Subject: [PATCH 2/2] kata-shim: fix kata-shim process wait long time
|
|
to exit problem
|
|
|
|
reason: If containerd-shim process is killed and call kata-runtime delete -f command
|
|
to delete container, it will wait 10s for kata-shim process exit in the waitForShim
|
|
function, however 10s wait time is too long in the case of containerd-shim and containerd
|
|
process is killed.So when containerd-shim process is killed, kata-shim process will
|
|
receive a SIGHUP signal, we can handle this signal as exit signal which makes kata-shim
|
|
process exit.
