Я вижу эту ошибку в некоторых заданиях Jenkins
Cannot contact jenkins-slave-l65p0-0f7m0: hudson.remoting.ChannelClosedException: Channel "unknown": Remote call on JNLP4-connect connection from 100.99.111.187/100.99.111.187:46776 failed. The channel is closing down or has closed down
У меня есть настройка главного и подчиненного jenkins.
На подчиненном устройстве обнаружены следующие журналы
java.nio.channels.ClosedChannelException

Я сомневаюсь, что это имеет какое-то отношение к kubernetes, но все же выдает его там.
