Mattermost

Send release notifications to Mattermost

Config

announce:
  mattermost:
    enabled: true
    webhook_url: "{{ Env.MATTERMOST_WEBHOOK_URL }}"
    channel: "releases"
    username: "release-bot"
    icon_url: "https://example.com/icon.png"
    message_template: "{{ ProjectName }} {{ Tag }} has been released! {{ ReleaseURL }}"

Create an incoming webhook in Main Menu > Integrations > Incoming Webhooks. The webhook payload format is the same as Slack's, so the setup should feel familiar if you have used the Slack provider.

Optional overrides

The channel, username, and icon_url fields are all optional. When omitted, Mattermost uses the defaults configured on the webhook itself.

• channel -- Override the default channel (e.g. town-square or releases).
• username -- Override the display name of the bot post.
• icon_url -- Override the bot's avatar with a custom image URL.

Environment variables

Store the webhook URL in an environment variable rather than committing it to your config file:

webhook_url: "{{ Env.MATTERMOST_WEBHOOK_URL }}"
