# Docker Images

When creating your "shell" (non-Nextflow) workflow, we will provide a default Docker image URI, which uses Ubuntu. If you wish to use an alternative Docker image, you may provide the URI for the image.

> [!WARNING]
>
> Docker image URIs must be publicly accessible. If you require a private image, reach out to our team.

> [!NOTE]
>
> For Nextflow workflows, instead of an image, you can choose from our pre-installed Nextflow versions.
