# Consul Source
The consul source reads config from consul key/values
## Consul Format
The consul source expects keys under the default prefix `/micro/config`
Values are expected to be json
```
// set database
consul kv put micro/config/database '{"address": "10.0.0.1", "port": 3306}'
// set cache
consul kv put micro/config/cache '{"address": "10.0.0.2", "port": 6379}'
```
Keys are split on `/` so access becomes
```
conf.Get("micro", "config", "database")
```
## New Source
Specify source with data
```go
consulSource := consul.NewSource(
// optionally specify consul address; default to localhost:8500
consul.WithAddress("10.0.0.10:8500"),
// optionally specify prefix; defaults to /micro/config
consul.WithPrefix("/my/prefix"),
// optionally strip the provided prefix from the keys, defaults to false
consul.StripPrefix(true),
)
```
## Load Source
Load the source into config
```go
// Create new config
conf := config.NewConfig()
// Load consul source
conf.Load(consulSource)
```

# Etcd Source
The etcd source reads config from etcd key/values
This source supports etcd version 3 and beyond.
## Etcd Format
The etcd source expects keys under the default prefix `/micro/config` (prefix can be changed)
Values are expected to be JSON
```
// set database
etcdctl put /micro/config/database '{"address": "10.0.0.1", "port": 3306}'
// set cache
etcdctl put /micro/config/cache '{"address": "10.0.0.2", "port": 6379}'
```
Keys are split on `/` so access becomes
```
conf.Get("micro", "config", "database")
```
## New Source
Specify source with data
```go
etcdSource := etcd.NewSource(
// optionally specify etcd address; default to localhost:8500
etcd.WithAddress("10.0.0.10:8500"),
// optionally specify prefix; defaults to /micro/config
etcd.WithPrefix("/my/prefix"),
// optionally strip the provided prefix from the keys, defaults to false
etcd.StripPrefix(true),
)
```
## Load Source
Load the source into config
```go
// Create new config
conf := config.NewConfig()
// Load file source
conf.Load(etcdSource)
```
