Docker如何同时启动多个服务

前几篇Docker的文章介绍启动容器时都是只启动一个后台服务，今天来说说怎样通过supervisor来启动多个服务

1. 首先创建一个目录并在目录下创建一个Dockerfile，文件内容如下

FROM centos:centos6MAINTAINER Fanbin Kong "kongxx@hotmail.com"RUN rpm -ivh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpmRUN yum install -y openssh-server sudo mysql-server mysql supervisorRUN sed -i 's/UsePAM yes/UsePAM no/g' /etc/ssh/sshd_config  RUN useradd adminRUN echo "admin:admin" | chpasswdRUN echo "admin ALL=(ALL)  ALL" >> /etc/sudoers RUN ssh-keygen -t dsa -f /etc/ssh/ssh_host_dsa_keyRUN ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_keyRUN mkdir /var/run/sshdRUN /etc/init.d/mysqld start &&/ mysql -e "grant all privileges on *.* to 'root'@'%' identified by 'letmein';"&&/ mysql -e "grant all privileges on *.* to 'root'@'localhost' identified by 'letmein';"&&/ mysql -u root -pletmein -e "show databases;"RUN mkdir -p /var/log/supervisorCOPY supervisord.conf /etc/supervisord.confEXPOSE 22 3306CMD ["/usr/bin/supervisord"]
