Alpine-based Ruby Docker image with build-base installed.
e.g., You can replace
FROM ruby:3.3.1-alpine
...
RUN apk add --no-cache build-base && \
bundle install --no-cache && \
...
apk del --purge -r build-base
with
FROM kjuly/ruby-alpine-build-base:latest
...
RUN bundle install --no-cache && \
...
apk del --purge -r build-base
to save time on pkg build-base
installation during your Docker image testing, especially when your local network is not good enough.
