Features

• Multi-platform alpine based and distribution images
• Artifacts provided on releases page

Usage

This repository provides two images. The first one is built on top of alpine so, you can use it as a base image for your own images:

FROM crazymax/alpine-s6
RUN apk add --no-cache nginx
RUN echo "daemon off;" >> /etc/nginx/nginx.conf
CMD ["/usr/sbin/nginx"]

Note

ENTRYPOINT ["/init"] is already defined in the base image so no need to add this command.

The second one is a distribution image. This is a multi-platform scratch image that only contains all the scripts and binaries needed to run s6-overlay. This way you can use any base image and use the COPY --from command to copy the assets inside your image:

FROM ubuntu
COPY --from=crazymax/alpine-s6-dist / /
RUN apt-get update && apt-get install -y nginx
RUN echo "daemon off;" >> /etc/nginx/nginx.conf
CMD ["/usr/sbin/nginx"]
ENTRYPOINT ["/init"]
