The script installs and exposes the database only; it now prints a generic MongoDB connection string (mongodb://user:pass@ip:27017/) instead of a LibreChat MONGO_URI with a hardcoded /LibreChat database. README 'Wiring LibreChat' section replaced with a generic 'Connecting a client' section. Application wiring is left to that app's own config or a separate script.

# install.sh - FerretDB: LXC creation, installation & update
|
|
# Usage:
|
|
# From Proxmox host : bash -c "$(curl -fsSL https://gitea.arnodo.fr/Damien/infra-scripts/raw/branch/main/ferretdb/install.sh)"
|
|
# From inside LXC : bash /root/install.sh (updates packages)
|
|
#
|
|
# Single entrypoint, three automatic modes:
|
|
# 1. Proxmox host, no existing container -> create Debian LXC + install FerretDB
|
|
# 2. Proxmox host, container already present -> update packages + upgrade FerretDB
|
|
# 3. Inside an LXC -> install if missing, otherwise update
|
|
#
|
|
# FerretDB v2 is a MongoDB wire-protocol proxy backed by PostgreSQL + the
|
|
# DocumentDB extension. The extension is a compiled C PostgreSQL extension and
|
|
# is only published as deb/rpm packages (no Alpine/musl build), so this stack
|
|
# runs on Debian — unlike the openbao/gitea-runner Alpine LXCs in this repo.
|
|
#
|
|
# The package install/upgrade logic lives in a single reusable function
|
|
# (install_or_upgrade_packages) shared by both the create and update paths.
|
|
