HAProxy Ingress controller

Ingress controller implementation for HAProxy loadbalancer.

HAProxy Ingress is a Kubernetes ingress controller: it configures a HAProxy instance to route incoming requests from an external network to the in-cluster applications. The routing configurations are built reading specs from the Kubernetes cluster. Updates made to the cluster are applied on the fly to the HAProxy instance.

Develop HAProxy Ingress

Building:

mkdir -p $GOPATH/src/github.com/jcmoraisjr
cd $GOPATH/src/github.com/jcmoraisjr
git clone https://github.com/jcmoraisjr/haproxy-ingress.git
cd haproxy-ingress
make

The following make targets are currently supported:

• install: run go install which saves some building time.
• build (default): compiles HAProxy Ingress and generates an ELF (Linux) executable at rootfs/haproxy-ingress-controller despite the source platform.
• test: run unit tests
• image: generates a Docker image tagged localhost/haproxy-ingress:latest
