A Kubernetes operator is an operator that is used as a method of building and driving an application on top of Kubernetes. You can easily use Kubernetes tools to help you solve the problem of a complex application. Ultimately, a Kubernetes operator works to help extend the types of applications that you can run on it, thus taking pressure off your IT team. The IT team writes the software to capture all operational considerations from a Kubernetes application. All configuration and any deployment upgrades are covered.
Today we’ll be breaking down what is a Kubernetes operator, understanding them and discovering why they are so important. Let’s deep dive straight in.
Understanding Kubernetes Operator
Firstly, the benefit of using an operator is that you can operate a stateful application through writing a custom controller with domain-specific knowledge built into it. For example, if you have an application that connects to a database you’ll want to deploy it through your Kubernetes cluster. Kubernetes help to act on behalf of the user to perform tasks that your IT team would typically need to perform. Implementing a controller to perform certain tasks can help save valuable time and resources.
Why Are Kubernetes Operators So Important?
1. Operators Increase Kubernetes Functionality
A Kubernetes operator works to extend the power of stateless apps in a way that’s easy and accessible. Operators work to bring the balance back to a wide range of applications. Allowing Kubernetes users to safely deploy and manage their databases without unnecessary obstructions is one of the biggest benefits of Kubernetes operators.
2. Operators Can Review Human Knowledge Like Code
The automation of infrastructure that is needed to run containerized applications is rendered possible through Kubernetes. It can be difficult to translate human knowledge into software. Instead, Kubernetes operators take the knowledge from a DevOps team and systemize it until it is completely automated. One small step for Kubernetes, one huge leap for cloud computing.
3. Operators Increase Resiliency While Reducing The Burden On Your Team
Operators take the pressure off your containers while reducing the burden on your IT team. By simplifying the process, database management including the scale, updates, and management all benefit from the intervention. Without forceful intervention, your IT team has more time to do what it does best without the added stress.
4. Operators Are Useful In Multi-Cloud and Hybrid Environments
Kubernetes operators are extremely useful in multi-cloud and hybrid environments due to their highly distributed nature. Utilizing operators give developers the opportunity to work without necessarily needed domain expertise in a particular infrastructure environment. Creating an application becomes a simplified task rather than a stressor. Moreover, a Kubernetes operator can be used for provisioning multiple applications in a way that is consistent and all the while keeping best practices in mind.
