aws docdb restore-db-cluster-from-snapshot

Question

Hello,

When I want to restore the snapshoot docdb shared with me, I get the following error.

```
aws docdb restore-db-cluster-from-snapshot \
    --db-cluster-identifier   \
    --snapshot-identifier  \
    --engine docdb \
    --kms-key-id <123>
```

**An error occurred (InvalidSubnet) when calling the RestoreDBClusterFromSnapshot operation: No default subnet detected in VPC. Please contact AWS Support to recreate default Subnets.**

Thank you for your help

Accepted Answer

Hello.

I think that if you do not specify a subnet group name with "--db-subnet-group-name" in the command options, it will start in the subnet in the default VPC.  
Therefore, I think you need to create the subnet group yourself and then specify it, or contact AWS Support as mentioned in the error message to re-create the default VPC and configure the subnet.  
If you already have a subnet group, I think it's easiest to specify that subnet group as an option.
