We've had that logic in 2 places so far, leading to duplication
and a maintenance burden.
In the future, we'll also have an import-postgres feature,
which will also need Postgres version detection,
leading to more benefit from that logic being reusable.
Fixes#18 (Github issue).
It would probably be better if we serve our own page,
as the Matrix one says:
"To use this server you'll need a Matrix client", which
is true, but we install Riot by default and it'd be better if we mention
that instead.
If uppercase is used, certain tools (like certbot) would cause trouble.
They would retrieve a certificate for the lowercased domain name,
but we'd try to use it from an uppercase-named directory, which will
fail.
Besides certbot, we may experience other trouble too.
(it hasn't been investigated how far the breakage goes).
To fix it all, we lowercase `host_specific_hostname_identity` by default,
which takes care of the general use-case (people only setting that
and relying on us to build the other domain names - `hostname_matrix`
and `hostname_riot`).
For others, who decide to override these other variables directly
(and who may work around us and introduce uppercase there directly),
we also have the sanity-check tool warn if uppercase is detected
in any of the final domains.
Adds support for managing certificates manually and for
having the playbook generate self-signed certificates for you.
With this, Let's Encrypt usage is no longer required.
Fixes Github issue #50.
This is in line with what the recommendation is for matrix-corporal.
A value higher than 30 seconds is required to satisfy Riot
(and other clients') default long-polling behavior.
It looks like SELinux can be left running without any (so far) negative
effects on our Matrix services.
There's no need to use `:z` or `:Z` options when mounting volumes either.
This means that files we create are labeled with a default context
(which may not be ideal if we only want them used from containers),
but it's compatible and doesn't cause issues.
Relabelling files is probably something we wish to stay away from,
especially for things like the media store, which contains lots of
files and is possibly on a fuse-mounted (S3/goofys) filesystem.
The new image is built in a much better way (2-stage build)
and is 10x smaller.
In terms of Goofys version recency, it's about the same..
Both images (and others alike) seem to not use version tags,
but rather some `:latest` (master), with ewoutp/goofys being a bit
more recent than clodproto/goofys.
Not using version tags is good (in this case),
because the last Goofys release seems to be from about a year ago
and there had been a bunch of bugfixes afterwards.
This is described in Github issue #58.
Until now, we had the variable, but if you redefined it, you'd run
into multiple problems:
- we actually always mounted some "storage" directory to the Synapse
container. So if your media store is not there, you're out of luck
- homeserver.yaml always hardcoded the path to the media store,
as a directory called "media-store" inside the storage directory.
Relocating to outside the storage directory was out of the question.
Moreover, even if you had simply renamed the media store directory
(e.g. "media-store" -> "media_store"), it would have also caused trouble.
With this patch, we mount the media store's parent to the Synapse container.
This way, we don't care where the media store is (inside storage or
not). We also don't assume (anymore) that the final part of the path
is called "media-store" -- anything can be used.
The "storage" directory and variable (`matrix_synapse_storage_path`)
still remain for compatibility purposes. People who were previously
overriding `matrix_synapse_storage_path` can continue doing so
and their media store will be at the same place.
The playbook no longer explicitly creates the `matrix_synapse_storage_path` directory
though. It's not necessary. If the media store is specified to be within it, it will
get created when the media store directory is created by the playbook.
Previously, it was more necessary to have it
(because we had a dependency between matrix-synapse and matrix-nginx-proxy)..
But nowadays, it can be removed without negative side effects.
Restarting matrix-nginx-proxy is especially bad when the proxy is not installed at all.
mxisd supports several identity stores. Add support to configure two of them:
* synapseSql (storing identities directly in Synapse's database)
* LDAP
This removed the need to copy `mxisd.yaml.j2` to the inventory in case one wants
to use LDAP as identity store. Note that the previous solution (copying
`mxisd.yaml.j2` was poor because of two reasons:
* The copy remains outdated in case the original is updated in future versions
of this repo.
* The role's configuration should be in one place (configured only through role
variables) instead of in multiple.
Configuring more identity stores through role variables can be supported in the
future.
This is provoked by Github issue #46.
No client had made use of the well-known mechanism
so far, so the set up performed by this playbook was not tested
and turned out to be a little deficient.
Even though /.well-known/matrix/client is usually requested with a
simple request (no preflight), it's still considered cross-origin
and [CORS](https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS)
applies. Thus, the file always needs to be served with the appropriate
`Access-Control-Allow-Origin` header.
Github issue #46 attempts to fix it at the "reverse-proxying" layer,
which may work, but would need to be done for every server.
It's better if it's done "upstream", so that all reverse-proxy
configurations can benefit.
Trying to:
- stay closer to naming in Synapse (autojoin -> auto_join)
- not create new variable namespaces (`matrix_homeserver_`),
when existing ones (`matrix_synapse_`) are more suitable
- allow `null` (`~`) values for `matrix_riot_web_welcome_user_id`
- render things like `auto_join_rooms` in `homeserver.yaml` more prettily
- fix breakage in `config.json` where `matrix_riot_web_roomdir_servers`
was rendered as YAML and not as JSON
- simplify code (especially in riot-web's `config.json`), which used
`if` statements that could have been omitted
- avoid changing comments in `homeserver.yaml` which are not ours,
so that we can keep closer to the configuration file generated by upstream
Pretty much all variables live in their own `matrix_<whatever>`
prefix now and are grouped closer together in the default
variables file (`roles/matrix-server/defaults/main.yml`).
It should be `/bin/mkdir` and `/bin/chown` on Ubuntu 18.04 for example.
Still, it doesn't seem like we need to create and chown these
directories at all, since the playbook takes care of creating them
and setting appropriate permission by itself.
If a network like `matrix-whatever` already exists for some reason,
the `docker_network` module would not create our `matrix` network.
Working around it by avoiding `docker_network` and doing it manually.
Fixes Github issue #12
`--log-driver=none` is used for all Docker containers now.
All these containers are started through systemd anyway and get logged in journald,
so there's no need for Docker to be logging the same thing using the default `json-file` driver.
Doing that was growing `/var/lib/docker/containers/..` infinitely until service/container restart.
As a result of this, things like `docker logs matrix-synapse` won't work anymore.
`journalctl -u matrix-synapse` is how one can see the logs.
If the playbook were to run with `--tags=setup-nginx-proxy`,
it wouldn't go into `setup_corporal.yml`, which meant it wouldn't
perform a bunch of `set_fact` calls which override important
nginx proxy configuration.
We run these variable overrides on each call now (tagged with `always`)
to avoid such problems in the future.
This disables federation on the 80 port, as it's
not necessary. We also disable the old Angular webclient.
For the federation port (8448), we disable the client APIs
as those are not necessary. Those can even cause trouble
if one doesn't know about them and thinks that guarding the client
APIs at the 80 port is enough.
Moving away from using the default bridge network to using our own.
This isolates our services from other Docker containers running
on the default network on the same host.
The benefits are that:
- isolation is a little better - we no longer share a default
bridge network with any other containers that might be running on the host
- there are no longer hard dependencies - we do service discovery
by DNS name, and not via explicit `--link` usage during container start,
so containers can start out of order and fail without bringing down others
with them
(`matrix-nginx-proxy` can continue running, even if one of the other services dies)
In the future, when other services get introduced,
the increased resilience and simplicity will help as well.
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)
