Slavi Pantaleev 66cdc7bf5a Clean up worker.yaml generation a bit and make it more flexible 2021-01-25 13:02:01 +02:00
Slavi Pantaleev 1462409b34 Fix worker listening addresses
Not specifying bind addresses for the worker resulted in this warning:

> synapse.app - 47 - WARNING - None - Failed to listen on 0.0.0.0, continuing because listening on [::]

Additionally, metrics listening only on 127.0.0.1 seems like a no-op.
Only having it accessible from within the container is likely not what
we intend. Changed that to all interfaces as well.

Whether it actually gets exposed or not depends on the systemd service
and `matrix_synapse_workers_container_host_bind_address`.

Slavi Pantaleev 01747c8cc4 Prevent Synapse warning about enabling metric listeners with enable_metrics: false

Slavi Pantaleev 70796703d3 Run Synapse workers in their own containers
This switches the `docker exec` method of spawning
Synapse workers inside the `matrix-synapse` container with
dedicated containers for each worker.

We also have dedicated systemd services for each worker,
so this are now:
- more consistent with everything else (we don't use systemd
instantiated services anywhere)
- we don't need the "parse systemd instance name into worker name +
port" part
- we don't need to keep track of PIDs manually
- we don't need jq (less depenendencies)
- workers dying would be restarted by systemd correctly, like any other
service
- `docker ps` shows each worker separately and we can observe resource
usage

Marcel Partap e892ac464f synapse workers: untangle config template and specify bind address

Marcel Partap 2d1b9f2dbf synapse workers: reworkings + get endpoints from upstream docs via awk
(yes, a bit awkward and brittle… xD)

Marcel Partap 501efee07e synapse workers: supply systemd with actual worker PIDs (requires jq)
also, worker.yaml.j2:
  - hone worker_name
  - remove worker_pid_file entry (would only be used if worker_daemonize
    set to true; also, synapse only knows about the container namespace
    and thus can not provide the required host-view PID)

Marcel Partap d2e61af224 Add worker_name to synapse worker config template
& restrict federation listener; frontend_proxy / user_dir don't need it

Marcel Partap 353bc7c362 Add initial support for synapse workers
· needs documentation; no checks yet for port clashes or typos in worker name
· according to https://github.com/matrix-org/synapse/wiki/Workers-setup-with-nginx#results
  about 90% of requests go to the synchrotron endpoint
· thus, the synchrotron worker is especially suited to be load-balanced
· most of the other workers are documented to support only a single instance
