私はホストデータボリュームを持つmysql-5.5を実行しているドッカーコンテナを持っています。コンテナをmysql-5.6にアップグレードしています。私は同じホストボリュームを持つ新しいコンテナを開始しています。 mysql.userテーブルのクラッシュのために、MySQLがコンテナ内でクラッシュしていました。dockerコンテナのmysqlデータディレクトリを移行するにはどうすればいいですか？

コマンド： 'kill -9 31281'を使用した後は、それはまだドッカーのコンテナに残っているのですか、コンテナからログアウトしますか？ –
mysqlが私の 'CMD'ではないので、私のコンテナは生きています。私は監視員を使ってtomcatのような他のプロセスを実行しています。だから、私のCMDは、mysqlを設定して起動するスクリプトであり、その後スーパーバイザが処理します。私はそれがドッカーコンテナの問題ではないと考えています。参考文献で述べたように、それはドッカーなしで再現可能である。 – Gangaraju
