Docker Node Alpine Image Build Fails on node-gyp

Docker node:7.9-alpine unable to build package due python is not installed :Resolved

I'm attempting to Dockerize a node.js application(Typescript). I'm using the node:12.18.4-alpine Docker image as a base.

I go this

gyp ERR! configure error

my docker file was

 #MY first stage, that is the Builder
FROM node:12.18.4 AS ts-sample-builder
WORKDIR /app
COPY . .
RUN npm install
RUN npm run clean
RUN npm run build
# My Second stage, that creates an image for production
FROM node:12.18.4 AS ts-sample-prod
WORKDIR /app
COPY --from=ts-sample-builder ./app/dist ./dist
COPY package* ./
RUN npm install --production
CMD npm run start-prod
EXPOSE 3001

To reduce image size I change node version node:12.18.4-alpine then it caches issues as I mentioned above.

When using alpine, you need to install build dependencies for some node modules to be able to be built natively. It should probably be documented
Note:
if just use the base as node:12 or any other version your image size will be more than 1GB some cases.

How to speed up Node re-builds by leveraging Docker multi-stage builds
if you are using alpine, you need to install build dependencies for some node module to be able to be built natively.

Example

FROM node:8.12-alpine
EXPOSE 8080
WORKDIR /app
COPY . .
#python
RUN apk add --no-cache --virtual .gyp \
        python \
        make \
        g++ \
    && npm install \
    && apk del .gyp
CMD ["npm", "start"]

I will suggest you for checking bcrypt $ bcryptjs npm docs.
node-gyp only works with stable/released versions of node. Since the bcrypt module uses node-gyp to build and install, you'll need a stable version of node to use bcrypt. If you do not, you'll likely see an error that starts with:

Alt Text

In the end, It resolves all issues like slow build &Python is not installed &, etc.

#My first stage, that is the Builder
FROM  node:12.18.4-buster AS build
#RUN apk add --update --no-cache \
#    python \
#    make \
#    g++
COPY . .
# If you have native dependencies, you'll need extra tools
RUN npm install
#RUN npm install
RUN npm run build
RUN npm prune --production
#CMD npm run start-prod
#EXPOSE 3001
## My Second stage, that creates an image for production
FROM node:12.18.4-alpine
WORKDIR /app
COPY --from=build ./dist ./dist
COPY --from=build ./node_modules ./node_modules
CMD npm run start-prod
EXPOSE 3001

It worked for me!
