# safeclaude-base — the shared base every project builds on. Keep this generic:
|
|
# project-specific packages and language versions go in each project's own
|
|
# .safeclaude/Dockerfile (which starts with `FROM safeclaude-base`), not here.
|
|
#
|
|
# This image runs as root so project Dockerfiles can install system packages
|
|
# freely. Don't worry — the launcher locks things down at run time (normal user,
|
|
# no special privileges), so nothing Claude does actually runs as root.
|
|
#
|
|
# Debian (slim) as the base: small, stable, and its apt packages behave
|
|
# predictably in a container — notably `chromium` is a real package here, unlike
|
|
# on Ubuntu where it's a snap stub that won't run in a container.

# We leave apt's package lists in place (no cleanup) so a project Dockerfile can
|
|
# install packages without re-fetching them — though it should still run its own
|

# `apt-get update` first, since this base image may be days or weeks old.
