The Argo CD UI displays icons for various Kubernetes resource types to help users quickly identify them. Argo CD includes a set of built-in icons for common resource types.

You can contribute additional icons for custom resource types by following these steps:

1. Ensure the license is compatible with Apache 2.0.
2. Add the icon file to the ui/src/assets/images/resources/<group>/icon.svg path in the Argo CD repository.
3. Modify the SVG to use the correct color, #8fa4b1.
4. Run make resourceiconsgen to update the generated typescript file that lists all available icons.
5. Create a pull request to the Argo CD repository with your changes.

<group> is the API group of the custom resource. For example, if you are adding an icon for a custom resource with the API group example.com, you would place the icon at ui/src/assets/images/resources/example.com/icon.svg.

If you want the same icon to apply to resources in multiple API groups with the same suffix, you can create a directory prefixed with an underscore. The underscore will be interpreted as a wildcard. For example, to apply the same icon to resources in the example.com and another.example.com API groups, you would place the icon at ui/src/assets/images/resources/_.example.com/icon.svg.
