LINUX-SSH-KNOWN_HOSTS-SSH Error

Log errors,
I've been doing this all night, Docker.
Because the use of the bridge, so the IP is the same, sometimes in the creation of the container name may also be in conflict with the previous, will be error
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

@ warning:remote HOST Identification has changed! @

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

IT is POSSIBLE this SOMEONE is DOING SOMETHING nasty!

Someone could is eavesdropping on your right now (Man-in-the-middle attack)!

It is also possible, a host key has just been changed.

The fingerprint for the ECDSA key sent by the remote host is

5b:82:47:82:ef:cf:76:96:63:a6:7c:ce:86:7f:eb:9b.

Please contact your system administrator.

Add correct host key in/root/.ssh/known_hosts to get rid of the this message.

Offending ECDSA Key In/root/.ssh/known_hosts:2

ECDSA host key for [192.168.0.141]:2222 had changed and you have requested strict checking.

Host Key verification failed.

Probably meant to be a secret key. What authentication error, cause cannot ssh link login,
The problem is that the current public key is automatically cached each time the link succeeds to SSH. The next time the link is automatically verified, if it is correct, the error pops up.
However, in a Docker environment, if you frequently regenerate Docker containers, it can be difficult to manage with SSH at this time.
A manual method is
Vim ~/.ssh/known_hosts go in and erase all records about the linked IP

The second one is to modify the configuration file
Vim ~/.ssh/config
650) this.width=650; "height=" http://b288.photo.store.qq.com/psb?/81c1194a-ff39-4e50-b1b1-40057b06260f/"src=". qiyvnje8tmlidzzgxmczviwc918ciuhuu58xd5yipc!/b/dcabaaaaaaaa&bo=aqflaaaaaaafaaa! "width=" 361 "style=" vertical-align:top; "alt=" dcabaaaaaaaa&bo=aqflaaaaaaafaaa! "/>
Write two lines of information, restart the system, will not automatically record the secret key,
Mainly facilitates the automatic management of Docker later, but the relative reduction of security
