docker compose的使用

因当前未安装适合的docker管理界面，每次启动docker容器时都是一长串的命令，悲催的是我自己也记不住。

看到同道中人使用 docker compose，尝试使用

1. 安装docker compose
   yum install python-pip.noarch
   pip install --upgrade pip
   pip install docker-compose

[root@localhost ~]# docker-compose -v
docker-compose version 1.8.0, build 94f7016

2. 配置docker compose
   启动命令

#docker run --name=$HOSTNAME-house --restart=always -d -ti -p 18080:8080 -v /opt/product/data/financeDcmsCollect:/opt/product/data  house:v1.0

改成docker-compose.yml

version: '2'
services:
     financecollect:
       image: financecollect:20170111
       container_name: house
       restart: always
       ports:
         - 18080:8080
       volumes:
         - /opt/product/data/financeDcmsCollect:/opt/product/data

3. 启动

docker-compose up -d
#创建并启动容器

4. 停止

docker-compose down 
#停止并删除容器

不用担心记不住命令啦，很实用的一个工具。

[root@localhost ~]# docker-compose --help
Define and run multi-container applications with Docker.

Usage:
  docker-compose [-f <arg>...] [options] [COMMAND] [ARGS...]
  docker-compose -h|--help

Options:
  -f, --file FILE             Specify an alternate compose file (default: docker-compose.yml)
 # 为了区分需要操作的镜像，个人觉得可改成 镜像名.yml ，然后用-f指定文件名。
  -p, --project-name NAME     Specify an alternate project name (default: directory name)
  --verbose                   Show more output
  -v, --version               Print version and exit
  -H, --host HOST             Daemon socket to connect to

  --tls                       Use TLS; implied by --tlsverify
  --tlscacert CA_PATH         Trust certs signed only by this CA
  --tlscert CLIENT_CERT_PATH  Path to TLS certificate file
  --tlskey TLS_KEY_PATH       Path to TLS key file
  --tlsverify                 Use TLS and verify the remote
  #以上tls暂时都未用到
  --skip-hostname-check       Don't check the daemon's hostname against the name specified
                              in the client certificate (for example if your docker host
                              is an IP address)
