• AWS Prerequisites

To install Wallaroo in your AWS environment based on these instructions, the following prerequisites must be met:

• Register an AWS account: https://aws.amazon.com/ and assign the proper permissions according to your organization’s needs.
• The Kubernetes cluster must include the following minimum settings:
  • Nodes must be OS type Linux with using the containerd driver.
  • Role-based access control (RBAC) must be enabled.
  • Minimum of 4 nodes, each node with a minimum of 8 CPU cores and 16 GB RAM. 50 GB will be allocated per node for a total of 625 GB for the entire cluster.
  • RBAC is enabled.
  • Recommended Aws Machine type: c5.4xlarge. For more information, see the AWS Instance Types.
• Installed eksctl version 0.101.0 and above.
• If the cluster will utilize autoscaling, install the Cluster Autoscaler on AWS.

• AWS Cluster Recommendations

The following recommendations will assist in reducing the cost of a cloud based Kubernetes Wallaroo cluster.

• Turn off the cluster when not in use. An AWS EKS (Elastic Kubernetes Services) cluster can be turn off when not in use, then turned back on again when needed. If organizations adopt this process, be aware of the following issues:

  • IP Address Reassignment: The load balancer public IP address may be reassigned when the cluster is restarted by the cloud service unless a static IP address is assigned. For more information in Amazon Web Services see the Associate Elastic IP addresses with resources in your VPC user guide.

• Assign to a Single Availability Zone: Clusters that span multiple availability zones may have issues accessing persistent volumes that were provisioned in another availability zone from the node when the node is restarted. The simple solution is to assign the entire cluster into a single availability zone. For more information in Amazon Web Services see the Regions and Zones guide.

  The scripts and configuration files are set up to create the AWS environment for a Wallaroo instance are based on a single availability zone. Modify the script as required for your organization.

• Community Cluster Setup Instructions

The following is based on the requirements for Wallaroo Community. Note that Wallaroo Community does not use adaptive nodepools. Adapt the settings as required for your organization’s needs, as long as they meet the prerequisites listed above.

This sample YAML file can be downloaded from here:

wallaroo_community_aws_install.yaml

apiVersion: eksctl.io/v1alpha5
kind: ClusterConfig

metadata:
  # replace with the name of your server
  name: wallarooAWS
  # replace with your location
  region: us-east-1
  version: "1.25"

    desiredCapacity: 4
    containerRuntime: containerd
    amiFamily: AmazonLinux2
    availabilityZones:
      - us-east-1a

• Install AWS Command Line Tools

The following steps require the installation of the following Amazon Web Services command line tools:

• AWS CLI: Complete both the AWS Command Line Installation Guide and the AWS CLI Quick Setup Guide to authenticate to your AWS account.

• eksctl: A command line tool for managing Amazon EKS clusters from a configured YAML file. See the EKSCTL Install Guide for more details.

• kubectl: This interfaces with the Kubernetes server created in the Wallaroo environment.

• kots Version: Used to manage software installed in a Kubernetes environment.

• Create the Cluster

Create the cluster with the following command, which creates the environment and sets the correct Kubernetes version.

eksctl create cluster -f aws.yaml

During the process the Kuberntes credentials will be copied into the local environment. To verify the setup is complete, use the kubectl get nodes command to display the available nodes as in the following example:

kubectl get nodes

NAME                                           STATUS   ROLES    AGE     VERSION

  • Minimum of 4 nodes, each node with a minimum of 8 CPU cores and 16 GB RAM. 50 GB will be allocated per node for a total of 625 GB for the entire cluster.
  • RBAC is enabled.
  • Minimum machine type is set to to Standard_D8s_v4.

• Azure Cluster Recommendations

The following recommendations will assist in reducing the cost of a cloud based Kubernetes Wallaroo cluster.

• Turn off the cluster when not in use. An Azure Kubernetes Service (AKS) cluster can be turn off when not in use, then turned back on again when needed to save on costs. For more information on starting and stopping an AKS cluster, see the Stop and Start an Azure Kubernetes Service (AKS) cluster guide.

  If organizations adopt this process, be aware of the following issues:

  • IP Address Reassignment: The load balancer public IP address may be reassigned when the cluster is restarted by the cloud service unless a static IP address is assigned. For more information in Microsoft Azure see the Use a static public IP address and DNS label with the Azure Kubernetes Service (AKS) load balancer user guide.

• Assign to a Single Availability Zone: Clusters that span multiple availability zones may have issues accessing persistent volumes that were provisioned in another availability zone from the node when the cluster is restarted. The simple solution is to assign the entire cluster into a single availability zone. For more information in Microsoft Azure see the Create an Azure Kubernetes Service (AKS) cluster that uses availability zones guide.

  The scripts and configuration files are set up to create the Azure environment for a Wallaroo instance are based on a single availability zone. Modify the script as required for your organization.

• Manual Setup Guide

The following steps are guidelines to assist new users in setting up their Azure environment for Wallaroo. Feel free to replace these with commands with ones that match your needs.

See the Azure Command-Line Interface for full details on commands and settings.

The following are used for the example commands below. Replace them with your specific environment settings:

• Azure Resource Group: wallarooCEGroup
• Azure Resource Group Location: eastus
• Azure Container Registry: wallarooCEAcr
• Azure Kubernetes Cluster: wallarooCEAKS
• Azure Container SKU type: Base
• Azure Nodepool Name: wallarooCEPool

Setting up an Azure AKS environment is based on the Azure Kubernetes Service tutorial, streamlined to show the minimum steps in setting up your own Wallaroo environment in Azure.

This follows these major steps:

• Create an Azure Resource Group

• Create an Azure Container Registry

• Create the Azure Kubernetes Environment

• Set Variables

The following are the variables used in the environment setup process. Modify them as best fits your organization’s needs.

WALLAROO_RESOURCE_GROUP=wallaroocegroupdocs
WALLAROO_GROUP_LOCATION=eastus
WALLAROO_CONTAINER_REGISTRY=wallarooceacrdocs
WALLAROO_CLUSTER=wallarooceaksdocs
WALLAROO_SKU_TYPE=Base
WALLAROO_NODEPOOL=wallaroocepool
WALLAROO_VM_SIZE=Standard_D8s_v4
WALLAROO_CLUSTER_SIZE=4

• Create an Azure Resource Group

To create an Azure Resource Group for Wallaroo in Microsoft Azure, use the following template:

az group create --name $WALLAROO_RESOURCE_GROUP --location $WALLAROO_GROUP_LOCATION

(Optional): Set the default Resource Group to the one recently created. This allows other Azure commands to automatically select this group for commands such as az aks list, etc.

az configure --defaults group=$WALLAROO_RESOURCE_GROUP

• Create an Azure Container Registry

An Azure Container Registry(ACR) manages the container images for services includes Kubernetes. The template for setting up an Azure ACR that supports Wallaroo is the following:

az acr create -n $WALLAROO_CONTAINER_REGISTRY -g $WALLAROO_RESOURCE_GROUP --sku $WALLAROO_SKU_TYPE --location $WALLAROO_GROUP_LOCATION

• Create an Azure Kubernetes Services

And now we can create our Kubernetes service in Azure that will host our Wallaroo that meet the prerequisites. Modify the settings to meet your organization’s needs. This creates a 4 node cluster with a total of 32 cores.

az aks create \
--resource-group $WALLAROO_RESOURCE_GROUP \
--name $WALLAROO_CLUSTER \
--node-count $WALLAROO_CLUSTER_SIZE \
--generate-ssh-keys \

• Manual Setup Guide

The following steps are guidelines to assist new users in setting up their GCP environment for Wallaroo. Feel free to replace these with commands with ones that match your needs.

See the Google Cloud SDK for full details on commands and settings.

The commands below are set to meet the prerequisites listed above, and uses the variables as listed in Standard Setup Variables. Modify them as best fits your organization’s needs.

• Set Variables

The following are the variables used in the environment setup process. Modify them as best fits your organization’s needs.

WALLAROO_GCP_PROJECT=wallaroo-ce
WALLAROO_CLUSTER=wallaroo-ce
WALLAROO_GCP_REGION=us-central1
WALLAROO_NODE_LOCATION=us-central1-f
WALLAROO_GCP_NETWORK_NAME=wallaroo-network
WALLAROO_GCP_SUBNETWORK_NAME=wallaroo-subnet-1
WALLAROO_GCP_MACHINE_TYPE=e2-standard-8
WALLAROO_CLUSTER_SIZE=4

• Create a GCP Network

First create a GCP network that is used to connect to the cluster with the gcloud compute networks create command. For more information, see the gcloud compute networks create page.

gcloud compute networks \
create $WALLAROO_GCP_NETWORK_NAME \
--bgp-routing-mode regional \
--subnet-mode custom

Verify it’s creation by listing the GCP networks:

gcloud compute networks list

• Create the GCP Wallaroo Cluster

Once the network is created, the gcloud container clusters create command is used to create a cluster. For more information see the gcloud container clusters create page.

Note that three nodes are created by default, so one more is added with the --num-nodes setting to meet the Wallaroo prerequisites. For Google GKE, containerd is enabled by default and so does not need to be specified during the setup procedure: (https://cloud.google.com/kubernetes-engine/docs/concepts/using-containerd)[https://cloud.google.com/kubernetes-engine/docs/concepts/using-containerd].

gcloud container clusters \
create $WALLAROO_CLUSTER \
--region $WALLAROO_GCP_REGION \
--node-locations $WALLAROO_NODE_LOCATION \
--machine-type $WALLAROO_GCP_MACHINE_TYPE \
--num-nodes $WALLAROO_CLUSTER_SIZE \
--network $WALLAROO_GCP_NETWORK_NAME \
--create-subnetwork name=$WALLAROO_GCP_SUBNETWORK_NAME \
--enable-ip-alias \
--cluster-version=1.23

The command can take several minutes to complete based on the size and complexity of the clusters. Verify the process is complete with the clusters list command:

gcloud container clusters list

• Retrieving Kubernetes Credentials

Once the GCP cluster is complete, the Kubernetes credentials can be installed into the local administrative system with the the gcloud container clusters get-credentials (https://cloud.google.com/sdk/gcloud/reference/container/clusters/get-credentials) command:

gcloud container clusters \
get-credentials $WALLAROO_CLUSTER \
--region $WALLAROO_GCP_REGION

To verify the Kubernetes credentials for your cluster have been installed locally, use the kubectl get nodes command. This will display the nodes in the cluster as demonstrated below:

kubectl get nodes

NAME                                         STATUS   ROLES    AGE   VERSION
gke-wallaroo-ce-default-pool-863f02db-7xd4   Ready    <none>   39m   v1.21.6-gke.1503
gke-wallaroo-ce-default-pool-863f02db-8j2d   Ready    <none>   39m   v1.21.6-gke.1503
gke-wallaroo-ce-default-pool-863f02db-hn06   Ready    <none>   39m   v1.21.6-gke.1503
gke-wallaroo-ce-default-pool-3946eaca-4l3s   Ready    <none>   39m   v1.21.6-gke.1503

• Troubleshooting
  • What does the error ‘Insufficient project quota to satisfy request: resource “CPUS_ALL_REGIONS”’ mean?

Make sure that the Compute Engine Zone and Region are properly set based on your organization’s requirements. The instructions above default to us-central1, so change that zone to install your Wallaroo instance in the correct location.

In the case of the script, this would mean changing the region and location from:

WALLAROO_GCP_REGION=us-central1
WALLAROO_NODE_LOCATION=us-central1-f

WALLAROO_GCP_REGION={Your Region}
WALLAROO_NODE_LOCATION={Your Location}
