我对Vagrant和Docker都是陌生的.
我要在这里做的是通过Vagrant中的docker提供一个容器,并使用Shell Provisioner安装一个小型Webapp.
这是我的Vagrantfile
Vagrant.configure(2) do |config|
# config.vm.provision :shell,path: "bootstrap.sh"
config.vm.provision :shell,inline: 'echo Hi there !!!'
config.vm.provider :docker do |d|
d.name="appEnvironment"
d.image = "phusion/baseimage"
d.remains_running = true
d.has_ssh = true
d.cmd = ["/sbin/my_init","--enable-insecure-key"]
end
end
我在这里面临的问题是,在创建容器之后,它会继续运行以下内容,最终只是停止.
当我输入docker ps时,我可以看到一个正在运行的docker容器,但它没有运行配置部分.我假设这是因为ssh没有成功
==> default: Creating the container...
default: Name: appEnvironment
default: Image: phusion/baseimage

有人可以让我知道我可能在哪里吗？我也尝试更改图像,但没有成功.
首先从以下位置下载phusion提供的不安全密钥：
https://github.com/phusion/baseimage-docker/blob/master/image/insecure_key
*请记住,不安全的密钥应仅用于开发目的.
现在,您需要通过在Dockerfile中添加以下内容来启用ssh：
FROM phusion/baseimage
RUN rm -f /etc/service/sshd/down
RUN /etc/my_init.d/00_regen_ssh_host_keys.sh
RUN /usr/sbin/enable_insecure_key
启用ssh并在Vagrantfile中指定密钥文件：
Vagrant.configure("2") do |config|
config.vm.define "app" do |app|
app.vm.provider "docker" do |d|
d.build_dir = "."
d.cmd = ["/sbin/my_init","--enable-insecure-key"]
d.has_ssh = true
end
end
config.ssh.username = "root"
config.ssh.private_key_path = "path/to/your/insecure_key"
end
改善环境
vagrant up
现在您应该可以通过ssh访问您的容器
vagrant ssh app
