Meetup Estonia, talk about Azure AKS and ACI Connector
- 1. Kubernetes spare leg (node) or why virtual kubelet Evgeny Rudinsky @aws-ee co-founder, committee member
- 2. About my-self • Cyclist • Azure and AWS fan • A bit of software dev • Currently with Microsoft • twitter.com/evgenyrudinsky
- 4. From traditional app to modern app Existing Application APP Modern Microservices Add new services or start peeling off services from monolithic code. Modern Methodologies Implement DevOps practices and automation. Modern Infrastructure Move to the cloud as VMs or Containers or refresh HW. Containerize Applications Re-architect apps for scale with containers.
- 5. Containers vs virtualization Virtualization Containerization Type 1 Hardware Hypervisor 1 VM VM VM Hardware Type 2 Host OS Hypervisor 2 VM VM VM Virtual machine Guest OS Dependencies Application Hardware Host OS Docker Engine Dependency 1 Dependency 2 C C C C C Container App dependencies Application XYZ
- 6. Containers • Docker inc. • In 2013 • San Francisco, CA • Has became a de facto standard for containers Docker engine example: $ docker run busybox
- 7. Ok, I’m convinced, but wait..
- 8. The World of orchestrators • Docker Machine: Provisions hosts and installs Docker Engine (the lightweight runtime and tooling used to run Docker containers) software on them. • Docker Swarm: Produces a single, virtual Docker host by clustering multiple Docker hosts together. It presents the same Docker API; allowing it to integrate with any tool that works with a single Docker host. • Docker Compose: Takes a file defining a multi-container application (including dependencies) and deploys the described application by creating the required containers. It is mostly aimed at development, testing, and staging environments. • Kubernetes: was created by Google and is one of the most feature-rich and widely used orchestration frameworks. • Other systems.
- 9. κυβερνήτης Nautical term means “helmsmen” or “pilot” .. shortcut “k8s”
- 11. Virtual kubelet
- 12. Azure Container Registry “ACR“ Private registry in Azure cloud for images Use docker CLI Geo-replicationControl any image type
- 13. Azure Container Instances “ACI” Managed containers (containers as a service) Scale for any tasks Hypervisor isolationEasy and now
- 14. Azure Kubernetes Service “AKS” Managed k8s in Azure (not access to master) Use open source API as you like it Scale and don’t worry, check SLA Keep your development, Azur takes care of ifrastructure
- 15. ACI connector for K8s Kubernetes control pane Application architect Infrastructure architect Azure Container Instances (ACI) ACIConnector Pod Pod Pod Pod Pod Pod Pod Pod Pod Pod Pod Pod VM VM VM VM Deployment/ tasks Pod Pod Pod Pod Pod Pod Pod Pod Pod Pod Pod Pod Pod Pod Pod Pod Pod Pod Pod Pod Pod Pod Pod Pod Pod WasteWaste WasteWaste
- 16. Similar in AWS
- 17. Enough talk … $ az aks create –g RG –n k8s $ az aks install-cli $ az aks get-credentials –g RG –n k8s $ az aks show –o table Name Location ResourceGroup KubernetesVersion ProvisioningState Fqdn ------ ---------- --------------- ------------------- ------------------- ------------------------------------------------ AKS westeurope AKS 1.9.6 Succeeded aks-aks-f4dac7-ec5bfba9.hcp.westeurope.azmk8s.io $ kubectl get nodes NAME STATUS ROLES AGE VERSION aks-nodepool1-26874413-0 Ready agent 3m v1.9.6 aks-nodepool1-26874413-1 Ready agent 3m v1.9.6 aks-nodepool1-26874413-2 Ready agent 3m v1.9.6
- 18. Show me the code .. // make sure you have helm (brew install kubernetes-helm for mac) $ az aks install-connector --resource-group AKS --name AKS --connector-name aciconnector $ kubectl get nodes NAME STATUS ROLES AGE VERSION aks-nodepool1-26874413-0 Ready agent 6m v1.9.6 aks-nodepool1-26874413-1 Ready agent 6m v1.9.6 aks-nodepool1-26874413-2 Ready agent 6m v1.9.6 virtual-kubelet-aciconnector-linux-westeurope Ready agent 1m v1.8.3 $ kubectl create –f helloworld.yaml
- 19. Everything for containers in Azure • ACR – Azure Container Registry (private registry for images) • ACI – Azure Container Instances (container as a service, aka “CaaS”) • AKS - Azure Kubernetes Service (managed k8s cluster in Azure) • ACS – Azure Container Services (asc-engine based on ARM templates for Docker Swarm, DS/OS or K8s), you have access to master node • IaaS – fully managed by you cluster of containers and orchestrator of you choice (in short, - set of VMs)
- 20. Quick demo
- 21. CaaS with orchestration together • Of course you can launch “Mario” :) • … • Spare node for development / test • No need to keep “adult” node with small load • Pay-as-you-go with your container (i.e. per second in Azure ACI) • Your choice
- 22. Resources • Bursting from AKS to ACI with the Virtual Kubelet – instruction how to get started with virtual kubelet and AKS • Virtual kubelet project on github • Virtual kubelet explained • Supermario docker image • Azure Portal (you can get started with free money on it first time) • Azure Pricing Calculator – to estimate your expenses • AWS Fargate and EKS • Kubectl cheat sheet
- 23. Other useful resources Create RBAC for ACR $ az ad sp create-for-rbac --scopes /subscriptions/<SUBSCRIPTION_ID>/resourcegroups/<ACR_RG_NAME>/prov iders/Microsoft.ContainerRegistry/registries/<ACR_NAME> --role Contributor --name <ROLE_NAME> Create secret for pull images from ACR $ kubectl create secret docker-registry <NAME> --docker-server <ACR_NAME>.azurecr.io --docker-email <EMAIL> --docker- username=<APP_ID> --docker-password=<APP_SECRET>
