# State with Postgres Store
|
|
|
|
Use the Postgres store for persistent key/value state.
|
|
|
|
## In code
|
|
|
|
```go
|
|
package main
|
|
|
|
import (
|
|
"log"
|
|
"go-micro.dev/v6"
|
|
"go-micro.dev/v6/store"
|
|
postgres "go-micro.dev/v6/store/postgres"
|
|
)
|
|
|
|
func main() {
|
|
st := postgres.NewStore()
|
|
svc := micro.NewService("postgres-store", micro.Store(st))
|
|
svc.Init()
|
|
|
|
_ = store.Write(&store.Record{Key: "foo", Value: []byte("bar")})
|
|
recs, _ := store.Read("foo")
|
|
log.Println("value:", string(recs[0].Value))
|
|
|
|
svc.Run()
|
|
}
|
|
```
|
|
|
|
## Via environment
|
|
|
|
Run your service with env vars set:
|
|
|
|
```bash
|
|
MICRO_STORE=postgres \
|
|
MICRO_STORE_ADDRESS=postgres://user:pass@127.0.0.1:5432/postgres \
|
|
MICRO_STORE_DATABASE=micro \
|
|
MICRO_STORE_TABLE=micro \
|
|
go run main.go
|
|
```
