docker-compose 是什么

熟悉docker的人都知道Dockerfile用來(lái)構(gòu)件單個(gè)鏡像服務(wù)的偏窝，想要運(yùn)行服務(wù)校焦，要輸入復(fù)雜的 run 命令來(lái)啟動(dòng)并配置服務(wù)运吓。
對(duì)于服務(wù)間依賴以及服務(wù)的環(huán)境變量跌穗、網(wǎng)絡(luò)參數(shù)佃声、文件掛載等操作偷霉，當(dāng)然可以使用yaml文件來(lái)配置迄委，這就是docker-compose
docker-compose 就是Docker編排工具，可以優(yōu)雅的配置服務(wù)間的依賴關(guān)系腾它，服務(wù)的屬性控制跑筝，減少運(yùn)維成本。

docker-compose 安裝 redis單節(jié)點(diǎn)

目錄結(jié)構(gòu)

redis
├─ docker-compose.yml
└─ redis.conf

• ./redis.conf redis單節(jié)點(diǎn)服務(wù)配置文件
• ./docker-compose.yml docker-compose配置文件

redis單節(jié)點(diǎn) docker-compose.yml 文件

version: '3'
services:
   redis:
     image: redis:latest
     restart: "no"
     container_name: redis
     ports:
       - "5070:6379"
     volumes:
       - ./redis.conf:/etc/redis/redis.conf 
       - ./data:/data      
     command: redis-server /etc/redis/redis.conf 
     privileged: true

• image 服務(wù)使用的鏡像
• restart: always/no 保持無(wú)服務(wù)開(kāi)機(jī)啟動(dòng)或者其他情況下正常啟動(dòng)/不自動(dòng)啟動(dòng)
• volumes 掛載外部路徑到容器內(nèi)部
• ports 暴露服務(wù)內(nèi)部端口
• ./docker-compose.yml docker-compose配置文件

啟動(dòng)服務(wù)

執(zhí)行命令啟動(dòng)服務(wù) docker-compose up -d

等待success提示則=啟動(dòng)成功

服務(wù)啟動(dòng)成功瞒滴，就可以使用訪問(wèn)redis單節(jié)點(diǎn)服務(wù)了
