执行docker-compose.yaml报错Error: Unable to access jarfile_docker-compose error: unable to access jarfile

问题描述

我有如下docker-compose.yaml文件

version: '2'
services:
  workQueueService:
    restart: always
    image: openjdk:11.0.4
    ports:
      - "11100:11100"
    container_name: "haihu-workQueueService"
    user: root
    privileged: true
    volumes:
      - /data/docker/InternetHospitals/haihu-workQueueService:/var/haihu
      - /data/haihu/resources:/data/haihu/resources
    environment:
      TZ: "Asia/Shanghai"   #时区
    working_dir: /var/haihu
    command: java -server  -Xmx512m -XX:+UseG1GC  -jar /data/docker/InternetHospitals/haihu-workQueueService/target/haihu-workQueueService-0.0.1-SNAPSHOT.jar

我执行docker-compose up 时却一直报错：

Error: Unable to access jarfile /data/docker/InternetHospitals/haihu-workQueueService/target/haihu-workQueueService-0.0.1-SNAPSHOT.jar

原因分析：

1.权限不足：

修改为777后依然报错

2.映射路径错误

version: '2'
services:
  workQueueService:
    restart: always
    image: openjdk:11.0.4
    ports:
      - "11100:11100"
    container_name: "haihu-workQueueService"
    user: root
    privileged: true
    volumes:
      - /data/docker/InternetHospitals/haihu-workQueueService:/var/haihu
      - /data/haihu/resources:/data/haihu/resources
    environment:
      TZ: "Asia/Shanghai"   #时区
    working_dir: /var/haihu
    command: java -server  -Xmx512m -XX:+UseG1GC  -jar /data/docker/InternetHospitals/haihu-workQueueService/target/haihu-workQueueService-0.0.1-SNAPSHOT.jar

图中的
- /data/docker/InternetHospitals/haihu-workQueueService:/var/haihu 这一行表示将宿主机中的项目 挂载到容器内的/var/haihu中
所以最后一行jar包的路径应该为 command: java -server -Xmx512m -XX:+UseG1GC -jar /var/haihu/target/haihu-workQueueService-0.0.1-SNAPSHOT.jar jar包路径改为为容器内 的targetjar包路径
