Until now, we were starting from a fresh configuration, as generated
by Synapse and manipulating it with regex and line replacements,
until we made it work.
This is more fragile and less predictable, so we're moving to a static
configuration file generated from a Jinja template.
The upside is that configuration will be stable and predictable.
The downside of this new approach is that any manual configuration changes
after the playbook is done, will be thrown away on future playbook
invocations.
There are 2 ways to work around the need for manual configuration
changes though:
- making them part of this playbook and its default template
configuration files (which benefits everyone)
- going your own way for a given host and overriding the template files
that gets used (that is, the
`matrix_synapse_template_synapse_homeserver` or
`matrix_synapse_template_synapse_log` variables)
This playbook does not set up guest access in Synapse anyway,
so until the need comes (or someone asks for it), guest access
is removed from riot-web's UI too.
As for supporting custom URLs, this is also not something
that seems like it'd be useful to most deployments.
This playbook just tries to avoid trying to setup a Postgres 10
database with existing 9.x files, as that makes Postgres complain.
Due to this, existing installs (still on 9.x) are detected
and left on Postgres 9.x.
They need to be upgraded to Postgres 10.x manually.
Switching from from avhost/docker-matrix (silviof/docker-matrix)
to matrixdotorg/synapse.
The avhost/docker-matrix (silviof/docker-matrix) image used to bundle
in the coturn STUN/TURN server, so as part of the move,
we're separating this to a separately-ran service
(matrix-coturn.service, powered by instrumentisto/coturn-docker-image)
When using matrix-nginx-proxy, the file permissions are organized
in a way that matrix-nginx-proxy could read the challenge files
produced by acmetool.
However, when another own/external webserver was used (like nginx
with our generated sample configuration), this could not work.
From on we're proxying the HTTP requests to port :402 in such a case,
which fixes the problem.
The matrix-nginx-proxy was reloaded on the 3rd day of the month (`15 4 3 * *`),
which makes no sense - it's too infrequently.
It's in line with the renewal time now (+5 minutes).
As described here (
https://github.com/matrix-org/synapse/issues/2438#issuecomment-327424711
), using own SSL certificates for the federation port is more fragile,
as renewing them could cause federation outages.
The recommended setup is to use the self-signed certificates generated
by Synapse.
On the 443 port (matrix-nginx-proxy) side, we still use the Let's Encrypt
certificates, which ensures API consumers work without having to trust
"our own CA".
Having done this, we also don't need to ever restart Synapse anymore,
as no new SSL certificates need to be applied there.
It's just matrix-nginx-proxy that needs to be restarted, and it doesn't
even need a full restart as an "nginx reload" does the job of swithing
to the new SSL certificates.
Moving keeps everything in the /matrix directory, so that we
wouldn't contaminate anything else on the system or risk
clashing with something else.
Also retrieving certificates separately for the Riot and Matrix domains,
which should help in multiple ways:
- allows them to be very different (completely separate base domain..)
- allows for Riot to be disabled for the playbook some time later
and still have the code not break
The goal is to allow these to be on separate partitions
(including remote ones in the future).
Because the `silviof/docker-matrix` image chowns
everything to MATRIX_UID:MATRIX_GID on startup,
we definitely don't want to include `media_store` in it.
If it's on a remote FS, it would cause a slow startup.
Also, adding some safety checks to the "import media store"
task, after passing a wrong path to it on multiple occassions and
wondering what's wrong.
Also, making logging configurable. The default of keeping 10x100MB
log files is likely excessive and people may want to change that.
It was trying to omit the `-a` flag, but that wasn't enough,
because the underlying `register_new_matrix_user` command
prompts interactively if it doesn't see the `-a` flag
(it doesn't default to non-admin).
We need to answer such interactive prompts.
