Run Portworx with Mesosphere DC/OS

This document presents the non-Kubernetes method of installing Portworx with Mesosphere DC/OS. Please refer to the Run Portworx with Kubernetes on Mesosphere DC/OS page if you want to install Portworx with Kubernetes on Mesosphere DC/OS.

This DCOS service will deploy Portworx as well as all the dependencies and additional services to manage the Portworx cluster. This includes a highly available etcd cluster.

Portworx can be used to provision volumes on DCOS using either the Docker Volume Driver Interface (DVDI) or, directly through CSI.

Please ensure that your mesos private agents have unmounted block devices that can be used by Portworx.

(Optional) Deploy an AWS Portworx-ready cluster

Using this AWS CloudFormation template, you can easily deploy a DCOS 1.10 cluster that is “Portworx-ready”.

Pre-install (only required if moving from a Portworx Docker installation)

If you are moving from a Docker install of Portworx to an OCI install, please make sure that the Portworx service is stopped on all the agents before updating to the OCI install. To do this run the following command on all your private agents:

sudo systemctl stop portworx

Deploy Portworx

The Portworx service is available in the DCOS universe, you can find it by typing the name in the search bar.

Portworx in DCOS Universe

To modify the defaults, click on the Review & Run button next to the package on the DCOS UI.

On the Edit configuration page you can change the default configuration for Portworx deployment. Here you can choose to enable etcd (if you do not have an external etcd service). To have a custom etcd installation please refer to this doc.

Portworx Options

Specify your kvdb (consul or etcd) server if you don’t want to use the etcd cluster with this service. If the etcd cluster is enabled this config value will be ignored.

Note:
If you are trying to use block devices that already have a filesystem on them, either add the -f option to portworx options to force Portworx to use these disks or wipe the filesystem using wipefs command before installing.

Note:
For a full list of installation options, please look here.

Secrets Options

To use DC/OS secrets for Volume Encryption and storing Cloud Credentials, refer Portworx with DC/OS Secrets.

Etcd Options

By default a 3 node etcd cluster will be created with 5GB of local persistent storage. The size of the persistent disks can be changed during install. This can not be updated once the service has been started so please make sure you have enough storage resources available in your DCOS cluster before starting the install.

Install Status

Once you have started the install you can go to the Services page to monitor the status of the installation.

If you click on the portworx service you should be able to look at the status of the tasks being created. If you have enabled etcd, there will be 1 task for the framework scheduler and 3 tasks for etcd. Apart from these there will be one task on every node where Portworx runs.

Scaling Up Portworx Nodes

If you add more agents to your DCOS cluster and you want to install Portworx on those new nodes, you can increase the node count to start install on the new nodes. This will relaunch the service scheduler and install Portworx on the nodes which didn’t have it previously.

Install DCOS Portworx CLI

To install the dcos portworx CLI, run the following DCOS CLI command:

dcos package install portworx --cli
