# Fluid Development Environment with Kind on MacOS

# Requirements

kind (version > v0.10.0)
docker
MacOS

csi-driver and node-driver-registrar(sidecar) need to communicate with kubelet,
so run them in kind container

# Set up steps

# 1. download go source code

In order to run csi-driver and node-driver-registrar code in kind container
download it from go1.16.3.linux-amd64.tar.gz (opens new window) decompress it and put it in ~/go/local/ directory

  ~/go
    |__bin
    |__pkg
    |__src
    |   |__ github.com
    |   |__ sigs.k8s.io
    |   |__ k8s.io
    |__local
    |  |__go

# 2. create kind cluster

$ kind create cluster --config=cluster.yaml

# cluster.yaml
kind: Cluster
apiVersion: kind.x-k8s.io/v1alpha4
name: fluid-dev
nodes:
- role: control-plane
  image: kindest/node:v1.16.1
  extraMounts:
  - hostPath: /your/Mac/go/path # GOPATH value on Mac
    containerPath: /home/work/go

# check kind cluster node
$ kubectl get nodes

# 3. create fluid crds and csi driver to kind cluster

# 4. run csi-driver and node-driver-registrar code in kind node container

start node-driver-registrar

I made a small change to node-driver-registrar (opens new window) based on v1.3.0,
It can be downloaded from fluid-dev-v1.3.0 (opens new window)
The only change is to allow passing reg-path in arguments
Does not affect the csi-driver online

docker exec -ti fluid-dev-control-plane /bin/bash
