Details

As of v1.1.1, rspack does not successfully build in Docker containers. This bug is not present in rspack v1.1.0, or when installing directly on the host machine.

Reproduce Steps

1. Clone the example repo
2. Start a docker daemon
3. docker build . -f Dockerfile-rspack -t rspack-image
4. Observe the error below

ERROR in × Module not found: Can't resolve './src/index' in '/app'
help: Found module './src/index.js'. However, it's not possible to request this module without the extension
      if its extension was not listed in the `resolve.extensions`. Here're some possible solutions:

      1. add the extension `".js"` to `resolve.extensions` in your rspack configuration
      2. use './src/index.js' instead of './src/index'

Compare to building directly on the host machine, which works fine:

npm ci
npm run build:rspack

Builds in Docker also work in v1.1.0. To demonstrate, downgrade the rspack binaries and try to build the Docker image again:

npm i -DE @rspack/cli@1.1.0 @rspack/core@1.1.0
docker build . -f Dockerfile-rspack -t rspack-image

The same issue is occurring on Cloudflare Pages. Although I haven’t changed the code, after updating rspack from v1.1.0 to v1.1.1, a "module not found" error started appearing. Building locally works without any issues.

We have a similar issue with @rsbuild/core: 1.1.1 also, probably related? Rolling back to @rsbuild/core: 1.0.19 that uses @rspack/core: 1.0.14 fixes the issue

I also have the same problem.
我也有同样的问题。
🤣

Running into a similar problem with Docusaurus. However, Docusaurus is only dependent on @rspack/core@1.0.14. Instead, I have to explicitly resolve @rspack/binding@1.0.14.

We have a similar issue with @rsbuild/core: 1.1.1 also, probably related? Rolling back to @rsbuild/core: 1.0.19 that uses @rspack/core: 1.0.14 fixes the issue

@rsbuild/core depends on @rspack/core, which in turn depends on @rspack/binding@1.0.14. Since this seems to be the only package I have issues with, I assume this internal package (or more likely, one of its optional dependencies) is causing these issues.

same for me Rolling back to @rsbuild/core: 1.0.19 solve issue

Works for linux-x64-gnu, but fails for linux-x64-musl. That is, using an node:18-alpine image which uses musl fails, but if I use node:18-bullseye which uses gnu, it works fine.

If I may believe my yarn.lock, these are the possible different bindings:

  optionalDependencies:
    "@rspack/binding-darwin-arm64" "1.1.1"
    "@rspack/binding-darwin-x64" "1.1.1"
    "@rspack/binding-linux-arm64-gnu" "1.1.1"
    "@rspack/binding-linux-arm64-musl" "1.1.1"
    "@rspack/binding-linux-x64-gnu" "1.1.1"
    "@rspack/binding-linux-x64-musl" "1.1.1"
    "@rspack/binding-win32-arm64-msvc" "1.1.1"
    "@rspack/binding-win32-ia32-msvc" "1.1.1"
    "@rspack/binding-win32-x64-msvc" "1.1.1"

we are using node:20.11.1-alpine3.18 and its failing

[chenjiahan]

Pin @rspack/core to 1.1.0 should fix this.

For example, use pnpm overrides:

// package.json
{
  "pnpm": {
    "overrides": {
      "@rspack/core": "1.1.0"
    }
  }
}

for us it's a problem with "tsconfig.json". Rspack do not see this file at all in docker with node:20.5.0-alpine to node:23.1.0-alpine. changing location of a file in docker container does not resolve the issue.
