So, let's say you use Docker, package applications into Docker images, and deploy to production. This works if you have a simple application and you are delighted with how it works. But this is not enough if the requirements for your applications are higher than usual.
For example:
- Fault tolerance.
- Resource limits.
- Scalability.
- Combining applications into groups.
- Collecting metrics and logs.
- Security and access control.
- Simple integration with different solutions.
- Launching applications on a schedule.
Among all options suitable to solve this tasks, Kubernetes stays the best choice.

Kubernetes also have some useful components such as DNS for Services and Pods, Cluster level log, The package manager- Helm that ease and make the work with Kubernetes more interesting.
