Need method of providing git commit information about cri-dockerd HOT 3 CLOSED

As long as the build doesn't fail, it's OK to leave it empty.

	// PreRelease is set during the build
	PreRelease = ""
	// GitCommit is set during the build
	GitCommit = "HEAD"
	// BuildTime is set during the build
	BuildTime = "<unknown>"

It looks weird, but 70's seems to be "industry standard".

Like podman:

    "GitCommit": "",
    "BuiltTime": "Thu Jan  1 01:00:00 1970",
    "Built": 0,

The current build works OK when git is missing, but fails (wrong repo!) when the build files are using git themselves.

So in order to not have the build pick up the version of the OS or whatever, it is more explicit to provide the information.

from cri-dockerd.

So these values are recorded, and provided:

REVISION=$(git log -1 --pretty=%H)
SOURCE_DATE_EPOCH=$(git log -1 --pretty=%ct)

To replace the default "HEAD" and "<unknown>".
eb0c48ef49856f7d098ec005ddebcae197e08e49
1641267182

from cri-dockerd.

REVISION, SOURCE_DATE_EPOCH, and VERSION can now be set as environment variables or build-time options to make.

There's a --buildinfo flag to cri-dockerd which will show what they were set to.
