Terraform examples to launch Talos.

I store here the terraform code to launch Talos in the clouds. I wouldn't use the terrafrom modules from internet. The goal is to create all cloud services from scratch.

Ideas

First, I will create separate clusters on each cloud provider, test them thoroughly, and bring them close to production readiness. When I merge these separate Kubernetes clusters into one, they will have a single control plane.

Why is it so important?

Having a single Kubernetes control plane that spans multiple cloud providers can offer several benefits:

• Improved resilience and availability: By using multiple cloud providers, you can reduce the risk of downtime due to a single point of failure.
• Flexibility: A single control plane allows you to easily move workloads between different cloud providers, depending on your needs.
• Cost savings: You can take advantage of the different pricing models and discounts offered by different cloud providers to save on costs.
• Improved security: By using multiple cloud providers, you can implement a defense-in-depth strategy to protect your data and reduce the risk of a security breach.
• Decrease the time to recovery (TTR)

Clouds

Known issues

• Talos does not support Oracle CSI.

Multi cloud compatibility

CCM compatibility, which can work together:

• Talos CCM in mode: cloud-node
• Other CCMs in mode: cloud-node-lifecycle

Common

• cilium network with vxlan tunnels.
• ingress-nginx (daemonsets) runs on web role nodes. It uses hostNetwork ports 80,443 for optimizations. It helps me to tweak the kernel on a host and apply it to ingress controller. And I can disable conntrack too.
• coredns-local (daemonsets) uses dummy interface on al nodes and has ip 169.254.2.53 It decrease the dns response (all traffic does not leave the node).
• rancher.io/local-path as default storage class.
