Ansible GCP Zone

[Adam Barnett]

Hi, 

We are using GCP with ansible which has been working great up now, we are setting all the flags in ~/.ansible.cfg for ssh 

i.e 

ssh_args = -t -i ~/.ssh/google_compute_engine -o CheckHostIP=no -o ControlMaster=auto -o ControlPersist=600s -o IdentitiesOnly=yes -o UserKnownHostsFile=~/.ssh/google_compute_known_hosts -o ProxyCommand="/usr/bin/python3 -S /usr/lib64/google-cloud-sdk/lib/gcloud.py beta compute start-iap-tunnel %h %p --listen-on-stdin --project=studio-00056 --zone=europe-west1-b --verbosity=warning" -o ProxyUseFdpass=no

This has been fine, till we now have to use another zone, meaning that i need to switch the args 

I tired replacing the ssh_executable with my own wrapper

#!/bin/bash
set -x


host="${@: -2: 1}"
cmd="${@: -1: 1}"

# ControlMaster=auto & ControlPath=... speedup Ansible execution 2 times.
socket="/tmp/ansible-ssh-${host}-22-iap"

zone=$(gcloud compute instances list --filter="name:${host}" --format='value(zone)')
gcloud_args="
--tunnel-through-iap
--zone=$zone
--quiet
--no-user-output-enabled
--
-C
-o PreferredAuthentications=publickey
-o KbdInteractiveAuthentication=no
-o PasswordAuthentication=no
-o ConnectTimeout=20
-i ~/.ssh/google_compute_engine
-o CheckHostIP=no
-o ControlMaster=auto
-o ControlPersist=600s
-o IdentitiesOnly=yes
-o ProxyUseFdpass=no
"
        exec gcloud compute ssh "$host" $gcloud_args  "$cmd"

but this is is super slow as it does one ssh connection for each part of the playbook, a normal playbook before would take 33 seconds now it take 590 second

Any suggestion?

Thanks
Adam
