budibase/hosting/couchdb/Dockerfile

# Modified from https://github.com/apache/couchdb-docker/blob/main/3.2.1/Dockerfile
#
# Everything in this `base` image is adapted from the official `couchdb` image's
# Dockerfile. Only modifications related to upgrading from Debian bullseye to
# bookworm have been included. The `runner` image contains Budibase's
# customisations to the image, e.g. adding Clouseau.
