micro/config/source/consul/README.md
magodo 606b1ff7cf prefix in consul api starts with no leading slash 
When `consul.StripPrefix(true)` is set, current impl. will pass the
specified prefix (or default prefix) when calling consul api.

However, `prefix` in consul api starts with no leading slash, so
the default prefix (`/micro/config`) doesn't actually work.

I avoid code changes (esp. the one in `util.go`) to eliminate
impact on users who already notice it.

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

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

// Create new config
conf := config.NewConfig()

// Load file source
conf.Load(consulSource)
