kubernetes - Does ReadWriteOnce access mode allow for auto scaling of associated pods? -


i have setup deployment (dep1) in k8s , there's persistent volume associated with access mode readwriteonce. have horizontalpodautoscale resource dep1 auto-scales deployment if cpu consumption above threshold. happen if deployments deployed across multiple nodes? auto-scaling work? in general, there concern regarding autoscaling when using pvs in readwriteonce mode?

i didn't try myself yet guess depends on type of volume work with. if work ebs pv, mounts across nodes @ same time aren't possible , pods fail if scheduled on different nodes. if use nfs type of volume on other hand, mounts on multiple nodes possible.

that being said, think have overthink access mode policy. readwriteonce per definition allows mount single node. think in scenario need change readwritemany.

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (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
