  - local config file;
  - environment vars;
  - default config file (contained in ``bigchaindb.__init__``).

-This means that if the default configuration contains an entry that is:
-
-```
-{...
-    "database": {"host": "localhost",
-                 "port": 28015}
-...}

-while your local file `local.json` contains:
-```
-{...
-    "database": {"host": "whatever"}

-and you run this command:
-```
-$ BIGCHAINDB_DATABASE_HOST=foobar BIGCHAINDB_DATABASE_PORT=42000 bigchaindb -c local.json show-config
