## 2つのPodから成るアプリケーションのServiceを作成
|
||||
|
||||
1. クラスタでHello Worldアプリケーションを稼働させます:
|
||||
```shell
|
||||
kubectl run hello-world --replicas=2 --labels="run=load-balancer-example" --image=gcr.io/google-samples/node-hello:1.0 --port=8080
|
||||
```
|
||||
このコマンドは
|
||||
[Deployment](/docs/concepts/workloads/controllers/deployment/)
|
||||
オブジェクトとそれに紐付く
|
||||
[ReplicaSet](/docs/concepts/workloads/controllers/replicaset/)
|
||||
オブジェクトを作成します。ReplicaSetは、Hello Worldアプリケーションが稼働している2つの
|
||||
[Pod](/docs/concepts/workloads/pods/pod/)
|
||||
から構成されます。
|
||||
|
||||
1. Deploymentの情報を表示します:
|
||||
```shell
|
||||
kubectl get deployments hello-world
|
||||
kubectl describe deployments hello-world
|
||||
```
|
||||
|
||||
1. ReplicaSetオブジェクトの情報を表示します:
|
||||
```shell
|
||||
kubectl get replicasets
|
||||
kubectl describe replicasets
|
||||
```
|
||||
|
||||
1. Deploymentを公開するServiceオブジェクトを作成します:
|
||||
```shell
|
||||
kubectl expose deployment hello-world --type=NodePort --name=example-service
|
||||
```
|
||||
|
||||
1. Serviceに関する情報を表示します:
|
||||
```shell
|
||||
kubectl describe services example-service
|
||||
```
|
||||
出力例は以下の通りです:
|
||||
```shell
|
||||
Name: example-service
|
||||
Namespace: default
|
||||
Labels: run=load-balancer-example
|
||||
Annotations: <none>
|
||||
Selector: run=load-balancer-example
|
||||
Type: NodePort
|
||||
IP: 10.32.0.16
|
||||
Port: <unset> 8080/TCP
|
||||
TargetPort: 8080/TCP
|
||||
NodePort: <unset> 31496/TCP
|
||||
Endpoints: 10.200.1.4:8080,10.200.2.5:8080
|
||||
Session Affinity: None
|
||||
Events: <none>
|
||||
```
|
||||
NodePortの値を記録しておきます。上記の例では、31496です。
|
||||
|
||||
1. Hello Worldアプリーションが稼働しているPodを表示します:
|
||||
```shell
|
||||
kubectl get pods --selector="run=load-balancer-example" --output=wide
|
||||
```
|
||||
出力例は以下の通りです:
|
||||
```shell
|
||||
NAME READY STATUS ... IP NODE
|
||||
hello-world-2895499144-bsbk5 1/1 Running ... 10.200.1.4 worker1
|
||||
hello-world-2895499144-m1pwt 1/1 Running ... 10.200.2.5 worker2
|
||||
```
|
||||
1. Hello World podが稼働するNodeのうち、いずれか1つのパブリックIPアドレスを確認します。
|
||||
確認方法は、使用している環境により異なります。
|
||||
例として、Minikubeの場合は`kubectl cluster-info`、Google Compute Engineの場合は`gcloud compute instances list`によって確認できます。
|
||||
|
||||
1. 選択したノード上で、NodePortの値でのTCP通信を許可するファイヤーウォールを作成します。
|
||||
NodePortの値が31568の場合、31568番のポートを利用したTCP通信を許可するファイヤーウォールを作成します。
|
||||
クラウドプロバイダーによって設定方法が異なります。
|
||||
|
||||
1. Hello World applicationにアクセスするために、Nodeのアドレスとポート番号を使用します:
|
||||
```shell
|
||||
curl http://<public-node-ip>:<node-port>
|
||||
```
|
||||
ここで `<public-node-ip>` はNodeのパブリックIPアドレス、
|
||||
`<node-port>` はNodePort Serviceのポート番号の値を表しています。
|
||||
リクエストが成功すると、下記のメッセージが表示されます:
|
||||
```shell
|
||||
Hello Kubernetes!
|
||||
```
|
||||
|
||||
## service configuration fileの利用
|
||||
|
||||
`kubectl expose`コマンドの代わりに、
|
||||
[service configuration file](/docs/concepts/services-networking/service/)
|
||||
を使用してServiceを作成することもできます。

||||

||||

|
||||
|
||||
Serviceを削除するには、以下のコマンドを実行します:
|
||||
|
||||
kubectl delete services example-service
|
||||
|
||||
Hello Worldアプリケーションが稼働しているDeployment、ReplicaSet、Podを削除するには、以下のコマンドを実行します:
|
||||
|
||||
kubectl delete deployment hello-world
