- 88. #devopsdays Chicago 2015 Summary • Create a platform for docker deployments using shared and app-specific “localhost” helpers — this was ours, yours SHOULD look different — adapt to change, don’t fight it. • People don’t scale, use automation • Docker - repeatable applications (environment portable apps) • Chef - repeatable infrastructure (environment aware services) • Jenkins - repeatable releases (pipelines) • Delineate configuration concerns: • Known at Compile time — Bake into Docker image • Known at Boot time — Bake into Playbook/Launcher - parameter to Docker run • Changes Anytime — Externalize (consul K/V, etcd, zookeeper)
