Vagrant无法通过ssh连接到docker

我正试图通过vagrant连接到docker实例

这是我的Dockerfile：

FROM centos:7
#RUN yum -y update
RUN yum -y install openssh-server wget sudo
EXPOSE 22
RUN mkdir -p /home/vagrant/.ssh
RUN chmod 0700 /home/vagrant/.ssh
RUN useradd --create-home -s /bin/bash vagrant
WORKDIR /home/vagrant
RUN mkdir -p /home/vagrant/.ssh
RUN echo "ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEA6NF8iallvQVp22WDkTkyrtvp9eWW6A8YVr+kz4TjGYe7gHzIw+niNltGEFHzD8+v1I2YJ6oXevct1YeS0o9HZyN1Q9qgCgzUFtdOKLv6IedplqoPkcmF0aYet2PkEDo3MlTBckFXPITAMzF8dJSIFo9D8HfdOV0IAdx4O7PtixWKn5y2hMNG0zQPyUecp4pzC6kivAIhyfHilFR61RGL+GPXQ2MWZWFYbAGjyiYJnAmCP3NOTd0jMZEnDkbUvxhMmBYSdETk1rRgm+R4LOzFUGaHqHDLKLX+FIPKcF96hrucXzcWyLbIbEgE98OHlnVYCzRdK8jlqm8tehUc9c9WhQ== vagrant insecure public key" > /home/vagrant/.ssh/authorized_keys
RUN chmod 0600 /home/vagrant/.ssh/authorized_keys
RUN chown -R vagrant: /home/vagrant/.ssh
RUN mkdir -p /etc/sudoers.d
RUN install -b -m 0440 /dev/null /etc/sudoers.d/vagrant
RUN echo 'vagrant ALL=NOPASSWD: ALL' >> /etc/sudoers.d/vagrant
RUN sed -i 's|#AuthorizedKeysFile|AuthorizedKeysFile|g' /etc/ssh/sshd_config
CMD ["/usr/sbin/sshd", "-D"]

这是我的流浪汉档案：

# -*- mode: ruby -*-
# vi: set ft=ruby :

Vagrant.configure(2) do |config|
 config.vm.provider "docker" do |d|
    d.build_dir = "."
    d.name = "test"
    d.has_ssh = true
  end
  config.ssh.port = 22
end

在流浪之后，我得到了这个：

==> default: Waiting for machine to boot. This may take a few minutes...
    default: SSH address: 172.17.0.2:22
    default: SSH username: vagrant
    default: SSH auth method: private key
    default: Warning: Connection refused. Retrying...
    default: Warning: Connection refused. Retrying...
    default: Warning: Connection refused. Retrying...

它多次打印最后一行，我用Ctrl-C停止

如果我只是运行docker build-t stacko.&docker run stacko流程将卡在此处：

Could not load host key: /etc/ssh/ssh_host_rsa_key
Could not load host key: /etc/ssh/ssh_host_ecdsa_key
Could not load host key: /etc/ssh/ssh_host_ed25519_key

有什么不对劲吗

我的解决方案

似乎问题出在docker主机密钥上。所以我再生了它们

FROM centos:7

ENV container docker

如果solmeone能解释为什么会这样（ssh密钥有什么问题）

您的ssh根本没有运行，那就太好了。你需要更好地理解docker CMD:@michael_bitard。你的意思是只执行最后一个命令？但我怎么才能让容器保持运行状态呢？你不能，当你

docker build

时，docker文件的两行之间的每个进程都会停止，你必须在使用

docker run

@michael_bitard时启动ssh服务器。你的意思是：sudo vagrant docker run——服务ssh重启？但这是行不通的。给出错误：Stderr:/usr/bin/docker:守护进程的错误响应：未找到或不存在容器命令“service”。@michael\u bitard。我编辑了我的Dockerfiel。我想现在ssh应该运行了？但现在我得到了默认值：警告：远程连接断开。重试。。。
