You just start with the golang base and go get /kobolog/gorb. The Dockerfile for the GORB container is super simple because it’s a Go app.

In that situation, the MacVLAN Docker network plugin enables you to give containers their own MAC addresses to utilize the fastest IPVS mode by forwarding at L2. Sibiryov pointed out that small companies don’t necessarily need IPVS, but it does become useful once traffic scales.
GORB Docker Link Container to automatically detect Docker containers and route to themĭocker + GORB + MacVLAN network plugin + IPVS DR mode = dream setup REST API Daemon Container to control IPVS It’s still pretty beta, but it looks really cool. It’s a REST API for IPVS inside a Docker Container to provide IPVS routing for Docker. To make IPVS easier to use, he wrote GORB. But there are other benefits:Īs Sibiryov said, “Linux kernel things are crazy magical tools from space.” So how do you put something like that to good use? But if NGINX/HAProxy, hipache, and Vulcan work fine, why would you need IPVS? Sibiryov said that if you have more than one instance of an app, you need load balancing. HAProxy and MySQL proxy were around 60 percent of its speed. In testing, IPVS’ performance was nearly the same TPS as a normal connection. Rewrites DST IP, uses the same L4 and behaves like a NAT, rewriting the ip packets and forwarding request and response traffic. The response skips the load balancer, so only the request goes through IPVS.ĭNAT.
Encapsulates IP and is routable anywhere. IPVS forwards traffic from clients to back-ends, meaning you can load balance anything, even DNS! Modes it can use include: It’s not a proxy - it’s a forwarder that runs on Layer 4. Other features include NAT, tunneling, and direct routing. It supports TCP, SCTP, and UDP and can achieve incredibly fast speeds, often within 5 percent of direct connection speeds. To be precise, IPVS (IP Virtual Server) has been in the kernel for 15 years, and it’s based on netfilter.

Yesterday at DockerCon Europe, Andrey Sibiryov, a senior engineer at Uber Technologies, demonstrated how to improve load-balancing performance using an open-source technology that’s been part of the Linux kernel for more than a decade - IPVS.Īndrey Sibiryov discusses IPVS at DockerCon Europe.
