Starting with Docker 20.10, `--hostname` seems to have the side-effect
of making Docker's internal DNS server resolve said hostname to the IP
address of the container.
Because we were giving the mailer service a hostname of `matrix.DOMAIN`,
all requests destined for `matrix.DOMAIN` originating from other
services on the container network were resolving to `matrix-mailer`.
This is obviously wrong.
Initially reported here: https://github.com/spantaleev/matrix-docker-ansible-deploy/pull/748
We normally try to not use the public hostname (and IP address) on the
container network and try to make services talk to one another locally,
but it sometimes could happen.
With this, we use a `matrix-mailer` hostname for the matrix-mailer
container. My testing shows that it doesn't cause any trouble with
email deliverability.
If a service is enabled, a database for it is created in postgres with a uniqque password. The service can then use this database for data storage instead of relying on sqlite.
The Docker 19.04 -> 20.10 upgrade contains the following change
in `/usr/lib/systemd/system/docker.service`:
```
-BindsTo=containerd.service
-After=network-online.target firewalld.service containerd.service
+After=network-online.target firewalld.service containerd.service multi-user.target
-Requires=docker.socket
+Requires=docker.socket containerd.service
Wants=network-online.target
```
The `multi-user.target` requirement in `After` seems to be in conflict
with our `WantedBy=multi-user.target` and `After=docker.service` /
`Requires=docker.service` definitions, causing the following error on
startup for all of our systemd services:
> Job matrix-synapse.service/start deleted to break ordering cycle starting with multi-user.target/start
A workaround which appears to work is to add `DefaultDependencies=no`
to all of our services.
After recently updating my matrix-docker-ansible-deploy installation, matrix-appservice-discord would refuse to start, logging ECONNREFUSED to https://matrix.[mydomain]:443, which was resolving to 172.18.0.2 due to the `--hostname` in mailer grabbing that hostname.
Curious why the IRC bridge didn't have this issue, I looked into it, and it was connecting to `http://matrix-synapse:8008`. Correcting this one to that URL resolved the issue.
ma1sd requires the openid endpoints for certain functionality.
Example: 90b2b5301c/src/main/java/io/kamax/mxisd/auth/AccountManager.java (L67-L99)
If federation is disabled, we still need to expose these openid APIs on the
federation port.
Previously, we were doing similar magic for Dimension.
As per its documentation, when running unfederated, one is to enable
the openid listener as well. As per their recommendation, people
are advised to do enable it on the Client-Server API port
and use the `federationUrl` variable to override where the federation
port is (making federation requests go to the Client-Server API).
Because ma1sd always uses the federation port (unless you do some
DNS overwriting magic using its configuration -- which we'd rather not
do), it's better if we just default to putting the `openid` listener
where it belongs - on the federation port.
With this commit, we retain the "automatically enable openid APIs" thing
we've been doing for Dimension, but move it to the federation port instead.
We also now do the same thing when ma1sd is enabled.
We've had a report of the `connection` value getting cut off,
supposedly because it contains something that breaks off the string.
Using `|to_json` takes care of it.
This may be a bit premature, because the bridge didn't work for me
the last time I tried it (RC3).
Some bugs have been fixed to make our config compatible with v1.0.0
though, so it may work for some people (especially those starting
fresh).
I'm not for shipping potentially broken things, but given that we were
using `docker.io/halfshot/matrix-appservice-discord:latest` and that
points to v1.0.0 already (with no other tag we can use), our setup was
already broken in any case.
Now, at least it has some chance of running.
Some people requested that `--tags=start` not set up service autostart.
One can now do `--tags=start --extra-vars="matrix_services_autostart_enabled=false"`
to just start services ones and not set up autostarting.
It's not like it worked anyway, because we don't have the necessary
services installed for transcription (Jigasi), nor recording (Jibri).
Disabling these, should hopefully disable their related elements
in the Jitsi Web UI.

The Jitsi Web and JVB containers now (in build 5142) always
start by bulding their own default configuration
(`config.js` and `sip-communicator.properties`, respectively).
The fact that we were generating these files ourselves was no longer of use,
because our configuration was thrown away in favor of the one created
by the containers on startup.
With this commit, we're completely redoing things. We no longer
generate these configuration files. We try to pass the proper
environment variables, so that Jitsi services can generate the
configuration files themselves.
Besides that, we try to use the "custom configuration" mechanism
provided by Jitsi Web and Jitsi JVB (`custom-config.js` and
`custom-sip-communicator.properties`, respectively), so that
we and our users can inject additional configuration.
Some configuration options we had are gone now. Others are no longer
controllable via variables and need to be injected using
the `_config_extension` variables that we provide.
The validation logic that is part of the role should take care
to inform people about how to upgrade (if they're using some custom
configuration, which needs special care now). Most users should not
have to do anything special though.
Since the switch from `-v` to `--mount` (in 1fca917ad1),
we've regressed when `matrix_ssl_retrieval_method == 'none'`.
In such a case, we don't create `/matrix/ssl` directories at all
and shouldn't be trying to mount them into the `matrix-nginx-proxy`
container.
Previously, with `-v`, Docker would auto-create them, effectively hiding
our mistake. Now that `--mount` doesn't do such auto-creation magic,
the `matrix-nginx-proxy` container was failing to start.
