docker0ブリッジのステータスが有効/無効を切り替えますが、何が原因ですか？
Docker0ブリッジデバイスで異常な動作をするCoreOSベアメタルインスタンスがいくつかあります。
これが発生しているインスタンスの1つで、私はcouchbaseサーバーを実行していて、それがリバランスでいくつかの問題を引き起こしました。この問題が発生していないノードにcouchbaseを移動すると、その問題は解消しました。
何が原因ですか？ブリッジデバイスの状態を決定するものは何ですか？
ハードウェアは同じです。 IPアドレスを除いて、構成は同じです。

これは、Dockerブリッジの一般的な動作です。コンテナーが起動または停止するたびに、ブリッジの状態が変化します。
カウチベースに影響はありますか？
