> Perform your add & remove operations in the same RUN command. Doing them separately creates two separate layers which inflates the image size.
>
> This creates two image layers - the first layer has all the added foo, including any intermediate artifacts. Then the second layer removes the intermediate artifacts, but that's saved as a diff against the previous layer:
>
> ```docker
> ```

RUN ./install-foo RUN ./cleanup-foo

````
>
> Instead, you need to do them in the same RUN command:
>
> ```docker
RUN ./insall-foo && ./cleanup-foo
````

> This creates a single layer which has only the foo artifacts you need.
>
> This why the [official Dockerfile best practices show](https://docs.docker.com/develop/develop-images/dockerfile_best-practices/#run) the apt cache being cleaned up in the same RUN command:
>
> ```docker
> ```

RUN apt-get update && apt-get install -y\
package-bar\
package-baz\
package-foo\
&& rm -rf /var/lib/apt/lists/\*

````

### Docker compose

Aka `compose.yaml` (or `docker-compose.yml` or `compose.yml`)

### Virtual Machine

If the host is not Linux or the image use on other OS use a virtual machine container
