获取类型为“bind”的无效mount配置：docker中不存在绑定源路径

导读：我正在尝试将以下docker-compose部署到docker swarm集群中. version: '3.2'services: jenkins: image: jenkins/jenkins:lts ports: - 8080:8080 volumes: - ./data_jenkins:/var/jenkins_home deploy: mode: replicated replicas: 1 我确实在docker-compose

我正在尝试将以下docker-compose部署到docker swarm集群中.

version: '3.2'
services:
  jenkins:
    image: jenkins/jenkins:lts
    ports:
      - 8080:8080
    volumes:
      - ./data_jenkins:/var/jenkins_home
    deploy:
      mode: replicated
      replicas: 1

我确实在docker-compose所在的相同位置有data_jenkins,并将该路径作为卷传递.但为什么抛出源路径不存在.究竟是什么问题.

Also if the directory doesnot exist -v should have created it right.
Why is it not ?

解决方法

这在 Docker Swarm BIND MOUNTS中有明确记载

If you bind mount a host path into your service’s containers,the path
must exist on every swarm node. The Docker swarm mode scheduler can
schedule containers on any machine that meets resource availability
requirements and satisfies all constraints and placement preferences
you specify.

与运行单个容器不同,如果不退出,则不会创建绑定装载主机目录.它必须在群集节点上运行容器之前存在.
