KUBERNETES
Kubernetes is an open-source system for automating the deployment, scaling, and management of containerized applications. It groups containers that make up an application into logical units for easy management and discovery. Kubernetes is widely used for managing microservices architectures and ensuring high availability and scalability.
What is KUBERNETES
Kubernetes, often abbreviated as K8s, is an open-source platform designed to automate the deployment, scaling, and operation of application containers. Originally developed by Google, Kubernetes is now maintained by the Cloud Native Computing Foundation (CNCF). It provides a framework to run distributed systems resiliently, taking care of scaling and failover for applications, providing deployment patterns, and more.
Kubernetes allows developers to manage containerized applications across multiple hosts, offering features such as automated rollouts and rollbacks, service discovery, load balancing, storage orchestration, and self-healing. It is particularly useful in microservices architectures where applications are broken down into smaller, loosely coupled services that can be developed, deployed, and scaled independently.
The platform has become the de facto standard for container orchestration, supported by a large and active community. It integrates with various cloud providers and on-premises environments, making it a versatile choice for organizations looking to modernize their application infrastructure. Kubernetes also supports a wide range of tools and extensions, enhancing its functionality and adaptability to different use cases.
Security risk
If port 2380 is open and the Kubernetes service is running, it could be a target for unauthorized access or attacks. Exposing this port without proper security measures can lead to potential breaches, data leaks, or unauthorized control over the containerized applications. It is crucial to secure this port with appropriate firewall rules and authentication mechanisms.
In our UFW tutorial you can follow instructions how you can configure UFW to close port 2379. Use StackChanges to monitor if the KUBERNETES port is closed and stays closed. StackChanges will send an alert if port 2379 is open again.
