Docker file with asp.net throws npm not found error while it is building in Jenkins-CodePudding

I am trying to build docker file below through Jenkins.

FROM mcr.microsoft.com/dotnet/sdk:2.1 AS build

ARG PROFILE=Production

WORKDIR /app
COPY . ./

RUN cd src/stayfolio.Demo.Web.aroundfollie \
    && npm install && npm run build:dll && npm start

RUN dotnet restore stayfolio.Demo.Web.sln \
    && cd src/stayfolio.Demo.Web.aroundfollie \
    && mkdir -p build/outputs/aroundfollie \
    && dotnet publish --output ../../build/outputs/aroundfollie/

FROM mcr.microsoft.com/dotnet/sdk:2.1

WORKDIR /app
COPY --from=build /app/build/outputs/aroundfollie ./

CMD ["dotnet", "stayfolio.Demo.Web.aroundfollie.dll"]

However while building the file, it gives an error saying

step 5/10 : RUN cd src/stayfolio.Demo.Web.aroundfollie && npm install && npm run build:dll && npm start ---> Running in 86a2e1e8efcf [91m/bin/sh: 1: npm: not found [0mThe command '/bin/sh -c cd src/stayfolio.Demo.Web.aroundfollie && npm install && npm run build:dll && npm start' returned a non-zero code: 127

as you can see my docker file, I mentioned && npm install && npm run build:dll && npm start, but why the error saying npm: not found?

CodePudding user response：

By default, the docker image mcr.microsoft.com/dotnet/sdk does not have npm installed. You can install it with the package manager or copy it from another docker image.

Example:

FROM node:alpine AS node_base
FROM mcr.microsoft.com/dotnet/sdk:2.1 AS build
COPY --from=node_base . .
# the rest of your Dockerfile

This approach is also described in the article you mentioned in your comment How to integrate 'npm install' into ASP.NET CORE 2.1 Docker build
