# Build stage to retrieve and build the frontend. Will pull in the frontend from
# the project root `frontend` folder. This stage hardcodes the build process for
# the built-in frontend. If you have a custom frontend with a different build
# process (although this one may work for you, as it's pretty standard), you'll
# need to create a new Dockerfile basing it off this one.

# We cannot compile our go program with C support, otherwise results in a "not
# found" error, when running the binary. This also disables DDT change watching
# and possibly other (future) features. However it is not expected that the former
# feature is of any use in secenarios we imagine the docker
# container is being run. Alternatively the tutorial at
# http://kefblog.com/2017-07-04/Golang-ang-docker can be used to enable CGO
# support.

# Force make to re-generate the to-be-embedded assets file. After a fresh

# entirely new files, especially when a custom frontend is used.
