Google開源的容器集群管理系統：Kubernetes

Kubernetes 是來自 Google 云平臺的開源容器集群管理系統。基于 Docker 構建一個容器的調度服務。該系統可以自動在一個容器集群中選擇一個工作容器供使用。其核心概念是 Container Pod。詳細的設計思路請參考這里。

Running a container (simple version)

Once you have your instances up and running, the build-go.sh script sets up your Go workspace and builds the Go components.

The cloudcfg.sh script spins up two containers, running Nginx and with port 80 mapped to 8080:

cd kubernetes
hack/build-go.sh
cluster/cloudcfg.sh -p 8080:80 run dockerfile/nginx 2 myNginx

To stop the containers:

cluster/cloudcfg.sh stop myNginx

To delete the containers:

cluster/cloudcfg.sh rm myNginx

Running a container (more complete version)

Assuming you've run hack/dev-build-and-up.sh and hack/build-go.sh:

cd kubernetes
cluster/cloudcfg.sh -c api/examples/pod.json create /pods

Where pod.json contains something like:

{
  "ID": "nginx",
  "desiredState": {
    "image": "dockerfile/nginx",
    "networkPorts": [{
      "containerPort": 80,
      "hostPort": 8080
    }]
  },
  "labels": {
    "name": "foo"
  }
}

Look in api/examples/ for more examples

Tearing down the cluster

cd kubernetes
cluster/kube-down.sh
