# Produces an image that runs cloud-init under a debugger. To use, build and push
# to a registry with:
#
# docker buildx build -f Dockerfile.debug --load -t my-docker-tag:my-revision .
#
# and configure your deployment to use that image. Disable any liveness checks
# (when the debugger is paused, service readiness/liveness endpoints will not respond,
# and watchdogs will perceive the container as dead) and connect to the debugger listen:
#
# dlv connect container-hostname.example:2345
