I have a project developed by .NET 6 and React which when I publish it locally works successfully but when I use Dockerfile it gives this error:

I think node is not installed in the container. However, I added installation code to docker file:

FROM mcr.microsoft.com/dotnet/aspnet:6.0 AS base

RUN apt-get update -yq && apt-get upgrade -yq && apt-get install -yq curl git nano
RUN curl -sL https://deb.nodesource.com/setup_16.x | bash - && apt-get install -yq nodejs build-essential

WORKDIR /app
EXPOSE 80
EXPOSE 443

FROM mcr.microsoft.com/dotnet/sdk:6.0 AS build
WORKDIR /src

COPY ["psreactnet.csproj", "."]
RUN dotnet restore "./psreactnet.csproj"
COPY . .
WORKDIR "/src/."
RUN dotnet build "psreactnet.csproj" -c Release -o /app/build



FROM build AS publish
RUN dotnet publish "psreactnet.csproj" -c Release -o /app/publish

FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .
ENTRYPOINT ["dotnet", "psreactnet.dll"]

How can I install node in the container?

CodePudding user response：

publish stage doesn't have base stage. Try install node in build stage

try adding RUN apt-get... and RUN curl -sL de... after "as build" stage

#base stage
FROM mcr.microsoft.com/dotnet/aspnet:6.0 AS base
...

#build stage
FROM mcr.microsoft.com/dotnet/sdk:6.0 AS build

RUN apt-get update -yq && apt-get upgrade -yq && apt-get install -yq curl git nano
RUN curl -sL https://deb.nodesource.com/setup_16.x | bash - && apt-get install -yq nodejs build-essential


WORKDIR /src
