通过Docker Compose来实现项目可以指定读取不同环境的yml包

1. 配置文件
2. 启动命令
切换不同环境
注意挂载的文件权限要777

1. 配置文件

在这里插入图片描述

version: '3.8'
services:
  docker-test:
    image: openjdk:8-jdk-alpine
    ports:
      - "${APP_PORT}:${CONTAINER_PORT}"
    volumes:
      - "${JAR_PATH}:/app/docker-test.jar"
      - "${APPLICATION_YML}:/app/config/application.yml"
      - "${APPLICATION_DEV_YML}:/app/config/application-dev.yml"
      - "${APPLICATION_PROD_YML}:/app/config/application-prod.yml"
      - "${LOGS_PATH}:/app/logs"
    environment:
      - SPRING_PROFILES_ACTIVE=${SPRING_PROFILES_ACTIVE}
    command: >
      sh -c "java -jar /app/docker-test.jar > /app/logs/log.out 2>&1"
    restart: always

# env文件
# 配置文件路径
CONFIG_PATH=./

# 应用程序配置文件
APPLICATION_YML=${CONFIG_PATH}/application.yml
APPLICATION_DEV_YML=${CONFIG_PATH}/application-dev.yml
APPLICATION_PROD_YML=${CONFIG_PATH}/application-prod.yml

# Spring Profile (可以是 dev、prod 或其他配置)
SPRING_PROFILES_ACTIVE=dev

# 端口映射
APP_PORT=1888
CONTAINER_PORT=9898
JAR_PATH=./docker-test-0.0.1-SNAPSHOT.jar
LOGS_PATH=./logs

2. 启动命令
