Build and Run an Ansible Execution Environment - ansible-builder and ansible-runner tools
How to build and run a custom "my_ee" Ansible Execution Environment specifying some custom System (git), Python (boto), and collection (community.aws) dependencies using the ansible-builder and ansible-runner toolset.


How to build and Run an Ansible Execution Environment?
Using an Ansible Execution Environment is the latest technology to maintain up-to-date Python dependency of the Ansible collections without interfering with your Linux system. It’s the evolution of Python Virtual Environment. This initial configuration sometimes is a roadblock for some Ansible users. I’m Luca Berton and welcome to today’s episode of Ansible Pilot.

Let’s talk about the Ansible Execution Environment.
The Ansible Execution Environment is a container image that can be utilized as Ansible control nodes.
It’s the latest technology developed by Red Hat to simplify the automation process.
The main advantage is a common environment for Development and Production images using container technology creating portable automation runtimes.
This technology superseded manual Python Virtual Environments, Ansible module dependencies, and bubblewrap.
Experienced users are probably familiar with a lot of challenges managing custom Python Virtual Environments and Ansible module dependencies. Enterprise users of Ansible Automation Platform were familiar limited to executing jobs under bubblewrap in order to isolate processes
The creation is performed by the Ansible Builder tool.
Ansible Builder produces a directory that acts as the build context for the container image build, containing the Containerfile
, along with any other files that need to be added to the image.
The execution is performed by the Ansible Runner tool.
The Ansible Runner enables you to run the Execution Environment as a container in the current machine. It is basically taking care that the content runs as expected.

How to Build an Ansible Execution Environment using ansible-builder tool.
I’m going to show you how to Build a custom “my_ee” Ansible Execution Environment using the ansible-builder tool specifying some custom System, Python, and collection dependency.
For example, let’s build a custom Ansible Execution Environment named “my_ee” with System requirements git
, Python libraries boto3
and Amazon Collection community.aws
dependencies.
code
- execution-environment.yml
---
version: 1
dependencies:
galaxy: requirements.yml
python: requirements.txt
system: bindep.txt
additional_build_steps:
prepend: |
RUN pip3 install --upgrade pip setuptools
append:
- RUN ls -al /
- requirements.yml
---
collections:
- name: community.aws
requirements.txt
botocore>=1.18.0
boto3>=1.15.0
boto>=2.49.0
- bindep.txt
git [platform:rpm]
git [platform:dpkg]
execution
$ ansible-builder build -t my_ee -v 3
Running command:
podman build -f context/Containerfile -t my_ee context
Complete! The build context can be found at: /home/devops/ee/context
When the ansible-builder tool is not installed you should install it via DNF command using the ansible Automation Platform subscription::
[[email protected] ee]# dnf install ansible-builder
The tool needs access to the Red Hat Container Registry available with your Red Hat Ansible Automation subscription (username and password of Red Hat Portal).
$ podman login registry.redhat.io
A successful build produces the following context/Containerfile:
ARG EE_BASE_IMAGE=registry.redhat.io/ansible-automation-platform-22/ee-minimal-rhel8:latest
ARG EE_BUILDER_IMAGE=registry.redhat.io/ansible-automation-platform-22/ansible-builder-rhel8:latest
