πŸ’» SSH keys generation[edit]

You need two SSH keys (both should have a memorable passphrase):

Wikimedia Developer Account SSH key #[edit]

ssh-keygen -f ~/.ssh/id_ed25519.wmfdev -t ed25519 -C "your_email@youremail.com"
  • This creates two files in ~/.ssh:
    • id_ed25519.wmfdev - Wikimedia developer account private key NEVER SHARE THIS
    • id_ed25519.wmfdev.pub - Wikimedia developer account public key OK TO SHARE/post publicly

Wikimedia Production Access SSH key #[edit]

  • Used ONLY for access to production machines via ssh
    • For example, to deploy code to production, you'll use this key
  • For your production account use:
ssh-keygen -f ~/.ssh/id_ed25519.wmfprod -t ed25519 -C "your_email@youremail.com"
  • This creates two files in ~/.ssh
    • id_ed25519.wmfprod - Wikimedia production account private key NEVER SHARE THIS
    • id_ed25519.wmfprod.pub - Wikimedia production account public key OK TO SHARE/post publicly

We have a recommended .ssh/config to use.

πŸ” GPG key[edit]

  • Run gpg2 --full-generate-key and follow the prompts. Defaults are usually good, but use a 4096 bit length.
  • Thengpg2 --keyserver pool.sks-keyservers.net --send-key uploads public key to key server
  • Submit a patch for our PGP public key repo including only your public key (gpg --export-options no-export-clean,no-export-minimal --armor --export YOU@EMAIL > your_name.asc)
  • Reach out to Tyler to see about getting it signed. Requires two signatures.

πŸ‘₯ People to meet and things to do with them[edit]

The goal is to meet your team mates and learn how the team fits together. Hopefully you'll talk to everyone on the team one on one for about thirty minutes over the first week or two. Bookmark the contact list on officewiki β€” you will use it a lotΒ :)

πŸ“ First day[edit]

  • Tyler Cipriani (thcipriani), manager of the Release Engineering team. He is normally in the US Mountain timezone.
    • Tell him everything is going great and that the instructions are easy to follow but you are still overwhelmed by the reading you have to do.
    • Tell him that you found some errors in the instruction and fixed the template. :P
    • Ask him to give you an overview of how the foundation is organized, what teams do what, and all that.
    • Make sure he adds you to any relevant team meetings.
    • He'll want to talk to you one on one a few times in the first week.

First couple of weeks[edit]

Meet the whole team:

  • Ahmon Dancy (dancy) - Pacific timezone
    • Ask him about MediaWiki on Kubernetes, Emacs, databases, or Common Lisp.
  • Antoine Musso (hashar) - Central European timezone
    • Ask him to tell you the origin story of our Continuous Integration infrastructure, including Beta Cluster.
    • Ask him all about French cooking and why it's the best country to live in.
  • Brennen Bearnes (brennen) - Mountain timezone
    • Ask him about error logs, Vim, docker-compose, or GitLab.
  • Dan Duvall (marxarelli) - Pacific timezone
    • Ask him about the Deployment Pipeline.
    • Ask him about maintaining the infrastructure for a website that got 99% of it's traffic in one month.
  • Jeena Huneidi
    • Ask her about Kubernetes, docker-compose, tea, or ponies.
  • Jaime Nuche
