From 4aa021a5115b0bee6995b5bfba2a29563f0cd02f Mon Sep 17 00:00:00 2001 From: openhands Date: Thu, 5 Mar 2026 20:05:42 +0000 Subject: [PATCH] feat: switch default base image to nikolaik slim variant Switch the default base container image from nikolaik/python-nodejs:python3.12-nodejs22 to nikolaik/python-nodejs:python3.12-nodejs22-slim. Benefits: - ~500 MB smaller image size on disk (16% reduction) - ~62% smaller compressed size for faster downloads - Faster Kubernetes node autoscaling due to reduced pull times - Full functional parity with the non-slim variant The slim variant is based on Debian slim, which removes non-essential packages while maintaining all functionality needed for OpenHands runtime.
