docker - What process signal does pod receive when executing `kubectl rolling-update`? -


i making graceful shutdown feature using go lang when kebernetes doing rolling-update on google container engine. know process signal sent running pods when kubectl rolling-update starts?

i've listened os.kill, os.interrupt, syscall.sigterm, syscall.sigkill, syscall.sigstop signals handled, none of signals raised while kubectl rolling-update.

i appreciate answers.

i got solution! used shell script file entrypoint , executed go binary in script file. process id of executed go binary not 1.(shell script process's id 1 instead) , docker sent sigterm pid 1(which not propagated it's child processes). so, had change entrypoint direct executing go binary, , got sigterm in go code now. refer link

(side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now
