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
|
|
|
|
```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 file source
|
|
conf.Load(consulSource)
|
|
```
