Install Portworx Universe on DC/OS for air-gapped clusters


This guide will help you install the Portworx Universe for DC/OS which contains the Portworx service as well as other services inlcuding Hadoop, Cassandra, Elastic Search, Kafka, etc which can utilize Portworx Volumes.

This guide is based on the DC/OS guide to install a local universe.

Download the pre-requisites

First you will need to download 3 files and transfer them to each of you DC/OS Master nodes

Install the services

On each of your Master nodes run the following steps:

Load the universe container into docker

The local universe could be a large file and may take few minutes to load.

docker load < local-universe.tar.gz

Copy the service files to /etc/systemd/system and start the services

sudo mv dcos-local-px-universe-registry.service /etc/systemd/system/
sudo mv dcos-local-px-universe-http.service /etc/systemd/system/
sudo systemctl daemon-reload
sudo systemctl enable dcos-local-px-universe-http
sudo systemctl enable dcos-local-px-universe-registry
sudo systemctl start dcos-local-px-universe-http
sudo systemctl start dcos-local-px-universe-registry

Confirm that the services are up

sudo systemctl status dcos-local-px-universe-http
sudo systemctl status dcos-local-px-universe-registry

Add the Portworx Universe to DC/OS

Run the dcos command to add the newly deployed universe to your DC/OS cluster

dcos package repo add local-universe http://master.mesos:8083/repo --index=0

Add the docker registry as a trusted store on each agent

On each agent node you will need to download the certificate from the newly deployed Docker registry to set is as trusted. To do this, run the following command on each agent node, including public agents.

sudo mkdir -p /etc/docker/certs.d/master.mesos:5001
sudo curl -o /etc/docker/certs.d/master.mesos:5001/ca.crt http://master.mesos:8083/certs/domain.crt
sudo systemctl restart docker
sudo mkdir /var/lib/dcos/pki/tls/certs # Only required on private agents
sudo cp /etc/docker/certs.d/master.mesos:5001/ca.crt /var/lib/dcos/pki/tls/certs/px-docker-registry-ca.crt
hash=$(openssl x509 -hash -noout -in /var/lib/dcos/pki/tls/certs/px-docker-registry-ca.crt)
sudo ln -s /var/lib/dcos/pki/tls/certs/px-docker-registry-ca.crt /var/lib/dcos/pki/tls/certs/${hash}.0

Verify local Universe available from DC/OS

To verify that the local Universe has been configured successfully, log in to the DC/OS UI and look at Catalog to see if the packages are available.

Using docker images from local registry

If you want to use any images from the newly deployed registry, you will need to update the image names to point to it when starting the services. For example, if the original Portworx docker image was portworx/px-enterprise:<tag>, you would use master.mesos:5001/portworx/px-enterprise:<tag>
