Overview

Sample scripts to deploy PostgreSQL to Mesosphere DC/OS with Local Persistent Storage enabled.

Steps

** Replace kojiha/postgres_test with your own tag.

(1) build a container image

docker build -t kojiha/postgres_test .

(2) push the image to your container registry

docker login
docker push kojiha/postgres_test

(3) modify marathon.json for your environment

Customization points are:

• docker.image
• container.volumes.containerPath and env.PGDATA
• container.volumes.persistent.size
• add POSTGRES_USER, POSTGRES_PASSWORD in env as you need

At least you must modify docker.image for your image location.

(4) deploy the image to DC/OS via marathon

dcos marathon app add marathon.json

or put the marathon.json content into JSON CONFIGUFATION text area of DC/OS 'Run a Service' UI.

(5) verify if the service is running with a volume attached

Comments

• container.volumes.containerPath may not contain any slashes

• The environment variable PGDATA must have a path /mnt/mesos/sandbox/ + the value set in container.volumes.containerPath
