--watch is not reloading when host file changes

[devansvd]

I passed the --watch argument.

when db.json file changes in host machine the changes also obviously reflects inside docker container /data/db.json since volume mounted. But it still supplies the old db.json values.

The file is changed Right ?

When Post through curl it works properly. Restarting docker container it works properly.

Changing file directly not working (--watch)

Any updates?

Any updates?

It works, please look at this

version: '3.6'
services:
  json:
    image: clue/json-server
    volumes:
      - ./json-server:/data/
    command: --watch

I can't get it to work by passing --watch to the end of the docker run command. But if I run the example with --help it outputs the help so the arguments seem to be passed fine. Very strange.

I think the reason this is not working for some is due to the volume mount directly on the db.json file. If you mount on the directory instead it should work. Possibly this has something to do with the way that json-server is writing updates to the file. It might be doing something that is causing the inode bind-mount to break. This is a known issue with file-mounts. See this comment https://github.com/moby/moby/issues/15793#issuecomment-135411504.

This works for me:

docker run -d -p 80:80 -v $PWD/data:/data clue/json-server --watch

TL;DR - if you are using windows, do not use WSL2 backend in order for the sync to work. See: https://github.com/docker/for-win/issues/8479

In case you are trying to change the file from a windows box and have json-server automatically sync it and display the correct file - it might not work depending on the docker version you are using and whether you are using WSL2 engine.

I have tried it using docker desktop 3.2.2. It did not work using the Dockerfile from this repo and my own Dockerfile. It works perfectly well on my ubuntu box - same setup, same commands.

The interesting part is if you do docker exec -it .. /bin/sh you will see that the file actually is updated, however json-server does not pick up the changes when using windows machine. After switching the WSL2 engine off (going back to Hyper-V) it started working perfectly! See: https://github.com/docker/for-win/issues/8479

Thank you for your response but please I need help. Here is my docker compose file but I'm still not getting hot reload. I'm using docker desktop on windows 11 wsl 2 ubuntu distros
