Configure a VPC network

Google Cloud Managed Lustre runs within a Virtual Private Cloud (VPC) which provides networking functionality to Compute Engine virtual machine (VM) instances, Google Kubernetes Engine (GKE) clusters, and serverless workloads.

The same VPC network must be specified when creating the Managed Lustre instance and client Compute Engine VMs or Google Kubernetes Engine clusters.

You must also configure private services access within your VPC.

Required permissions

You must have the following IAM permissions:

  • serviceusage.services.enable
  • compute.networks.create
  • compute.addresses.create
  • compute.addresses.get
  • compute.firewalls.create
  • servicenetworking.services.addPeering

These permissions can be granted by adding all of the following predefined roles:

Or, create a custom role containing the specific permissions.

To grant a role to a user:

gcloud projects add-iam-policy-binding PROJECT_ID \
  --member="user:EMAIL_ADDRESS"
  --role=ROLE

Create and configure the VPC

  1. Enable service networking.

    gcloud services enable servicenetworking.googleapis.com

  2. Create a VPC Network.

    gcloud compute networks create NETWORK_NAME \
  --subnet-mode=auto \
  --mtu=8896

  3. Create an IP range.

    gcloud compute addresses create IP_RANGE_NAME \
  --global \
  --purpose=VPC_PEERING \
  --prefix-length=20 \
  --description="Managed Lustre VPC Peering" \
  --network=NETWORK_NAME

  4. Get the CIDR range associated with the range you created in the previous step.

    CIDR_RANGE=$(
  gcloud compute addresses describe IP_RANGE_NAME \
    --global  \
    --format="value[separator=/](address, prefixLength)"
)

  5. Create a firewall rule to allow TCP traffic from the IP range you created.

    gcloud compute firewall-rules create FIREWALL_NAME \
  --allow=tcp:988,tcp:6988 \
  --network=NETWORK_NAME \
  --source-ranges=$CIDR_RANGE

  6. Connect the peering.

    gcloud services vpc-peerings connect \
  --network=NETWORK_NAME \
  --ranges=IP_RANGE_NAME \
  --service=servicenetworking.googleapis.com
