Development Tips & Tricks¶
Two methods can be used to get Ansible up and running quickly with all the requirements to leverage ansible-avd: a Python Virtual Environment or a Docker container.
The best way to use the development files is to copy them to the root directory where you have your repositories cloned. For example, see the file/folder structure below.
├── git_projects │ ├── ansible-avd │ ├── ansible-cvp │ ├── netdevops-examples | ├── <YOUR OWN TESTING REPOSITORY> │ ├── Makefile
Build local environment¶
Please refer to Setup environment page
Once installed, use
dev-start command to bring up all the required containers:
- An mkdoc for AVD documentation listening on port
- An mkdoc or CVP documentation listening on port
- An AVD runner with a pseudo terminal connected to shell for Ansible execution
The Docker container approach for development can be used to ensure that everybody is using the same development environment while still being flexible enough to use the repository you are making changes to. You can inspect the Dockerfile to see what packages have been installed. The container will mount the current working directory so that you can work with your local files.
The Ansible version is passed in with the Docker build command using the
ANSIBLE_VERSION variable. If the variable isn’t defined, the Dockerfile will, by default, set the Ansible version to what’s specified in the AVD requirements.
Before you can use a container, you must install Docker CE and docker-compose on your workstation.
Since the AVD Docker image is now automatically published on docker-hub, a dedicated repository is available on Arista NetDevOps Community.

pre-commit can run standard hooks on every commit to automatically point out issues in code such as missing semicolons, trailing whitespace, and debug statements. Pointing these issues out before code review allows a code reviewer to focus on the architecture of a change while not wasting time with trivial style nitpicks.
Repository implements following hooks:
trailing-whitespace: Fix trailing whitespace. If found, commit is stopped, and you must rerun the commit process.
trailing-whitespace, this hook fixes the wrong end of the file and stops your commit.
check-yaml: Checks that all YAML files are valid.
check-added-large-files: Check if there is no large file included in the repository.
check-merge-conflict: Validate there is no
MERGEsyntax related to an invalid merge process.
pylint: Run python linting with settings defined in pylintrc.
yamllint: Validate all YAML files using configuration from yamllintrc.
ansible-lint: Validate YAML files with Ansible proven practices, patters, and behaviors.
Flake8: Style guide enforcement for Python code base.
markdownlint-cli: Validates markdown files for common errors as referenced here.
pre-commit is part of development requirements. To install, run
pip command in ansible-avd folder:
Run pre-commit manually¶
pre-commit manually before your commit, use this command:
pre-commit run [WARNING] Unstaged files detected. [INFO] Stashing unstaged files to /Users/xxx/.cache/pre-commit/patch1590742434. Trim Trailing Whitespace.............................(no files to check)Skipped Fix End of Files.....................................(no files to check)Skipped Check Yaml...........................................(no files to check)Skipped Check for added large files..........................(no files to check)Skipped Check for merge conflicts............................(no files to check)Skipped Check for Linting error on Python files..............(no files to check)Skipped Check for Linting error on YAML files................(no files to check)Skipped Check for ansible-lint errors............................................Passed [INFO] Restored changes from /Users/xxx/.cache/pre-commit/patch1590742434.
Command will automatically detect changed files using
git status and run tests according their type.
This process is also implemented in project CI to ensure code quality and compliance with Ansible development process.
Configure Git hook¶
To automatically run tests when running a commit, configure your repository with the following command:
To remove installation, use
Check 404 links¶
To validate documentation, you should check for not found links in your local version of the documentation. This test requires to run mkdocs container as explained in installation documentation.
In a shell, run the following make command. It starts a container in the AVD documentation network and leverages
muffet tool to check for any 404 HTTP codes:
$ check-avd-404 docker run --network container:webdoc_avd raviqqe/muffet \ http://127.0.0.1:8000 \ -e ".*fonts.gstatic.com.*" \ -e ".*edit.*" \ -f --limit-redirections=3 \ --timeout=60 http://127.0.0.1:8000/docs/installation/development/ 404 http://127.0.0.1:8000/docs/installation/development/setup-environment2.md make: *** [check-avd-404] Error 1
This process is also implemented in project CI to protect documentation against dead links.
