# This builds the supported LinuxKit kernels. Kernels are wrapped up
|
|
# in a scratch container, which contains the bzImage, a tar
|
|
# ball with modules, the kernel sources, and in some case, the perf binary.
|
|
#
|
|
# Each kernel is pushed to hub twice:
|
|
# - linuxkit/kernel:<kernel>.<major>.<minor>-<hash>
|
|
# - linuxkit/kernel:<kernel>.<major>.<minor>
|
|
# The <hash> is the git tree hash of the current directory. The build
|
|
# will only rebuild the kernel image if the git tree hash changed.
|
|
#
|
|
# For some kernels we also build a separate package containing the perf utility
|
|
# which is specific to a given kernel. perf packages are tagged the same way
|
|
# kernel packages.
