  • Improved security through secure access to external services
  • Increased efficiency in managing outgoing traffic
  • Enhanced scalability to handle large volumes of traffic

In short, the Longhorn egress gateway is vital for managing traffic from a cluster. Knowing its basics is key for safe and efficient access to outside services. By using its parts and design, users can boost security, efficiency, and growth.

System Requirements and Prerequisites

To deploy Longhorn in Kubernetes, knowing the system needs is key. The Longhorn egress gateway needs a Kubernetes cluster with the right Longhorn version. You’ll need at least 3 nodes, each with 4 CPUs and 4 GiB of RAM.

Also, a 100 GiB disk is suggested for a dedicated nodepool with Longhorn. This setup ensures Longhorn runs smoothly.

Setting up the cluster with Exoscale for Kubernetes (SKS) is also important. A 2-nodepool cluster is recommended. It should have 3 nodes in the general-purpose pool and 3 in the dedicated pool for Longhorn.

Creating an SKS cluster takes about 2 minutes and 9 seconds. Adding a nodepool for Longhorn takes around 3 seconds. This makes the setup efficient.

  • Kubernetes version 1.28.2 or later
  • Adequate CPU and memory resources for cluster workers
  • Existing workloads must have sidecars manually injected for tracking and control

By knowing these requirements, you can set up Longhorn in your Kubernetes environment well. This ensures the Longhorn egress gateway works effectively.

Preparing Your Environment for Longhorn Configuration

Before you start with Longhorn, getting your environment ready is key. You need to set up your network, think about security, and plan your resources. Doing this right helps avoid problems later on.

First, you must configure your network. This means setting up the Inband network and the container network. You also need to think about security, like firewall rules and SSL VPNs. Lastly, plan your resources, like storage and compute nodes, for the best performance.

Network Configuration Requirements

For your network, you need to set up the Inband, container, and service networks. The Inband network gets its own IP addresses, like the firewall and Kubernetes API. The container and service networks use /16 subnets for pods and services.

Security Considerations

Security is vital to keep your environment safe. You should block incoming traffic unless it’s through an SSL VPN. Also, allow all outgoing internet traffic. The FortiGate firewall, in high availability mode, adds extra security.

Resource Allocation Guidelines

When allocating resources, think about your storage and compute nodes. Different storage options have different speeds. Make sure you have enough compute nodes for the best performance. Your private cloud connects via an SSL VPN for access to the Rancher dashboard and Kubernetes API.

By following these steps, you can get your environment ready for Longhorn. This includes setting up your network, thinking about security, and planning your resources. This way, you can avoid problems and have a smooth experience.
