File mounts in Compose do not work

[luixo]

To Reproduce

1. Create a Compose
2. Go to Advanced tab, Volumes
3. Add a new File Mount (others are not available), note that you can't choose Mount Path (though you can forge a request to change it via HTTP)
4. Redeploy your compose
5. Open compose shell

Current vs. Expected behavior

Expected: file is mounted (not sure where should it mount with / Mount Path, but I did change it via HTTP and still couldn't find it)
Actual: file can't be found nowhere

Provide environment information

Dokploy version: v0.24.12

Which area(s) are affected? (Select all that apply)

Docker Compose

Are you deploying the applications where Dokploy is installed or on a remote server?

Same server where Dokploy is installed

Additional context

Inspecting Docker container, I didn't find any mounts. Not sure that's how it's done though, I'm not proficient enough with Docker.

Let me know where's the logic for fecthing mounts and wiring them up to the compose file, I might fix it.

Will you send a PR to fix it?

Yes

Can you paste your docker compose?

This is the one I get from "preview compose":

services:
  soketi:
    image: quay.io/soketi/soketi:1.4-16-debian
    restart: always
    command:
      - node
      - /app/bin/server.js
      - start
      - '--config=/external/config.json'
    environment:
      SOKETI_DEBUG: ${SOKETI_DEBUG:-0}
      SOKETI_HOST: 0.0.0.0
    ports:
      - '6001'
    networks:
      - dokploy-network

This is the one I pasted into the textarea:

    command: [ "node", "/app/bin/server.js", "start", "--config=/external/config.json" ]
    environment:

I don't see anywhere where you are using a file mount.

Here is an example of a plausible template where file mounts are used: https://github.com/Dokploy/templates/blob/main/blueprints/plausible/docker-compose.yml and template.toml https://github.com/Dokploy/templates/blob/main/blueprints/plausible/template.toml

You can use the same idea. We also mention how to use file mounts in the documentation https://github.com/Dokploy/templates/blob/main/blueprints/plausible/template.toml

Let me explain myself.

Application service

In an "application" type of a service, I can add a volume that results in a UI that looks like this:

In docker inspect <container> in HostConfig I see:

"Mounts": [
    {
        "Type": "bind",
        "Source": "/etc/dokploy/applications/<appname>/files/test.txt",
        "Target": "/external"
    }
],

and in service root:

"Mounts": [
    {
        "Type": "bind",
        "Source": "/etc/dokploy/applications/<appname>/files/test.txt",
        "Destination": "/external",
        "Mode": "",
        "RW": true,
        "Propagation": "rprivate"
    }
],

Compose service

On the other hand, in "compose" type of a service I also can add a volume that results in a UI that looks pretty similar:

But in docker inspect <container> in service root I see:

"Mounts": [],

While in HostConfig there is nothing at all.

The question

What this "File Mount" volume is for in the "compose" service?

[Siumauricio]

Again, the idea behind file mounts is that you reference them exactly as we mentioned here. Applications are somewhat different from compose. Mounts are mounted internally in the container, but in compose, if you do not reference the file mounts in your Docker Compose file, they will never appear.

[luixo]

I think the interface is misleading in this case.
I'd expect Mount Path to show me where files are mounted in the container, but it doesn't. Other way around, it could be omitted and link to this documentation / explicit text on mounting should be added.

I see 2 good solution from here:

• Let user modify Mount Path and auto-mount files as it's done on Application type of a service
• Add info in the UI about mounting volumes so there's no confusion
