如何将Vagrantfile转换为Dockerfile

我正在尝试使用下面的Vagrantfile来创build一个用于学习目的的Dockerfile。 到目前为止，这是我所提出的：

从Udacity：“关系数据库简介”，这是我的Vagrantfile：

# -*- mode: ruby -*- # vi: set ft=ruby : VAGRANTFILE_API_VERSION = "2" Vagrant.configure(VAGRANTFILE_API_VERSION) do |config| config.vm.provision "shell", path: "pg_config.sh" # config.vm.box = "hashicorp/precise32" config.vm.box = "ubuntu/trusty32" config.vm.network "forwarded_port", guest: 8000, host: 8000 config.vm.network "forwarded_port", guest: 8080, host: 8080 config.vm.network "forwarded_port", guest: 5000, host: 5000 end 

pg_config.sh：

 apt-get -qqy update apt-get -qqy install postgresql python-psycopg2 apt-get -qqy install python-flask python-sqlalchemy apt-get -qqy install python-pip pip install bleach pip install oauth2client pip install requests pip install httplib2 pip install redis pip install passlib pip install itsdangerous pip install flask-httpauth su postgres -c 'createuser -dRS vagrant' su vagrant -c 'createdb' su vagrant -c 'createdb forum' su vagrant -c 'psql forum -f /vagrant/forum/forum.sql' vagrantTip="[35m[1mThe shared directory is located at /vagrant\nTo access your shared files: cd /vagrant(B[m" echo -e $vagrantTip > /etc/motd wget http://download.redis.io/redis-stable.tar.gz tar xvzf redis-stable.tar.gz cd redis-stable make make install

这是我转换为Dockerfile的尝试：

 # Set the base image to Ubuntu FROM ubuntu:14.04 # Update the repository sources list RUN apt-get update # Add the packages RUN \ apt-get -qqy install postgresql python-psycopg2 && \ apt-get -qqy install python-flask python-sqlalchemy && \ apt-get -qqy install python-pip && \ pip install bleach && \ pip install oauth2client && \ pip install requests && \ pip install httplib2 && \ pip install redis && \ pip install passlib && \ pip install itsdangerous && \ pip install flask-httpauth && \ su postgres -c 'createuser -dRS vagrant' && \ su vagrant -c 'createdb' && \ su vagrant -c 'createdb forum' && \ su vagrant -c 'psql forum -f /vagrant/forum/forum.sql' && \ vagrantTip="[35m[1mThe shared directory is located at /vagrant\nTo access your shared files: cd /vagrant(B[m" && \ echo -e $vagrantTip > /etc/motd && \ wget http://download.redis.io/redis-stable.tar.gz && \ tar xvzf redis-stable.tar.gz && \ cd redis-stable && \ make && \ make install # Expose the default port EXPOSE 5000 

运行后

 docker build -t fullstack-vm . 

我收到以下错误：

 debconf: unable to initialize frontend: Dialog debconf: (TERM is not set, so the dialog frontend is not usable.) debconf: falling back to frontend: Readline debconf: unable to initialize frontend: Readline debconf: (This frontend requires a controlling tty.) debconf: falling back to frontend: Teletype dpkg-preconfigure: unable to re-open stdin: 

在Dockerfile中需要纠正哪些内容才能正常运行？

你可以加

 ENV DEBIAN_FRONTEND noninteractive 

到你的Dockerfile 。
