I have a Yubikey 4 configured with a SSH key bundled inside and it works perfectly if I'm just doing simple ssh into servers with this key configured.
But when I try to run ansible with this configuration, it gives me this error:
fatal: [web01]: UNREACHABLE! => {

I'm assuming it requires a $HOME/.ssh/id_rsa file present in the filesystem, is there a way to workaround this?
答案 0 :(得分：0)
问题出在Ansible的配置上：
ssh_args = -o IdentitiesOnly=yes
我删除了
-o IdentitiesOnly=yes选项。奏效了。
