Setting up Hookshot (optional)

The playbook can install and configure matrix-hookshot for you.

Hookshot can bridge Webhooks from software project management services such as GitHub, GitLab, JIRA, and Figma, as well as generic webhooks.

See the project's documentation to learn what it does in detail and why it might be useful to you.

Note: the playbook also supports matrix-appservice-webhooks, which however is soon to be archived by its author and to be replaced by hookshot.

Setup Instructions

Refer to the official instructions to learn what the individual options do.

1. For each of the services (GitHub, GitLab, Jira, Figma, generic webhooks) fill in the respective variables matrix_hookshot_service_* listed in main.yml as required.
2. Take special note of the matrix_hookshot_*_enabled variables. Services that need no further configuration are enabled by default (GitLab, Generic), while you must first add the required configuration and enable the others (GitHub, Jira, Figma).
3. If you're setting up the GitHub bridge, you'll need to generate and download a private key file after you created your GitHub app. Copy the contents of that file to the variable matrix_hookshot_github_private_key so the playbook can install it for you, or use one of the other methods explained below.
4. If you've already installed Matrix services using the playbook before, you'll need to re-run it (--tags=setup-all,start). If not, proceed with configuring other playbook services and then with Installing. Get back to this guide once ready. Hookshot can be set up individually using the tag setup-hookshot.
5. Refer to Hookshot's official instructions to start using the bridge. Note that the different listeners are bound to certain paths (see matrix_hookshot_matrix_nginx_proxy_configuration in init.yml): by default webhooks root is /hookshot/webhooks/.

Other configuration options are available via the matrix_hookshot_configuration_extension_yaml and matrix_hookshot_registration_extension_yaml variables, see the comments in main.yml for how to use them.

Manage GitHub Private Key with matrix-aux role

The GitHub bridge requires you to install a private key file. This can be done in multiple ways:

• copy the contents of the downloaded file and set the variable matrix_hookshot_github_private_key to the contents (see example in main.yml).
• somehow copy the file to the path {{ matrix_hookshot_base_path }}/{{ matrix_hookshot_github_private_key_file }} (default: /matrix/hookshot/private-key.pem) on the server manually.
• use the matrix-aux role to copy the file from an arbitrary path on your ansible client to the correct path on the server.

To use matrix-aux, make sure the matrix_hookshot_github_private_key variable is empty. Then add to matrix-aux configuration like this:

matrix_aux_file_definitions:
  - dest: "{{ matrix_hookshot_base_path }}/{{ matrix_hookshot_github_private_key_file }}"
    content: "{{ lookup('file', '/path/to/your-github-private-key.pem') }}"
    mode: '0400'
    owner: "{{ matrix_user_username }}"
    group: "{{ matrix_user_groupname }}"

For more info see the documentation in the matrix-aux base configuration file.

Provisioning API

The provisioning API will be enabled automatically if you set matrix_dimension_enabled: true and provided a matrix_hookshot_provisioning_secret, unless you override it either way. To use hookshot with dimension, you will need to enter as "Provisioning URL": http://matrix-hookshot:9002, which is made up of the variables matrix_hookshot_container_url and matrix_hookshot_provisioning_port.

Metrics

If metrics are enabled, they will be automatically available in the builtin Prometheus and Grafana, but you need to set up your own Dashboard for now. If additionally metrics proxying for use with external Prometheus is enabled (matrix_nginx_proxy_proxy_synapse_metrics), hookshot metrics will also be available (at matrix_hookshot_metrics_endpoint, default /hookshot/metrics, on the stats subdomain) and with the same password. See also the Prometheus and Grafana docs.
