# crypt/config
## Usage
### Get configuration from a backend
```
package main
import (
"fmt"
"log"
"os"
"github.com/xordataexchange/crypt/config"
)
var (
key = "/app/config"
secretKeyring = ".secring.gpg"
)
func main() {
kr, err := os.Open(secretKeyring)
if err != nil {
log.Fatal(err)
}
defer kr.Close()
machines := []string{"http://127.0.0.1:4001"}
cm, err := config.NewEtcdConfigManager(machines, kr)
if err != nil {
log.Fatal(err)
}
value, err := cm.Get(key)
if err != nil {
log.Fatal(err)
}
fmt.Printf("%s\n", value)
}
```
### Monitor backend for configuration changes
```
package main
import (
"fmt"
"log"
"os"
"github.com/xordataexchange/crypt/config"
)
var (
key = "/app/config"
secretKeyring = ".secring.gpg"
)
func main() {
kr, err := os.Open(secretKeyring)
if err != nil {
log.Fatal(err)
}
defer kr.Close()
machines := []string{"http://127.0.0.1:4001"}
cm, err := config.NewEtcdConfigManager(machines, kr)
if err != nil {
log.Fatal(err)
}
stop := make(chan bool, 0)
resp := cm.Watch(key, stop)
if err != nil {
log.Fatal(err)
}
for {
select {
case r := <-resp:
if r.Error != nil {
fmt.Println(r.Error.Error())
}
fmt.Printf("%s\n", r.Value)
}
}
}
```
