# Script for setting up telepresence to run the KServe controller
|
|
# locally, fully connected to the cluster (it works also for the
|
|
# incoming direction when used as a webhook)
|
|
#
|
|
# Usage:
|
|
# # Install everything. This command is idempotent and can
|
|
# # be called multiple times
|
|
# ./telepresence-setup.sh
|
|
#
|
|
# # Remove everything from telepresence
|
|
# ./telepresence-setup.sh uninstall
|
|
