docker-machine create不断询问密码。

Question

我正在尝试docker-machine create到Ubuntu16.04这样的主机上：

    ssh-keygen -R ${remote_host}
    ssh-copy-id -i ~/.ssh/id_host_rsa.pub root@${remote_host}

    docker-machine create \
        --driver generic \
        --generic-ip-address=${remote_host} \
        --generic-ssh-key ~/.ssh/id_host_rsa \
        --generic-ssh-user=root ${machine_name}

版本信息：

docker --version
Docker version 19.03.6, build 369ce74a3c

docker-machine --version
docker-machine version 0.16.2, build bd45ab13

我一再被要求要一个密码。为什么会这样呢？

这是输出：

...

Are you sure you want to continue connecting (yes/no)? yes

Answer 1

造成这个问题的原因是~/.ssh/config的排序。

我首先在config中有一个config条目，在相应的特定服务器Host XX.XX.XX.XX条目之前。

我在~/.ssh/config的末尾移动了通配符条目，现在密码不再被不断地询问，问题现在已经解决了。

我是怎么帮到别人的。
