Ubuntu 20.04 LTS (Focal Fossa) Ansible Test Image

Ubuntu 20.04 LTS (Focal Fossa) Docker container for Ansible playbook and role testing.

Tags

• latest: Latest stable version of Ansible.

The latest tag is a lightweight image for basic validation of Ansible playbooks.

How to Build

This image is built on Docker Hub automatically any time the upstream OS container is rebuilt, and any time a commit is made or merged to the master branch. But if you need to build the image on your own locally, do the following:

1. Install Docker.
2. cd into this directory.
3. Run docker build -t ubuntu2004-ansible .

How to Use

1. Install Docker.
2. Pull this image from Docker Hub: docker pull geerlingguy/docker-ubuntu2004-ansible:latest (or use the image you built earlier, e.g. ubuntu2004-ansible:latest).
3. Run a container from the image: docker run --detach --privileged --volume=/sys/fs/cgroup:/sys/fs/cgroup:rw --cgroupns=host geerlingguy/docker-ubuntu2004-ansible:latest (to test my Ansible roles, I add in a volume mounted from the current working directory with --volume=`pwd`:/etc/ansible/roles/role_under_test:ro).
4. Use Ansible inside the container: a. docker exec --tty [container_id] env TERM=xterm ansible --version b. docker exec --tty [container_id] env TERM=xterm ansible-playbook /path/to/ansible/playbook.yml --syntax-check

Notes

I use Docker to test my Ansible roles and playbooks on multiple OSes using CI tools like Jenkins and Travis. This container allows me to test roles and playbooks using Ansible running locally inside the container.

Important Note: I use this image for testing in an isolated environment—not for production—and the settings and configuration used may not be suitable for a secure and performant production environment. Use on production servers/in the wild at your own risk!

docker-ubuntu2004-ansible's Issues

Image build asking for geographic area and timezone if using Podman

Just tried building this image with rootless Podman and it asks for the area I live in and the timezone. I think it should build without asking questions.

Add "testing" tag with testing tools

Can you add a testing branch/tag like you have with docker-ubuntu1804-ansible? I'm looking to lint my playbooks on 20.04 instead of 18.04.

Image build now getting hung up at '

After merging #12, I'm now seeing in the image build pipeline:

Setting up tzdata (2021a-0ubuntu0.20.04) ...
debconf: unable to initialize frontend: Dialog
debconf: (TERM is not set, so the dialog frontend is not usable.)
debconf: falling back to frontend: Readline
Configuring tzdata
------------------

Please select the geographic area in which you live. Subsequent configuration
questions will narrow this down by presenting a list of cities, representing
the time zones in which they are located.

  1. Africa      4. Australia  7. Atlantic  10. Pacific  13. Etc
  2. America     5. Arctic     8. Europe    11. SystemV
  3. Antarctica  6. Asia       9. Indian    12. US

Question regarding Podman compatibility?

Hello
Would you accept a PR to make this image compatible with rootless podman?
I realized that your Debian 10 image works without issues but this one does not. Discussion is here

containers/podman#8545 (comment)

This issue is probably caused by the VOLUMES in this repo's Dockerfile.

libyaml support not being loaded when I install Ansible + pyyaml

I have recently updated the Dockerfile to install libyaml-devel, but it seems like Ansible might still be using Python-based yaml parsing, judging by lackluster performance (see ansible/ansible#72030), as well as the fact that python3 -c 'import _yaml' gives:

root@93e95ea9dc5a:/# python3 -c 'import _yaml'
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ModuleNotFoundError: No module named '_yaml'

LOAD   = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB    = The low-level unit activation state, values depend on unit type.

22 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'.

I have also tried setting DBUS_SESSION_BUS_ADDRESS: unix:path=/run/user/1000/bus for that task with environment, but it fails the same way. I then tried it again but with the whole environment as per the env command after su - ansible, and same error.

What I don't get is why is that command running directly in the container with su - ansible, but not in the task or with sudo -u ansible.

Project description link is wrong

It should be https://hub.docker.com/r/geerlingguy/docker-ubuntu2004-ansible

Unable to update apt cache

For some reason, I am unable to update the apt cache with this docker image.
I tried it with ubuntu:latest where everything works fine.
Do you have an idea how to solve this?

Service is in unknown state

Hey there,

I am quite new to Molecule and currently developing an Ansible Role to install Zabbix Agent on Ubuntu, Debian and CentOS.
After installation i want to ensure the service is up and running with the following task:

- name: Start Zabbix Agent service
  service:
    name: zabbix-agent
    state: started
  when:
    - ansible_os_family == 'RedHat' or
      ansible_os_family == 'Debian'

When running molecule converge the step fails for all three docker images and i can't figure out why.

fatal: [ubuntu]: FAILED! => {"changed": false, "msg": "Service is in unknown state", "status": {}}

The Agent is installed via .deb packages which are provided by Zabbix for each distribution. The error also occures when I try starting other services. So this shouldn't be a Zabbix related problem.

I also (try) to verify the service is running after applying the role with the following assertion in my verify.yml:

- name: Check if Zabbix Agent is running
  assert: 
    that: 'ansible_facts.services["zabbix-agent"].state == "started"'

...which currently is failing.

I did some research on Google and I looked at some of your Ansible Roles like ansible-role-nginx but can not locate my problem here. The nginx service is started exactly the same.
When inside the container i can start the service manually by running: service zabbix-agent start. When running this command through Ansible's command module, the service is also started, but i would rather use the existing systemd or service module of Ansible because the command will not work like this on CentOS.
Any ideas why it is not working? Do I have to adjust/extend the docker image?

This is probably an issue on my hand, but maybe you can point me into the right direction.

Thanks in advance!

apt install package (molecule testing)

New to molecule here. So guide me with anything I'm missing, please.

Expected behavior

APT installs nano, htop, and snapd

Missing pycairo

Trying to run the following:

ansible-test integration --requirements --docker geerlingguy/docker-ubuntu2004-ansible --python-interpreter /usr/bin/python3

Yields the following error:

>>> Standard Output
pygobject 3.36.0 requires pycairo, which is not installed.

Unable to find "gnupg" package

Hi Jeff,

Thank you for your great contribution.
Trying to use "geerlingguy.docker" ansible role in a playbook and written a molecule test scenario using this docker image as a test platform/image but the testing fails as follows:
TASK [geerlingguy.docker : Ensure additional dependencies are installed (on Ubuntu >= 20.04).] *** fatal: [instance]: FAILED! => {"changed": false, "msg": "No package matching 'gnupg' is available"}
when doing molecule login and run 'apt list gnupg' the package is not being listed.

Wrong echo command in Dockerfile

It should be "echo -e" to interpret the Newline escape in newer versions of bash. Right now the \n literal is written

# Install Ansible inventory file.
RUN mkdir -p /etc/ansible
RUN echo -e "[local]\nlocalhost ansible_connection=local" > /etc/ansible/hosts

Systemd not starting - Failed to connect to bus: No such file or directory

Hi everyone, I'm trying to test a role that installs postgresql using the docker driver for molecule but it seems that systemd is not starting.

Symptoms

• After postgres installation I get this log
• Systemctl commands do not connect to bus

root@ubuntu2004:/# systemctl show
Failed to connect to bus: No such file or directory
root@ubuntu2004:/# systemctl status
Failed to connect to bus: No such file or directory
root@ubuntu2004:/# systemctl status postgresql
Failed to connect to bus: No such file or directory

(this container has been created using molecule create && molecule login)
