修改代码后提交，并推送到自己的仓库。 $ #do some change on the content $ git commit -am "Fix issue #1: change helo to hello" $ git push 在 GitHub 网站上提交 pull request。 定期使用项目仓库内容更新自己仓库内容。 $ git remote add upstream https://github 所需要的命令主要为 docker run 。 例如，下面的命令输出一个 “Hello World”，之后终止容器。 $ sudo docker run ubuntu:14.04 /bin/echo 'Hello world' Hello world 这跟在本地直接执行 /bin/echo 'hello world' 几乎感觉不出任何区别。 下面的命令则启动一个 bash 终端，允许用户进行交互。 -d 参 数来实现。 例如下面的命令会在后台运行容器。 $ sudo docker run -d ubuntu:14.04 /bin/sh -c "while true; do echo hello world; sleep 1; done" 1e5535038e285177d5214659a068137486f96ee5c2e85a4ac52dc83f2ebe4147 容器启动后会返回一个唯一的
