Creating Releases using Webhooks

What does this mean?

A webhook is a notification from one service to another. Put simply, a webhook is used to notify ContentDB that the git repository has changed.

ContentDB offers the ability to automatically create releases using webhooks from either Github or Gitlab. If you're not using either of those services, you can also use the API to create releases.

The process is as follows:

  1. The user creates an API Token and a webhook to use it. This can be done automatically for Github.
  2. The user pushes a commit to the git host (Gitlab or Github).
  3. The git host posts a webhook notification to ContentDB, using the API token assigned to it.
  4. ContentDB checks the API token and issues a new release.

This feature is in beta, and is only available for Trusted Members.

Setting up

GitHub (automatic)

  1. Go to your package's page.
  2. Make sure that the repository URL is set to a Github repository. Only github.com is supported.
  3. Go to "Releases" > "+", and click "Setup webhook" at the top of the create release page. If you do not see this, either the repository isn't using Github or you do not have permission to use webhook releases (ie: you're not a Trusted Member).
  4. Grant ContentDB the ability to manage Webhooks.
  5. Set the event to either "New tag or Github Release" (highly recommended) or "Push".

N.B.: GitHub uses tags to power GitHub Releases, meaning that creating a webhook on "New tag" will sync GitHub and ContentDB releases.

GitHub (manual)

  1. Create an API Token by visiting your profile and clicking "API Tokens: Manage".
  2. Copy the access token that was generated.
  3. Go to the repository's settings > Webhooks > Add Webhook.
  4. Set the payload URL to https://content.minetest.net/github/webhook/
  5. Set the content type to JSON.
  6. Set the secret to the access token that you copied.
  7. Set the events
  8. If you want a rolling release, choose "just the push event".
  9. Or if you want a stable release cycle based on tags, choose "Let me select" > Branch or tag creation.

GitLab (manual)

  1. Create an API Token by visiting your profile and clicking "API Tokens: Manage".
  2. Copy the access token that was generated.
  3. Go to the repository's settings > Integrations.
  4. Set the URL to https://content.minetest.net/gitlab/webhook/
  5. Set the secret token to the access token that you copied.
  6. Set the events
    • If you want a rolling release, choose "Push events".
    • Or if you want a stable release cycle based on tags, choose "Tag push events".

Configuring

Setting minimum and maximum Minetest versions

This feature is unimplemented.

  1. Open up the conf file for the package. This will be game.conf, mod.conf, modpack.conf, or texture_pack.conf depending on the content type.
  2. Set min_protocol and max_protocol to the respective protocol numbers of the Minetest versions.
    • 0.4 = 32
    • 5.0 = 37
    • 5.1 = 38
