Session Description: Currently Apache CloudStack supports two methods to deploy Kubernetes Clusters (CKS, CAPC). This session gives a demo on how to easily deploy CKS and CAPC on Apache CloudStack and will also give an overview of various use cases which will help you to choose the best deployment based on your requirement. http://docs.cloudstack.apache.org/en/latest/plugins/cloudstack-kubernetes-service.html https://cluster-api-cloudstack.sigs.k8s.io/getting-started.html Speakers Bio: For work, Kiran is a QR engineer at ShapeBlue. Kiran has experience in providing technical support on various issues related to CloudStack. Vishesh is a software engineer at ShapeBlue. He has experience in developing and managing cloud infrastructure. He has a particular interest in databases and has worked extensively on them. --------------------------------------------- On Friday 18th August, the Apache CloudStack India User Group 2023 took place in Bangalore, seeing CloudStack enthusiasts, experts, and industry leaders from across the country, discuss the open-source project. The meetup served as a vibrant platform to delve into the depths of Apache CloudStack, share insights, and forge new connections.

Lifecycle
Create, Scale, Upgrade, Delete

5. How CKS works
Prerequisites
Global settings
• Enable CKS (cloud.kubernetes.service.enabled)
• Endpoint URL (endpoint.url)) (http://<mgmt server ip>:8080/client/api)
• Register CKS ISO ( Kubernetes Binaries, Images, Config files )

6. • ./create-kubernetes-binaries-iso.sh OUTPUT_PATH KUBERNETES_VERSION CNI_VERSION CRICTL_VERSION

• 1.27.2, kubernetes version, see https://github.com/kubernetes/kubernetes/releases
• 1.3.0, CNI version, see https://github.com/containernetworking/plugins/releases
• 1.27.0, cri-tools version, see https://github.com/kubernetes-sigs/cri-tools/releases
• 1.11, weave addon for kubernetes, see https://github.com/weaveworks/weave/tree/master/prog/weave-kube
• 2.7.0, kubernetes dashboard version, see https://github.com/kubernetes/dashboard/release
