getty cannot start with image build by docker build about linuxkit HOT 2 CLOSED

Yeah, that is it. There are certain permissions.

• linuxkit build just builds a runnable OS image that you can then boot up via linuxkit run or an AWS or VMware or bare metal, etc.
• docker build builds the image, as you saw
• linuxkit pkg build pretty much runs a docker build, but it does so in an opinionated fashion. It sets certain parameters including required runtime permissions on the image (saved in the image's config), that linuxkit build knows to look for as defaults.

Essentially, linuxkit pkg build is "run a docker build using a bunch of settings from a config file build.yaml". You can see the additional information in getty's build.yml. Look at all of the stuff in the config key of that yaml file.

You can override any of those, or you can set them explicitly in the linuxkit yaml file, see the package specification in this doc.
