Single Host!
Containers!
• Easy to use !• Single Purpose environment!!
• But: non trivial once you move beyond a single host and applications need networking and other tooling!
Multi Host!
Weave!• What? Portable application clusters made easy!
• How? Service discovery & address automation via a secure, application orientated virtual container network!
• Write the application and get the networking to do what you need not vice versa!
• Minimum configuration, it just works !
• Containers do not require specialist knowledge of other containers to connect to each other!
Weave Info!• Launched Sept 2014!

Weave Run!
Weave Run!• Service Discovery, Automatic IP Address Allocation
and Management, Load Balancing and DNS for containers!
• All part of Weave!
• nothing to configure!
• nothing to maintain!
• no change request to submit when you need a new name…. !
Weave Run!• Just launch your containers with a hostname using
regular docker commands!
• Weaves functionality will do the rest!
• Application is addressable by a known hostname!
• Weave can do simple round robin load balancing efficiently as you are in a constrained network!
• Easy to query via dig for information that load balancers or other tools may need!
In Practice?!
• Install Weave!
sudo curl -L git.io/weave -o /usr/local/bin/weave sudo chmod a+x /usr/local/bin/weave!
• Launch Weave!
"weave launch [-initpeercount x] !
In Practice?!
"eval $(weave proxy-env) "!
"docker run –d –h foo.weave.local your/container !
"docker run –d –h bar.weave.local my/container!
Upcoming!• Fast Data Path 1.0!
• In kernel data path!
