Prepare AWS Kubernetes

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.
