Intro Dockerfile Example

Example

FROM centos:7
LABEL description=”A basic Apache container on CentOS 7”
ADD CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo
RUN yum -y update &&
yum install -y httpd &&
yum clean all
EXPOSE 80 // 可以設定多個port
CMD [“httpd”,”-D”,”FOREGROUND”] // -D背景執行，沒設定會咬住當前控制權

可針對以上範例做docker build image
