Kubernetes has a large, active community and strong industry support, which means abundant resources, tutorials, and third-party integrations are available.

Possible disadvantages of Kubernetes

Complexity
The learning curve associated with Kubernetes is steep due to its numerous components, configurations, and operational paradigms.
Resource Intensive
Running a Kubernetes cluster can be resource-intensive, often requiring significant CPU, memory, and storage resources, which can be costly.
Operational Challenges
Managing a Kubernetes cluster requires expertise in areas such as networking, security, and cluster lifecycle management, making it challenging for smaller teams or organizations.
Debugging and Troubleshooting
Pinpointing issues within a Kubernetes cluster can be difficult due to its distributed and dynamic nature, which can complicate debugging and troubleshooting processes.
Configuration Overhead
Kubernetes involves numerous configurations and settings, which can be overwhelming and error-prone, especially during initial setup and deployment.
