env

README

env has higher precedence than file config and you can use under core to replace dot in env to replace file config

for example, to change config user

cred:
  db:
    user: admin
    pwd:

you only need to set env "cred_db_user" or "cred.db.user"

then you can use archaius to get it, file config will be overwrite by env

archaius.Get("cred.db.user")

go build main.go
./main
