$ docker run -dit --name alpine1 --network alpine-net alpine ash

    $ docker run -dit --name alpine2 --network alpine-net alpine ash

    $ docker run -dit --name alpine3 alpine ash

    $ docker run -dit --name alpine4 --network alpine-net alpine ash

    $ docker network connect bridge alpine4
    ```

    Verify that all containers are running:

    ```console
    $ docker container ls

    CONTAINER ID        IMAGE               COMMAND             CREATED              STATUS              PORTS               NAMES

    ```

4.  Inspect the `bridge` network and the `alpine-net` network again:

    ```console
    $ docker network inspect bridge

    Containers `alpine3` and `alpine4` are connected to the `bridge` network.

    ```console
    $ docker network inspect alpine-net
