I think the problem with Kingpin was easily overriding, based on flag/file/env etc. See this issue alecthomas/kingpin#208, however it looks like something has been implemented to try and make this better alecthomas/kingpin#209, so that could be worth a look. Although it's only on v3-unstable
branch
from vault-creds.
Yeah, this seems like a reasonable thing to do, might look at switching to https://github.com/spf13/viper so that we can easily switch between flags, env and config file
from vault-creds.
I guess you don't need to switch to any other packet since you are already using kingpin. So you can easily add Env Vars:
vaultAddr = kingpin.Flag("vault-addr", "Vault address, e.g. https://vault:8200").Envar("VAULT_ADDR").String()
https://godoc.org/github.com/alecthomas/kingpin#FlagClause.Envar
from vault-creds.
true, I'm just thinking ahead as people might want a config file in the future
from vault-creds.
It looks like kingpin also has an option to read args from the config file:

from vault-creds.
