- 3. Some things of note Lots of Compute Power Containers (probably SaaS) Multi-tenant IP-per-container Individual Firewalls ZFS Snapshot/rollback containers and volumes HA Proxy Load balancing SSL HTTP2
- 4. FROM debian Dynamic/Static COPY ourstuff COPY startup.sh + Finding config from KV Store + DNS stunts + Mapping volumes for test/prod + Other stuff, I’m sure
- 5. Ends up in a mess :( Dynamic and static content end up mashed together Environment variables are a terrible interface Another set of variables for orchestrator (test/prod volume mappings, ports, ip’s) Looks like something that can go wrong so it will.
- 6. Tiny Apps Application Only (no boot code) Manage with systemd Command line help Generate SSL keys Pre-boot messing with files Volume mapping Attach tunnels
- 11. Containers Running as part of a different app I am the database postgresql We are the Webapp rails railsrails
- 12. ZFS is your friend
- 13. SSH is your friend, too We are the Webapp rails
- 14. Even Docs
- 15. CLI Also tools for: Volumes Domain names Resources Acct Backup Image Caching

Notas do Editor
- Docker containers Started with, Mesos, SmartOS Metal or AWS Getting control over what happens
- That’s all the stuff you don’t want to change More to the point it’s horrible to debug
- ie the actual code and code associated with instantiating
- Template is baked in
- No need to run SSH server, map ports, work out which node it’s on etc. etc. All part of making it easy to work with. You can use Python as a repl, too
