如何让 DOCKER_HOST 读取 ~/.ssh/config？答案

【问题标题】：How to make DOCKER_HOST read ~/.ssh/config?如何让 DOCKER_HOST 读取 ~/.ssh/config？

【问题描述】：

我有~/.ssh/config，内容如下

Host hostname
    HostName [REDACTED]
    User ubuntu
    IdentityFile ~/.ssh/google_compute_engine

我可以在终端中使用 with no problem

连接这个主机

ssh hostname

不幸的是，paramiko 似乎无法读取 ~/.ssh/config

DOCKER_HOST="ssh://hostname" docker-compose up -d                 

Traceback (most recent call last):
  File "/usr/bin/docker-compose", line 11, in <module>
    load_entry_point('docker-compose==1.25.0', 'console_scripts', 'docker-compose')()
  File "/usr/lib/python3/dist-packages/compose/cli/main.py", line 72, in main
    command()
  File "/usr/lib/python3/dist-packages/compose/cli/main.py", line 125, in perform_command
    project = project_from_options('.', options)
  File "/usr/lib/python3/dist-packages/compose/cli/command.py", line 53, in project_from_options
    return get_project(
  File "/usr/lib/python3/dist-packages/compose/cli/command.py", line 145, in get_project
    client = get_client(
  File "/usr/lib/python3/dist-packages/compose/cli/command.py", line 116, in get_client
    client = docker_client(
  File "/usr/lib/python3/dist-packages/compose/cli/docker_client.py", line 127, in docker_client
    client = APIClient(**kwargs)
  File "/usr/lib/python3/dist-packages/docker/api/client.py", line 165, in __init__
    self._custom_adapter = SSHHTTPAdapter(
  File "/usr/lib/python3/dist-packages/docker/transport/sshconn.py", line 84, in __init__
    self._connect()
  File "/usr/lib/python3/dist-packages/docker/transport/sshconn.py", line 93, in _connect
    self.ssh_client.connect(
  File "/usr/lib/python3/dist-packages/paramiko/client.py", line 340, in connect
    to_try = list(self._families_and_addresses(hostname, port))
  File "/usr/lib/python3/dist-packages/paramiko/client.py", line 203, in _families_and_addresses
    addrinfos = socket.getaddrinfo(
  File "/usr/lib/python3.8/socket.py", line 918, in getaddrinfo
    for res in _socket.getaddrinfo(host, port, family, type, proto, flags):
socket.gaierror: [Errno -2] Name or service not known

有什么方法可以连接吗？

更新

如果我使用

DOCKER_CERT_PATH=~/.ssh/google_compute_engine DOCKER_HOST="ssh://hostname" docker-compose up -d

我收到了错误

  File "/usr/bin/docker-compose", line 11, in <module>
    load_entry_point('docker-compose==1.25.0', 'console_scripts', 'docker-compose')()

    raise errors.TLSParameterError(

【解决方案1】：

知道了！

我必须这样做

ssh-agent zsh (or bash)
ssh-add -k ~/.ssh/google_compute_engine

然后

DOCKER_HOST="ssh://ubuntu@REDACTED" docker-compose up -d
