From 455f6dcb8c7355cd7a488bcad8474b3f61e4fbbd Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?J=C3=A9r=C3=B4me=20Warnier?= Date: Wed, 24 Jun 2026 17:59:40 +0200 Subject: [PATCH 1/6] docker: switch to a 2-stage build Use a builder stage to install opensips-cli from latest master, then copy only the installed library tree and script into the final image. This avoids shipping git and build artifacts in the published image. Also: use --no-cache-dir for pip, COPY instead of ADD, drop redundant USER root and PYTHONPATH, and make the base image configurable via --build-arg BASE_IMAGE=.
