  What is acontainer? Containers = operating system virtualization OS Kernel Applications Container Container Container Hardware Traditional virtual machines = hardware virtualization Hardware OS Application VM VM VM App OS App OS App OS

  Container orchestration • Creatinga single container is easy (especially when using Docker containers), even doing an application with 4 or 5 containers is easy • As soon as you get to production workloads with 10’s or hundreds of container images, scaling to thousands of running containers it gets hard • Orchestrator takes your containers and deploys them within a pool of virtual machines, then monitor their health as they run, load balancing them as required. • Historically orchestrators have been a pretty big pain to set up since each has a set of specific dependencies and expects a particular topology

  Azure Kubernetes Service(AKS) $ az aks create • -c == count of nodes / agents • Default 3, minimum 1 • -k == kubernets version you want • -s == node vm size (default standard ds1_v2) • --ssh-key-value my public key $ az aks get-credentials • Retrieves kubeconfig info from cluster and appends into current local kubeconfig $ kubectl get nodes
