Install Portworx on Elastic Kubernetes Service and EKS-D

This topic explains how to install Portworx on Amazon Web Services (AWS) Elastic Kubernetes Service (EKS) and EKS-D.

Prerequisites

• An AWS EKS cluster that meets the Portworx prerequisites
• You must have the supported disk types
• Recommended disk sizes:
  • GP2: 150 (GB) size disk is needed as the minimum IOP require.
  • GP3 specify IOPS required from EBS volume and specify throughput for EBS volume
  • IO1 specify IOPS required from EBS volume
• For production environments Portworx by Pure Storage recommends 3 Availability Zones (AZs)
• Portworx by Pure Storage recommends you set Max storage nodes per availability zone, Portworx will ensure that many storage nodes exist in the zone

note

• You can follow the same procedures explained in this topic to deploy Portworx on AWS Outposts.
• You can also follow the steps in this topic to install Portworx on EKS-D.
• For details on GP2, GP3, and IO1 performance characteristics, refer to the AWS documentation.

Create an IAM policy

Provide the permissions for all the instances in the autoscaling cluster by creating an IAM role.

Perform the following steps on your AWS Console:

For non-encrypted volumes

1. Navigate to the IAM page on your AWS console, then select Policies under the Identity and Access Management (IAM) sidebar section, then select the Create Policy button in the upper right corner:

   

2. Choose the JSON tab, then paste the following permissions into the editor, providing your own value for Sid if applicable. You can either use the minimum permissions required or use the permissions required for disk encryption:

   note

   These are the minimum permissions needed for storage operations for a Portworx cluster. For complete permissions required for all of Portworx storage operations, see the credentials reference.

           }
       ]
   }

3. Name and create the policy.

   

Attach IAM policy

Attach the above created policy to your Node instance role or user account.

Attach policy to a Node Instanace Role

Follow the instructions below for attaching the policy with your NodeInstanceRole:

1. From the IAM page, click Roles in the left pane.

2. On the Roles page, search for and select your nodegroup NodeInstanceRole using your cluster name. The following example shows eksctl-victorpeksdemo2-nodegroup-NodeInstanceRole-M9QTT58HQ9ZX as the nodegroup Instance Role:

   

   note

   If there are more than one nodegroup NodeInstanceRole for your cluster, attach the policy to those NodeInstanceRoles as well.

3. Attach the previously created policy by selecting Attach policies from the Add permissions dropdown on the right side of the screen:

   

4. Under Other permissions policies, search for your policy name. Select your policy name and select the Attach policies button to attach it.

   The policy you attached will appear under Permissions policies if successful:

   

Attach policy to your AWS user account

1. From the IAM page, click Users in the left pane.

2. On the Users page, search for and select your AWS user account.

3. On your user account detail page, click Add permissions in the upper right corner of the Permissions policies section.

4. Select Attach policies directly in the Permissions options section.

5. Use the search bar in the Permissions policies section to search and select your previously created policy, and click Next.

6. Click Add permissions to attach the policy to your AWS user account.

   Once the policy is successfully attached to your user account, you will be navigated back to your user account detail page and the policy will be listed in the Permissions policies section.

Deploy Portworx

Follow this section to deploy Portworx.

Generate specs

To install Portworx with Kubernetes, you must generate Kubernetes manifests that you will deploy in your cluster.

1. Navigate to Portworx Central and log in, or create an account, then follow the process to generate a spec.

2. Select Portworx Enterprise from the product catalog and click Continue.

3. On the Product Line page, choose any option depending on which license you intend to use, then select Continue to start the spec generator.

4. For Platform, select your K8s AWS as your cloud environment.

5. For Distribution Name, select Elastic Kubernetes Service (EKS).

6. Click Save Spec to generate the specs. You may customize the storage and network for your Portworx cluster if needed, by clicking on Customize.

important

As the PX-StoreV2 option is set to Auto, the Operator performs a pre-flight check across the cluster to determine if your cluster is capable of deploying Portworx with the PX-StoreV2 datastore. If the pre-flight check passes for each node, then PX-StoreV2 will be automatically selected as your default datastore during Portworx installation.

Apply specs

Apply the Operator and StorageCluster specs you generated in the section above using the kubectl apply command:

1. Deploy the Operator:

   kubectl apply -f 'https://install.portworx.com/<version-number>?comp=pxoperator'

   serviceaccount/portworx-operator created
   podsecuritypolicy.policy/px-operator created
   clusterrole.rbac.authorization.k8s.io/portworx-operator created
   clusterrolebinding.rbac.authorization.k8s.io/portworx-operator created
   deployment.apps/portworx-operator created

2. Deploy the StorageCluster:

   kubectl apply -f 'https://install.portworx.com/<version-number>?operator=true&mc=false&kbver=&b=true&kd=type%3Dgp2%2Csize%3D150&s=%22type%3Dgp2%2Csize%3D150%22&c=px-cluster-XXXX-XXXX&eks=true&stork=true&csi=true&mon=true&tel=false&st=k8s&e==AWS_ACCESS_KEY_ID%3XXXX%2CAWS_SECRET_ACCESS_KEY%3XXXX&promop=true'

   storagecluster.core.libopenstorage.org/px-cluster-xxxxxxxx-xxxx-xxxx-xxxx-8dfd338e915b created

Monitor Portworx nodes

1. Enter the following kubectl get command and wait until all Portworx nodes show as Online in the output:

   kubectl -n <px-namespace> get storagenodes -l name=portworx

   NAME                 ID                                     STATUS   VERSION          AGE

   username-k8s1-node2   xxxxxxxx-xxxx-xxxx-xxxx-e2169ffa111c   Online   2.11.1-3a5f406   4m52s

2. Enter the following kubectl describe command with the NAME of one of the Portworx nodes you retrieved above to show the current installation status for individual nodes:

   kubectl -n <px-namespace> describe storagenode <portworx-node-name>

   ...
   Events:

   note

   • In your output, the image pulled will differ based on your chosen Portworx license type and version.
   • For Portworx Enterprise, the default license activated on the cluster is a 30 day trial that you can convert to a SaaS-based model or a generic fixed license.
   • For Portworx Essentials, your cluster must have internet connectivity so that it can send usage information every 24 hours to renew the license on the cluster. You can convert an Essentials license to either a fixed license or SaaS-based license.

Verify your Portworx installation Once you've installed Portworx, you can perform the following tasks to verify that Portworx has installed correctly.

Verify if all pods are running Enter the following kubectl get pods command to list and filter the results for Portworx pods:

kubectl get pods -n <px-namespace> -o wide | grep -e portworx -e px

Create your first PVC

For your apps to use persistent volumes powered by Portworx, you must use a StorageClass that references Portworx as the provisioner. Portworx includes a number of default StorageClasses, which you can reference with PersistentVolumeClaims (PVCs) you create. For a more general overview of how storage works within Kubernetes, refer to the Persistent Volumes section of the Kubernetes documentation.

Perform the following steps to create a PVC:

1. Create a PVC referencing the px-csi-db default StorageClass and save the file:

kind: PersistentVolumeClaim
apiVersion: v1
metadata:
    name: px-check-pvc
spec:
    storageClassName: px-csi-db
    accessModes:
        - ReadWriteOnce
    resources:
        requests:
            storage: 2Gi

2. Run the kubectl apply command to create a PVC:

kubectl apply -f <your-pvc-name>.yaml

persistentvolumeclaim/example-pvc created

Verify your StorageClass and PVC

1. Enter the kubectl get storageclass command:

kubectl get storageclass

kubectl returns details about the StorageClasses available to you. Verify that px-csi-db appears in the list.

2. Enter the kubectl get pvc command. If this is the only StorageClass and PVC that you've created, you should see only one entry in the output:

kubectl get pvc <your-pvc-name>

NAME          STATUS   VOLUME                                     CAPACITY   ACCESS MODES   STORAGECLASS           AGE

kubectl returns details about your PVC if it was created correctly. Verify that the configuration details appear as you intended.
