Ansible Execution Environment

Ansible Execution Environment

Ansible EE and builder overview

An automation execution environment is a container image used to execute Ansible playbooks and roles. It provides a defined, consistent, portable environment for executing automation.

Ansible Builder was developed to automate the process of building Execution Environments. It does this by using the dependency information defined in various Ansible Content Collections, as well as by the user. Ansible Builder will produce a directory that acts as the build context for the container image build, which will contain the Containerfile, along with any other files that need to be added to the image.

Ansible Execution Environment for arista.cvp

Repository provides 2 different Execution environment definition:

  • Execution Environment to execute stable version of CV Collection
  • Execution Environment to execute development version of CV collection

Info

Even if CV collection provides such image, Execution Environments should be defined per ansible project and CV images only for testing. Indeed, our images are built with only our own requirements that can differ from your global project.

Build your runner for stable version

By default, ansible-builder uses podman to build image, if you want to use docker instead, add --container-runtime docker to your CLI

# clone repository
git clone https://github.com/aristanetworks/ansible-cvp.git

# Move to root of the repo
cd ansible-cvp

# Build image
$ ansible-builder build --tag <your-image-tag> -f ansible_collections/arista/cvp/meta/execution-environment.yml
Running command:
  podman build -f context/Containerfile -t inetsix/ansible-ee-avd:devel context
Complete! The build context can be found at: /Users/tgrimonet/Projects/avd-stack/ansible-cvp/context

# Validate collection is installed
## PODMAN method
podman container run -it --rm inetsix/ansible-ee-avd:pr ansible-galaxy collection list

## Docker method
docker run -it --rm inetsix/ansible-ee-avd:pr ansible-galaxy collection list
