問題描述 在Docker中建立centos 7 container，sshd進程啟動後，通過docker 宿主機ssh串連該container，提示資訊：

[root@centos-cloudera-1 ~]# ssh 10.10.200.4The authenticity of host '10.10.200.4 (10.10.200.4)' can't be established.ECDSA key fingerprint is SHA256:Xn2tjX3zW88QjDbirg7a1K39jYYvCz2Vd13iiehP2p0.ECDSA key fingerprint is MD5:1d:76:e4:ec:59:70:8c:7d:da:4b:e9:d7:f2:d0:4b:47.Are you sure you want to continue connecting (yes/no)? yesWarning: Permanently added '10.10.200.4' (ECDSA) to the list of known hosts.Permission denied (publickey,gssapi-keyex,gssapi-with-mic).

解決方案 1.通過yum刪除現有的openssh-server，然後重新安裝openssh-server

#yum -y remove openssh-server#yum -y install openssh-server

2.設定密鑰 #

#sshd-keygen

3.修改sshd_config設定檔中的PubkeyAuthentication選項，設定該選項值為yes

PubkeyAuthentication yes

4.啟動sshd

#/usr/sbin/sshd

5.通過其他伺服器串連該container
