Workshop Descriptions

• Docker has revolutionized virtualization by abstarcting some ~15 years old Kernel tools, allowing developers, system admins and Devops to easily package and deliver application-in-containers without worring about the underlying infrastructure and application dependencies when moving from one environment to another.

Along the way they have been using some basic linux netowrking tools ( and now windows ) that enabled container netowrking.

This workshop will intreduce general netowrking concepts, tools and docker specific netowrking model and its implementation.

Participants Will

1. Understand basic networking concepts by using various tools such as tcpdump, ip command etc.
2. Understand the CNM ( container networking model ).
3. Understand single host container networking ( bridge driver ) and multi-host container networking ( overlay driver )

Workshop agenda

The workshop has 2 part

Part 1 - 90 minutes

• linux networking:
  • Networking models.
  • NIC
  • Routing
  • iptables
  • namespace and linux bridge
  • name resolution
  • ipvs

Part 2 - 90 minutes

• docker netowrk background:
  • history
  • componenets
• docker network subcommand.
• docker network drivers:
  • bridge
  • overlay

Who this workshop is for

• This workshop is targeted at users who already know the basics of Docker and linux networking, That want to know how this magic of container networking works under-the-hood

Knowladge Prerequisites

• Participants are expected to have expiriance with docker.
• Although I will try to cover all that is needed from networking POV, participants who have basic knowladge in the OSI or TCP/IP model, will find the workshop musch easier to follow.

Hardware Prerequisites

• This wordshop was built on MAC Sierra, with Docker 1.12 ( tested on 1.13 ).
• Other OS ( Windows, Ubuntu etc .. ) could also benefit from both part of the Workshop but some commands will just not work.

Where to start?
