Cannot find 'nuxt.mjs' during build in Dockerfile

Hey all, I'm trying to build my Nuxt application via Docker, but my Dockerfile is giving me the following error:

This is my Dockerfile: 
ARG NODE_VERSION=22.14.0

FROM node:${NODE_VERSION}-slim AS build

ENV PNPM_HOME="/pnpm"
ENV PATH="$PNPM_HOME:$PATH"
RUN corepack enable

WORKDIR /app

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

RUN pnpm install --shamefully-hoist

COPY . ./

RUN pnpm run build

FROM node:${NODE_VERSION}-slim

WORKDIR /app

COPY --from=build /app/.output ./

ENV HOST=0.0.0.0 NODE_ENV=production
ENV NODE_ENV=production

EXPOSE 3000

CMD ["node", "/app/server/index.mjs"]
ARG NODE_VERSION=22.14.0

FROM node:${NODE_VERSION}-slim AS build

ENV PNPM_HOME="/pnpm"
ENV PATH="$PNPM_HOME:$PATH"
RUN corepack enable

WORKDIR /app

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

RUN pnpm install --shamefully-hoist

COPY . ./

RUN pnpm run build

FROM node:${NODE_VERSION}-slim

WORKDIR /app

COPY --from=build /app/.output ./

ENV HOST=0.0.0.0 NODE_ENV=production
ENV NODE_ENV=production

EXPOSE 3000

CMD ["node", "/app/server/index.mjs"]
Building locally seems to work just fine, so I'm not sure what's causing this issue. Any help would be appreciated!

Hi @Viridian. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Based on the error message and your Dockerfile, I can see you're encountering a common issue when building Nuxt applications in Docker. The error indicates that Docker can't find the nuxt.mjs file during the build process. Looking at the knowledge sources, there are a few potential solutions: Missing .dockerignore file The most likely cause is that you're missing a .dockerignore file, which is causing your local node_modules folder to be copied over and interfering with the Docker build process. This exact issue was mentioned in a Stack Overflow post where the solution was adding a proper .dockerignore file Stack Overflow Post > Docker Build Problem "Error: Cannot find module". Create a .dockerignore file in the same directory as your Dockerfile with the following content: 
node_modules
npm-debug.log
.nuxt
.output
node_modules
npm-debug.log
.nuxt
.output
Other potential solutions If adding the .dockerignore file doesn't solve your issue, consider these alternatives: 1. Use shamefully-hoist=true: In one of the knowledge sources, it was mentioned that some Nuxt modules might not work without the shamefully-hoist flag. You're already using this in your Dockerfile, which is good. 2. Try a different package manager: Some users reported success by switching from one package manager to another. If pnpm continues to cause issues, you might try npm or yarn. 3. Use buildx for cross-platform builds: If you're building for a different platform than your host, using docker buildx build instead of docker build might help, as mentioned in Stack Overflow Post > Nuxt build hanging when building in linux docker image. 4. Check your Nuxt version compatibility: Make sure your Nuxt version is compatible with the Node.js version you're using in your Dockerfile. Let me know if adding the .dockerignore file resolves your issue! ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
