Docker + nodejs - JavaScript heap out of memory

[RicardoGaefke]

• Node.js Version: 12.15.0-r1
• OS: Linux Alpine
• Scope (install, code, runtime, meta, other?): npm run production
• Module (and version) (if relevant):

I have a .NET Core & SSR React app and everything runs fine on my computer and on Azure Pipelines and Azure Win and Linux WebApps but when I try to build a Docker Image I always receive 'JavaScript heap out of memory'.

Here is my Dockerfile:

FROM mcr.microsoft.com/dotnet/core/sdk:3.0-alpine AS build

RUN apk add --no-cache bash git openssh nodejs npm

RUN git clone -b dev https://github.com/RicardoGaefke/profile4d.git ./app

WORKDIR /app/src/Web.Identity

RUN NODE_OPTIONS=--max_old_space_size=32768‬

RUN npm install

RUN npm run lint-fix

RUN npm run production1

RUN dotnet publish -c Release ./Web.Identity.csproj -r linux-musl-x64 -o ./publish

FROM mcr.microsoft.com/dotnet/core/runtime-deps:3.0-alpine as runtime

EXPOSE 80

WORKDIR /app

COPY --from=build /app/src/Web.Identity/publish ./

ENTRYPOINT ["dotnet", "Web.Identity.dll"]

And this is my build command:

docker build -f .\Dockerfile.web.identity.cloud -t web_identity_cloud .

Can anybody please help me?

Thank a lot.

You should scrap that line unless your docker image really has over 32 GB of memory available to it.

Thank you for your reply. I made it work here making more cores and memory available for docker (in docker settings). And my final file that runs both local and on my Azure Pipelines is:

FROM mcr.microsoft.com/dotnet/core/sdk:3.0-alpine AS build

RUN apk update && apk add --no-cache bash git openssh nodejs npm

RUN git clone -b staging https://github.com/RicardoGaefke/profile4d.git ./app

WORKDIR /app/src/Web.Identity

RUN npm install

RUN npm run lint-fix

RUN npm run production

RUN dotnet publish -c Release ./Web.Identity.csproj -r linux-musl-x64 -o ./publish

FROM mcr.microsoft.com/dotnet/core/runtime:3.0-alpine as runtime

RUN apk update && apk add --no-cache nodejs npm nodejs-npm

RUN export PATH=$PATH:/usr/bin/node:/usr/share/doc/nodejs

ENV ASPNETCORE_URLS=http://+:5000

WORKDIR /app

COPY --from=build /app/src/Web.Identity/publish ./

ENTRYPOINT ["./Web.Identity"]

Again, thank you very much.
