= static mirroring

The static mirroring system mirrors //components//, i.e. directory trees from
their individual //source// hosts via //static-master// hosts to the
//static-mirrors//.

The static-master can be configured per source.  The mirrors are the same set
for all components.

== Adding a new static component

Using already configured source and master hosts.

* Pick a component name, e.g., {{{debaday.debian.net}}}

* Pick/Learn source host, pick a master, and add to {{{dsa-puppet/modules/roles/files/static-mirroring/static-components.conf}}}:
{{{
	# <master>              <service>                       <source host>                   <directory>                             <extra push hosts, comma separated>
	dillon.debian.org       debaday.debian.net              dillon.debian.org               /srv/debaday.debian.net/htdocs
}}}

* Give sudo to run the right {{{static-update-component}}} to the appropriate group:
{{{
	/usr/sbin/visudo -f dsa-puppet/modules/sudo/files/sudoer
}}}
and add something like
{{{
	lucas           dillon=(staticsync)             NOPASSWD: /usr/local/bin/static-update-component debaday.debian.net
}}}

* Add the vhost config on mirrors:
{{{
	vi dsa-puppet/modules/roles/templates/static-mirroring/vhost/static-vhosts-simple.erb
}}}

* run puppet on the master, the source, and all the mirrors.  Check {{{dsa-puppet/hieradata/common.yaml}}}.

== Adding a mirror

Note:  This might temporarily break apache on the new mirror host.

* Add host to {{{static_mirror}}} and {{{static_mirror_nopush}}} in {{{hieradata/common.yaml}}}.
* Add {{{staticsync}}} group to host's {{{allowedGroups}}} attribute in ldap.
* Run puppet twice on new static mirror once staticsync exists.
* Run puppet on static masters.
* On the static mirror: {{{install -d -o staticsync -g staticsync -m 02755 /srv/static.debian.org}}}.
* Run the command from {{{/etc/cron.d/puppet-static-mirror}}} on the mirror.
* Make sure apache works on the mirror.  This might require deploying SSL keys.
* Remove mirror from {{{static_mirror_nopush}}}.
* Run puppet on static masters.
* Rotate mirror.
