docker卷挂载问题

Question

Docker挂载目录问题（初学者）

dockerfile编写指定目录挂载会变成匿名挂载

VOLUME ["/home/ruoyi","/home/docker/ruoyi/gateway/logs:/home/ruoyi/logs/ruoyi-gateway"]

匿名挂载一个，指定挂载目录一个，查看挂载发现两个都是匿名的

"Mounts": [
            {
                "Type": "volume",
                "Name": "22c43fc3f90dc1410d628f0c84694f0418e15f4485eb5e6215081410da77a17b",
                "Source": "/var/lib/docker/volumes/22c43fc3f90dc1410d628f0c84694f0418e15f4485eb5e6215081410da77a17b/_data",
                "Destination": "logs:/home/ruoyi/ruoyi-gateway",
                "Driver": "local",
                "Mode": "",
                "RW": true,
                "Propagation": ""
            },
            {
                "Type": "volume",
                "Name": "ca62e97687616f41d65c094ac14bfda5cb8ff1b9bc6370fc8fc2ac1c0eef2353",
                "Source": "/var/lib/docker/volumes/ca62e97687616f41d65c094ac14bfda5cb8ff1b9bc6370fc8fc2ac1c0eef2353/_data",
                "Destination": "/home/ruoyi",
                "Driver": "local",
                "Mode": "",
                "RW": true,
                "Propagation": ""
            }
        ],

没办法，调整到docker-compose文件里面尝试挂载，发现竟然正常挂载了

volumes:
      - ./ruoyi/gateway/logs:/home/ruoyi/logs/ruoyi-gateway

"Mounts": [
            {
                "Type": "bind",
                "Source": "/home/docker/ruoyi/gateway/logs",
                "Destination": "/home/ruoyi/logs/ruoyi-gateway",
                "Mode": "rw",
                "RW": true,
                "Propagation": "rprivate"
            },
            {
                "Type": "volume",
                "Name": "3f9dc1604787e702bf8d49667f640c6859dde8f7bea515f1cc390f94f27ade8b",
                "Source": "/var/lib/docker/volumes/3f9dc1604787e702bf8d49667f640c6859dde8f7bea515f1cc390f94f27ade8b/_data",
                "Destination": "/home/ruoyi",
                "Driver": "local",
                "Mode": "",
                "RW": true,
                "Propagation": ""
            }
        ],

想请教各位同学，是什么原因我没学习到的地方？@哪 吒

Dockfile的挂载本身就是只能挂匿名，你在Dockerfile写相当于多路径 但是都是匿名挂载
