Kubernetes is a container orchestration platform. Often abbreviated “k8s” (for some reason). It’s now the predominant platform for orchestrating clusters of containers. Originally built on top of Docker#, Kubernetes is generally Linux specific and runs on top of at least one Linux server in most configuration.

It’s main interface is through yaml files and the primary means of configuring it is through the kubectl command line utility.

Several other “distributions” of kubernetes exist, such as RedHat’s OpenShift, which aims to enhance and reimplement portions of the kubernetes ecosystem aimed primarily at enterprise use.

Disable a CronJob
