AWS Install Prerequisites

Konvoy prerequisites

Before you begin using Konvoy, you must have:

An x86_64-based Linux or macOS machine.
The dkp binary for Linux, or macOS.
Docker version 18.09.2 or later installed.
kubectl for interacting with the running cluster.
A valid AWS account with credentials configured.

NOTE: On macOS, Docker runs in a virtual machine. Configure this virtual machine with at least 8GB of memory.

Control plane nodes

You should have at least three control plane nodes. Each control plane node should have at least:

4 cores
16 GiB memory
Approximately 80 GiB of free space for the volume used for /var/lib/kubelet and /var/lib/containerd.
Disk usage must be below 85% on the root volume.

DKP on AWS defaults to deploying an m5.xlarge instance with an 80GiB root volume for control plane nodes, which meets the above requirements.

Worker nodes

You should have at least four worker nodes. The specific number of worker nodes required for your environment can vary depending on the cluster workload and size of the nodes. Each worker node should have at least:

8 cores
32 GiB memory
Around 80 GiB of free space for the volume used for /var/lib/kubelet and /var/lib/containerd.
Disk usage must be below 85% on the root volume.

DKP on AWS defaults to deploying am5.2xlarge instance with an 80GiB root volume for worker nodes, which meets the above requirements.

If you use these instructions to create a cluster on AWS using the DKP default settings without any edits to configuration files or additional flags, your cluster is deployed on an Ubuntu 20.04 operating system image with 3 control plane nodes, and 4 worker nodes which match the requirements above.

NOTE: Using these default images work, but due to missing optimizations, the created cluster will have certain limits. We suggest using Konvoy Image Builder to create a custom AMI to take advantage of enhanced cluster operations.

AWS prerequisites

Before you begin using Konvoy with AWS, you must:

Create an IAM policy configuration.
Understand IAM Policies and Roles.
Export the AWS region where you want to deploy the cluster:
CODE
```
export AWS_REGION=us-west-2
```
Export the AWS profile with the credentials you want to use to create the Kubernetes cluster:
CODE
```
export AWS_PROFILE=<profile>
```
