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)
