How to update an existing addon¶

Addons will need to be updated now and then. The basic process for updating an addon is to:

Choose a local project to work with¶

Ideally, select a project that already works with an existing version of the addon. This way, you can checkthat the new version continues to work as expected, and that migrations for example run correctly.

If you don’t have such a project, the next best thing is to create a new project on the Control Panelcontaining the addon, and then set that up locally.

Uninstall the addon locally if necessary¶

You will find the addon listed in requirements.in - remove it from there, so that when you build thelocal container it will no longer try to install the old version.

Remove it from each of these places.

You will also find it listed in INSTALLEDADDONS in settings.py - _leave it there.

Clone the addon repository to addons-dev¶

In addons-dev, clone the addon from its VCS repository. It should look something like this:

  1. addons-dev/
  2.     susan-example-application/
  3.         addon.json
  4.         LICENSE
  5.         MANIFEST.in
  6.         README.rst
  7.         setup.py
  8.         susan_example_application/
  9.             __init__.py

Check that you have the appropriate version cloned.

Placing the addon into addons-dev will override any version that has been installed into the projectusing the requirements file.

Run divio project develop¶

If the new version is different from the previously installed version and includes changed dependencies, oryou want to check exactly what it will do when when the project is built, you should run:

  1. divio project develop <package name>

This processes the addon, adding:

  1. -e /app/addons-dev/<package name>

to the requirements.in.

You will need to run this again if you make any changes in the addon that involve dependencies orinstallation of components.

Work on the code¶

Restart the runserver (docker-compose up), and check that the addon continues to work asexpected (or fails to work, if that is what previously happened).

Make and test any changes you want to make.

Push your changes¶

When you’re satisfied, you’re ready to update the addon.

Don’t forget to bump the version number in the init.py.

When you have finished all your updates, commit and push your changes to the addon’s repository (ormake a pull request if it’s not your own).

Remember that if your addon is a wrapper for installing a reusable application,its version number should track the version number of the application, in an additional dottedincrement - for example, the addon version 1.5.4.2 tracking application version 1.5.4should become 1.5.4.3.

Upload the new addon version¶

Finally, in the addon directory, run:

  1. divio addon validate

to check it, and:

  1. divio addon upload

to push it to the addons system.

Test it on the Control Panel¶

For completeness, check that the new version of your addon can be installed and deployed in aproject.

Place the new version in the appropriate channel¶

By default, your newly-uploaded addon version will be placed in the Alpha channel. In the _Addons_section of the Control Panel, put it in the Beta or Stable channels if appropriate.
