Wrappers for working with Craton: setting up dev servers, getting env vars, and using the REST API. Simply source, and use like so:$ craton-get v1/hosts. Etc.

craton-wrapper-functions.sh

# Example usage. Note that we simply pass through httpie conventions,
# such as nested JSON with :=
# (https://github.com/jkbrzt/httpie#non-string-json-fields)
#
# $ craton-post v1/regions name=HKG
# $ craton-get v1/hosts
# $ craton-put v1/hosts/3 device_type=container
# $ craton-put v1/hosts/3/variables foo=47 bar:='["a", "b", "c"]'
# $ craton-delete v1/hosts/4
#
# Additional commands provided to manage with respect to environment
# variables, docker startup, etc.

# NOTE assumes the installation of httpie so that the http command is available!
