App Engine Deploy: credentials file not writable. ... Opening in read-only mode. ... Any refreshed credentials will only be valid for this run

I recently upgraded my cloud SDK, and now I can no longer deploy to app engine flexible. I deploy my app with the following command:

C:\Program Files (x86)\Google\Cloud SDK\google-cloud-sdk\bin\gcloud.cmd preview app deploy --promote vm.yaml

I am getting get the following output and crash (abridged):

WARNING: Could not acquire lock C:\Users\Michael\AppData\Roaming\gcloud\credentials.lock in 0 seconds
WARNING: The credentials file (C:\Users\Michael\AppData\Roaming\gcloud\credentials) is not writable. Opening in read-only mode. Any refreshed credentials will only be valid for this run.

The better way is to solve this error is to reinstall after deleting the root directory where lock file is.

I've also ran into this issue as well. How it happened --> I ran gcloud app deploy command, but later realised that the deployment took much longer to finish (perhaps hanging), then I killed the batch process i.e. CTRL +C. When I reissued the command thats when I got into this issue. So the SOLUTION, do what's already said above i.e. go and delete the credentials.lock file (in my case it found in C:\Users\Sam\AppData\Roaming\gcloud directory)

I recently had the same issue. Go to the directory shown in the error message. You'd find two credientials files. Delete the one with the LOCK extension( it would be the empty one). Then redeploy your project. Worked perfectly for me.

This is a bug with the Google SDK's parallel upload feature introduced in June 2016. Work-around the bug by turning off the feature with the following command:

gcloud config set app/num_file_upload_processes 1

The command above limits the number of parallel uploads to 1 thread/process, so they don't step on each other's feet.
