Alex Vandiver 6ee74b3433 puppet: Check health of APT repository. 2021-03-23 19:27:42 -07:00
Alex Vandiver c01345d20c puppet: Add nagios check for long-lived certs that do not auto-renew. 2021-03-23 19:27:27 -07:00
Alex Vandiver 9ea86c861b puppet: Add a nagios alert configuration for smokescreen.
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.

Alex Vandiver 06c07109e4 puppet: Add missing semicolons left off in ba3b88c81b. 2021-03-12 15:48:53 -08:00
Alex Vandiver ba3b88c81b puppet: Explicitly use the snakeoil certificates for nginx.
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.

Alex Vandiver 306bf930f5 puppet: Add a warning if ksplice is enabled but has no key set. 2021-03-10 17:57:20 -08:00
Alex Vandiver a215c83c2d puppet: Switch to more explicit variable rather than reuse a nagios one.
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.

Alex Vandiver a5b29398fc puppet: Only install ksplice uptrack if there is an access key. 2021-03-10 11:44:11 -08:00
Alex Vandiver d938dd9d4a puppet: Document smokescreen installation, and move to puppet/zulip/.
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.

Alex Vandiver a759d26a32 puppet: Make ksplice config not world-readable, use 'adm' group.
This matches the configuration that ksplice itself creates the file
and directory with.

Tim Abbott 957c16aa77 nagios: Tweak prod load monitoring parameters.
Ultimately this monitoring isn't that helpful, but we're mainly
interested in when it spikes to very high numbers.

Alex Vandiver 173d2dec3d puppet: Check in defensive restart-camo cron job.
This was found on lb1; add it to the camo install on smokescreen.

Alex Vandiver 0b736ef4cf puppet: Remove puppet_ops configuration for separate loadbalancer host. 2021-02-22 16:05:13 -08:00
Alex Vandiver e30b524896 iptables: Limit smokescreen port 4750, add camo port.
Limit incoming connections to port 4750 to only the smokescreen host,
and also allow access to the Camo server on that host, on port 9292.

Alex Vandiver 29f60bad20 smokescreen: Put the version into the supervisorctl command.
This makes it reload correctly if the version is changed.

Alex Vandiver 559cdf7317 puppet: Set APT::Periodic::Unattended-Upgrade in apt config.
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.

Tim Abbott fd8504e06b munin: Update to use NAGIOS_BOT_HOST.
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.

Alex Vandiver c2526844e9 worker: Remove SignupWorker and friends.
ZULIP_FRIENDS_LIST_ID and MAILCHIMP_API_KEY are not currently used in
production.

This removes the unused 'signups' queue and worker.

Alex Vandiver 90ca06d873 puppet: Allow unattended upgrades of -updates in addition to -security.
This ensures that software will be fully up-to-date, not just with
security patches.

Tim Abbott 494a685827 puppet: Fix typo in name of missedmessage_emails consumer.

Tim Abbott ab3cb2b3bf puppet: Fix internal redis puppet configuration.
The inherits rule is required for overriding existing configuration
files; while the `::profile` piece was missed in the recent ::profile
migration.

Alex Vandiver a155430eb5 docs: Document all zulip.conf settings.
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.

Alex Vandiver d24c571bab puppet: Automatically back up the database if we have the secrets.

Alex Vandiver 188af57296 puppet: Rename postgres_appdb to postgresql.
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.

Alex Vandiver c2185a81d6 puppet: Move top-level zulip deployments into "profile" directory.
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.

Alex Vandiver 27cfb14d92 puppet: Only include zulip::base for top-level deploys.
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.

Alex Vandiver c296b5d819 puppet: Allow unattended-upgrades for all but servers.
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.

Alex Vandiver a7d1fd9ffb puppet: Remove non-working apt::source.
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.

Alex Vandiver 48e06c25ba puppet: Switch nagios SSH checks to id_ed25519 key.

will be removed in a future release.

Alex Vandiver 0ea20bd7d8 puppet: Move postgres_version into postgres_common.
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.

Alex Vandiver 50e9e2ed20 puppet: Make zulip::base include zulip::apt_repository.
There was likely more dependency complexity prior to 97766102df, but
there is now no reason to require that consumers explicitly include
zulip::apt_repository.
