追加する方法kubernetesは、ライブネスプローブ

Question

私は

1. Centos.6
   上のTCPポートを使用して生存性プローブを適用するために、単純なYAMLファイルを書いていますが、私はCentOSの引か：公開リポジトリから6の画像を
2. は、コンテナを開始しました画像を使用します。
3. インストールmysqlの、そして開かれたポート（3306）を確認するためにそれを開始し
4. としてローカルリポジトリにコミットし、 "MySQLのテスト：v0.1の"

と

apiVersion: v1 
kind: Pod 
metadata: 
    labels: 
    test: mysql-test 
    name: mysql-test-exec 
spec: 
    containers: 
    - name: mysql-test 
    args: 
    - /sbin/service 
    - mysqld 
    - start 
    image: mysql-test:v0.1 
    livenessProbe: 
     tcpSocket: 
     port: 3306 
     initialDelaySeconds: 15 
     periodSeconds: 20 

以下のようにポッドを適用

ただし、ポッドのステータスはCrashLoopBackOff、work02のコンテナのステータスはです。終了です。

Answer 1

Iはドッカー画像で動作するように引数を除去しなければなりません。以下のデプロイメントが私のために機能します代わりに `ドッキングウィンドウのlogs`の

apiVersion: v1 
kind: Pod 
metadata: 
    labels: 
    test: mysql-test 
    name: mysql-test-exec 
spec: 
    containers: 
    - name: mysql-test 
    image: mysql:5.6 
    env: 
     - name: MYSQL_ROOT_PASSWORD 
     value: mysql456 
    livenessProbe: 
     tcpSocket: 
     port: 3306 
     initialDelaySeconds: 15
