An unreservedly technical presentation on the 20ft PaaS.

1. What is 20ft?

2. A toolkit,
As simple as possible,
For making apps with containers.
In a specific
location
Lots of Compute Power
Containers
Tiny Apps
that tell it
what to do

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

7. Simplest. SDK. Ever.

8. Pre-boot configuration

10. Connecting Containers

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

16. Free Code (BSD)
github.com/20ft
SDK
CLI
Images
Messaging Library
AWS abstractions
SQL async
