docker - Docker作为Vagrant的提供商

Question

我正在使用Saltstack / Shell来提供一个无所事事的机器，但是现在我想将Docker添加为提供者。我遇到了超时问题，因此我修改了超时值。现在看来这台机器永远都无法运转:我一直在等待，什么都没发生!

这是我的Vagrant文​​件:

Vagrant.configure(2) do |config|

  config.vm.define :nodejs do |nodejs|
    #nodejs.vm.box = "ubuntu/trusty64"
    nodejs.vm.hostname = "nodejs"
    nodejs.ssh.pty = true

    nodejs.vm.boot_timeout = 50000

    nodejs.vm.network "forwarded_port", guest: 80, host: 8001
    nodejs.vm.network  "forwarded_port", guest: 3600, host: 8002
    nodejs.vm.network "private_network", ip: "10.0.0.10"

    nodejs.vm.synced_folder "salt/roots/", "/srv/salt/"
    nodejs.vm.synced_folder "salt/minion.d/", "/etc/salt/minion.d/"
    nodejs.vm.synced_folder "salt/formulas/", "/srv/formulas/"

    nodejs.vm.provider :virtualbox do |vb|
      vb.gui = true
    end


    nodejs.vm.provision :salt do |salt|
      salt.verbose = true
      salt.minion_config = "salt/minion.yml"
      salt.run_highstate = true
      salt.colorize = true
      salt.log_level = 'all'
      salt.always_install = true
      salt.colorize = true
      salt.bootstrap_options = '-F -c /tmp/ -P'
    end

    nodejs.vm.provider "virtualbox" do |v|
      v.customize ["modifyvm", :id, "--memory", "2048"]
      v.customize ["modifyvm", :id, "--cpus", "2"]
    end

    nodejs.vm.provision "shell", path: "bootstrap/nodejs_bootstrap.sh"


    nodejs.ssh.username = 'docker'
    nodejs.ssh.password = 'tcuser'


    nodejs.vm.provider :docker do |docker|
      docker.force_host_vm = true
      docker.has_ssh = true 
      docker.image = 'ubuntu'
      docker.remains_running = false
    end






  end
end 

如果没有Docker，一切都会正常进行，直到我添加了这一部分:

    nodejs.ssh.username = 'docker'
    nodejs.ssh.password = 'tcuser'


    nodejs.vm.provider :docker do |docker|
      docker.force_host_vm = true
      docker.has_ssh = true 
      docker.image = 'ubuntu'
      docker.remains_running = false
    end

身份验证无效，我必须在每个文件同步时手动键入密码! (这不是真正的问题)

这就是问题:

看来我会等待永恒!

有什么建议么 ？

Answer 1

因此，您正在执行以下操作:

docker.has_ssh = true 

但是您的Docker镜像没有sshd:

docker.image = 'ubuntu'

您可以通过以下方式进行验证:

~$ docker run -ti ubuntu /bin/bash
user@4baf7c72d5a8:/# sshd
bash: sshd: command not found
user@4baf7c72d5a8:/#

您必须创建一个具有sshd的应用程序，或使用通过安装了sshd的Dockerfile创建的应用程序。

同样，一旦您看到上面的问题。跑:

docker ps

确保您的容器正在运行。如果不是，请检查您的 /var/log/docker.log文件
