@grkvlt Docker Cloud • Brooklyn Blueprint for Docker Cluster •
Docker Engine on Cloud VM or Bare Metal • Configuration for Host • TLS Certificates • Setup Volumes • Logging • Install SDN Agents • Manage Capacity or Headroom Copyright 2015 by Cloudsoft Corporation Limited

@grkvlt Headroom • Ensure resources available • Based on MaxContainers
strategy limit • Or Percentage Utilisation • Or CPU and RAM allocation • Scale Docker Host Cluster Automatically • Add new Docker hosts • Remove empty Docker hosts Copyright 2015 by Cloudsoft Corporation Limited

@grkvlt Docker Cloud 1. On-demand 2. Multi-Tenant 3. Hardware Independent
4. Application Level Copyright 2015 by Cloudsoft Corporation Limited

@grkvlt Clocker Features • Docker Extensions to Brooklyn –Docker Image
as First-Class Service Type –Placement Strategies for Containers –Create Docker Images and Networks • Manages Docker Engine and Swarm –Deployment and Management –Installation and Configuration –Software-Defined Networking Copyright 2015 by Cloudsoft Corporation Limited

Clocker Networking

@grkvlt Software-Defined Networking • Needed for Seamless Provisioning • Host
to Host Communication • Same LAN Segment • No Port Forwarding • Natural Application Configuration • Initial Driver was EPMD Applications • Useful for any opinionated applications Copyright 2015 by Cloudsoft Corporation Limited

@grkvlt Networking Providers • Implementation Agnostic • L2 overlay, L3
routing etc. • Similar to Hypervisor in Clouds • Generic Interfaces • Host Component • Service Component (or Endpoint) • Same idea as Docker Network Plugins Copyright 2015 by Cloudsoft Corporation Limited

@grkvlt Networking Capabilities • Attach Containers to Networks • Create
Networks as Required • Also Attach to VMs and Metal • Provide Multiple Networks • Per-Application or Shared • Segmented Private Address Space • Docker Port Forwarding for Ingress Copyright 2015 by Cloudsoft Corporation Limited

@grkvlt Network Provisioning • Minimal (Zero!) Configuration • Use Sensible
Defaults • Allows SDN or Cloud Specific Configuration • Allocate Address Space on Demand • IP Pool Controlled by Clocker -‐ type: brooklyn.networking.VirtualNetwork networkId: database-‐net cidr: 192.168.34.0/24 gateway: 192.168.34.1 dnsServers: -‐ $brooklyn:entity("bind-‐server").attributeWhenReady("host.address") addIptablesRules: true -‐ type: brooklyn.networking.OpenStackVirtualNetwork networkId: couchbase-‐net Copyright 2015 by Cloudsoft Corporation Limited

@grkvlt Clocker Networking Container Host SDN Bridge Container Internet SDN
Gateway Copyright 2015 by Cloudsoft Corporation Limited

@grkvlt Metaswitch Project Calico • SDN for Bare Metal, VMs
and Containers • Layer 3 • Uses OS IP routing and forwarding • Configuration in an etcd Cluster • Version 0.4.9 in Clocker • 0.6.0 with libnetwork when Docker stable • Spans VMs and Containers • OpenStack Neutron network driver Copyright 2015 by Cloudsoft Corporation Limited

@grkvlt Networking Capabilities • Wide Area and Multi Region SDN
• VPN or IPIP and NAT configuration • Cross Platform SDN • Both VMs and Containers on one VLAN • Name Resolution and Service Discovery • Contributing to Weave DNS for orchestration • Use traditional external BIND service entity • Brooklyn can inject correct endpoint address Copyright 2015 by Cloudsoft Corporation Limited
