Docker构建开发环境

        以往在新的机器上构建开发环境时，往往需要安装比较多的工具软件，这个过程比较耗时。有人会说，那可以把这些命令固化在shell脚本中。当然这也是一个可行的方法。

        随着Docker的发展，容器与容器云大行其道。本着熟悉Docker的想法，加之Docker具有简化配置、快速部署的特点，这里尝试使用Docker来构建开发环境。

        原始镜像为Ubuntu，常用的开发工具如GCC、G++、GIT等，并安装SSH，支持用户密码登陆以进行开发。由于Ubuntu默认的源的速度较慢，可以考虑更换为国内的，这里选择的是http://mirrors.tuna.tsinghua.edu.cn/ubuntu/。下面是详细的步骤记录。

        sources.list：

# deb cdrom:[Ubuntu 16.04 LTS _Xenial Xerus_ - Release amd64 (20160420.1)]/ xenial main restricted
deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial main restricted
deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-updates main restricted
deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial universe
deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-updates universe
deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial multiverse
deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-updates multiverse
deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-backports main restricted universe multiverse
deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-security main restricted
deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-security universe
deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-security multiverse

        Dockerfile：

RUN echo "takchi:123456" | chpasswd

# Container should expose ports.  
EXPOSE 36000
CMD ["/usr/sbin/sshd", "-D"]

        构建镜像：

docker build -t ubuntu:devel ./

        启动容器：

docker run -it -p 36000:36000 --privileged=true -v /opt/projects:/home/takchi/ ubuntu:devel

        ssh登录：

ssh -p 36000 takchi@${HOST_IP}
