Docker（十二）：Docker集群管理之Compose

1、Compose安装

　　curl -L https://github.com/docker/compose/releases/download/1.1.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose

　　chmod +x /usr/local/bin/docker-compose

2、简单使用

　　创建compose工作目录

　　　　# mkdir composework

　　在compose工作目录内创建docker-compose.yml文件

　　　　# cat docker-compose.yml
　　　　tomcat1:
　　　　image: myweb:v2
　　　　ports:
　　　　- "9099:8080"
　　　　- "9093:8443"
　　　　volumes:
　　　　- ./websrc:/usr/local/tomcat/webapps/myproj
　　　　# tty: true
　　　　command: catalina.sh run

　　在.yml文件同级目录下创建websrc目录，存放tomcat源码文件

　　启动compose

# docker-compose up

3、Compose命令详解

　　

Compose命令详解：
build   #创建或者再建服务
help    #显示命令的帮助和使用信息
kill       #通过发送SIGKILL的信号强制停止运行的容器，这个信号可以选择性的通过，
#比如： docker-compose kill -s SIGKINT
logs    #显示服务的日志输出
port     #为端口绑定输出公共信息
ps        #显示容器
pull       #拉取服务镜像
rm        #删除停止的容器
run      #在服务上运行一个一次性命令
start    #启动已经存在的容器作为一个服务
stop     #停止运行的容器而不删除它们
up        #启动

docker-compose.yml命令说明：
image  #启动容器使用的镜像
build    #创建镜像，需要指定Dockerfile的目录
command   #重写默认的命令
links     #连接到其他服务中的容器
ports   #端口映射
volumes   #动态挂载路径
