part 0 - before you start

Notes before you read:

• k8s = kubernetes
• this post assumes you know how to use docker
• if you don’t have a k8s cluster but still want to play with k8s you can easily setup a very lightweight cluster with k3s.io. It’s a single binary that eats about 0.5GB of RAM and a bit of CPU
• advanced k8s users - go away, this post is not for you and contains heresy (on purpose, to make stuff easier)

What this post will teach you:

• what is a pod, deployment, service, ingress, namespace
• how to create k8s application configuration
• how to debug deployed application
• common pitfalls

What this post will not teach you:

• how to manage your k8s cluster
• how to do load balancing
• what is a DaemonSet, ClusterRole, ClusterRoleBinding, ServiceAccount, etc.
• how to dance
