一个容器运行多个服务案例(nginx+sshd) docker

docker手动制作容器镜像: https://www.baimeidashu.com/10674.html

1.基于上一篇 启动的nginx镜像为基础镜像

docker exec -it silly_visvesvaraya bash

[root@1b4669019a3d /]# yum provides sshd  # 判断sshd属于哪个软件包

[root@1b4669019a3d /]# yum -y install openssh-server initscripts # 安装opssh-server软件包

 cat /start.sh 
#!/bin/bash

# Inint root password.
if [ -n "$ADMIN_PASSWD" ];then
   echo $ADMIN_PASSWD | passwd root --stdin
elif [ -n "$1" ]; then
   echo $1 | passwd root --stdin
else 
  echo 123 | passwd root --stdin
fi


# start nginx server
# nginx -g "daemon off;"
nginx

# get key
/usr/sbin/sshd-keygen


# start sshd service
/usr/sbin/sshd -D

2.提交镜像并启动yum容器

docker commit  silly_visvesvaraya  baimei-centos-nginx:v0.3 

[root@centos201 ~]# docker commit  silly_visvesvaraya  baimei-centos-nginx:v0.3 
[root@centos201 ~]# docker run -dp 1180:80 -p 1122:22 baimei-centos-nginx:v0.3 
[root@centos201 ~]# docker run -dp 1180:80 -p 1122:22 baimei-centos-nginx:v0.3 bash -x /start.sh 666
[root@centos201 ~]# docker run -dp 2280:80 -p 2222:22 -e ADMIN_PASSWD=888 baimei-centos-nginx:v0.3 
[root@centos201 ~]# docker run -dp 3380:80 -p 3322:22 -e ADMIN_PASSWD=888 baimei-centos-nginx:v0.3 bash -x /start.sh 666
