When the **container** is started and running (started from a **container image**) it could create or change files, environment variables, etc. Those changes will exist only in that container, but would not persist in the underlying container image (would not be saved to disk).

A container image is comparable to the **program** file and contents, e.g. `python` and some file `main.py`.

## Was ist ein Container?

Container (hauptsächlich Linux-Container) sind eine sehr **leichtgewichtige** Möglichkeit, Anwendungen einschließlich aller ihrer Abhängigkeiten und erforderlichen Dateien zu verpacken und sie gleichzeitig von anderen Containern (anderen Anwendungen oder Komponenten) im selben System isoliert zu halten.

  * When live upgrading Kubelet to 1.2 without draining the pods running on the node,
the containers will be restarted by Kubelet (see details in [#23104](https://github.com/kubernetes/kubernetes/issues/23104)).

#### Docker Known Issues

##### 1.9.1

  * Listing containers can be slow at times which will affect kubelet performance.

/// tip

Don't worry if some of these items about **containers**, Docker, or Kubernetes don't make a lot of sense yet.
