Ansible-bender reaches 0.5.0
Exciting times! I just released ansible-bender-0.5.0.
This update contains a ton of new stuff. There is the one feature I am very proud of — configuring the build process by using Ansible variables. Apart from that, I did a lot of bug fixes and usability improvements.
So with 0.5.0, you may get accustomed to use playbooks like these:
---
- name: Demonstration of ansible-bender functionality
hosts: all
vars:
ansible_bender:
base_image: python:3-alpine
working_container:
volumes:
- '{{ playbook_dir }}:/src'
target_image:
name: a-very-nice-image
working_dir: /src
labels:
built-by: '{{ ansible_user }}'
environment:
FILE_TO_PROCESS: README.md
tasks:
- name: Run a sample command
command: 'ls -lha /src'
- name: Stat a file
stat:
path: "{{ lookup('env','FILE_TO_PROCESS') }}"
Just create the ansible_bender variable and set configuration and metadata of
the build process. No need to pass them via CLI.
Let’s give it a shot:
$ ansible-bender build ./simple-playbook.yaml

I can see "FILE_TO_PROCESS=README.md" and "built-by": "tt", all good.
