Install Portworx on EKS air-gapped cluster


Follow the instructions on this page to deploy Portworx and its required packages on an EKS air-gapped cluster using your private registry location.

Prerequisites

  • You must have an AWS EKS cluster that meets the Portworx prerequisites.
  • You must use one of the following disk types:
    • GP2
    • GP3
    • IO1
  • Recommended disk sizes:
    • GP2: 150 (GB) size disk is needed as the minimum IOP requirement when running on AWS
    • GP3 specify IOPS required from EBS volume and specify throughput for EBS volume
    • IO1 specify IOPS required from EBS volume
  • For production environments Portworx, Inc. recommends 3 Availability Zones (AZs).
  • Portworx, Inc. recommends you to set Max storage nodes per availability zone.
  • A container registry accessible from the nodes on which Portworx will be deployed. In the below example, AWS Elastic Container Registry (ECR) is being used.
  • If using ECR, you must have AWS CLI installed and configured on your client machine.
  • An AWS user-account identity that can push or pull images to the given container registry.

Configure your environment

Follow the steps in this section to configure your EKS environment before installing Portworx.

Create an IAM policy

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

Perform the following steps from your AWS console:

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

    AWS create policy page

  2. Choose the JSON tab, then paste the following permissions into the editor, providing your own value for Sid if applicable:

    {
        "Version": "2012-10-17",
        "Statement": [
            {
                "Sid": "", 
                "Effect": "Allow",
                "Action": [
                    "ec2:AttachVolume",
                    "ec2:ModifyVolume",
                    "ec2:DetachVolume",
                    "ec2:CreateTags",
                    "ec2:CreateVolume",
                    "ec2:DeleteTags",
                    "ec2:DeleteVolume",
                    "ec2:DescribeTags",
                    "ec2:DescribeVolumeAttribute",
                    "ec2:DescribeVolumesModifications",
                    "ec2:DescribeVolumeStatus",
                    "ec2:DescribeVolumes",
                    "ec2:DescribeInstances",
                    "autoscaling:DescribeAutoScalingGroups"
                ],
                "Resource": [
                    "*"
                ]
            }
        ]
    }
    NOTE: These are the minimum permissions needed for storage operations for a Portworx cluster. For other IAM permissions required for other Portworx operations (such as backup and DR functionality), see the credentials reference section.
  3. Name and create the policy:

    Create policy

  4. In the Roles section, search and select your node group NodeInstanceRole using your cluster name. The following example shows eksctl-victorpeksdemo2-nodegroup-NodeInstanceRole-M9QTT58HQ9Z as the nodegroup Instance Role:

    Search for your policy

    NOTE: If there are more than one nodegroup NodeInstanceRole for your cluster, attach the policy to those NodeInstanceRoles as well.
  5. Attach the previously created policy by selecting Attach policies from the Add permissions dropdown on the right side of the screen:

    Attach your policy

  6. 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:

    Confirm your policy is added

    NOTE: Copy the ARN for the newly created policy. You will need to specify this value for your NodeGroup (either within the AWS create-EKS/nodegroup section if using the AWS console, or in a configuration file if using the eksctl) for all nodes in your AWS cluster.

Get Portworx container images

  1. Set an environment variable for the Kubernetes version you are using:

    KBVER=$(kubectl version --short | awk -F'[v+_-]' '/Server Version: / {print $3}')
  2. Set an environment variable to the latest major Portworx version:

    PXVER=<portworx-version>
  3. On an internet-connected host, download the air-gapped-install bootstrap script for the Kubernetes and Portworx versions that you specified:

    curl -o px-ag-install.sh -L "https://install.portworx.com/$PXVER/air-gapped?kbver=$KBVER"
  4. Pull the container images required for the specified versions:

    sh px-ag-install.sh pull

Set your container registry

In order to make the Portworx container images available in your air-gapped cluster, you need to have a container registry that the nodes can access. In the AWS environment, you can use the Elastic Container Registry (ECR) service. ECR is a repository for a single image, whereas Portworx consists of multiple images. Therefore, you must create a separate ECR repository for each image.

  1. Log in to docker:

    aws ecr get-login-password --region us-west-2 | docker login --username AWS --password-stdin XXXXXXXXXXXX.dkr.ecr.us-west-2.amazonaws.com
  2. Run the following command to create an ECR repository for each image. The following command will create repositories in the us-west-2 region, which are differentiated by the pxmirror prefix. You must use the region where you are deploying your Portworx cluster in the following command:

    for images in $(curl -fsSL install.portworx.com/$PXVER/air-gapped | awk -F / '/^IMAGES="$IMAGES /{print $NF}' | cut -d: -f1); do aws ecr create-repository --repository-name pxmirror/$images --image-scanning-configuration scanOnPush=true --region us-west-2; done

    You need to press q after the creation of each repository until the command is completely executed.

  3. Create the Kubernetes secret to pull the images in the same region:

     kubectl create secret docker-registry ecr-pxmirror --docker-server XXXXXXXXXXXX.dkr.ecr.us-west-2.amazonaws.com --docker-username=AWS --docker-password=$(aws ecr get-login-password --region us-west-2) -n kube-system

    The registry used in above command is:XXXXXXXXXXXX.dkr.ecr.us-west-2.amazonaws.com/pxmirror, where XXXXXXXXXXXX corresponds to your AWS Account ID number.

    NOTE: Skip the above steps if you are not using the ECR registry.
  4. Push the container images to a private registry that is accessible to your air-gapped nodes. Do not include http:// in your private registry path:

    sh px-ag-install.sh push XXXXXXXXXXXX.dkr.ecr.us-west-2.amazonaws.com/pxmirror

Create a version manifest configmap for Portworx Operator

  1. Download the Portworx version manifest:

    curl -o versions "https://install.portworx.com/$PXVER/version?kbver=$KBVER"
  2. Create a configmap from the downloaded version manifest:

    kubectl -n kube-system create configmap px-versions --from-file=versions

Install Portworx

Follow the instructions in this section to deploy Portworx.

Generate specs

  1. Navigate to the PX-Central.

  2. Select Portworx Enterprise from the product catalog.

  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. On the Basic page, ensure that the Use the Portworx Operator option is selected. For Portworx version, select the same version from the dropdown that you have set in the previous section. If you choose version 2.12, change the namespace to kube-system in the Namespace field. Select Built-in ETCD and click Next.

  5. Select Cloud as your environment and then select AWS as your cloud platform. Keep the recommended default values for the Configure storage devices section and click Next.

  6. Choose your network and click Next.

  7. On the Customize page, for the Are you running on either of these? option, select Amazon Elastic Container Service for Kubernetes (EKS). Provide your internal registry path and the details for how to connect to your private registry in Registry And Image Settings.

Click the Finish button to create the specs.

Apply specs

Apply the Operator and StorageCluster specs you generated in the section above by performing the following steps:

  1. Deploy the Operator:

    kubectl apply -f 'https://install.portworx.com/<PXVER>?comp=pxoperator'
    serviceaccount/portworx-operator created
    podsecuritypolicy.policy/px-operator created

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 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
    example-pvc   Bound    pvc-dce346e8-ff02-4dfb-935c-2377767c8ce0   2Gi        RWO            example-storageclass   3m7s

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