So here is another solution in order not to use the internet, and it is super fast to load. No need to use the filesystem too.
Get your icon ready.
Go to
I can’t post links, so search for Guru Base64 and go there.
In the Datatype, use Local File (and upload the file) or Remote URL (and paste the url of the icon). I use SVG, not sure about other icon types, should work though.
in the Output Format, select “Data URI – data:content/type;base64”
Click “Encode image to Base64”
Copy the textbox inside Base64
Go to
/mnt/.ix-apps/app_configs/{container_name}
nano metadata.yaml
inside the metadata: section add
icon: ‘{The base64 you copied}’
BE CAREFUL TO HAVE THE RIGHT NUMBER OF TABS, the Base64 MUST be surrounded by single quotes ‘{base64here}’.
Go to the container, edit it and save, in your browser, CTRL + SHIFT + R to force refresh.
