# FlexLB kubernetes controller

FlexLB kubernetes controller to add load balancer endpoint for service

## Build

### Clone code

```sh
git clone https://gitee.com/flexlb/flexlb-kube-controller.git
```

### Build binary

#### For Linux
```sh
# build binary (for test purpose)
make

# build docker (for production purpose)
docker build -t flexlb-kube-controller:0.4.1 .

# push docker
docker push flexlb-kube-controller:0.4.1
```

### Run

#### Install CRDs

```sh
# copy target kubernetes config to ~/.kube/config

# install CRDs
kubectl apply -f config/crd/bases
```

#### Run on the fly

```sh
# set parameters
NODEIP=<kube-controller-ip>
export METRICS_BIND_ADDRESS=${NODEIP}:8000
export HEALTH_PROBE_BIND_ADDRESS=${NODEIP}:8001
export FLEXLB_TLS_CA_CERT=../certs/ca.crt
export FLEXLB_TLS_CLIENT_CERT=../certs/client.crt
export FLEXLB_TLS_CLIENT_KEY=../certs/client.key
export FLEXLB_REFRESH_INTERVAL=30
export FLEXLB_NAMESPACE=kube-system
export FLEXLB_TRAFFIC_NETWORK=192.168.1.0/24

# run on the fly
make run
```

#### Deploy

```sh
# install rbac
kubectl apply -f config/rbac

# edit config/controller/flexlb-client-certs.yaml, change to target flexlb-api client certificate
base64 -w 0 ../certs/ca.crt
base64 -w 0 ../certs/client.crt
base64 -w 0 ../certs/client.key

# install controller
kubectl apply -f config/controller
```

#### Test

```sh
# edit config/samples/crd_v1_flexlbcluster.yaml, change flex-api endpoint
# create cluster config
kubect apply -f config/samples/crd_v1_flexlbcluster.yaml

# create instance manually
kubectl apply -f config/samples/crd_v1_flexlbinstance.yaml

# create a load-balancer service and test it

```
