AWS Marketplace

Overview

You can use AWS Marketplace to directly launch a Weaviate cluster.

We use an AWS CloudFormation template for delivery.

Prerequisites
  • An AWS account with sufficient credit / payment method.
  • (Recommended) Familiarity with AWS and the AWS console.
What resources are used & installed?

This will set up the following resources:

  • EKS Cluster with a Single Node Group
    • In the default VPC or a fresh VPC with CIDR 10.0.0.0/16
  • Load Balancer Controller for EKS
  • aws-ebs-csi-driver for EKS
  • The latest selected version of Weaviate (e.g. 1.20.3 if you select 1.20)
    • This will be installed using our official Helm chart

AWS Marketplace

  1. Go to Weaviate's AWS Marketplace listing
  2. Subscribe to the product in AWS Marketplace by following the instructions on the page. At the time of writing (August 2023), the steps are to:
    1. Click Continue to Subscribe, then go to the next page
    2. Click Continue to Configuration, then go to the next page
    3. Select the fulfillment option & software version from the list. Then click Continue to Launch.
  3. Launch the software using a CloudFormation template (select the one for your preferred availability zone in the table below):

Configuration & Cluster creation

Before you get started

Some settings may not be changed after launch

Not all settings may be changed after launch. For example, these settings are currently not changeable after launch:

  • weaviatePVCSize
  • albDriver
  • ebsDriver
  • vpcUseDefault

Some settings may lead to recreation of the cluster

  • Changes to the instance type will lead to recreation of the node pool.

Suggested configurations

  • The default values should be suitable for a majority of cases.
  • weaviatePVCSize: For production environments, at least 500GB per StatefulSet pod is recommended. (Smaller disks may be sufficient for dev environments.)
  • weaviateAuthType: We recommend not running Weaviate with anonymous access. We suggest setting it to apikey and setting a key, for example by executing pwgen -A -s 32 to generate a random string.

Once you open the CloudFormation template, you should see a set of options similar to below.

Here, you can:

  1. Set the stack name for identifying the stack in AWS (required).
  2. Set Weaviate/AWS parameters, such as:
    • number of nodes
    • instance types
    • Weaviate authentication parameters.
  3. Confirm required resources & proceed to Create stack.
    • This template may require additional resources and capabilities.

After clicking Create stack, the creation process may take a while, such as around 30 minutes.

You can check the status of individual resources in the Events tab. Once the stack has been created, the status for the stack will change to ✅ CREATE_COMPLETE.

Accessing the cluster

Once the stack has been created, you can access the cluster using kubectl, and Weaviate itself using the load balancer.

Interaction using kubectl

You can run the following command which will update or create a kubeconfig file for the Weaviate cluster:

aws eks update-kubeconfig --name [cluster-name] --region [aws-region]--role-arn arn:aws:iam::[AccountID]:role/[StackName]-MastersRole[XX]
How to find the kubectl command

The exact command can be found in the CloudFormation stack, in the Outputs tab, under the EKSClusterConfigCommand output.

Once that's set up, you can run kubectl commands as usual. For example

  • kubectl get pods -n weaviate to list all pods in the weaviate namespace.
  • kubectl get svc --all-namespaces to list all services in all namespaces.

Finding the Weaviate URL

Once the stack has been created, you can access Weaviate via the load balancer URL.

You can find the Weaviate endpoint URL by any of:

  • Going to the Services section of AWS, under EC2 > Load Balancers. Find the load balancer, and look for the DNS name column.
  • Running kubectl get svc -n weaviate and looking for the EXTERNAL-IP of the weaviate service.

The load balancer URL (e.g. a520f010285b8475eb4b86095cabf265-854109584.eu-north-1.elb.amazonaws.com) will be the Weaviate URL (e.g. http://a520f010285b8475eb4b86095cabf265-854109584.eu-north-1.elb.amazonaws.com).

Deleting the cluster

You can delete the cluster by deleting the CloudFormation stack.

Please note that this will delete your data in Weaviate. If you want to keep your data, you should back it up or export the data before deleting the cluster.

Some resources many require manual deletion

caution

Please make sure that all unused resources are deleted. You will continue to incur costs for any remaining resources.

There may be some AWS resources that are not deleted automatically when the CloudFormation stack is deleted. For example, EBS volumes, and Key Management Service (KMS) keys may not be deleted from time to time.

You must delete these manually.

Tips

  • If your CloudFormation stack indicates "DELETE_FAILED", you may be able to re-initiate deletion of these resources.
  • Review the Resources tab of the CloudFormation stack to find resources that may not have been deleted.
  • Key Management Service (KMS) keys may be deleted by going to the KMS console, and deleting the keys manually. You may need to schedule deletion of the keys.

Billing

You will be charged for Weaviate and associated resources directly by AWS.

This will, for example, include the EC2 instances, EBS volumes, and any other resources used by the cluster.
