Single-Node etcd, multi-Master, and Multi-Worker Node Cluster. About Minikube Installation of Minikube ServerCreate the first POD using manifest file written in YAML LanguageKubelet commandsCheck logs of the containerCreate multiple containers in a POD Kubernetes AnnotationsVariables in the YAML fileDefining Ports Section 5: Kubernetes Pod Restart PolicyOverview of Pod Restart PoliciesThree restart policies: Always, OnFailure & NeverLab - Create a pod definition with ‘restartPolicy' as AlwaysLab - Create a pod definition with ‘restartPolicy' as OnFailureLab - Change the pod definition a bit to check the working of OnFailureLab - 4.

Create a pod definition with ‘restartPolicy' as NeverSection 6: Labels & SelectorsLabels & SelectorsCommands for managing labels & selectorsDeclarative vs. Imperative Kubernetes commandsTwo types Selectors Equality Based Set basedPractice Lab - Labels & SelectorsPractice Lab - Assign a label to the running PODPractice Lab - Search the pod with equality & set-based Node SelectorLab - Create a pod on a specific nodeSection 7: Scaling & ReplicationWhat is ReplicationController. Features of RCPractice Lab - Create Replicas of POD using RCPractice Lab - Recreate the POD, if it crashes, fails, or terminatedScale up & scale down the POD as the load increases Practice Lab - Scale up & scale down the PODWhat is ReplicaSet.

Difference between ReplicationController & ReplicaSetPractice Lab - Create Replicas of POD using ReplicaSetPractice Lab - Use set-based match expressions in RSSection 8: Deployment & RollbackOverview of Deployment and RollbackManifest for a POD with one container using the deployment object. Lab: Launch an application with two PODs using the deployment object. Lab: Using the deployment object, upgrade an application from version 1 to version 2.
