Getting started with Hopsworks.ai (AWS)#

This guide goes into detail for each of the steps of the cluster creation in Hopsworks.ai

Step 1 starting to create a cluster#

In Hopsworks.ai, select Create cluster:

Step 2 setting the General information#

Select the Region in which you want your cluster to run (1), name your cluster (2).

Select the Instance type (3) and Local storage (4) size for the cluster Head node.

Select the number of workers you want to start the cluster with (5). Select the Instance type (6) and Local storage size (7) for the worker nodes.

Note

It is possible to add or remove workers once the cluster is running.

Enter the name of the S3 bucket (8) you want the cluster to store its data in, in S3 bucket.

Note

The S3 bucket you are using must be empty.

Press Next (9):

Create a Hopsworks cluster, general Information — Create a Hopsworks cluster, general information

Step 3 select an SSH key#

When deploying clusters, Hopsworks.ai installs an ssh key on the cluster's instances so that you can access them if necessary. Select the SSH key that you want to use to access cluster instances. For more detail on how to add a shh key in AWS refer to Create an ssh key

Step 4 select the Instance Profile:#

To let the cluster instances access the S3 bucket we need to attach an instance profile to the virtual machines. In this step, you choose which profile to use. This profile needs to have access right to the S3 bucket you selected in Step 2. For more details on how to create the instance profile and give it access to the S3 bucket refer to Creating an instance profile and giving it access to the bucket

Choose the instance profile

Step 5 set the backup retention policy:#

Note

This step is only accessible to enterprise users.

To back up the S3 bucket data when taking a cluster backup we need to set a retention policy for S3. In this step, you choose the retention period in days. You can deactivate the retention policy by setting this value to 0 but this will block you from taking any backup of your cluster.

Step 6 Managed Containers:#

Hopsworks can integrate with Amazon Elastic Kubernetes Service (EKS) and Amazon Elastic Container Registry (ECR) to launch Python jobs, Jupyter servers, and ML model servings on top of Amazon EKS. For more detail on how to set up this integration refer to Integration with Amazon EKS and Amazon ECR.

Step 7 VPC selection#

In this step, you can select the VPC which will be used by the Hopsworks cluster. You can either select an existing VPC or let Hopsworks.ai create one for you. If you decide to let Hopsworks.ai create the VPC for you, you can choose the CIDR block for this virtual network. Refer to Create a VPC for more details on how to create your own VPC in AWS.

Step 8 Availability Zone selection#

If you selected an existing VPC in the previous step, this step lets you select which availability zone of this VPC to use.

If you did not select an existing virtual network in the previous step Hopsworks.ai will create an availability zone for you. You can choose the CIDR block this subnet will use.

Choose subnet — Choose an availability zone

Step 9 Security group selection#

If you selected an existing VPC in the previous step, this step lets you select which security group to use.

Note

For Hopsworks.ai to create the SSL certificates the security group needs to allow inbound traffic on port 80.

If you intend to use the managed users option on your Hopsworks cluster you should also add a rule to open port 443.

Step 10 User management selection#

In this step, you can choose which user management system to use. You have three choices:

Managed: Hopsworks.ai automatically adds and removes users from the Hopsworks cluster when you add and remove users from your organization.
LDAP: integrate the cluster with your organization's LDAP/ActiveDirectory server.
Disabled: let you manage users manually from within Hopsworks.

Step 11 add tags to your instances.#

In this step, you can define tags that will be added to the cluster virtual machines.

Step 12 Review and create#

Review all information and select Create:

The cluster will start. This will take a few minutes:

As soon as the cluster has started, you will be able to log in to your new Hopsworks cluster with the username and password provided. You will also be able to stop, restart, or terminate the cluster.
