.NET Core 1.0学习(3)-作了个靠谱点的docker image)

碰到的错误就是那permission denied '/root/.config/configstore/insight-yo.yml'呀，Native thread-sleep not available呀NuGet cache之类的错误。前者是yeomon的，后者是nodejs安装的不够新（apt-get install nodejs的是0.10级别的版本，谁想的到啊）

作好的docker image叫osexp2000/dnetcore-docker-image 。

docker run -it osexp2000/dnetcore-docker-image

进去以后就是bash，以devuser用户运行在/home/devuser，这个用户可以sudo（无需密码）。

进去就能够顺利的运行aspnet模版生成工具yeomen了。

yo aspnet

里面什么npm和yeomen之类的东西都准备好了，甚至基本的vim,lsof，netstat之类的都准备好了，否则真不方便查看环境。

运行的样子是这样的：

$ docker run -it osexp2000/dnetcore-docker-image
devuser@640be8c28a81:~$ id
uid=1000(devuser) gid=1000(devuser) groups=1000(devuser),27(sudo)
devuser@640be8c28a81:~$ yo aspnet
? ==========================================================================
We're constantly looking for ways to make yo better! 
May we anonymously report usage statistics to improve the tool over time? 
More info: https://github.com/yeoman/insight & http://yeoman.io
========================================================================== Yes

Dockerfile放在这儿了。不多，干脆贴下来。

FROM microsoft/dotnet

RUN apt-get update
RUN apt-get install -y apt-utils

#add developer user and switch to it
RUN apt-get install -y sudo
RUN adduser --disabled-password --gecos "Developer" devuser
RUN adduser devuser sudo
RUN echo "devuser ALL=(ALL:ALL) NOPASSWD: ALL" | (EDITOR="tee -a" visudo)
RUN chown -R root:sudo /usr/local #this is also important so some tools like yoemen will not complains
USER devuser
WORKDIR /home/devuser

#these are basic utilities
RUN sudo apt-get install -y bash-completion vim less man
RUN sudo apt-get install -y lsof tree psmisc
RUN sudo apt-get install -y net-tools iputils-ping netcat curl wget



#install nodejs 6.x
RUN curl -sL https://deb.nodesource.com/setup_6.x | sudo bash -
RUN sudo apt-get install -y nodejs


#install aspnet generator
RUN sudo npm install -g yo bower grunt-cli gulp
RUN sudo npm install -g generator-aspnet

RUN sudo rm -f /core
RUN sudo rm -fr /tmp/NuGetScratch

能够本身存起来build成docker image

docker build -t IMAGE_NAME_HERE --rm - < Dockerfile

下次再沿着Your First ASP.NET Core Application on a Mac Using Visual Studio Code — ASP.NET documentation继续学。不过我想看看如何经过Mac OS X里的Visual Studio Code来直接把代码发布到docker里。
