上一篇文章进行了yum安装stress，这次对stress进行源码编译安装，并且生成新的镜像
- 创建Dockerfile目录
[vagrant@localhost ~]$ mkdir -p /tmp/stress
[vagrant@localhost stress]$ sudo vi Dockerfile
FROM library/centos ADD Centos-7.repo /etc/yum.repos.d/CentOS-Base.repo
ADD stress-1.0.4.tar.gz /usr/local/src
RUN yum clean all && yum makecache && yum install -y make automake autoconf gcc gcc-c++
WORKDIR /usr/local/src/stress-1.0.4
RUN ./configure --prefix=/usr/local/stress
RUN make && make install
ENV PATH /usr/local/stress/bin:$PATH
#CMD与ENTRYPOINT的区别在于执行docker run时参数传递的方式不同
ENTRYPOINT ["stress", "--verbose"] - 根据Dockerfile生成创建一个stress镜像
docker build -t centos-stress-source:1.0.2 .
- 查看镜像
[vagrant@localhost stress]$ docker images
