DNS implementation proposal
by Arturo Borrero Gonzalez 31 Jan '20

31 Jan '20

Hi there, TL;DR: I brain-dumped a wiki page here: https://wikitech.wikimedia.org/wiki/Wikimedia_Cloud_Services_team/Enhanceme… I hope I managed to write my ideas clear enough. Points for debate: * ownership of designate domains (cloudinfra vs wmflabsdotorg vs admin vs ..) * service name of designate (ns0.openstack.eqiad1.wikimediacloud.org??) * delegations, per-project subdomains etc * all the details about the wmcloud.org subdomain Hey Arturo, why this now?? I've been doing several operations to be able to set up a bastion and puppetmaster in codfw1dev like we do in eqiad1. While at it, instead of setting this up with the legacy domains, I step forward and have been playing with the new domains. All this kung-fu allowed me to review the setup and identify several points where we could introduce a bit more consistency and robustness. The changes I've been doing in codfw1dev will eventually land in eqiad1, so double win! Some new stuff to try related to this follows. * add this to your .ssh/config file: === 8< === Match user root host *.codfw1dev.wikimedia.cloud User root IdentityFile ~/.ssh/root_key IdentitiesOnly yes ForwardAgent no ProxyCommand ssh -i ~/.ssh/root_key -a -W %h:%p root(a)bastion-codfw1dev-01.codfw1dev.wmcloud.org === 8< === * try SSH! user@laptop:~$ ssh root(a)puppetmaster-01.cloudinfra-codfw1dev.codfw1dev.wikimedia.cloud * this means we have the following 2 domains working: - puppetmaster-01.cloudinfra-codfw1dev.codfw1dev.wikimedia.cloud - bastion-codfw1dev-01.codfw1dev.wmcloud.org Comments welcome. regards! -- Arturo Borrero Gonzalez SRE / Wikimedia Cloud Services Wikimedia Foundation

New Phabricator board for tracking WMCS hardware issues
by Bryan Davis 09 Jan '20

09 Jan '20

I was trying to figure out how to keep better track of hardware things and realized that one thing we had not tried yet is a dedicated workboard. I asked on irc and Brooke and Jason didn't immediately think it was a horrible idea, so I moved ahead with an experiment: https://phabricator.wikimedia.org/project/view/4482/ You can add things with the #wmcs-hardware tag. Y'all can also mess with columns and ordering, but maybe check in with Jason before taking any really radical actions as I expect he will be one of the main consumers of this board as he interfaces with the DCOps folks. One possibly surprising thing when using the new tag: I made #wmcs-hardware a "milestone" of #cloud-services-team. This means that when you add #wmcs-hardware Phabricator will remove #cloud-services-team and of it's other milestones. #wmcs-kanban is also a milestone, so a hardware task can be in one board or the other, but not both! Let's revisit this in our Q3 process retro and decide if we will keep this new board of archive it and try something else.
