- kubeadm now works better when not connected to the Internet. In addition,  common kubeadm commands will now work without an available networking interface. ([#67397](https://github.com/kubernetes/kubernetes/pull/67397), [@neolit123](https://github.com/neolit123))

Sie würden also **mehrere Container** mit unterschiedlichen Dingen ausführen, wie einer Datenbank, einer Python-Anwendung, einem Webserver mit einer React-Frontend-Anwendung, und diese über ihr internes Netzwerk miteinander verbinden.

In alle Containerverwaltungssysteme (wie Docker oder Kubernetes) sind diese Netzwerkfunktionen integriert.

Beachten Sie, dass die Funktion die Exception-Instanz zurückgibt; sie wirft sie nicht. Das Werfen erfolgt im restlichen internen Code.

- Kubeadm: now sets the host `OS` environment variables when executing `crictl` during image pulls. This fixed a bug where `*PROXY` environment variables did not affect `crictl` internet connectivity.

### Types génériques avec des paramètres de types

Il existe certaines structures de données qui contiennent d'autres valeurs, comme `dict`, `list`, `set` et `tuple`. Et les valeurs internes peuvent elles aussi avoir leurs propres types.

Pour déclarer ces types et les types internes, on utilise le module standard de Python `typing`.

Il existe spécialement pour supporter ces annotations de types.

#### `List`

import java.util.Map;
import java.util.Objects;
import java.util.WeakHashMap;

/**
 * Represents a parsed phase identifier.
 */
public class PhaseId {
    /**
     * Interned {@link PhaseId} instances.
     */
    private static final Map<String, PhaseId> INSTANCES = new WeakHashMap<>();

    /**
     * The execution point of this {@link PhaseId}.
     */
