Admin Admin Podcast #074 Show Notes – Devops is not a dirty word

Sadly, we’ve no Al this time, it’s just Jon and Jerry.

Want to join the community talking about this podcast on Telegram? Join us!

In this episode, we talk about:

  • Options about how to change your Windows password without logging into a Windows Machine:
  • What “is” Active Directory – it’s not open source LDAP and Kerberos, but an implementation of the open protoocol.
  • We want to do more Q&A – email us!
  • We talk about TDD and Infrastructure as Code
    • inspec
    • rspec
    • Noted that you sometimes need to mock up the connections to external services, e.g. you can’t always “mock” connecting to an IRC server.
  • Mentioned IRC, SMTP, CI/CD, Vagrant
  • DevOps is a Buzzword (so was Cloud!) but it isn’t a dirty word!
    • Jon and Jerry disagree on terminology! Jon thinks DevOps is a culture not tooling. Jerry thinks you can have tooling because the tools didn’t exist, or weren’t in mainstream use a few years ago.
    • Config Management Tools are mentioned (things like Ansible, Chef, Puppet, Salt and more…)
    • Jon talks about silo‘ing that happens in large enterprises, and then explains how DevOps aims to change that behaviour.
    • We talk about multi-disciplinary teams, and how the team members in those teams don’t lose their own unique skills. We talk about how Infrastructure as Code massively supports that requirement.
    • Jon mentions Smoke Tests, Jerry mentions Disposable Infrastructure. Jon mentions Geek Code, Failing Fast, chaos monkey and Game Days.
    • We mention change management rituals (including ITSM toolsets) and why “don’t push to prod on a friday” isn’t a good idea (in certain cases) and GitOps.
  • Synchronising between a “Live” and “Dev” wordpress environment – audience, we need your help! 🙂
    • Mentioned LAMP Stack and Restic
    • Taking Database Dump and manipulating the resulting data.
    • Suggested using an ansible playbook, or using MySQL Views. Neither are suitable right now!
  • Mentioned OggCamp – and that they’re looking for talk submissions for the scheduled track at the moment.
  • Mentioned FossTalk Live
