In this episode, we talk about:

• Options about how to change your Windows password without logging into a Windows Machine:
  • Join Linux machine to the AD
  • smbpasswd
  • pwm
  • passcore
  • Some other options (uninvestigated)
• 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
    • Usually run on the machine following the build.
    • Test Kitchen (now just called kitchen.ci) lets you run inspec on a virtual machine in an automated way.
  • 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
