* Replace installation command shortcut for the "just" program with the most conservative raw ansible-playbook command
This commit replaces installation command shortcut ("recipe") for the "just" program with the raw ansible-playbook command, so that the shortcut will be added to it later. The command is so conservative that failure of the command will mean something is clearly broken.

* Add description about shortcut command with the "just" program to the ansible-playbook command with "setup-all" and "start" tags
It also explains difference between "just install-all" and "just setup-all" recipes. The explanation is based on docs/playbook-tags.md

* Update raw ansible-playbook command to have it do what "just install-all" or "just setup-all" does
Since "just install-all" or "just setup-all" invokes "ensure-matrix-users-created" as well, it needs adding to the raw ansible-playbook command.

* Remove "ensure-matrix-users-created" from the raw ansible-playbook command which does not need it
Also: update the "just" recipes accordingly. "just install-all" and "just setup-all" run "ensure-matrix-users-created" tag as well, therefore they need to be replaced with "run-tags" recipes to skip "ensure-matrix-users-created"

* Add description about "ensure-matrix-users-created" and create a list with description about shortcut commands with "just"
This commit also fixes list item capitalization and punctuation.

* Replace "run the installation command" with "run the playbook with tags"
Now that shortcut commands for the "just" program are displayed along with the existing "installation command", this commit replaces "run the installation command" with "run the playbook with tags" in order to prevent misunderstanding and confusion.

Enabling metrics and graphs for Postgres (optional)
Expanding on the metrics exposed by the synapse exporter and the node exporter, the playbook enables the postgres exporter that exposes more detailed information about what's happening on your postgres database.
Adjusting the playbook configuration
To enable the postgres exporter, add the following configuration to your inventory/host_vars/matrix.example.com/vars.yml file:
prometheus_postgres_exporter_enabled: true
Installing
After configuring the playbook, run it with playbook tags as below:
ansible-playbook -i inventory/hosts setup.yml --tags=setup-all,start
The shortcut commands with just program are also available: just run-tags install-all,start or just run-tags setup-all,start
just run-tags install-all,start is useful for maintaining your setup quickly when its components remain unchanged. If you adjust your vars.yml to remove other components, you'd need to run just run-tags setup-all,start, or these components will still remain installed. For more information about just shortcuts, take a look at this page: Running just commands
What does it do?
| Name | Description |
|---|---|
prometheus_postgres_exporter_enabled |
Enable the postgres prometheus exporter. This sets up the docker container, connects it to the database and adds a 'job' to the prometheus config which tells prometheus about this new exporter. The default is 'false' |
prometheus_postgres_exporter_database_username |
The 'username' for the user that the exporter uses to connect to the database. The default is 'matrix_prometheus_postgres_exporter' |
prometheus_postgres_exporter_database_password |
The 'password' for the user that the exporter uses to connect to the database. By default, this is auto-generated by the playbook |
prometheus_postgres_exporter_container_labels_traefik_enabled |
If set to true, exposes the Postgres exporter metrics on https://matrix.example.com/metrics/postgres-exporter for usage with an external Prometheus server. To password-protect the metrics, see matrix_metrics_exposure_http_basic_auth_users on that other documentation page. |
