As from your question I could figure out that resources unavailable for the europe-west1-b
zone possibly due to the type and size of VM that you requested is currently unavailable in the zone that you requested it in.
Refer to official GCP Troubleshooting resource availability errors :
Resource errors occur when you try to request resources in a zone that
cannot accommodate your request due to the current unavailability of a
Compute Engine resource, such as GPUs or CPUs.
The best way to resolve a resource error is to
retry the request in a different zone, at a different time, or with a different VM configuration or try again later.
If you're requesting multiple VMs, try one or more of the following:
- Request the VMs in another zone.
- If your workload permits, request a zonal or regional SSD persistent disk instead of local SSD.
- Split your local SSD request into multiple VMs. For example, if you requested one VM with 600GB of local SSD, divide the request into
several VMs that have a total combined local SSD of 600GB.
