Kubernetes that fits anywhere
Day 1
Installation, Architecture & Operations
- K3s architecture: Embedded SQLite vs external etcd vs PostgreSQL — choosing the right datastore
- Single-node and HA multi-server cluster installation: Step-by-step cluster setup with and without high availability
- Embedded components: Traefik ingress, local-path provisioner, Flannel CNI — what's included and why
- kubeconfig setup and kubectl usage with K3s: Connecting tools to your K3s cluster locally and remotely
- Air-gapped install: Preparing images and binaries for offline environments
- Replacing default components: Nginx instead of Traefik, Calico instead of Flannel — when and how to swap
- K3s agent configuration for edge nodes: Registering remote nodes with server-defined labels and taints
- Upgrades with the K3s auto-upgrade controller: Safe, automated Kubernetes version upgrades in place
What your team walks away with
A complete K3s operator — installing clusters from scratch, configuring storage and networking, and running upgrades safely.
- Install K3s single-node and HA clusters from scratch
- Configure and replace built-in components for your specific requirements
- Run K3s air-gapped in isolated environments
- Manage upgrades and node operations safely
