docker-compose 部署java微服务项目-JZTXT

1、准备条件：安装docker，安装docker-compose，docker安装可自行百度，docker-compose安装由于太慢，我这里提供两个版本：win和linux版本的百度网盘版，大家可根据需要自行下载：

这里一linux系统为例：下载docker-compose-linux-x86_64后上传到linux 的/usr/bin 下，然后使用 mv docker-compose-linux-x86_64 docker-compose 命名后，使用chmod +x docker-compose 赋予该文件执行权限，再复制一份到/usr/local/bin下，至此，你可以使用docker-compose --version 验证docker-compose是否安装ok

2、jar包准备：新建一个文件夹，如docker_images，将需要的jar 以文件夹 + jar + 该jar 的配置文件的形式，如spot-contract/spot-contract.jar 、spot-contract/application.yml，之后编写统一的Dockerfile文件：

FROM openjdk:8
WORKDIR /javaxh_docker/jdk
VOLUME /tmp
ARG JAR_FILE=./*.jar
ADD ${JAR_FILE} app.jar
ENTRYPOINT ["java", "-Dfile.encoding=UTF8", "-Duser.timezone=GMT+08", "-jar", "app.jar"]

将该Dockerfile复制一份到 spot-contract下，形成如下目录结构

|-docker_images

|----spot-contract

|--------spot-contract.jar

|--------Dockerfile

|--------application.yml

|----spot-base

|--------spot-base.jar

|--------Dockerfile

|--------application.yml

|----docker-compose.yml

使用docker build -t spot-contract:latest spot-contract/ 构建镜像

其他服务遵循同样的方式

3.编写docker-compose.yml

  fujian-network: { }
  mengxi-network: { }

4、服务的启动与关闭

docker-compose -f docker-compose.yml up -d 启动所有服务

docker-compose -f docker-compose.yml down 关闭所有服务

docker-compose -f docker-compose.yml up -d spot-base 只启动spot-base服务

docker-compose -f docker-compose.yml restart spot-base 重启spot-base服务

docker-compose -f docker-compose.yml start spot-base 启动spot-base服务（需要先执行过up操作）

docker-compose -f docker-compose.yml stop spot-base 停止spot-base服务

5、关于服务配置文件

eureka:
  client:
    serviceUrl:
      defaultZone: http://eureka-server:8761/eureka/
    healthcheck:
      enabled: true # 开启健康检查（需要spring-boot-starter-actuator依赖）,配置项必须设置在application.yml中
  instance:
    lease-renewal-interval-in-seconds: 30    # 续约更新时间间隔（默认30秒）
    lease-expiration-duration-in-seconds: 90 # 续约到期时间（默认90秒）

由于使用的是docker容器，docker-compose可通过服务名来通讯，也可使用127.0.0.1:映射到宿主机的端口访问
