move instance

gcloud compute instances move <instance_wanna_move> --destination-zone=us-central1-a --zone=us-central1-c

ssh & scp

#--verbosity=debug is great for debugging, showing the SSH command
# the following is a real word example for running a bastion server that talks to a GKE cluster (master authorized network)
gcloud compute ssh --verbosity=debug <instance_name> --command "kubectl get nodes"

ssh port forwarding for elasticsearch

gcloud compute --project "foo" ssh --zone "us-central1-c" "elasticsearch-1"  --ssh-flag="-L localhost:9200:localhost:9200"

The 2nd localhost is relative to elasticsearch-1`

ssh reverse port forwarding

for example, how to connect to home server's flask server (tcp port 5000) for a demo or a local game server in development

GOOGLE_CLOUD_PROJECT=$(gcloud config get-value project)
gcloud compute --project "${GOOGLE_CLOUD_PROJECT}" ssh --zone "us-west1-c" --ssh-flag="-v -N -R :5000:localhost:5000" "google_cloud_bastion_server"
