docker启动时服务自启动

例sshd服务

1.dockerd脚本

!/bin/bash

echo “Service sshd starting…”
/usr/sbin/sshd
echo “Service sshd started!”

2.Dockerfile

FROM centosbase //基础镜像

MAINTAINER zwh 459976146@qq.com

ADD dockerd /etc/rc.d/init.d/
RUN chmod 777 /etc/rc.d/init.d/dockerd

ENV JAVA_HOME=/usr/local/jdk1.8.0_111 //宿主机jdk
ENV PATH=JAVAHOME/bin:<script type="math/tex" id="MathJax-Element-19">JAVA_HOME/bin:</script>PATH
ENV CLASSPATH =.:JAVAHOME/lib/dt.jar:<script type="math/tex" id="MathJax-Element-20">JAVA_HOME/lib/dt.jar:</script>JAVA_HOME/lib/tools.jar

CMD /etc/rc.d/init.d/dockerd

3.创建镜像
docker build -t sshd:file .

4.创建容器

docker run -d -t –name sshdfile -p 2200:22 sshd:file
