Earlier today I presented orchestrator on DB AMA. Thank you to the organizers Morgan Tocker, Liz van Dijk and Frédéric Descamps for hosting me, and thank you to all who participated!
This was a no-slides, all command-line walkthrough of some of orchestrator‘s capabilities, highlighting refactoring, topology analysis, takeovers and failovers, and discussing a bit of scripting and HTTP API tips.
The recording is available on YouTube (also embedded on https://dbama.now.sh/#history).
To present orchestrator, I used the new shiny docker CI environment; it’s a single docker image running orchestrator, a 4-node MySQL replication topology (courtesy dbdeployer), heartbeat injection, Consul, consul-template and HAProxy. You can run it, too! Just clone the orchestrator repo, then run:
./script/dock system
From there, you may follow the same playbook I used in the presentation, available as orchestrator-demo-playbook.sh.
Hope you find the presentation and the playbook to be useful resources.
