This page describes the software, hardware, and networking requirements for the nodes where Shipa will be installed.

📘

This document applies only to Self-Managed Shipa. If, instead, you prefer Shipa Cloud, please visit https://apps.shipa.cloud and register. From there on, you can add existing Kubernetes cluster to be managed by Shipa Cloud by following the instructions in Connecting Clusters.

Typical Shipa Self-Managed Topology

Shipa has a control plane to a many workload cluster relationship.

Kubernetes Clusters

Today, Shipa supports Kubernetes clusters versions 1.19 and higher up to 1.22.

Tested and supported clusters are:

• On-premises clusters
• Minikube
• GKE (Google Kubernetes Engine)
• AKS (Azure Kubernetes Service)
• EKS (Amazon Elastic Kubernetes Service)
• OKE (Oracle Kubernetes Engine)
• LKE (Linode Kubernetes Engine)
• DOKS (DigitalOcean Kubernetes)

🚧

Single-zone clusters

Only single-zone clusters are supported on Shipa's free version.

Container Runtime Requirements

Shipa currently supports only 64-bit x86 Linux nodes.

It is tested with ContainerD and Docker as container runtime. However, it should work in any runtime that implements Container Runtime Interface (CRI).

CPU and Memory

Hardware requirements scale based on the size of your deployment that is controlled by Shipa. These resource consumptions are at the node level, nodes where Shipa will be installed.

Networking Requirements

During the install, Shipa Self-Managed by default creates and uses two public IPs for Load Balancers. These Load Balancer services expose some of the Shipa services, using the following ports:

By default, during the install, Shipa uses dynamic public IP set by the cloud provider. If preferred, static IP can be used instead by applying the optional parameter below when using Helm install:

--set shipaCluster.ingress.ip=<Static IP>

Ingress requirements

Shipa supports nginx (default), istio and traefik ingress controllers for main install cluster as well as connected clusters (Self hosted as well as Shipa Cloud). See table below for supported versions of these ingress controllers and Cert Manager:

There are several options for the Shipa Self-Managed ingress: Shipa Ingress Choices
