Kubernetes (K8S) is an open-source container orchestration tool that can automatically scale, distribute, and handle faults on containers. Originally created by Google and donated to the Cloud Native Computing Foundation, Kubernetes is widely used in production environments to handle Docker containers (although it supports other containers tools such as rkt) in a fault-tolerant manner.

Security should be a top priority for any production system and must be even stricter when securing clusters since they involve more moving parts that need to cooperate with one another. Securing a simple system involves maintaining good practices and updated dependencies, but to secure an environment, whether clustered or not, the operator needs to evaluate the communications, images, operational system, and hardware issues. Data breaches, Denial of Service attacks, stolen sensitive information or simply downtime, can all be avoided with solid security policies.
