Nova Resource:Wikidata-dev/wikidata-shex
This instance (wikidata-shex.wikidata-dev.eqiad.wmflabs) is a test system for the planned Wikidata Shape Expressions integration. It is managed by the members of the Wikidata ShEx hike.
Setup
The system is based on the debian-9.6-stretch image.
MediaWiki is installed via the role::labs::mediawiki_vagrant Puppet role.
To do anything Vagrant-related, you will want to SSH into the VM (ssh wikidata-shex.eqiad.wmflabs)
and then change to the Vagrant directory (cd /srv/mediawiki-vagrant).
Vagrant creates an LXC container and proxies port 8080 to it;
run vagrant ssh in the VM to get a shell inside that container.
(If that command prints an error about a Vagrant environment being required, you probably forgot the cd /srv/mediawiki-vagrant.)
In the container, MediaWiki is installed under /vagrant/mediawiki,
but modifying things there by hand is probably a bad idea, since they might get erased by Puppet.
(Note that this is a different Puppet setup than the main Cloud VPS one â this one is Vagrantâs responsibility.)
MediaWiki extensions (WikibaseSchema, ConfirmEdit, ULS, CLDR, Babel) are therefore installed via new Puppet manifests
which are defined in /vagrant/puppet/modules/local/manifests/
and loaded in /vagrant/puppet/hieradata/local.yaml;
any changes to the Puppet setup are applied by running vagrant provision in the VM (not in the container).
A Cloud VPS proxy is set up to serve the VMâs port 8080 (which, per the above, is proxied to the LXC container) at https://wikidata-shex.wmflabs.org/.
The systemd units git-update.service and git-update.timer,
defined in corresponding unit files under /etc/systemd/system/,
automatically pull the latest code every ten minutes during working hours.
To manually update the code, run sudo systemctl start git-update.
If anything went wrong during the update, you can see the output with sudo journalctl -u git-update -e -a.
(TODO: perhaps those units should be puppetized?)
The password for the MediaWiki âAdminâ user may be viewed with the command sudo cat ~root/Vagrant_MediaWiki_Password.
Dedicated accounts for all the relevant users have been created (contact the devs if more are needed).
The system cannot send email;
if you try to send an email from MediaWiki
(e.âŻg. to create an account and email the user the password),
it will be appended to the file /var/mail/vagrant inside the container.
Logging
Remember that you can always log updates in #wikimedia-cloud connect:
!log wikidata-dev wikidata-shex blah blah doing things
You can see all wikidata-shex SAL log entries.
