cloudweb1003 and cloudweb1004 host Wikitech, Horizon and toolsadmin (Striker).

As wiki hosts they are fairly non-standard: code is deployed the usual way, but X-Wikimedia-Debug does not work, login uses the developer account (LDAP) credentials, and various things might be less reliable (e.g. logging).

Connecting

Connect to cloudweb1003 over ssh by proxying through a bastion (e.g. bast1003.wikimedia.org). As with other hosts, ensure you have ProxyJump configured in .ssh/config (see Production shell access). Then connect as follows:

user@laptop:~$ ssh cloudweb1003.wikimedia.org

Note that the domain name is .wikimedia.org, not .eqiad.wmnet.

Maintenance

cloudweb1003 and cloudweb1004 are load-balanced and redundant, using LVS. To take one of them out of service for maintenance, log in and run

cloudweb1003:~$ sudo depool

After maintenance, put the host back into service:

cloudweb1003:~$ sudo pool

Logs

Horizon logs are at /var/log/apache2/horizon_*, which can be scanned for failed user logins, etc. Make sure you check both cloudweb1003 and cloudweb1003.
