docker-debian8-ansible's Introduction

Debian 8 (Jessie) Ansible Test Image

Debian 8 (Jessie) Docker container for Ansible playbook and role testing.

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:

Install Docker.
cd into this directory.
Run docker build -t debian8-ansible .

Note: Switch between master and testing depending on whether you want the extra testing tools present in the resulting image.

How to Use

Install Docker.
Pull this image from Docker Hub: docker pull geerlingguy/docker-debian8-ansible:latest (or use the image you built earlier, e.g. debian8-ansible).
Run a container from the image: docker run --detach --privileged --volume=/sys/fs/cgroup:/sys/fs/cgroup:ro geerlingguy/docker-debian8-ansible:latest /lib/systemd/systemd (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).
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!

Debian8 command error

I beg your pardon, but when I try to launch I have the error below.

$> docker run --detach --privileged --volume=/sys/fs/cgroup:/sys/fs/cgroup:ro geerlingguy/docker-debian8-ansible:latest /usr/lib/systemd/systemd

I am not sure, but I think you should correct /usr/lib/systemd/systemd into /lib/systemd/systemd.

I can reproduce the error locally and when run via the Docker Hub automated image build.

Archive this repository by June 30, 2020

In less than a month, Debian 8 'Jessie' LTS will no longer be actively maintained. Therefore I would like to deprecate and archive this repo and docker image, since I just started getting Python 2-related build failures and it's not worth the effort to get everything upgraded (and break half the world that uses this image) for less than a month's usage.

Can't install libssl-dev on this Docker image

See details here: gplessis/dotdeb-php#146

Basically, the following works (from the official Debian image):

docker pull debian:jessie
docker run --detach --privileged --volume=/sys/fs/cgroup:/sys/fs/cgroup:ro debian:jessie /lib/systemd/systemd
docker exec --tty [id] env TERM=xterm apt-get -y update
docker exec --tty [id] env TERM=xterm apt-get -y install libssl-dev

While the following doesn't (using this Docker image):

docker pull geerlingguy/docker-debian8-ansible:latest
docker run --detach --privileged --volume=/sys/fs/cgroup:/sys/fs/cgroup:ro geerlingguy/docker-debian8-ansible:latest /lib/systemd/systemd
docker exec --tty [id] env TERM=xterm apt-get -y update
docker exec --tty [id] env TERM=xterm apt-get -y install libssl-dev

The latter results in:

$ docker exec --tty 3c808f66 env TERM=xterm apt-get -y install libssl-dev

apt-get update fails

apt-get update fails, as there seems to be an issue with the source file.

This seems to solve the issue: https://superuser.com/questions/1423486/issue-with-fetching-http-deb-debian-org-debian-dists-jessie-updates-inrelease

W: Failed to fetch http://deb.debian.org/debian/dists/jessie-updates/InRelease  Unable to find expected entry 'main/binary-amd64/Packages' in Release file (Wrong sources.list entry or malformed file)

E: Some index files failed to download. They have been ignored, or old ones used instead.

Maintain 'testing' branch with test tools pre-installed

See: geerlingguy/docker-ubuntu1804-ansible#4

Basically, maintain latest as-is, but add a testing branch which includes Ansible plus:

yamllint
ansible-lint
flake8
testinfra
molecule

Ansible command and playbooks result in cryptography warning

Whenever I run Ansible commands I get:

[WARNING]: Optional dependency 'cryptography' raised an exception, falling back to 'Crypto'

No functional issue, just annoying. It looks like it's because of: ansible/ansible#13075 and ansible/ansible#16790

I can fix with a pip install of cryptography.
