# ipvs - networking for containers
![Test](https://github.com/moby/ipvs/workflows/Test/badge.svg) [![GoDoc](https://godoc.org/github.com/moby/ipvs?status.svg)](https://godoc.org/github.com/moby/ipvs) [![Go Report Card](https://goreportcard.com/badge/github.com/moby/ipvs)](https://goreportcard.com/report/github.com/moby/ipvs)
ipvs provides a native Go implementation for communicating with IPVS kernel module using a netlink socket.
#### Using ipvs
```go
import (
"log"
"github.com/moby/ipvs"
)
func main() {
handle, err := ipvs.New("")
if err != nil {
log.Fatalf("ipvs.New: %s", err)
}
svcs, err := handle.GetServices()
if err != nil {
log.Fatalf("handle.GetServices: %s", err)
}
}
```
