unknown option "-L3000:localhost:3000" while deploying Grafana

Question

I was following the single node file server tutorials on Google cloud platform where it told me to create an SSH tunnel, use the following gcloud command:

gcloud compute ssh --ssh-flag=-L3000:localhost:3000 --project=PROJECT --zone=ZONE INSTANCE_NAME

I enter the command on the gcloud sdk, and then I get this message.

unknown option "-L3000:localhost:3000"

Image of the message.

What did I do wrong? Any help will be appreciated. Thank you.

Answer 1

Try --ssh-flag="-L 3000:localhost:3000", PuTTY expects a space between the -L flag and the port definition.
