NETWORKING 1.9.0- Notes

LIBNETWORK

◼Open Sourced in April

◼Over 500 Pull Requests

◼Over 500 GitHub Stars

◼Windows and FreeBSD ports in progress

Defer to Driver

Overlay Driver

• Creates a separate network namespace for every network- Facilitates overlapping IP address space across networks

• Creates a Linux Bridge and VXLAN tunnels to every other discovered host

• Creates a veth pair for each endpoint- One end is attached to the bridge- The other appears as eth0 inside the container

• Network namespace connected to host network using NAT- Facilitates exiting the overlay network at every host(for external

connectivity)

Networking in Single Host - Notes

◼3 local network by default: Null, Host, Bridge ( like as: Docker0 ) - you cannot delete them

◼2 Network Drivers: Bridge & overlay (need a cluster management)

◼Can assign multiple network to a container

◼Legacy links: docker run --link is not supported within a user-defined

bridge network. (only support with Bridge and Docker0)

Networking in Multiple Host - NotesPrerequisites:

◼the Docker hosts with a 3.16 kernel version or higher

◼Access to a key-value store. Docker supports Consul, Etcd, and ZooKeeper (Distributed store) key-value stores.

◼A cluster of hosts with connectivity to the key-value store.

◼A properly configured Engine daemon on each host in the cluster.

Networking in Multiple Host - Notes

◼Additionally, containers connected to the multi-host network are automatically connected to the docker_gwbridge network.

◼docker_gwbridge allows the containers to have external connectivity outside of their cluster.

Persitent Storage - Notes

Persitent Storage - NotesWhat is new in 1.9 ?

◼Made the volume feature better and easier

◼Intergrating with swarm (even works - just to try it)

◼More storage drivers from third party:

◼Flocker

◼ Blockbridge, Ceph, ClusterHQ, EMC and Portworx
