Foreman docker plugin setup help



TL;DR I was able to solve the problem while writing but decided to post anyway to contribute to documentation
I successfully installed foreman_docker plugin and configured the docker API to listen on the network. In the containers tab, I can see the container that is curently running on my docker container host.

However, I can’t turn on containers from Foreman Web even though the UI responds with a confirmation. Indeed, even though I was able to create the container, it doesn’t show up when I issue docker container ls

upport@server1100:~$ docker container ls
CONTAINER ID        IMAGE                         COMMAND             CREATED             STATUS              PORTS                                                                                                                                                          NAMES

Expected outcome:
Newly created container should be turned on after clicking “Power On”

Foreman and plugin versions:
Foreman: 1.19.1

Other relevant data:
I only found one relevant post but that was about accessing Docker API on HTTPS

I used the following links to configure docker and foreman:

I discovered that even if I run a docker container on the docker host the container don’t appear in “docker ps”. With “docker ps -a” suddenly the containers appeared and with them more information why the werent visible (see status):

They were in Exited state!

Turned out, that I overlooked a checkbox that requires starting the container. Note: This is not included in the docs, they are out-dated!

Looks like indeed we are missing update documentation for Foreman Docker plugin version 4.1, would you like to contribute to it? The manual is on github at and pull requests are welcome!


Hi @tbrisker I’d love to contribute! Stay tuned for my pull request


Submitted the PR and also created a Redmine issue. Feel free to add comments.
