More booted checks #2
Description
Currently, the boot label supports the CMD kind, which will run a command inside the container to determine whether it's up and running; and NONE. Like Docker's HEALTHCHECK, this is meant to be extended in the future.
FROM debian:jessie
# LABEL boot NONE
LABEL boot CMD /boot.sh
HEALTHCHECK CMD /health.sh
CMD ...Ideas for kinds
HTTP- issues a HTTP request against a given URL, 2xx = sucess, error otherwise (see also Support HTTP health checks moby/moby#25364)PORT- waits until a given port is open
Extension point
This switch statement is the correct place for implementing more checks.
