Setup Apache Web Server in a Docker Container for Debian-like systems
- install packages =>
ansible.builtin.apt - docker py module =>
ansible.builtin.pip - pull image =>
community.docker.docker_image - document root =>
ansible.builtin.file - custom index.html =>
ansible.builtin.copy - run container =>
community.docker.docker_container
Today we're talking about how to deploy a web server apache httpd in a Docker Container for Debian-like Linux systems.
The full process requires six steps that you could automate with different Ansible modules.
Firstly you need to install some python packages and dependencies using the ansible.builtin.apt Ansible module.
Secondly, you need to install the Docker Module for Python using the ansible.builtin.pip Ansible module.
Thirdly, you need to pull the image for the docker hub registry using the community.docker.docker_image Ansible module.
Fourthly, you need to create the document root with the right permission with the ansible.builtin.file module.
Fifty, you need to create the custom index.html with ansible.builtin.copy Ansible module. You could upgrade this step using the template module.
Finally, you could run the webserver container setting the right port and volume settings using the community.docker.docker_container Ansible module.
