AWS Marketplace

This topic provides instructions for installing Portworx via the Amazon Marketplace on EKS (Elastic Kubernetes Service). Follow the steps in this topic in order.

Prepare your EKS Cluster

Before you can install Portworx, you must configure AWS permissions:

Grant Portworx the needed AWS permissions

Portworx creates and attaches EBS volumes. As such, it needs the AWS permissions to do so. Below is a sample policy describing these permissions:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "<stmt-id>",
            "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": [
                "*"
            ]
        }
    ]
}

You can provide these permissions to Portworx in one of the following ways:

• Instance Privileges: Provide above permissions for all the instances in the autoscaling cluster by applying the corresponding IAM role. More info about IAM roles and policies can be found here
• Environment Variables: Create a User with the above policy and provide the security credentials (AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY) to Portworx.

Configure IAM permissions

You can configure the IAM permissions in multiple ways. Follow the steps most appropriate for you:

Configure with eksctl

If you created your cluster with eksctl this would be your best option. If you did not check out the section about configuring your cluster with AWS CLI or AWS Console

1. Before you can create an IAMServiceAccount for Portworx, you must enable the IAM OIDC Provider for your EKS cluster. Make sure to replace <clustername> with your EKS cluster and change the region if you are not running in us-east-1

   eksctl utils associate-iam-oidc-provider --region=us-east-1 --cluster=<clustername> --approve

2. Now you can create the IAMServiceAccount with the appropriate permissions. (you need these permissions to send metering data to AWS) Make sure to change the namespace if you are not deploying in kube-system and make sure to replace <clustername> with your EKS cluster.

   eksctl create iamserviceaccount --name portworx-aws --namespace kube-system --cluster <clustername> --attach-policy-arn arn:aws:iam::aws:policy/AWSMarketplaceMeteringFullAccess \
   --attach-policy-arn arn:aws:iam::aws:policy/AWSMarketplaceMeteringRegisterUsage --approve --override-existing-serviceaccounts

This will create an IAMServiceAccount on the AWS Console and will create a ServiceAcccount in the requested namespace, which we will pass to our helmchart in the next section

Configure with AWS CLI or AWS Console

You can configure IAM permissions through the AWS CLI or AWS Console. For instructions on configuring these permissions, refer to the Amazon documentation:

• for AWS CLI go here: AWS CLI
• for AWS Console go here: AWS Console

Use the correct namespace and serviceaccount you defined in the steps above.

Install

Once you've prepared your EKS cluster, you can install Portworx.

note

If you are not using instance privileges, you must also specify AWS environment variables in the Helm install parameters. Specify the following environment variables:

--set env="AWS_ACCESS_KEY_ID=<id>\,AWS_SECRET_ACCESS_KEY=<key>"

Add the Helm repository

Add the Portworx AWS Helm repository by running the following helm command:

helm repo add portworx https://raw.githubusercontent.com/portworx/aws-helm/master/stable

Install the helm chart from the repository

To install the chart with the release name my-release run the following commands substituting relevant values for your setup. Refer to the Helm chart configuration reference for information about the configurable parameters:

helm install my-release portworx/portworx --set storage.drives="type=gp2\,size=1000" --set serviceAccount="portworx-aws"

Specify each parameter using the --set key=value[,key=value] argument to helm install.

note

• clusterName should be a unique name identifying your Portworx cluster. The default value is mycluster, but it is suggested to update it with your naming scheme.
• storage.drives has been set to 1 TB, if you wish to have smaller storage drives please change that setting.

Upgrade or reconfigure Portworx

When Portworx releases new versions, you can upgrade it through Helm. You can also reconfigure Portworx through Helm by peforming upgrade operations, even if there is no new version to upgrade to. Perform the following steps to upgrade or reconfigure Portworx:

1. Upgrade the Helm repository to make sure you have the latest version of the Helm chart by running the following helm command:

   helm repo update

2. Upgrade or reconfigure Portworx by running the upgrade command and specifying the same options you used when you installed Portworx, or new options if you want to reconfigure Portworx. For Example:

   helm upgrade my-release portworx/portworx --set storage.drives="type=gp2\,size=1000" --set serviceAccount="portworx-aws"

Uninstall Portworx

Perform the following steps to uninstall Portworx:

1. Edit the storage cluster:

   kubectl -n <namespace> edit storagecluster <yourclustername>

2. Add the following lines to your YAML spec section:

   deleteStrategy:
     type: UninstallAndWipe

3. Save the spec and exit out.

4. Delete the storagecluster:

   kubectl -n <namespace> delete storagecluster <yourclustername>

5. Once all the portworx related pods are gone, uninstall/delete the my-release deployment:

   helm delete my-release

   This command removes all the Kubernetes components associated with the chart and deletes the release.

Helm chart configuration reference

The following tables lists the configurable parameters of the Portworx chart and their default values.

Parameter	Description
awsProduct	Portworx Product Name, PX-ENTERPRISE or PX-ENTERPRISE-DR (Defaults to PX-ENTERPRISE)
clusterName	Portworx Cluster Name
namespace	Namespace in which to deploy portworx (Defaults to kube-system)
storage.usefileSystemDrive	Should Portworx use an unmounted drive even with a filesystem ?
storage.usedrivesAndPartitions	Should Portworx use the drives as well as partitions on the disk ?
storage.drives	Semi-colon separated list of drives to be used for storage (example: "/dev/sda;/dev/sdb"), to auto generate amazon disks use a list of drive specs (example: "type=gp2\,size=150";type=io1\,size=100\,iops=2000"). Make sure you escape the commas
storage.journalDevice	Journal device for Portworx metadata
storage.maxStorageNodesPerZone	Indicates the maximum number of storage nodes per zone. If this number is reached, and a new node is added to the zone, Portworx doesn’t provision drives for the new node. Instead, Portworx starts the node as a compute-only node.
network.dataInterface	Name of the interface <ethX>
network.managementInterface	Name of the interface <ethX>
secretType	Secrets store to be used can be aws-kms/k8s/none defaults to: k8s
envVars	semi-colon-separated list of environment variables that will be exported to portworx. (example: MYENV1=val1;MYENV2=val2)
serviceAcccount	Name of the created service account with required IAM permissions

Specify each parameter using the --set key=value[,key=value] argument to helm install.
