az acs kubernetes get-credentials | ECキーが無効です。 | ssh known_hostsが壊れた

Question

私はこの問題にぶつかりました。このバグを見つけるにはしばらく時間がかかりました。何か直感的で推測された推測とstrace -f commandです。 私はそれが間違ってparamicoの例外をキャッチされていると思いますか？ライブラリ、いくつかのAzure CLI例外キャッチャーによって隠されています。

とにかく、私はそれを残すので、未来の未来、あなたはそれを見つけることができます。

az acs kubernetes get-credentials 
Invalid EC key. 


$ strace -f az acs kubernetes get-credentials

Answer 1

側のトピック失敗しなかったことを奇妙な： 行を分割した後、エラーメッセージがより読みやすい出力に変更されました。最後に、私はそれを機能させるために破損した行を削除しました。
