balena build help missing -f flag

[srlowe]

balena build help mentions that an alternative dockerfile can be specified with the -f flag, but there is no alias defined for --dockerfile.

@pdcastro This appears to be defined in utils/compose.coffee appendOptions. I'll check if this was omitted for a reason (perhaps collides somewhere that uses appendOptions). Do you know of any reason this is not defined?

Do you know of any reason this is not defined?

@srlowe, actually I do! In a CLI check-in about a year ago, :-) I remember proposing the -f option to match docker build, but then someone else pointed out that docker-compose also uses -f to select an alternative docker-compose.yml file, and we would like the CLI push/build/deploy commands to be able to specify an alternative docker-compose.yml as well (pending issue #1142), and they could not both be -f. I had suggested having different single-char options, but somewhat to my surprise everybody else (Shaun, Cameron, Hedley, Akis) thought it was preferable not to have any single-character option at all, having only the --dockerfile long option name. I must have dropped the single-character option from the code but I guess I forgot to update the help output to match it. So the action to be taken would be to edit the help text to remove any reference to a -f option, unless you wanted to reopen the discussion with the product team. :-)

@pdcastro Ah thanks! I'll update the help.
