ansible server in a docker container

Ansible Server in a Docker Debian Container

--guide here https://docs.ansible.com/ansible/latest/installation_guide/intro_installation.html

Setup

Read over the docker_ansible_install.sh file and make changes accordingly. Using pip3 instead of Debian packages. Running that file will create the Dockerfile, its image and a docker-compose.yaml file. Don't forget to chmod +x the executable .sh files. The provided Dockerfile and docker-compose.yaml are examples.

Notes on curls and wgets

For wget (and maybe curl) to work, ca-certificates package needs to be installed. You may also need to destroy any external network you're using (along with containers that use it) and recreate the network setting the mtu to 1400~ish. Here's an example
docker network create \
--driver=bridge \
--subnet=172.16.0.0/26 \
--ip-range=172.16.0.0/27 \
--gateway=172.16.0.1 \
-o com.docker.network.driver.mtu=1400 \
<network_name>

Note on Alias Usage

Precede any scripts with a . before running any scripts that might rely on aliases. The best thing to do for production / permanent files would be functions though. Here is an example of using the "dot command" to make your environment accessible to scripts.
. ./your_script.sh

Example Usage

Your script ansible calls can look something like this (creating a role):
docker exec -it ansible_ansible_1 /bin/bash -c 'ansible-galaxy role init ~/.ansible/roles/kvm_provision'

Create an alias in ~/.bashrc or ad-hoc to run commands as if ansible were installed:

commands='ansible

ansible-connection
ansible-console
ansible-galaxy
ansible-inventory
ansible-playbook
ansible-pull
ansible-test
ansible-vault'

container_name='ansible'

for command in $commands; do 
	alias $command="docker exec -it "$container_name" ./"$command""$1""
done```  
```$ ansible --version```  
```ansible [core 2.13.0]
  config file = /etc/ansible/ansible.cfg
