NETWORK_NOT_PEERED trying to create an AlloyDB instance through gcloud CLI


I'm trying to create an AlloyDB instance using the gcloud CLI using these commands:

gcloud alloydb clusters create default \
  --region=$LOCATION \
  --password=postgres
gcloud alloydb instances create default \
  --cluster=default \
  --region=$LOCATION \
  --cpu-count=2 \
  --instance-type=PRIMARY

The first command succeeds, but the second fails with:

service networking config validation failed NETWORK_NOT_PEERED - no peering found on network, see https://cloud.google.com/alloydb/docs/configure-connectivity for details

I believe I have to manually configure the peering network but I can't understand how? If I add the --enable-private-service-connect flag the instance is successfully created but then I'm unable to reach it from my GKE cluster, and I see the AlloyDB cluster has an empty "Network" entry.


Solution

  • I managed to create the instance with these commands:

    gcloud alloydb clusters create default \
      --region=$LOCATION \
      --password=postgres \
      --network=default
    
    gcloud compute addresses create servicenetworking-googleapis-com \
        --global \
        --purpose=VPC_PEERING \
        --addresses=192.168.0.0 \
        --prefix-length=16 \
        --network=default
    
    gcloud services vpc-peerings connect \
        --service=servicenetworking.googleapis.com \
        --ranges=servicenetworking-googleapis-com \
        --network=default
    
    gcloud alloydb instances create default \
      --cluster=default \
      --region=$LOCATION \
      --cpu-count=2 \
      --instance-type=PRIMARY
