1. A method, comprising operations of:
creating an image definition file;
using the image definition file to create an image that has a full operating system and is to be deployed to an edge device;
copying an agent into the image, wherein only the agent residing on the edge device is able to make modification to the edge device;
stripping all user passwords from the image so that no user can log into the edge device after all user passwords are stripped from the image; and
removing any unnecessary packages, which do not have any dependency relations with other packages within the image, from the image by evaluating a package dependency tree,
wherein after the stripping and the removing, the image becomes an immutable image, which is configured for continuous deployment to the edge device.
