# Create a checkpoint of a gvisor sandbox. It is best to make the
|
|
# checkpoint in as close to the same circumstances as it will be used,
|
|
# because of some nuances around file descriptor ordering and
|
|
# mapping. So we create the checkpoint in a roundabout way, by opening
|
|
# node and creating an NSandbox, with appropriate flags set.
|
|
#
|
|
# Watch out if you feel tempted to simplify this, I initially had a
|
|
# much simpler solution that worked fine in docker, but on aws
|
|
# would result in a runsc panic related to file descriptor
|
|
# ordering/mapping.
|
|
#
|
|
# Note for mac users: the checkpoint will be made in the docker
|
|
# container running runsc.
