基于centos 创建stress镜像——源码安装stress

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

 

1. 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"]

    

2. 根据Dockerfile生成创建一个stress镜像

   docker build -t centos-stress-source:1.0.2 .

3. 查看镜像 

   [vagrant@localhost stress]$ docker images
   REPOSITORY                                       TAG                 IMAGE ID            CREATED             SIZE
   centos-stress-source                             1.0.2               4f8b1ae5f7e8        7 minutes ago       546MB

    

4. 测试是否可用

   [vagrant@localhost stress]$ docker run -ti --rm -m 200M --memory-swap=300M centos-stress-source:1.0.2 --vm 1 --vm-bytes 280M 
   stress: info: [1] dispatching hogs: 0 cpu, 0 io, 1 vm, 0 hdd
