Docker compose with tanstack start

[thibaultdenis014]

Hey guys,

I am struggling to get docker working with tanstack start in DEV mode ? I keep getting this error. I have tried to play around with the host name but with no luck:

Reproduction steps:

• follow the build from scratch guide from the docs here
• copy the dev.Dockerfile and docker-compose below.
• run docker compose up

Here is what my dev.Dockerfile looks like:

FROM node:22-alpine

WORKDIR /app

COPY package.json pnpm-lock.yaml* ./

RUN corepack enable pnpm && pnpm i

COPY . .

CMD ["pnpm", "dev"]

And my docker-compose file:

services:
  server:
    container_name: my_container
    build:
      context: ./
      dockerfile: dev.Dockerfile
    env_file:
      - .env
    volumes:
      - ./:/app
    ports:
      - 3000:3000

I have the same problem. HMR does not work in Docker, but it works outside of it.

It seems that vinxi doesn't allow you to configure the underlying vite hmr options needed to get this to work in Docker. I suspect I need to set vite.server.hmr.host to '0.0.0.0' and/or vite.server.hmr.port to a static port that's mapped in the Docker compose file. nksaraf/vinxi#394 is an FR to allow HMR ports to be configurable.

I have tried to play around with the host name but with no luck

How are you changing the host name? I couldn't figure out how to configure this.

I tried to set it in the docker compose like so with no luck:

.....
  server:
    container_name: gym_graphs_server
    hostname: 0.0.0.0
.....

Vinxi 0.5.4 now allows this setting. How do I configure it in my Tanstack Start project though? nksaraf/vinxi#465
