Intro
kind is a tool for running local Kubernetes clusters using Docker container “nodes”.
kind was primarily designed for testing Kubernetes itself, but may be used for local development or CI.
Setup Golang development
- Install Go tools. Follow docs.
- Config
$GOROOT and $GOPATH
$GOROOT is for compiler/tools that comes from go installation. This should be configured to the go directory that was installed.$GOPATH is for your own go projects / 3rd party libraries (downloaded with “go get”). This can be a new, empty directory to start with.
e.g. I have the following:
1
2
| $ echo $GOROOT $GOPATH
/Users/agao/go /Users/agao/goprojects
|
Install Kind
Follow docs
Since I have Golang development env, I can just do
1
| go get sigs.k8s.io/kind
|
This will put kind in $(go env GOPATH)/bin
