Can Kubernetes run without Docker?
Can Kubernetes Run Without Docker? The answer is both yes and no. Kubernetes, in itself, is not a complete solution. It depends on a container runtime to orchestrate; you can't manage containers without having containers in the first place.
What is the difference between Kubernetes and containers?
While the promise of containers is to code once and run anywhere, Kubernetes provides the potential to orchestrate and manage all your container resources from a single control plane. It helps with networking, load-balancing, security, and scaling across all Kubernetes nodes which runs your containers.
How does Kubernetes work?
Among different possibilities, Kubernetes simplifies some specific deployment tasks that are particularly valuable for modern application developers. These comprise of the following: 1 In horizontal autoscaling, Kubernetes auto scalers automatically scale the number of pods in a deployment based on the application of specific resources. 2 Updates to a Kubernetes distribution are designed “seamlessly” in the distribution’s pods. These updates work with voluntary default limits on the number of pods that may not be available and the number of spare pods that may temporarily exist. 3 In Canary distributions, a helpful model when deploying a new variant of distribution is to test the new deployment and then scale it up by overcoming the old one.
Why is Kubernetes important for DevOps?
Kubernetes indicates an invention for DevOps as it lets teams keep pace with the modern software development needs. In its absence, teams get pushed to produce their software deployment, scaling, and update workflows. Some organizations employ large groups to handle these tasks on their own.

Red Hat Marketplace delivers software for Kubernetes automation
Extend the functionality of all Red Hat ® OpenShift ® platform components with Kubernetes Operators, a method of packaging, deploying, and managing Kubernetes-native applications.
1 Reduce complexity
Traditional application deployment is complex, time consuming, and repetitive. Installing, updating, securing, backing up, and restoring each individual application, infrastructure software, and workload takes tremendous effort.
2 Improve consistency
Because a Kubernetes Operator has the expertise of the developer who wrote the code embedded into the software, the reliance on and importance of institutional knowledge is removed from the equation.
3 Automate at the level you need
The sophistication of the level of management logic built into a Kubernetes Operator can vary, which provides a wide range of choice for the user. To make the level of capabilities readily evident to the user, a Kubernetes Operator maturity model has defined the five phases of maturity for general operations.
4 Achieve compatibility
Eliminate uncertainty about interoperability and performance between Kubernetes Operators and the container platform by relying on Kubernetes Operators, certified by Red Hat. Certified Kubernetes Operators, available on Red Hat Marketplace, are continuously tested on new releases of Red Hat OpenShift to identify upgrade issues.
Why is Kubernetes so powerful?
Kubernetes is a very powerful DevOps tool whose power can be used effectively to remove many of the pain points of deployments and maintenance of code. Additionally, its self-healing nature means the amount of human intervention needed (and potential human error introduced) is greatly reduced. All of this ensures that developers are spending their time writing or improving code, instead of babysitting deployments or being part of lengthy after-hours calls.
How does Kubernetes work?
One final thing I am going to touch on is the self-healing nature of Kubernetes. As I mentioned above, Kubernetes works based on the concept of a desired state. It then compares its current state to the desired state, and makes corrections based on that comparison. For example, if the desired state is two pods, and there’s only one, it will start another pod. This is extremely powerful.
