Juju를 통해 vmware 에 vm을 만들고 그 위에 kubernetes를 올려본다.
kubernetes charm은 https://jujucharms.com/canonical-kubernetes/ 에서 받을 수 있다.
기본적으로 juju deploy canonical-kubernetes 하면 vcenter를 통해 vm을 생성하고 그 위에 설치 하게 되지만,
vcenter내에 여러개의 cluster가 존재 할 경우 한 곳에 deploy하기 위해서는 bundle file을 수정한다.
아래와 같이 bundle.yaml 파일을 만들거나 위 링크에서 bundle.yaml을 다운 받아서 아래와 같이 수정한 뒤, juju deploy bundle.yaml 을 수행하면 된다
