Docker conatiner中的Ansible无法通过ssh连接到Hetzner主机

Question

我是Ansible的新手，我正尝试在Docker (Windows10)上运行一本剧本，但它无法ssh到Hetzner云中。

我已经创建了一个在Docker中运行Ansible的Makefile。

# Makefile
run_playbook:
    @docker run --rm \
        -v "C:/Users/myuser/.ssh/hetzner/id_rsa:/root/.ssh/id_rsa" \
        -v "C:/Users/myuser/.ssh/hetzner/id_rsa.pub:/root/.ssh/id_rsa.pub" \
        -v $(CURDIR)/ansible.cfg:/etc/ansible/ansible.cfg \
        -v $(CURDIR):/myapp-ansible \
        -w /myapp-ansible \
        williamyeh/ansible:alpine3 \
        ansible-playbook -i staging site.yml -vvv

这是staging清单

[myapp]
<HETNER_SERVER_NAME> ansible_host=<HETZNER_SERVER_IP> ansible_user=root

这是ansible.cfg

# ansible.cfg
[defaults]
host_key_checking = false
roles_path = /myapp-ansible/roles

[privilege_escalation]
become = True
become_method = sudo
become_user = root

问题是，当我运行make run_playbook命令时，我得到错误Failed to connect to the host via ssh。

所以我尝试从docker容器手动连接，看看会发生什么，结果如下

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@         WARNING: UNPROTECTED PRIVATE KEY FILE!          @

我尝试使用sudo chmod 600 /root/.ssh/id_rsa更改id_rsa权限，但似乎没有效果

$ ls -l /root/.ssh
-rwxr-xr-x    1 root     root          2610 Aug 25 13:38 id_rsa
-rwxr-xr-x    1 root     root           577 Aug 25 13:38 id_rsa.pub
-rw-r--r--    1 root     root           176 Aug 26 08:42 known_hosts

因此，我尝试按照here的建议在Windows中直接更改id_rsa权限，但得到的结果与之前相同。

需要注意的是，在Windows中，我可以使用相同的私钥通过Putty进行ssh，没有任何问题。

提前感谢

在谷歌了很多次之后，我找到了this article，所以我更改了run_playbook，如下所示：

run_playbook:
    @docker run -t --rm \
        -v "C:/Users/myuser/.ssh/hetzner/id_rsa:/tmp/.ssh/id_rsa" \
        -v "C:/Users/myuser/.ssh/hetzner/id_rsa.pub:/tmp/.ssh/id_rsa.pub" \
        -v $(CURDIR):/myapp-ansible \
        -w /myapp-ansible \
        williamyeh/ansible:alpine3 \
        /bin/sh -c "cp -R /tmp/.ssh /root/.ssh && chmod 700 /root/.ssh && chmod 644 /root/.ssh/id_rsa.pub && chmod 600 /root/.ssh/id_rsa"
        ansible-playbook -i staging site.yml
