How to use

creat cluster

const {create} = require(abc4);
const order = {provider: "aws", region: "ap-northeast-1"};
const cluster = await create(order);

order is the option argument object. you can set any cluster setting (including provider specific one) with this object. cluster is the object which has all information about the cluster you just creat (see also Cluster section)

destroy cluster

const {destroy} = require(abc4);
await destroy (cluster.id);

cluster.id is returned string from create()
