Installation

# Modelplane prerequisites. Apply once after installing Crossplane.
#
# These resources grant Crossplane and provider-helm the permissions
# needed to compose Gateway API, MetalLB, and Service/EndpointSlice
# routing resources. They cannot be self-composed because Crossplane
# needs the permissions before it can compose anything.

# Stop provider-kubernetes copying Secret data into Object status.
#
# It writes an observed object's whole manifest to status.atProvider.manifest,
# so for an Object whose manifest is a Secret, that Secret's data is readable by
# anyone who can get objects, which is a wider audience than can get secrets.
# Modelplane composes Secrets holding caller API keys and serving certificate
# private keys, so this redacts them.
#
# Redaction applies to a copy used only for status. Drift detection still reads
# the unredacted object, so this doesn't cause an Object to be perpetually out
# of date.
