Docker Alpine: unable to select packages: python (no such package) while building image for ARM-CodePudding

I have Node.js app that uses SQLite database. To use it on ARM architecture, I need to build sqlite3 binaries so I need some packages while building Docker image.

Here is my Dockerfile:

FROM node:14-alpine as builder

WORKDIR /app

COPY package*.json ./

RUN apk update \
    && apk --no-cache --virtual build-dependencies add python make g   \
    && npm install --production

COPY . .    

RUN mkdir -p ./public ./data \
    && cd ./client \
    && npm install --production \
    && npm run build \
    && cd .. \
    && mv ./client/build/* ./public \
    && rm -rf ./client \
    && apk del build-dependencies

FROM node:14-alpine

COPY --from=builder /app /app

WORKDIR /app

EXPOSE 5005

ENV NODE_ENV=production

CMD ["node", "server.js"]

I've been using it for 6 months and it was working fine but now it throws this error:

I tried to specific python version like so: ... add python3 make .... It passes this step but I'm getting this error while building sqlite3 binaries:

CodePudding user response：

We hit the same error and in our case explicitly targeting python3 seems to fix it. I asked on IRC, did not find out yet why python is not working anymore, but was told that python2 still provides /usr/bin/python. So maybe you actually need python2?

CodePudding user response：

RUN apk add --no-cache --virtual .gyp python3 make g
