Debian Stretch was officially released on Saturday, and I've built a new Stretch base image for VPS use in the WMF cloud. All projects should now see an image type of 'debian-9.0-stretch' available when creating new instances.
Back in the dark ages of Labs, all instance puppet configuration was handled using the puppet ldap backend. Each instance had a big record in ldap that handled DNS, puppet classes, puppet variables, etc. It was a bit clunky, but this monolithic setup allowed @yuvipanda to throw together a simple but very useful tool, 'watroles'. Watroles answered two questions:
The first very visible step in the plan to rename things away from the term 'labs' happened around 2017-06-05 15:00Z when IRC admins made the #wikimedia-labs irc channel on Freenode invite-only and setup an automatic redirect to the new #wikimedia-cloud channel.
When @Ryan_Lane first built OpenStackManager and Wikitech, one of the first features he added was an interface to setup project-wide sudo policies via ldap.
For nearly a year, Horizon has supported instance management. It is altogether a better tool than the Special:NovaInstance page on Wikitech -- Horizon provides more useful status information for VMs, and has much better configuration management (for example changing security groups for already-running instances.)
I've just installed a new public base image, ' debian-9.0-stretch (experimental)' and made it available for all projects. It should appear in the standard 'Source' UI in Horizon any time you create a new VM.
Andrew will be upgrading our Openstack install from version 'Kilo' to version 'Liberty' on Tuesday the 2nd. The upgrade is scheduled to take up to three hours. Here's what to expect:
If you are exclusively a user of tool labs, you can ignore this post. If you use or administer another labs project, this REQUIRES ACTION ON YOUR PART.
The Kubernetes ('k8s') backend for Tool Labs webservices is open to
beta testers from the community as a replacment for Grid Engine
horizon (OpenStack Dashboard) is the canonical implementation of OpenStack’s Dashboard, which provides a web based user interface to OpenStack services.
tools-login.wmflabs.org is on a new bastion host with twice
the RAM and CPU of the old one. This should hopefully provide a better
bandaid against it getting overloaded up. More discussion about a
longer term solution at https://phabricator.wikimedia.org/T131541
On Tuesday, 2016-04-05, we'll be upgrading Kubernetes to 1.2 and using
a different deployment method as well. While this should have no user
facing impact (ideally!) the following things might be flaky for a
period of time on that day:
