# We push the image to hub twice, once with the full kernel version of
|
|
# "linuxkit/kernel:<kernel version>.<major version>.<minor version>-<n>",
|
|
# where "<n>" is a monotonically increasing config number, and as
|
|
# "linuxkit/kernel:<kernel version>.<major version>.x". This version
|
|
# number is stored in IMAGE_VERSION.
|
|
#
|
|
# We expect most users to us the "<kernel version>.<major version>.x"
|
|
# variant as this simply is the latest version of a given major kernel
|
|
# version. This version number is stored in IMAGE_MAJOR_VERSION.
|
|
#
|
|
# For IMAGE_VERSION, the "<n>" must be increased whenever
|
|
# the kernel config or the patches change. We don't expect this to
|
|
# happen very often as the minor version number gets update quite
|
|
# frequently.
|
|
#
|
|
# IMAGE_VERSION is used to determine if a new image should be pushed to hub.
