Wallaroo Prerequisites Guide

Software and other local system requirements before installing Wallaroo

Before installing Wallaroo version, verify that the following hardware and software requirements are met.

Environment Hardware Requirements

The following system requirements are required for the minimum settings for running Wallaroo in a Kubernetes cloud cluster.

Minimum number of nodes: 4
Minimum Number of CPU Cores: 8
Minimum RAM per node: 16 GB
Minimum Storage: A total of 625 GB of storage will be allocated for the entire cluster based on 5 users with up to four pipelines with five steps per pipeline, with 50 GB allocated per node, including 50 GB specifically for the Jupyter Hub service. Enterprise users who deploy additional pipelines will require an additional 50 GB of storage per lab node deployed.

Wallaroo recommends at least 16 cores total to enable all services. At less than 16 cores, services will have to be disabled to allow basic functionality as detailed in this table.

For instructions on installing Wallaroo on a system with less than 16 cores, see the Install Wallaroo with Minimum Services.

Enterprise Network Requirements

The following network requirements are required for the minimum settings for running Wallaroo:

For Wallaroo Enterprise users: 200 IP addresses are required to be allocated per cloud environment.
For Wallaroo Community users: 98 IP addresses are required to be allocated per cloud environment.
DNS services integration is required for Wallaroo Enterprise edition. See the DNS Integration Guide for the instructions on configuring Wallaroo Enterprise with your DNS services.

DNS services integration is required to provide access to the various supporting services that are part of the Wallaroo instance. These include:
- Simplified user authentication and management.
- Centralized services for accessing the Wallaroo Dashboard, Wallaroo SDK and Authentication.
- Collaboration features allowing teams to work together.
- Managed security, auditing and traceability.

Environment Software Requirements

Running Wallaroo has two sets of software requirements:

Environment Requirements: The following software must be installed on the environment that will be running Wallaroo version. Most are automatically available through the supported cloud providers.
- Kubernetes Version 1.18 to 1.22.
  - Kubernetes Version
    - 1.20 is the minimum requirement
    - 1.21 is preferred for versions of Wallaroo released before July 2022.
    - 1.22:
      - Is preferred for versions of Wallaroo after the July 2022 release (code name Simca) and beyond.
      - Is not supported for versions of Wallaroo released before July 2022.
    - 1.23 is not yet supported
- Runtime: containerd is required.
Kubernetes Admin Requirements: The following software must be installed in the system where the Kubernetes environment is being managed - aka where kubectl and kots will be installed. This requires the following software be installed to manage the Kubernetes environment:
- kubectl: https://kubernetes.io/docs/tasks/tools/
- kots: https://docs.replicated.com/reference/kots-cli-getting-started
  - Version 1.81.0: Preferred for versions of Wallaroo after the August 2022 release (code name Mustang) and beyond.
  - Version 1.70.1: Preferred for versions of Wallaroo before the August 2022 release.

Node Selectors

Wallaroo uses different nodes for various services, which can be assigned to a different node pool to contain resources separate from other nodes. The following nodes selectors can be configured:

ML Engine node selector
ML Engine Load Balance node selector
Database Node Selector
Nifi Node Selector
Grafana node selector
Prometheus node selector
Each Lab * Node Selector

Cost Calculators

Organizations that intend to install Wallaroo into a Cloud environment can obtain an estimate of environment costs. The Wallaroo Install Guides list recommended virtual machine types and other settings that can be used to calculate costs for the environment.

For more information, see the pricing calculators for the following cloud services:

Kubernetes Admin Requirements

Before starting to install Wallaroo, the following requirements must be met at the local system level where Kubernetes commands are issued to the cluster:

kubectl: This interfaces with the Kubernetes server created in the Wallaroo environment.
kots: Used to manage software installed in a Kubernetes environment.
- Version 1.81.0: Preferred for versions of Wallaroo after the August 2022 release (code name Mustang) and beyond.
- Version 1.70.1: Preferred for versions of Wallaroo before the August 2022 release.

The following are quick guides on how to install the required software to install and perform updates to Wallaroo. See the respective web sites for full installation information.

kubectl Quick Install Guide

The following are quick guides for installing kubectl for different operating systems. For more details, see the instructions for your specific environment.

kubectl Install For Deb Package based Linux Systems

For users running a deb based package system such as Ubuntu Linux, the following commands will install kubectl and kots into the local system. They assume the user has sudo level access to the system.

Update the apt-get repository:
```
sudo apt-get update
```

Install the prerequisite software apt-transport-https, ca-certificates, and curl.

sudo apt-get install -y \
    apt-transport-https \
    ca-certificates curl

Download the install the Google Cloud repository key:

sudo curl -fsSLo \
    /usr/share/keyrings/kubernetes-archive-keyring.gpg \
    https://packages.cloud.google.com/apt/doc/apt-key.gpg

Install the Google Cloud repository into the local repository configuration:

echo "deb [signed-by=/usr/share/keyrings/kubernetes-archive-keyring.gpg] https://apt.kubernetes.io/ kubernetes-xenial main" \
    | sudo tee /etc/apt/sources.list.d/kubernetes.list

Update the apt-get repository, then install kubectl:

sudo apt-get update

sudo apt-get install -y kubectl

Verify the kubectl installation:
```
kubectl version --client
```

kubectl Install For macOS Using Homebrew

To install kubectl on a macOS system using Homebrew:

Issue the brew install command:
```
brew install kubectl
```
Verify the installation:
```
kubectl version --client
```

kots Quick Install Guide

The following are quick guides for installing kots for different operating systems. For more details, see the instructions for your specific environment.

IMPORTANT NOTE

As of this time, Wallaroo requires kots version 1.81.0. Please verify that version is installed before starting the Wallaroo installation process.

Install curl.
1. For deb based Linux systems, update the apt-get repository and install curl:
```
sudo apt-get update
sudo apt-get install curl
```
2. For macOS based systems curl is installed by default.
Install kots by downloading the script and piping it into the bash shell:
```
curl https://kots.io/install/1.81.0 | sudo bash
```

Manual Kots Install

A manual method to install KOTS is:

Download from https://github.com/replicatedhq/kots/releases/tag/v1.81.0. Linux and MacOS are supported.
Unpack the release
Rename the kots executable to kubectl-kots.
Copy the renamed kubectl-kots to anywhere on the PATH.

Next, verify successful installation.
