Kubernetes is an open-source and portable software solution that helps in managing containerized workloads and services. It comes with a large growing ecosystem and it supports both declarative configuration and automation.
What Are Containers
Containers are software packages that consist of everything necessary for running software. In addition, it helps in building, testing, deploying, and redeploying applications in multiple environments. Containers are less overhead and they increase portability and efficiency and ensure better application development.
Features Of Kubernetes
- Sidecars- This feature allows you to run additional content within a pod. In addition, this additional container is helpful in directing data and exposing it to other containers in the pod.
- Helm Charts- It is useful in streamlining the installation and management of k8s applications. In addition, it uses packages and templates containing k8s manifest files.
- Custom Controllers- They help in regulating the state of your system or resources. Moreover, it helps in completing tasks that are not with standard controllers.
- Custom Scheduling- It is useful for assigning newly created pods to nodes. In addition, it is also helpful in handling special pods separately from others.
- Pod Disruption Budget (PDB)- PDB restricts the number of pools in a cluster that a user can stop voluntarily. Moreover, it ensures that a minimum number of pods stays active during tasks.
- Go Modules- These modules help in managing the application dependencies and allow a user to use multiple versions of the same dependency package.
- Taints and Tolerations- They direct nodes for “attracting” or “repelling” pods. Moreover, it helps in the deployment of an application on specific hardware.
- Cluster Federation- It treats multiple clusters as a single logical cluster and helps in easily managing clusters running in different locations or environments.
- Health Checking- It is useful for checking the health of pods or applications in k8. It consists of Readiness, Liveness, and Start-up to determine application health.
- Feature Gates- It is useful in turning features on or off on a node. In addition, it helps in safely testing features without risking critical components.
Benefits Of Using Kubernetes
Kubernetes comes with in-built commands that help in handling heavy lifting that goes into application management. In addition, it makes sure that apps are running the way you want them to run and allows you to automate various daily tasks. Above all, this software tool is capable of handling the compute, networking, and storage on behalf of your workloads. Thus, developers can concentrate on applications without worrying about the underlying environment. Kubernetes also ensures health monitoring and runs health checks against your services. To further learn about it, one can visit Kubernetes online course. Apart from these given below are some of the benefits of using Kubernetes.
- Improve your productivity
- Is a future proof solution
- Helps in making your application run more stable
- Is cost-effective and cheaper than its alternatives
Uses Of Kubernetes
Kubernetes results in increasing development velocity and allows you to build cloud-native microservices-based apps. In addition, it supports the containerization of existing apps, thus acting as a foundation of application modernization and allowing faster app development. This tool can be used anywhere and it allows a user to execute its applications across on-site deployments and public clouds. Thus, facilitating you to run your applications wherever you need them. Kubernetes is also beneficial in automatically scaling your applications as it can automatically adjust the size of a cluster necessary for running a service. Many institutions provide Kubernetes course in Delhi and one can enroll in them to learn this software tool. Here are some of the uses of Kubernetes
- Service discovery and load balancing
- Storage orchestration
- Automated rollouts and rollbacks
- Automatic bin packing
- It restarts containers that fail.
- Secret and configuration management
