I am trying to use "gcloud compute ssh" in wrapper script to enable access for Ansible when we are behind OS Login:

https://www.reddit.com/r/ansible/comments/e9ve5q/ansible_slow_as_a_hell_with_gcp_iap_any_way_to/

when I run more stressful:

for ((i=0; i<10; i+=1)) do for h in stage-agency-admin stage-am-batch-server stage-async stage-sabre-batch-server stage-sabre-rp stage-smart-agent-service stage-tp-batch-server; do (echo ok | gcloud compute ssh --tunnel-through-iap $h -- echo $h ok; echo $h: $?;)& done; done

where is extra warning and errors:

ERROR: gcloud crashed (OperationalError): disk I/O error

I run that in WSL.

My college froze Gnome on Linux with latest command.

I assume that local sqlite (or something like that) is in use and it forbids concurrent modifications.

I assume that gcloud MUST NOT be called in parallel.
