Slavi Pantaleev 00ae435044 Use |to_json filter for serializing booleans to JSON
This should account for all cases where we were still doing such a thing.

Improvement suggested in #65 (Github issue).

Slavi Pantaleev b222d26c86 Switch to managing cronjobs with the Ansible cron module
As suggested in #65 (Github issue), this patch switches
cronjob management from using templates to using Ansible's `cron` module.

It also moves the management of the nginx-reload cronjob to `setup_ssl_lets_encrypt.yml`,
which is a more fitting place for it (given that this cronjob is only required when
Let's Encrypt is used).

Pros:
- using a module is more Ansible-ish than templating our own files in
special directories

- more reliable: will fail early (during playbook execution) if `/usr/bin/crontab`
is not available, which is more of a guarantee that cron is working fine
(idea: we should probably install some cron package using the playbook)

Cons:
- invocation schedule is no longer configurable, unless we define individual
variables for everything or do something smart (splitting on ' ', etc.).
Likely not necessary, however.

- requires us to deprecate and clean-up after the old way of managing cronjobs,
because it's not compatible (using the same file as before means appending
additional jobs to it)

Slavi Pantaleev f92c4d5a27 Use Ansible dig lookup instead of calling the dig program
This means we no longer have a dependency on the `dig` program,
but we do have a dependency on `dnspython`.

Improves things as suggested in #65 (Github issue).

Slavi Pantaleev 5135c0cc0a Add Ansible guide and Ansible version checks
After having multiple people report issues with retrieving
SSL certificates, we've finally discovered the culprit to be
Ansible 2.5.1 (default and latest version on Ubuntu 18.04 LTS).

As silly as it is, certain distributions ("LTS" even) are 13 bugfix
versions of Ansible behind.

From now on, we try to auto-detect buggy Ansible versions and tell the
user. We also provide some tips for how to upgrade Ansible or
run it from inside a Docker container.

My testing shows that Ansible 2.4.0 and 2.4.6 are OK.
All other intermediate 2.4.x versions haven't been tested, but we
trust they're OK too.

From the 2.5.x releases, only 2.5.0 and 2.5.1 seem to be affected.
Ansible 2.5.2 corrects the problem with `include_tasks` + `with_items`.

Slavi Pantaleev 99af4543ac Replace include usage with include_tasks and import_tasks
The long-deprecated (since Ansible 2.4) use of include is
no more.

Slavi Pantaleev 76506f34e0 Make media-store restore work with server files, not local
This is a simplification and a way to make it consistent with
how we do Postgres imports (see 6d89319822), using
files coming from the server, not from the local machine.

By encouraging people NOT to use local files,
we potentially avoid problems such as #34 (Github issue),
where people would download `media_store` to their Mac's filesystem
and case-sensitivity issues will actually corrupt it.

By not encouraging local files usage, it's less likely that
people would copy (huge) directories to their local machine like that.

Slavi Pantaleev f472c1b9e5 Ensure psql returns a failure exit code when it fails
Until now, if the .sql file contained invalid data, psql would
choke on it, but still return an exit code of 0.
This is very misleading.

We need to pass `-v ON_ERROR_STOP=1` to make it exit
with a proper error exit code when failures happen.

Slavi Pantaleev a7f791f8f9 Make Postgres version detection logic reusable to ease maintenance
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.

Slavi Pantaleev 4757c13a2e Do not install openssl if not necessary
Fix for d28bdb3258.

Slavi Pantaleev 12b65d8ccc Serve a non-scary page at the matrix domain
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.

Slavi Pantaleev b9b5674b8a Lowercase host_specific_hostname_identity to prevent troubles
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.

Slavi Pantaleev 9f163b2bf5 Do not disable SELinux on RedHat systems
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.

Slavi Pantaleev b9e5ad6c66 Upgrade Docker images for various components 2018-12-20 15:10:53 +02:00
Slavi Pantaleev 97280c7cc1 Change Goofys Docker image (clodproto/goofys -> ewoutp/goofys)
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.

Slavi Pantaleev bfcceb1e82 Make it safer to override matrix_synapse_media_store_path
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.

Slavi Pantaleev 60c7af93fe
Do not restart matrix-nginx-proxy during media store import
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.
