# 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)
|
|
```
