This makes all containers (except mautrix-telegram and
mautrix-whatsapp), start as a non-root user.
We do this, because we don't trust some of the images.
In any case, we'd rather not trust ALL images and avoid giving
`root` access at all. We can't be sure they would drop privileges
or what they might do before they do it.
Because Postfix doesn't support running as non-root,
it had to be replaced by an Exim mail server.
The matrix-nginx-proxy nginx container image is patched up
(by replacing its main configuration) so that it can work as non-root.
It seems like there's no other good image that we can use and that is up-to-date
(https://hub.docker.com/r/nginxinc/nginx-unprivileged is outdated).
Likewise for riot-web (https://hub.docker.com/r/bubuntux/riot-web/),
we patch it up ourselves when starting (replacing the main nginx
configuration).
Ideally, it would be fixed upstream so we can simplify.
With this change, the following roles are now only dependent
on the minimal `matrix-base` role:
- `matrix-corporal`
- `matrix-coturn`
- `matrix-mailer`
- `matrix-mxisd`
- `matrix-postgres`
- `matrix-riot-web`
- `matrix-synapse`
The `matrix-nginx-proxy` role still does too much and remains
dependent on the others.
Wiring up the various (now-independent) roles happens
via a glue variables file (`group_vars/matrix-servers`).
It's triggered for all hosts in the `matrix-servers` group.
According to Ansible's rules of priority, we have the following
chain of inclusion/overriding now:
- role defaults (mostly empty or good for independent usage)
- playbook glue variables (`group_vars/matrix-servers`)
- inventory host variables (`inventory/host_vars/matrix.<your-domain>`)
All roles default to enabling their main component
(e.g. `matrix_mxisd_enabled: true`, `matrix_riot_web_enabled: true`).
Reasoning: if a role is included in a playbook (especially separately,
in another playbook), it should "work" by default.
Our playbook disables some of those if they are not generally useful
(e.g. `matrix_corporal_enabled: false`).
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.
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 reverts commit 8d774db3bc.
Docker is released in the Docker CE stable repository now.
Additionally, it's version 18.03, which doesn't suffer
any of the problems we've observed with 18.05 (edge/nightly).
We have 2 blockers that prevent us from adding support:
- the Docker CE repository does not publish a `docker-ce` package
in the `stable` channel. It's still in `edge`
(can be worked around by using `edge`, but we'd better not)
- Docker bind propagation has troubles on Docker CE 18.05,
which breaks matrix-synapse.service from starting, as it wants to do
a `:slave` mount. See https://github.com/moby/moby/issues/37032
Since cbee084ac1, this playbook supports Postgres 10.x,
but keeps existing Postgres-9.x installs on 9.x.
This playbook can now also be ran with `--tags=upgrade-postgres`
to make it upgrade from Postgres 9.x to 10.x (or other versions
in the future).
The non-working script is supposed to be fixed
by https://github.com/matrix-org/synapse/pull/2375
To have it work, we'd need an updated Docker image
of `silviof/matrix-riot-docker:latest`, which is not yet available
at the time of this commit.
Still, the previous patched synapse_port_db didn't work well either,
so it's not like we're regressing much by getting rid of it.
