docker-compose怎么用

這篇文章給大家分享的是有關docker-compose怎么用的內容。小編覺得挺實用的，因此分享給大家做個參考，一起跟隨小編過來看看吧。

The Compose file is a YAML file defining services, networks and volumes. A service definition contains configuration that is applied to each container started for that service, much like passing command-line parameters to docker run. Likewise, network and volume definitions are analogous to docker network create and docker volume create.As with docker run, options specified in the Dockerfile, such as CMD, EXPOSE, VOLUME, ENV, are respected by default - you don’t need to specify them again in docker-compose.yml.

文檔上這段話已經概括了docker-compose編排文件的寫法。一個yaml的編排文件定義了 services, networks and volumes，service定義的配置其實就是docker run命令的參數，同理network and volume定義的是docker network create，docker volume create命令，在dockerfile文件中有的諸如CMD, EXPOSE, VOLUME, ENV命令則不需要重新定義。剩下的需要什么找什么命令就好了。

一個例子：

創建一個名為kong-net，橋接模式的network，將3個容器加入進來，其中kong容器是使用dockerfile構建，db和konga使用遠程倉庫鏡像，kong的啟動在db之后，konga的啟動在kong之后。

version: '3'
services:
  kong:
    container_name: kong-dapeng
    environment:
      - KONG_DATABASE=postgres
      - KONG_PG_HOST=kong-database
      - KONG_PG_PASSWORD=kong
      - KONG_PROXY_ACCESS_LOG=/dev/stdout
      - KONG_ADMIN_ACCESS_LOG=/dev/stdout
      - KONG_PROXY_ERROR_LOG=/dev/stderr
      - KONG_ADMIN_ERROR_LOG=/dev/stderr
      - KONG_ADMIN_LISTEN=0.0.0.0:8001, 0.0.0.0:8444 ssl
      - KONG_PLUGINS=bundled,router-by-jwt-claim,jwt-dapeng,kafka-log
    build: .
    ports:
      - "80:8000"
      - "8001:8001"
    networks:
      - kong-net
    depends_on:
      - db
  db:
    container_name: kong-database
    image: "postgres:9.6"
    ports:
      - "5432:5432"
    environment:
      - POSTGRES_USER=kong
      - POSTGRES_DB=kong
      - POSTGRES_PASSWORD=kong
    volumes:
      - /dockerV/postgres:/var/lib/postgresql/data
    networks:
      - kong-net
  konga:
    container_name: konga
    image: "pantsel/konga"
    ports:
      - "1337:1337"
    environment:
      - DB_ADAPTER=postgres
      - DB_HOST=kong-database
      - DB_PORT=5432
      - DB_USER=kong
      - DB_PASSWORD=kong
      - DB_DATABASE=konga
    networks:
      - kong-net
    depends_on:
      - kong
networks:
  kong-net:
    driver: bridge
