docker編寫(xiě)一個(gè)java應(yīng)用掛載殼子Dockerfile

1：Dockerfile文件

FROM openjdk:8-jre-slim
MAINTAINER xqf
ENV TZ Asia/Shanghai
RUN ln -snf /usr/share/zoneinfo/${TZ} /etc/localtime
EXPOSE 8082
ENTRYPOINT ["java", "-jar", "/opt/door/door-service-app-v2.0.0.jar","-Xss256k","-Xms2g","-Xmx4g","-XX:+UseG1GC"]

2：docker-compose.yml編排文件

version: '3.0'
services:
  hdx-door: 
    build:
     #這是指定dockerfile的文件路徑
      context: /opt/doorDocker
      dockerfile: Dockerfile
    image: hdx-door:latest
    container_name: hdx-door
    restart: always
    #如果和宿主機(jī)共用一個(gè)網(wǎng)絡(luò)，就不需要設(shè)置端口，不然就使用默認(rèn)網(wǎng)橋模式
    volumes:
      - /etc/localtime:/etc/localtime:ro
      - /opt/door:/opt/door:rw
    network_mode: host
