the image with a string value, which is easy for humans to read and recognize.
If you don't pass a `--tag`, Docker will use `latest` as the default value.

Build your first Docker image.

```console
$ docker build --tag docker-gs-ping .
```

The build process will print some diagnostic messages as it goes through the build steps.
The following is just an example of what these messages may look like.

Your exact output will vary, but provided there aren't any errors, you should
see the word `FINISHED` in the first line of output. This means Docker has
successfully built your image named `docker-gs-ping`.

## View local images

To see the list of images you have on your local machine, you have two options.
One is to use the CLI and the other is to use [Docker
Desktop](/manuals/desktop/_index.md). Since you're currently working in the
terminal, take a look at listing images with the CLI.

To list images, run the `docker image ls`command (or the `docker images` shorthand):
