The only relevant changes are `PasswordAuthentication no` (which
is now the default) and `MaxStartups 40:50:60` (which is now
unneccesary due to autossh tunnels.
This was changed midway through the implementation, from reading it
from `zulip-secrets.conf`, and a couple locations still reference the
secrets path.
fcf096c52e removed the callsite which would have notified this
contact. Note that the source config file was presumably installed via the
python-zulip-api package.
The `unless` step errors out if /usr/bin/psql does not exist at
first evaluation time -- protect that with a `test -f` check, and
protect the actual `createuser` with a dependency on `postgresql-client`.
To work around `Zulip::Safepackage` not actually being safe to
instantiate more than once, we move the instantiation of
`Package[postgresql-client]` into a class which can be safely
included one or more times.
Since backups may now taken on arbitrary hosts, we need a blackbox
monitor that _some_ backup was produced.
Add a Prometheus exporter which calls `wal-g backup-list` and reports
statistics about the backups.
This could be extended to include `wal-g wal-verify`, but that
requires a connection to the PostgreSQL server.
7c023042cf moved the logrotate configuration to being a templated
file, from a static file, but missed that the static file was still
referenced from `zulip_ops::app_frontend`; it only updated
`zulip::profile::app_frontend`. This caused errors in applying puppet
on any `zulip_ops::app_frontend` host.
Prior to 7c023042cf, the Puppet role was identical between those two
classes; deduplicate the rule by moving the updated template
definition into `zulip::app_frontend_base` which is common to those
two classes and not used in any other classes.
Following zulip/python-zulip-api/pull/758/, we're no longer using
python-zephyr, and don't need to build it from source. Additionally,
we no longer need to build a forked Zephyr package, since ZLoadSession
and ZDumpSession were merged in
e6a545e759.
To not change the `supervisor.conf` file, which requires a restart of
supervisor (and thus all services running under it, which is extremely
disruptive) we carefully leave the contents unchanged for most
installs, and append a new piece to the file, only for the zmirror
configuration, using `concat`.
