Jenkins新建任务时，输入远程仓库地址设置，选择凭证后一直提示连不上 jenkins stderr: No ECDSA host key is known for gitee.com and you have requested strict checking. Host key verification failed.

我的jenkins是docker部署的

需要在jenkins的容器里 执行以下命令访问git上的仓库地址，把git的主机添加到/root/.ssh/known_hosts(执行命令前known_hosts这个文件是不存在的，执行后就有了)

root@80b05f3c5097:~/.ssh# git ls-remote -h git@gitee.com:XXXXX/autotest.git HEAD
The authenticity of host ‘gitee.com (212.64.63.215)’ can’t be established.
ECDSA key fingerprint is SHA256:FQGC9Kn/eye1W8icdBgrQp+KkGYoFgbVr17bmjey0Wc.
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
Warning: Permanently added ‘gitee.com,212.64.63.215’ (ECDSA) to the list of known hosts.

-rw——- 1 root root 2602 Oct 25 02:42 id_rsa
-rw-r–r– 1 root root 571 Oct 25 02:42 id_rsa.pub
-rw-r–r– 1 root root 444 Oct 25 03:55 known_hosts

然后jenkins就不报错了
