container-entrypoint

A template for scripting container entrypoints with modular, drop-in shell scripts.

How It Works

container-entrypoint.sh sources every *.sh script in /container-entrypoint.d/ in order, then execs the container command. If the command is init-loop, it sleeps forever instead (useful for sidecar/init containers).

Entrypoint scripts are sourced, not executed as subshells, so they can modify the shell environment for subsequent scripts.

Usage

Use as a base image or copy the entrypoint into your own image:

FROM alpine:latest

COPY container-entrypoint.sh /container-entrypoint.sh
COPY container-entrypoint.d /container-entrypoint.d
RUN chmod 555 /container-entrypoint.sh

ENTRYPOINT [ "/container-entrypoint.sh" ]

Adding Custom Scripts

Drop additional *.sh scripts into /container-entrypoint.d/. They are sourced in filename order, so use numeric prefixes to control execution order (e.g. 20-custom-setup.sh).
