# ownCloud Infinite Scale: Runtime
|
|
|
|
Pman is a slim utility library for supervising long-running processes. It can be [embedded](https://github.com/owncloud/OCIS/blob/ea2a2b328e7261ed72e65adf48359c0a44e14b40/OCIS/pkg/runtime/runtime.go#L84) or used as a cli command.
|
|
|
|
When used as a CLI command it relays actions to a running runtime.
|
|
|
|
## Usage
|
|
|
|
Start a runtime
|
|
|
|
```go
|
|
package main
|
|
import "github.com/owncloud/ocis/ocis/pkg/runtime/service"
|
|
|
|
func main() {
|
|
service.Start()
|
|
}
|
|
```
|
|
|
|
|
|
Start sending messages
|
|
|
|
|
|
## Example
|
|
|
|
```go
|
|
package main
|
|
|
|
import (
|
|
"fmt"
|
|
"github.com/owncloud/ocis/ocis/pkg/runtime/process"
|
|
"github.com/owncloud/ocis/ocis/pkg/runtime/service"
|
|
"github.com/rs/zerolog/log"
|
|
"os"
|
|
"os/signal"
|
|
"syscall"
|
|
"time"
|
|
)
|
|
|
|
func main() {
|
|
s := service.NewService()
|
|
var c = make(chan os.Signal, 1)
|
|
var o int
|
|
|
|
signal.Notify(c, syscall.SIGINT, syscall.SIGTERM)
|
|
if err := s.Start(process.NewProcEntry("ocs", nil, "ocs"), &o); err != nil {
|
|
os.Exit(1)
|
|
}
|
|
|
|
time.AfterFunc(3*time.Second, func() {
|
|
var acc = "ocs"
|
|
fmt.Printf(fmt.Sprintf("shutting down service: %s", acc))
|
|
if err := s.Controller.Kill(&acc); err != nil {
|
|
log.Fatal()
|
|
}
|
|
os.Exit(0)
|
|
})
|
|
|
|
for {
|
|
select {
|
|
case <-c:
|
|
return
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
Run the example above with `RUNTIME_KEEP_ALIVE=true` and with no `RUNTIME_KEEP_ALIVE` set to see its behavior. It requires an [oCIS binary](https://github.com/owncloud/ocis/releases) present in your `$PATH` for it to work.
