You can use this information to quickly remediate security issues and improve the security of your containers. These components can be divided into two categories: nodes: Each Kubernetes cluster requires at least one worker node, which is a collection of worker machines that make up the nodes where our container will be deployed. Recently, Kubernetes was in the news for all the wrong reasons: security flaws. It groups containers that make up an application into logical units for easy management and discovery. Kubernetes Introduction. For now, think of pods as groups of microservices (containers) that are so tightly related they cannot be deployed separately. Me: I want 3 healthy instances of redis to always be running. Kubernetes: Okay, Ill ensure there are always 3 instances up and running. Kubernetes: Oh look, one has died. Register now. Bring innovation anywhere to your hybrid environment across on-premises, multicloud, and the edge. 0 0 2,729. d.) Docker Docker is the containerization platform that is used to package your application and all its dependencies together in the form of containers to make sure that your application works seamlessly in any environment which can be development or test or production.
