Docker build with node Adapter failed with : Could not resolve entry module (index.html).
Describe the bug
Docker build with nodeAdapter '@sveltejs/adapter-node'; npm run build
npm run build works fine on the local machine without docker.
import adapter from '@sveltejs/adapter-auto';
import staticAdapter from '@sveltejs/adapter-static';
import nodeAdapter from '@sveltejs/adapter-node';
import preprocess from 'svelte-preprocess';
/** @type {import('@sveltejs/kit').Config} */
const config = {
// Consult https://github.com/sveltejs/svelte-preprocess
// for more information about preprocessors
preprocess: [
preprocess({
postcss: true
})
],
kit: {
adapter: getAdapter(),
// Override http methods in the Todo forms
methodOverride: {
allowed: ['PUT', 'PATCH', 'DELETE']
}
}
};
export default config;
function getAdapter() {
switch (process.env.ADAPTER) {
case 'node':
return nodeAdapter({
out: 'build/dist',
precompress: false
// default: HOST=0.0.0.0 PORT=3000
/*
env: {
host: 'HOST',
port: 'PORT'
}
*/
});
case 'static':
return staticAdapter({
pages: 'build/dist',
assets: 'build/dist',
fallback: 'index.html', // 404.html,
// trailingSlash: 'always'
});
default:
return adapter();
}
}

PS: same docker build was working before I updated sveltekit to the latest version.
Here is the minimal repo to reproduce docker build error
https://github.com/xmlking/svelte-starter-kit
This repo is created with npm create svelte@latest my-app
clone this repo and try to build docker image following doc https://github.com/xmlking/svelte-starter-kit/blob/main/docs/docker.md
my bad. I missed including the newly added /vite.config.ts file in my .dockerignore
after including /vite.config.ts, it worked as expected.
But the error message was weird. Could not resolve entry module (index.html). 🤯
