How To Getting Started Azure Kubernetes Service

An overview of containers

Understanding containerisation is crucial before beginning to use Azure Kubernetes service.

Software development methods are increasingly using a notion called containerisation, much like the shipping industry uses physical containers to separate distinct cargoes to transport in ships, trains, trucks, and aeroplanes.

The code of an application, together with any necessary libraries, configuration files, and dependencies, are all bundled into a single software package called a container. As a result, developers and IT specialists may produce and implement applications more quickly and safely.

Isolation, portability, agility, scalability, and control over an application’s whole life cycle workflow are all advantages of containerisation. When a container is isolated from the host operating system, it may function independently and is more portable, enabling it to execute reliably and uniformly on any infrastructure and on any platform or cloud.

Azure Kubernetes Service: Components and ideas

The cluster

Azure Kubernetes Service is arranged as a cluster of on-premises or virtual machines at the top level. These devices referred to as nodes share storage, network, and processing power. One master node is linked to one or more worker nodes in each cluster. The master node controls which pods run on which worker nodes, while the worker nodes are in charge of executing pods, which are collections of containerised workloads and applications.

The control plane

Azure Kubernetes Service incorporates a variety of elements that together make up the control plane so that the master node may connect with the worker nodes and a human can communicate with the master node.

Using kubectl, a command-line interface that installs on their local operating system, developers and operators mostly communicate with the cluster through the master node. The kube-apiserver, the Kubernetes API located on the master node, receives commands sent to the cluster via kubectl. The master node’s kube-controller-manager, which is in charge of managing worker node activities, receives requests from the kube-apiserver. The kubelet on the worker nodes receives commands from the master node.

Deploying apps and workloads

App and workload deployment is the next phase in the Kubernetes process. The etc, a key value store database, is constantly updated by the master node with the current configuration and state of the Kubernetes cluster. You will use a YAML file to specify a new intended state to the cluster in order to launch pods with your containerised apps and workloads. Based on preset limitations, the kube-controller-manager uses the YAML file to instruct the kube-scheduler on which worker nodes the workload or application should execute on. The kube-scheduler, which coordinates with the kubelet of each worker node, initiates the pods, monitors the machine status, and oversees resource management.

The intended state that you specify becomes the current state in the etc in a Kubernetes deployment, but the prior state is preserved. Rollbacks, rolling updates, and halting roll outs are all supported by Kubernetes. Replica Sets are also used in the background by deployments to guarantee that the designated number of pods with the same configuration are operating. The Replica Set takes over in the event that one or more pods fail. Kubernetes is referred to as self-healing in this sense.

Structuring and securing Azure Kubernetes Service environments

The final stage in using Azure Kubernetes Service is to organise your workload or application and decide who or what can access it after it has been deployed. You can isolate services, pods, controllers, and volumes from other areas of the cluster while facilitating easy collaboration between them by establishing a namespace, a grouping approach within Kubernetes. Additionally, provide consistent configurations to resources by utilising the namespace notion in Azure Kubernetes Service.

Additionally, every worker node has a kube-proxy that controls how different cluster components can be accessible from the outside. Tokens, certificates, and passwords are examples of sensitive non-public data that should be kept in secrets, which are Azure Kubernetes Service objects that are encoded until execution.

Finally, use role-based access control (RBAC) to define who may see and interact with which areas of the cluster and how they can do so.
