This changes the behavior of
`matrix_playbook_migration_matrix_nginx_proxy_uninstallation_enabled`
and is against what we initially described in the changelog entry,
but I've discovered some problems when the `matrix-nginx-proxy` service
and container remain running. They need to go.
This allows people to not include the `matrix-conduit` or
`matrix-dendrite` roles in their custom playbook (based on our roles)
and still not have the playbook choke on variables from these roles
missing.
For getting rid of the `matrix-synapse` role in a similar way,
more work is likely necessary.
After some checking, it seems like there's `/_synapse/client/oidc`,
but no such thing as `/_synapse/oidc`.
I'm not sure why we've been reverse-proxying these paths for so long
(even in as far back as the `matrix-nginx-proxy` days), but it's time we
put a stop to it.
The OIDC docs have been simplified. There's no need to ask people to
expose the useless `/_synapse/oidc` endpoint. OIDC requires
`/_synapse/client/oidc` and `/_synapse/client` is exposed by default
already.
Traefik also serves an internal entrypoint that all addon services
(bridges, bots, etc.) depend on, so it makes sense to have it be
available early on. It is injected as a systemd `required` dependency
for all services, so it would have been pulled earlier anyway (despite
the priority). Nevertheless, it's better to make the playbook-defined
priotities for services match, so that services are explicitly asked to
start in a more correct order.
With these changes in place now, all "start service" tasks executed by
Ansible cause a "change", indicating that all these services are started
in the correct order and none of them is unintentionally started as a
dependency for another.
Issues and Pull Requests were not migrated to the new
organization/repository, so `matrix-org/synapse/pull` and
`matrix-org/synapse/issues` references were kept as-is.
`matrix-org/synapse-s3-storage-provider` references were also kept,
as that module still continues living under the `matrix-org` organization.
This patch mainly aims to change documentation-related things, not actual
usage in full yet. For polish that, another more comprehensive patch is coming later.
