Docker on remote host: How to bind volumes correctly

Hello,

i want to work with docker on a remote host. I can connect to the remote docker daemon and almost everything works fine!

Docker settings:

Remote Interpreter:

I seems like that i have a problem in my mappings which i dont understand. Files dont appear in my /var/www/html folder in my container on the remote machine.

I tried volume binding like i did when i had docker installed locally on my laptop ( which did not work obviously )

Because this maps the docker container /var/www/html folder to /Users/martin/PhpstormProjects/dev2.0 on the remote host but not on m laptop

The question is: How can i bind my local folder on my Laptop with the /var/www/html folder in my docker container on my remote machine? I don`t get it.

thank you very much!

@..., could you please tell more about your case?
Do you have a Docker Compose or a simple Docker configuration? What does not work exactly?

Hi Vasiliy Yur

I'm trying to use docker remote via ssh. the connection is working properly.

it's my docker config

but when I run my container like

version: '3.8'
services:
  api:
    image: nginx:1.17
    volumes:
      - ./api:/app
      - ./api/.docker/nginx/nginx.conf:/etc/nginx/nginx.conf
    ports:
      - "8000:80"
    links:
      - php

it's returning this error

Error response from daemon: OCI runtime create failed: container_linux.go:370: starting container process caused: process_linux.go:459: container init caused: rootfs_linux.go:59: mounting "/Users/erison.silva/Projects/myprofile/api/.docker/nginx/nginx.conf" to rootfs at "/var/lib/docker/overlay2/377268b48376ad5e82acbda1e2886f3b86781de298567396c35eeb1a9df46ec4/merged/etc/nginx/nginx.conf" caused: not a directory: unknown: Are you trying to mount a directory onto a file (or vice-versa)? Check if the specified host path exists and is the expected type

and I saw that it's creating the same path in my remote server like "Users/....."

and nothing is mapped to the correct folder

Hey @...,

Thanks for the explanation. I have played around with the SSH remote Docker installation and may confirm a similar behaviour. What happens here is that it tries to mount your "./api" volume in your Docker Compose file not from a remote SSH server but from the workstation where IDE is running. In case of Windows client + remote SSH Linux Docker machine, things are even worse:

Not sure if there is any workaround for now apart from having a copy of mounted volumes on your remote Docker server and specifying a full path in YML config file, like:

```

 volumes:
      - /home/user/projects/test/api:/app
      - /home/user/projects/test/:/etc/nginx/nginx.conf
