In this article, we'll focus on the building part. - -If you are familiar with Ansible, you know that you can write a series of tasks, and the **ansible-playbook** command will execute them for you. Did you know that you can also execute such commands in a container environment and get the same result as if you'd written a Dockerfile and run **podman build**. - -Here is an example: - - -``` -\- name: Serve our file using httpd -  hosts: all -  tasks: -  - name: Install httpd -    package: -      name: httpd -      state: installed -  - name: Copy our file to httpd’s webroot -    copy: -      src: our-file.txt -      dest: /var/www/html/ -``` - -You could execute this playbook locally on your web server or in a container, and it would work—as long as you remember to create the **our-file.txt** file first. - -But something is missing. You need to start (and configure) httpd in order for your file to be served. This is a difference between container builds and infrastructure provisioning: When building an image, you just prepare the content; running the container is a different task. On the other hand, you can attach metadata to the container image that tells the command to run by default. - -Here's where a tool would help. How about trying **ansible-bender**? - - -``` -`$ ansible-bender build the-playbook.yaml fedora:30 our-httpd` -``` - -This script uses the ansible-bender tool to execute the playbook against a Fedora 30 container image and names the resulting container image **our-httpd**. - -But when you run that container, it won't start httpd because it doesn't know how to do it.
