Workshop: Hands-on Kubernetes
summary
History of containers to hands-on labs with Docker (Dockerfile, docker build/run, Docker Hub) and Kubernetes (kubectl, kubelet, etcd, containerd), with demos that build a tagged unicorn image, run Flask/Unicorn containers and then deploy via YAML to pods, deployments and Services. Key claims: containers are leaky abstractions and running untrusted multi-tenant workloads without extra isolation (gVisor/Firecracker) is unsafe. Notes tooling limits: Docker has over 90 subcommands, clusters expose about 100 resource types. A lab bug shows Flask binding to localhost breaks ingress.
