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
