Managed VM Deployment hangs on "Copying certificates for secure access..."

Question

I'm running the following command to deploy my Managed VMs app (on Windows 10):

gcloud preview app deploy app.yaml --project=<PROJECT> --promote

The deployment starts bug hangs on the following line:

Copying certificates for secure access. You may be prompted to create an SSH keypair.

And after some time I get the error:

ERROR: (gcloud.preview.app.deploy) Unable to copy certificates.

I've already:

• Made sure that there are SSH keys in ~\.ssh\google_compute_engine
• Tried to run with --quiet - same results
• Renamed ssh-term.exe to ssh.exe - same results
• Run the command as an administrator.
• Run the command with --verbosity debug, which prints the following line multiple times: DEBUG: File [f] does not exist locally.

Any help will be much appreciated!

Answer 1

Found the cause! It was the project's firewall that blocked SSH by default. Fixed that and it worked.

Answer 2

Glad you fixed it, I had the same problem and will use your fix. I did happen accros a work around. By using the Container Build API to perform the build.

enter the command

gcloud config set app/use_cloud_build true

Before you

gcloud preview app deploy
