mwdebug

As part of MediaWiki On Kubernetes, two mw-debug deployments exist (one in each datacenter). These deployments can be reached via the browser through the k8s-mwdebug option for WikimediaDebug (for the current datacenter), or k8s-mwdebug-eqiad or k8s-mwdebug-codfw in the rare case that you want a particular one.

mwdebug hosts are a small cluster of application servers set aside for use with WikimediaDebug.

The servers run on shared Ganeti hardware rather than baremetal and have a few additional packages installed to aid in debugging (such as php-tideways). We currently have:

• (削除) mwdebug1001.eqiad: Ad-hoc testing (削除ここまで)
• (削除) mwdebug1002.eqiad: Stage during deployment for Eqiad. (削除ここまで)
• (削除) mwdebug2001.codfw: Ad-hoc testing. (削除ここまで)
• (削除) mwdebug2002.codfw: Stage during deployment for Codfw. (削除ここまで)
