命令docker运行创build空的容器
命令docker run创build空的容器。 我的意思是docker的形象build立成功，但是当我运行容器没有我的更改。 我正在与stream浪者的Ubuntu 16.04工作。 我的docker文件：
FROM node:6.2.0-wheezy MAINTAINER Lukasz Migut RUN mkdir -p /app ADD package.json /app/package.json RUN cd /app/ && \ npm cache clear && \ npm install --no-bin-links --quiet RUN mkdir -p /var/www/backend WORKDIR /var/www/backend COPY entrypoint.sh /entrypoint.sh CMD ["/bin/bash", "/entrypoint.sh"] EXPOSE 8080
这是在docker build .之后输出的docker build .

接下来，我尝试运行容器与docker run -it node:6.2.0-wheezy /bin/bash ，当我在容器上login时，我看不到例如创build文件夹formsDockerfile和没有node_modules。
我做错了什么，为什么我看不到变化？
您构build了一个图像…它是您的docker images命令中标记为“<none>”的图像。 但是，当您尝试运行容器时，您使用了基于新图像的旧图像。 你的改变是新的形象，而不是旧的。
为了得到它的工作，你必须标记你的新形象的名称，并使用该名称…
docker build -t MYIMAGENAME . docker run -it MYIMAGENAME /bin/bash
