This verifies that the proxy is working by accessing a
highly-available website through it. Since failure of this equates to
failures of Sentry notifications and Android mobile push
notifications, this is a paging service.
In production, the `wildcard-zulipchat.com.combined-chain.crt` file is
just a symlink to the snakeoil certificates; but we do not puppet that
symlink, which makes new hosts fail to start cleanly. Instead, point
explicitly to the snakeoil certificate, and explain why.
Redis is not nagios, and this only leads to confusion as to why there
is a nagios domain setting on frontend servers; it also leaves the
`redis0` part of the name buried in the template.
Switch to an explicit variable for the redis hostname.
This is more broadly useful than for just Kandra; provide
documentation and means to install Smokescreen for stand-alone
servers, and motivate its use somewhat more.
This is required for unattended upgrades to actually run regularly.
In some distributions, it may be found in 20auto-upgrades, but placing
it here makes it more discoverable.
We haven't actively used this plugin in years, and so it was never
converted from the 2014-era monitoring to detect the hostname.
This seems worth fixing since we may want to migrate this logic to a
more modern monitoring system, and it's helpful to have it correct.
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.
