docker与docker-compose从项目角度出发查看异同

标签：core compose 异同 harbor registry docker root


docker

是一个供开发和运维人员开发，测试，部署和运行应用的容器平台。这种用linux container部署应用的方式叫容器化。
http://mirrors.163.com/docker-ce/linux/static/stable/x86_64/

 docker-compose

是一个用于运行和管理多个容器化应用的工具(一系列的容器)
https://github.com/docker/compose/releases/download/1.29.2/docker-compose-Linux-x86_64
https://github.com/docker/compose/releases/  #有各种版本

docker和 docker-compose二者对比下：

1.docker是自动化构建镜像，并启动镜像。 docker compose是自动化编排容器。
2.docker是基于Dockerfile得到images,启动的时候是一个单独的container
3.docker-compose是基于docker-compose.yml,通常启动的时候是一个服务，这个服务通常由多个container共同组成，并且端口，配置等由docker-compose定义好。
4.两者都需要安装，但是要使用docker-compose，必须已经安装docker

docker应用实例:

# centos7
# 从阿里云直接下载docker-ce.repo文件
[root@centos7 ~]#wget -P /etc/yum.repos.d/ https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
[root@centos7 ~]#yum repolist 
[root@centos7 ~]#yum list docker-ce* --showduplicates | sort -r
[root@centos7 ~]#yum -y install docker-ce-19.03.13-3.el7 docker-ce-cli-19.03.13-3.el7
# centos安装完后需要手动启动docker
[root@centos7 ~]#systemctl enable --now docker

#查看版本，验证安装成功
[root@centos7 ~]#docker --version
Docker version 19.03.13, build 4484c46d9d

以下docker-compose是重点

docker-compose应用实例(用docker-compose方式管理harbor):

 

docker ps 启动的容器,都是harbor相关的一系列容器

首先安装docker-compose : wget https://github.com/docker/compose/releases/download/1.29.2/docker-compose-Linux-x86_64

harbor相关维护命令：
＃启动Harbor

# docker-compose start
停止Harbor
# docker-comose stop
重启Harbor
# docker-compose restart

#################################################################

启动 harbor
docker-compose up -d

关闭 harbor
docker-compose down -v

#################################################################

查看状态

docker-compose ps

查看 log
/var/log/harbor
###在harbor.cfg中设定

#################################################################

在Harbor安装完成之后，在此目录下会生成 docker-compose.yml 配置文件，可以使用docker-compose操作此文件来控制Harbor的启停。

#docker-compose down

##加载配置文件
./prepare
###启动所有后台所有服务
docker-compose up -d

 docker-compose配置文件 docker-compose.yml 创建harbor仓库,相关文件

[root@fp-web-169 harbor]# locate docker-compose
