To set custom logo and styles, go to master server with root permissions.
Use command kdcustomize to set path to files. For example:
--logo and --styles - path to files for KuberDock user and administrations panels;
--login-logo and --login-styles - path to files for login page of KuberDock.
Size of logo and login-logo are different and must be equal to 162x48 and 227x67 pixels accordingly. If an image of different size is specified, an error will be raised.
It's advisable to clear a browser cache after updating logos and styles.
Note that currently resetting to original logos and removing custom styles are not provided.
