo && sudo umount /opt/pwx/oci

# 3: Remove binary files
sudo rm -fr /opt/pwx

# 4: [OPTIONAL] Remove configuration files. Doing this means UNRECOVERABLE DATA LOSS.
sudo chattr -ie /etc/pwx/.private.json
sudo rm -fr /etc/pwx
