Docker内でsupervisordを使うための検証メモ

### ロギング

```

stdout_logfile=/dev/stdout

stdout_logfile_maxbytes=0

stderr_logfile=/dev/stderr

stderr_logfile_maxbytes=0

```

を書いて親プロセスに標準出力と標準エラー出力をリダイレクトすれば良い

### 終了処理

```

docker kill --signal="TERM" コンテナ名

```

supervisord に `TERM` を送ると、子プロセスも即座に`TERM` を受取り、終了することを確認。

```
