configo's Issues

Use MapStructure in place of double JSON decoding

See https://github.com/mitchellh/mapstructure

This will also provide some nice ways of handling configuration errors

Skip missed etcd keys

We are using etcd for storing configuration parameters for different services and usually, in service files, we have lines like that

-e CONFIGO_SOURCE_30='{\"type\": \"etcd\", \"endpoints\": [\"http://${COREOS_PRIVATE_IPV4}:2379\"], \"prefix\": \"applications/worker-defaults/\"}' \
-e CONFIGO_SOURCE_40='{\"type\": \"etcd\", \"endpoints\": [\"http://${COREOS_PRIVATE_IPV4}:2379\"], \"prefix\": \"applications/worker/%i\"}' \

So most of these workers are fine with default parameters and we don't need to customize these settings, but we have to create empty dir /application/worker/something and that is really annoying.

Is it possible to add one more configuration parameter like 'skipOnMissed' or something like that for nicer configuration?

Certificate authentication for https source type

We need auth by cert support. Like this auth https://user:[email protected]/config/app/profile/..., but by SSL certificate

Using SSL guarded resource example:

curl -k --key client.key --cert my_client_key.crt --url "https://myhost.com/config/app/profile"

Can ssl auth be implemented?

unable to get values from vault.

Could you please help me resolve this issue?

Dump json/yaml instead of making environment variables.

Great tool!
IMHO just one option missed: create son/xml file as result of parsing config sources. I have a lot of legacy code that required json/yaml config files. it would be great to dump json/yaml to disk.
