Docker Images

We use a lot of docker images in Europa.

Finding Docker Images

To find Images for Impact on docker:

• https://registry.hub.docker.com/u/zenoss/impact-unstable/tags/manage/

• Use curl:

  curl -s -u <<YOUR DOCKER HUB USERNAME>>
  https://registry.hub.docker.com//v1/repositories/zenoss/impact-unstable/tags \
    | python -m json.tool \
    | sed -n 's/.*"name": "\([^"]*\)"/\1/p' \
    | tail -1
  

Downgrading Docker in ControlCenter

If you find yourself needing to down grade docker:

1. Stop all services:

   serviced service stop zenoss.core
   

2. Stop/Kill/Maim serviced:

   service serviced stop (if running Release Images)
   killall serviced && killall -9 serviced (Otherwise)
   

3. Stop Docker:

   service docker stop
   

4. Remove docker:

   sudo apt-get purge lxc-docker\*
   sudo apt-get purge docker
   

5. Install the new (or older) docker:

   sudo apt-get install lxc-docker-1.3.3
   

6. Restart Docker and Service:

   service docker start
   service serviced start (If running Release Images)
   zendev serviced >& /tmp/serviced.log & (Otherwise)
   

7. Start your Zenoss services if required
