This provides a single reference point for all zulip.conf settings;
these mostly link out to the more complete documentation about each
setting, elsewhere.
Fixes#12490.
There is only one PostgreSQL database; the "appdb" is irrelevant.
Also use "postgresql," as it is the name of the software, whereas
"postgres" the name of the binary and colloquial name. This is minor
cleanup, but enabled by the other renames in the previous commit.
This moves the puppet configuration closer to the "roles and profiles
method"[1] which is suggested for organizing puppet classes. Notably,
here it makes clear which classes are meant to be able to stand alone
as deployments.
Shims are left behind at the previous names, for compatibility with
existing `zulip.conf` files when upgrading.

This also removes direct includes of `zulip::common`, making
`zulip::base` gatekeep the inclusion of it. This helps enforce that
any top-level deploy only needs include a single class, and that any
configuration which is not meant to be deployed by itself will not
apply, due to lack of `zulip::common` include.
The following commit will better differentiate these top-level deploys
by moving them into a subdirectory.
Restarting servers is what can cause service interruptions, and
increase risk. Add all of the servers that we use to the list of
ignored packages, and uncomment the default allowed-origins in order
to enable unattended upgrades.
d2aa81858c replaced the `apt::source` to set up debathena with
`Exec['setup-apt-repo-debathena']`, but mistakenly left the
`apt::source` in place in `zmirror` (but not `zmirror_personals`).
The `apt::source` resource type was later removed in c9d54f7854,
making the manifest to apply on `zmirror`.
Remove the broken and unnecessary `apt::source` resource.
This property is not related to the base zulip install; move it to
zulip::postgres_common, which is already used as a namespace for
various postgres variables.
There was likely more dependency complexity prior to 97766102df, but
there is now no reason to require that consumers explicitly include
zulip::apt_repository.
Use https://github.com/stripe/smokescreen to provide a server for an
outgoing proxy, run under supervisor. This will allow centralized
blocking of internal metadata IPs, localhost, and so forth, as well as
providing default request timeouts (10s by default).
We should eventually add templating for the set of hosts here, but
it's worth merging this change to remove the deleted hostname and
replace it with the current one.
Disabled on webservers in 047817b6b0, it has since lingered in
configuration, as well as running (to no effect) every minute on the
loadbalancer.
Remove the vestiges of its configuration.
This banner shows on lb1, advertising itself as lb0. There is no
compelling reason for a custom motd, especially one which needs to
be reconfigured for each host.
Since this was using repead individual get() calls previously, it
could not be monitored for having a consumer. Add it in, by marking
it of queue type "consumer" (the default), and adding Nagios lines for
it.
Also adjust missedmessage_emails to be monitored; it stopped using
LoopQueueProcessingWorker in 5cec566cb9, but was never added back
into the set of monitored consumers.
The rabbitmq cron jobs exist in order to call rabbitmqctl as root and
write the output to files that nagios can consume, since nagios is not
allowed to run rabbitmqctl.
In systems which do not have nagios configured, these every-minute
cron jobs add non-insignificant load, to no effect. Move their
installation into `zulip_ops`. In doing so, also combine the cron.d
files into a single file; this allows us to `ensure => absent` the old
filenames, removing them from existing systems. Leave the resulting
combined cron.d file in `zulip`, since it is still of general utility
and note.
7d4a370a57 attempted to move the replication check to on the
PostgreSQL hosts. While it updated the _check_ to assume it was
running and talking to a local PostgreSQL instance, the configuration
and installation for the check were not updated. As such, the check
ran on the nagios host for each DB host, and produced no output.
Start distributing the check to all apopdb hosts, and configure nagios
to use the SSH tunnel to get there.
wal-g was used in `puppet/zulip` by env-wal-g, but only installed in
`puppet/zulip_ops`.
Merge all of the dependencies of doing backups using wal-g (wal-g
installation, the pg_backup_and_purge job, the nagios plugin that
verifies it happens) into a common base class in `puppet/zulip`, since
it is generally useful.
