Install the PX OCI Bundle on node01

First, SSH to node01:

ssh to node01 ssh -o strictHostKeyChecking=no node01

Make use of the latest stable image: latest_stable=$(curl -fsSL "https://install.portworx.com/?type=dock&stork=false" | awk '/image: / {print $2}')

echo $latest_stable

Using the latest stable release, let's install the bundle using the reference link below:

Install PX OCI Bundle

You can check the above link for more information or to confirm the command.

sudo docker run --entrypoint /runc-entry-point.sh --rm -i --privileged=true -v /opt/pwx:/opt/pwx -v /etc/pwx:/etc/pwx $latest_stable

Configure PX under runC on node01

Use the reference link below to configure px under runC. Make sure that you use the install flags for specifying the etcd and drives to be added the portworx cluster (Replace the ETCD HOST IP with the value from Step 1):

Configure PX under runC

sudo /opt/pwx/bin/px-runc install -c portworx-cluster1 -k etcd://${ETCD HOST IP}:4001 -s /dev/vdb

Note: This step configures systemd to start PX runC. If successful, you should see a bunch of INFO messages related to the configuration.

Enable and start Portworx service on node01

Make use of systemctl to enable and start PX service

systemctl enable portworx systemctl start portworx

Note: Once the service is started, it can take a couple of minutes for Portworx to initalize. Use the below command to monitor the PX cluster status: pxctl status

The above command may intially say PX is not running on this host, wait a few minutes and it should come online. You can also check the status by running systemctl status portworx

You should see Status: PX is operational from pxctl status

Now that we have installed Portworx on node01, lets scale the cluster with additional nodes.

Repeat steps 2 to 4 on new nodesi (node02 and node03).

ssh to node02 ssh -o strictHostKeyChecking=no node02

ssh to node03 ssh -o strictHostKeyChecking=no node03

On each node, execute all the below commands

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

sudo docker run --entrypoint /runc-entry-point.sh --rm -i --privileged=true -v /opt/pwx:/opt/pwx -v /etc/pwx:/etc/pwx $latest_stable

sudo /opt/pwx/bin/px-runc install -c portworx-cluster1 -k etcd://${ETCD HOST IP}:4001 -s /dev/vdb

systemctl enable portworx

systemctl start portworx

Verify there are three nodes before moving one

pxctl status

Verify Installation

Run the command pxctl status from any one of the nodes (node01-node03) and make sure that all 3 nodes have been added as a storage node.
