19. How can I run Dockerized applications?

20. Extend the deployment API to run a Docker image on
our native Garden-Linux container backend.
cf push APP DOCKER-REPO
POST /containers
{
"bind_mounts": [],
"grace_time": 1200,
"handle": 'user-supplied-handle',
"network": 'network',
"rootfs": 'rootfs',
"properties": [],
"env": [] }
200 Ok
{ handle: 'handle-of-created-container' }
Deploy the container image root
filesystem.
Attempt to parse container image
metadata for memory, disk, user,
launch command and port.

25. How can I run workers and tasks?

26. New Workload Types
Tasks
A single unit of work
Runs at most once
N long running instances
Distributed across cells for HA
Monitored and restarted
Long Running
Processes

27. RunAction: run process in container
DownloadAction: fetches and extract archive
UploadAction: POST file from container to URL
ParallelAction: run multiple actions in parallel
SerialAction: runs multiple actions in order
EmitProgressAction: wraps action and logs progress
TimeoutAction: wrap action and fail if timed out
TryAction: wrap action and ignore errors

30. How can I develop Cloud Foundry
applications on my local machine?

32. • Single-tenant
• Everyone is ‘cluster root’
• Wide-open networking
• Not all components are HA
• Red-black upgrades
• No data services
• Multi-tenancy with resource quotas
• Role-based access control
• Application security groups
• Highly-available components
• Zero-downtime, rolling upgrades
• Backing data service orchestration
Repackaging the Runtime
Production usage
with 20+ VMs
Local
development on a
single host

34. 10,000 “real app” container instances (100 per cell)
4,000 concurrent tasks
4,000-instance LRPs
Scalability
