You would probably want to have the thing in charge of restarting your application as an **external component**, because by that point, the same application with Uvicorn and Python already crashed, so there's nothing in the same code of the same app that could do anything about it.

### Example Tools to Restart Automatically

* Bump to container-vm-v20160321 ([#23313](https://github.com/kubernetes/kubernetes/pull/23313), [@zmerlynn](https://github.com/zmerlynn))
* Remove the restart-kube-proxy and restart-apiserver functions ([#23180](https://github.com/kubernetes/kubernetes/pull/23180), [@roberthbailey](https://github.com/roberthbailey))

  public void testPadStart_noPadding() {
    assertSame("", Strings.padStart("", 0, '-'));
    assertSame("x", Strings.padStart("x", 0, '-'));
    assertSame("x", Strings.padStart("x", 1, '-'));
    assertSame("xx", Strings.padStart("xx", 0, '-'));
    assertSame("xx", Strings.padStart("xx", 2, '-'));
  }

  public void testPadStart_somePadding() {
    assertEquals("-", Strings.padStart("", 1, '-'));
    assertEquals("--", Strings.padStart("", 2, '-'));

## Running on Startup and Restarts

There is normally another tool in charge of **starting and running** your container.

It could be **Docker** directly, **Docker Compose**, **Kubernetes**, a **cloud service**, etc.

In most (or all) cases, there's a simple option to enable running the container on startup and enabling restarts on failures. For example, in Docker, it's the command line option `--restart`.

  public void testPadStart_noPadding() {
    assertSame("", Strings.padStart("", 0, '-'));
    assertSame("x", Strings.padStart("x", 0, '-'));
    assertSame("x", Strings.padStart("x", 1, '-'));
    assertSame("xx", Strings.padStart("xx", 0, '-'));
    assertSame("xx", Strings.padStart("xx", 2, '-'));
  }

  public void testPadStart_somePadding() {
    assertEquals("-", Strings.padStart("", 1, '-'));
    assertEquals("--", Strings.padStart("", 2, '-'));

Once the config changes are applied, proceed to restart **Hadoop** services.

### **3.2 Configure Spark2**

Navigate to **Services** -> **Spark2** -> **CONFIGS** as shown below

	exit_1
fi

sleep 10

./mc idp ldap policy entities minio1
./mc idp ldap policy entities minio2
./mc idp ldap policy entities minio3

./mc admin service restart minio1
./mc admin service restart minio2
./mc admin service restart minio3

sleep 10

./mc idp ldap policy entities minio1
./mc idp ldap policy entities minio2
./mc idp ldap policy entities minio3

## Reference

### Design details

Broadly, `istio-cni` accomplishes ambient redirection by instructing ztunnel to set up sockets within the application pod network namespace, where:

access to port 9000

```sh
iptables -A INPUT -p tcp --dport 9000 -j ACCEPT
service iptables restart
```

Below command enables all incoming traffic to ports ranging from 9000 to 9010.

```sh
iptables -A INPUT -p tcp --dport 9000:9010 -j ACCEPT
service iptables restart
```

## Test MinIO Connectivity

### Test using MinIO Console

	globalObjLayerMutex.Lock()
	globalObjectAPI = objLayer
	globalObjLayerMutex.Unlock()
	return objLayer, erasureDirs, nil
}

// cmdType - Represents different service subcomands like status, stop
// and restart.
type cmdType int

const (
	restartCmd cmdType = iota
	stopCmd
)

// toServiceSignal - Helper function that translates a given cmdType
// value to its corresponding serviceSignal value.
