You may also want to store your icons locally, bundled within Dashy so that there is no reliance on outside services. This can be done by putting the icons within Dashy’s ./public/item-icons/ directory. If you are using Docker, then the easiest option is to map a volume from your host system, for example: -v /local/image/directory:/app/public/item-icons/. To reference an icon stored locally, just specify it’s name and extension. For example, if my icon was stored in /app/public/item-icons/maltrail.png, then I would just set icon: maltrail.png.
You can also use sub-folders within the item-icons directory to keep things organized. You would then specify an icon with it’s folder name slash image name. For example: networking/monit.png
