# Usage: initContainer <container_id> <software> [db_name]
#
# Creates /4server/data/<container_id>/config/container.env
#
# <container_id> : new codename (e.g. "banana")
# <software>     : n8n | ODOO_17 | ODOO_18 | ODOO_19
# [db_name]      : optional — postgres DB/user name to use.
#                  Defaults to <container_id>.
#                  Pass the OLD container_id here when migrating an existing container
#                  so the existing postgres database is reused.
#
# Examples:
#   New container:
#     initContainer banana ODOO_19
#
#   Migrating existing container (old container_id kept as DB name):
#     initContainer banana ODOO_19 005-003-91f3922c-8cc2-4950-aa57-808775c341ff
