Docker从入门到精通<8>-docker-compose任务编排

前面我们讲了docker创建,使用,管理,但是如果容器一个一个的去创建将会变得非常的繁琐. 所以docker的编排工具就应运而生了, 比如docker-compose,swarm,mesos,kubernetes 等，这里我们不对docker-compose做深入的研究，后面我们直接使用kubernetes进行任务编排。

安装

安装稳定版

# 下载docker-compose
sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

# 添加执行权限
sudo chmod +x /usr/local/bin/docker-compose

1. 通过docker-compose安装zabbix-server

下载zabbix docker-compose的仓库包，这里我们下载最新的版本zabbix-docker-5.4，如果你连不上github可以从我这里下载，点这里

unzip zabbix-docker-5.4.zip
cd zabbix-docker-5.4
docker-compose -f docker-compose_v3_centos_mysql_latest.yaml up -d

2. 检查

[root@vm0 zabbix]# docker ps
CONTAINER ID   IMAGE                                             COMMAND                  CREATED          STATUS                    PORTS                                                                            NAMES

3. 尝试打开页面，需要等待一会儿
   

4. 我们简单看下zabbix docker-compose
