AnsibleFest 2018 is a Wrap! Slides from my presentation and notes

AnsibleFest 2018 is in the books, and it was a great conference! I was able to attend the 'Contributors Summit' in Austin on Monday, and remotely Thursday, and I learned quite a bit! I also presented Make your Ansible playbooks maintainable, flexible, and scalable on both days of the conference. Slides from that session are available below, but you'll have to wait for the actual video to be uploaded to see the fun little gimmick I added for the live presentation 🙃.

Kubernetes' Complexity

Over the past month, I started rebuilding the Raspberry Pi Dramble project using Kubernetes instead of installing and configuring the LEMP stack directly on nodes via Ansible (track GitHub issues here). Along the way, I've hit tons of minor issues with the installation, and I wanted to document some of the things I think turn people away from Kubernetes early in the learning process. Kubernetes is definitely not the answer to all application hosting problems, but it is a great fit for some, and it would be a shame for someone who could really benefit from Kubernetes to be stumped and turn to some other solution that costs more in time, money, or maintenance!

Reintroducing the sanity of CM to container management

Recently, Ansible introduced Ansible Container, a tool that builds and orchestrates Docker containers.

While tools that build and orchestrate Docker containers are a dime a dozen these days (seriously... Kubernetes, Mesos, Rancher, Fleet, Swarm, Deis, Kontena, Flynn, Serf, Clocker, Paz, Docker 1.12+ built-in, not to mention dozens of PaaSes), many are built in the weirdly-isolated world of "I only manage containers, and don't manage other infrastructure tasks."

The cool thing about using Ansible to do your container builds and orchestration is that Ansible can also do your networking configuration. And your infrastructure provisioning. And your legacy infrastructure configuration. And on top of that, Ansible is, IMO, the best-in-class configuration management tool—easy for developers and sysadmins to learn and use effectively, and as efficient/terse as (but much more powerful than) shell scripts.
