# v1.84.0 is the fix line for CVE-2026-35029 (auth bypass on
# /config/update, fixed 1.83.0) and CVE-2026-59822 (MCP session auth
# bypass, fixed 1.84.0, CISA KEV catalog). Pin the exact tag — do NOT
# use a floating tag like main-v1.74.0-stable, which silently moved.

# LiteLLM's official image runs as root. Cloudron's sandboxing (read-only
# rootfs, AppArmor, dropped capabilities) still applies to root inside the
# container, so we keep root to match the base image and avoid /app/data
# volume-ownership issues.

# Create the data directory (Cloudron mounts the localstorage volume here)
RUN mkdir -p /app/data /app/code

# Create a startup script that configures LiteLLM with Cloudron addons
COPY start.sh /app/code/start.sh
RUN chmod +x /app/code/start.sh

# Default config — will be overridden by Cloudron env vars at runtime
COPY config.yaml /app/data/config.yaml
# A second copy inside the image: start.sh syncs it over the persistent
# /app/data volume at boot, so config changes in the repo actually deploy.
COPY config.yaml /app/code/config.yaml

# Append the co-op credit-pack hint to LiteLLM's hardcoded budget-exceeded
# messages. Done at BUILD time — the runtime rootfs is read-only under
# Cloudron, so a boot-time patch would crash the startup script (it did,
# 2026-10-06). patch_budget_message.py is non-fatal: it exits 0 even when the
# file/message can't be found, so a future LiteLLM version bump can't take the
# gateway down.

# Image-cost tracking: keep image-generation pricing on the shared cost-map
# key so successful image generations appear in SpendLogs (upstream bug
# BerriAI/litellm#10023/#12471 — closed not-planned). Non-fatal at build.

# Audio per-request pricing: Tinfoil bills voxtral-tts and whisper per request,
# which LiteLLM cannot express on the audio paths, so those two were billed at
# $0. The patch makes the cost calculator honour a declared
# input_cost_per_request. Check for the "[coop-patch] applied" line in the build
# log after upgrading LiteLLM: the script is non-fatal and warns instead.

# The audio cost paths read pricing from the SHARED cost-map key, which the
# router strips per-deployment pricing from — so the lookup raised, the spend
# write was skipped, and audio produced no SpendLogs row at all. This re-adds the
# pricing (and input_cost_per_request) for the audio modes. Same mechanism as
# patch_image_cost.py above.

# SECURITY (2026-10-27, member-disclosure finding 4): LiteLLM forwards every
# provider response header to callers as `llm_provider-*`, which leaked the
# co-op's remaining provider balance (x-credits-remaining) to any member API key.
# Verify the "[coop-patch] applied: provider response headers" line in the build
# output on every version bump — the patch is non-fatal by design.

# Member access to config-declared pass-through routes: LiteLLM gates auth=true
# pass-through endpoints behind `allowed_passthrough_routes`, an Enterprise-only
# field that cannot be set on this community-edition proxy. This patch lets any
# authenticated key call routes the operator lists in
# general_settings.coop_passthrough_open_to_keys (unauthenticated access is
# unaffected — still rejected). Non-fatal; check the "[coop-patch] applied" line
# in the build log on every LiteLLM upgrade.

# Override the base image's ENTRYPOINT (which is `litellm`) so our

# No CORS patch needed since v1.84.0: upstream replaced the hardcoded
# `origins = ["*"]` with a native LITELLM_CORS_ORIGINS env var (start.sh
# exports it). The old sed patch targeted a v1.74.0 file layout that no
# longer exists — the v1.84.0 rebuild self-skipped it correctly.
