15 best Kubernetes Operators to look at in 2024

Understanding Kubernetes Operators

In the year 2016, the concept of Kubernetes Operator was formulated by CoreOS  engineer. The word Kubernetes means pilot or helmsman and it is originates from Ancient Greek. To handle, generate and configure the several applications on Kubernetes the Operators are created for ptarticular applications.

It is a process of control, deploying and packaging a Kubernetes application. But we know that Kubernetes offers limited functionality to ensure flexibility and scalability. This is where Kubernetes Operators act as Software Extensions that make use of Kubernetes APIs to extend a specific behavior or feature.

Kubernetes Operator interprets between both actions that are high-level action to low-level action that are implanted within the sense of operators. It puts up with the application-specific action and looks at a type of custom resource (CR) to create the recent state match in that resource. The Kubernetes operator regulates its application automatically as the data runs while having data backup plans that recover the data from the losses and within the time the application will update. The actions a Kubernetes operator performs can include almost anything: scaling a complex app, application version upgrades, or even managing kernel modules for nodes in a computational cluster with specialized hardware.

Understand Kubernetes as per Wikipedia: Kubernetes commonly abbreviated K8s is an open-source container orchestration system for automating software deployment, scaling, and management. Originally designed by Google, the project is now maintained by a worldwide community of contributors, and the trademark is held by the Cloud Native Computing Foundation.

Best Popular Kubernetes Operators 

1. RBAC Manager Operator

This operator assists declarative structure with the latest custom resources for RBAC and is formulated to facilitate approval in Kubernetes. It is focused on decreasing the quantity of configuration that mandates tremendous auth and it also delivers a declarative method that is more scalable and approachable to RBAC. If the configuration of RBAC is not proper then in the end many people are not connected or left with much more accessible as well several Kubernetes clusters.

2. MongoDB Enterprise Kubernetes Operator

For building a MongoDB instance into a repeatable, scalable and standardized procedure the MongoDB Enterprise Kubernetes Operator interprets the understanding of humans and for MongoDB cluster, Kubernetes Operator regulates the lifecycle exhibition. The Kubernetes operator merges with some of the further management tools of MongoDB such as MongoDB Cloud Manager and MongoDB Ops Manager and these tools come up with monitoring and backup.

3. HPA Kubernetes Operator

HPA is Horizontal Pod Auto scaler is executed as a controller and Kubernetes API resource as well the actions of the controller is determined by the resources. The scaled object does not relate to Horizontal Pod Auto scaler such as DaemonSets. HPA is supported by Kubernetes with two others the Vertical pod auto scaler and Auto scaling Kubernetes clusters. It is very simple to easily add the characteristics of pod auto scaling to Helm charts.

4. ArgoCD Operator

The whole data of the ArgoCD operator is maintained in the object of Kubernetes. For some users who want to operate Argo CD is a highly accessible description than a bundle of HA manifests are given to the users. The comprehensive life cycle of ArgoCD and its components is organized by ArgoCD Operator.

5. Istio Operator

Over microservices deployed on Kubernetes Istio Operator secure, monitor and organize the communication and it is very simple to install and upgrade this tool as well as easily it can solve the issues.

6. Etcd Operator

Etcd Operator is an Open source tool that is available on GitHub. The highly usable cluster on Kubernetes is formulated and protected by Etcd Operator. Some of the important features of this tool are it has an Automated update system with highly recommended backups and high availability.

7. Grafana Operator

It is an open-source platform that is formulated for organizing Grafana instances and monitoring. Some of the important characteristics of this you get to know more about this tool is you can configure Grafana Operator by custom resources and you can install this to a namespace.

8. Jaeger Kubernetes Operator

If you have to watch CR that means Jaeger custom resources then Jaeger Operator can install this and it supports managing, deploying, Jaeger samples on Kubernetes.

9. Portworx Operator

It has the config generator which you can regulate by hand or manually for the operator and it also provides several important pedagogy for utilizing Portworx on Openshift. It is used for production and gives for containerized applications the data safety, security and high availability.

10.KUDO

KUDO is Kubernetes Universal Declaration Operator. It is very important because it helps in the market faster and it saves time. It conserves time because there is no necessity to write a code. Some of the important features it enhanced the performance of the business, it has the CNCF Certified Partner.

11. MySQL Operator

It is also the important and main operator of Kubernetes that organizes the MYSQL InnoDB Cluster user Kubernetes Cluster and it also organizes the whole lifecycle with maintenance and setup that consists of backups and upgrades but automatically.

12. Kube Janitor

All the Kubernetes resources were eliminated on a configured expiry date, time to live and also refines all the name spaced resources. All name spaced resources CRD that mean custom resources definition.

13. Kubeplus

It’s open-source software that transmits its service by summarizing its consumer APIs. It is formulated for any application that is wrapped as a Helm chart.

14. Azure Service Operator

ASO means Azure Service Operator that attaches your application to the users within Kubernetes and also support you from the requirement Azure resources. It has two important versions that are v1and v2.

15. GitHub Actions Operator

GitHub Actions Operator is accessible with GitHub Enterprise Server, GitHub Team, GitHub AE, GitHub Free and GitHub Enterprise Cloud. It is only accessible for public storage not private.

Conclusion:  The Kubernetes operator regulates its application automatically as the data runs while having data backup plans that recover the data from the losses and within the time the application will update. In this blog we have explain some best Kubernetes operators and each plays an important role in the term Kubernetes. It represents a specific advancement in the realm of Kubernetes application management.
