What is ddev-addon-template?

This repository is a template for providing DDEV addons and services.

In ddev v1.19+ addons can be installed from the command line using the ddev get command, for example, ddev get drud/ddev-addon-template or ddev get drud/ddev-drupal9-solr.

A repository like this one is the way to get started. You can create a new repo from this one by clicking the template button in the top right corner of the page.

Components of the repository

• The fundamental contents of the add-on service or other component. For example, in this template there is a docker-compose.addon-template.yaml file.
• An install.yaml file that describes how to install the service or other component.
• A test suite in test.bats that makes sure the service continues to work as expected.
• Github actions setup so that the tests run automatically when you push to the repository.

Getting started

1. Choose a good descriptive name for your add-on. It should probably start with "ddev-" and include the basic service or functionality. If it's particular to a specific CMS, perhaps ddev-<CMS>-servicename.
2. Create the new template repository by using the template button.
3. Globally replace "addon-template" with the name of your add-on.
4. Add the files that need to be added to a ddev project to the repository. For example, you might remove docker-composeaddon-template.yaml with the docker-compose.*.yaml for your recipe.
5. Update the install.yaml to give the necessary instructions for installing the add-on.

• The fundamental line is the project_files directive, a list of files to be copied from this repo into the project .ddev directory.
• You can optionally add files to the global_files directive as well, which will cause files to be placed in the global .ddev directory, ~/.ddev.
• Finally, pre_install_commands and post_install_commands are supported. These can use the host-side environment variables documented in ddev docs.

6. Update tests/test.bats to provide a reasonable test for the repository. You can run it manually with bats tests and it will be run on push and nightly as well. Please make sure to attend to test failures when they happen. Others will be depending on you. bats is a simple testing framework that just uses bash. You can install it with brew install bats-core or see other techniques. See bats tutorial.
7. When everything is working, including the tests, you can push the repository to GitHub.
8. Create a release on GitHub.
9. Test manually with ddev get <owner/repo>.
10. Update the README.md to describe the add-on, how to use it, and how to contribute. If there are any manual actions that have to be taken, please explain them. If it requires special configuration of the using project, please explain how to do those. Examples in drud/ddev-drupal9-solr, drud/ddev-memcached, and drud/ddev-beanstalkd.
11. Add a good short description to your repo, and add the label "ddev-get". It will immediately be added to the list provided by ddev get --list --all.
12. When it has matured you will hopefully want to have it become an "official" maintained add-on. Open an issue in the ddev queue for that.

Note that more advanced techniques are discussed in DDEV docs.
