For anyone still facing this issue, I managed to fix it by adding the following to the top of the Dockerfile, just after FROM node:14-alpine:

ENV PYTHONUNBUFFERED=1
RUN apk add --update --no-cache python3 && ln -sf python3 /usr/bin/python
RUN python3 -m ensurepip
RUN pip3 install --no-cache --upgrade pip setuptools

(see here for context)

If the build process hangs on

=> [ 2/11] RUN apk add --update --no-cache python3 && ln -sf python3 /usr/bin/python
=> => # fetch https://dl-cdn.alpinelinux.org/alpine/v3.17/main/x86_64/APKINDEX.tar.gz

then try modifying the build command line to include --network host, i.e.:

docker build --network host -t snippet-box:latest .
