Kubernetes Quotes

That idea of the state as a ship and its ruler as the helmsman or captain is a very old one in European culture. It is frequently used by Cicero, and indeed our word ‘governor’ comes from the Latin for ‘helmsman’ – gubernator. Even more enticingly, the root of gubernator is the Greek kubernetes, which is also the origin of our word ‘cybernetics’; so the notions of ruling, steering and robotics all coincide in our language – and in this galleon.

Unfortunately, as with a lot of revolutionary technology, Magnum isn’t always available, and supported orchestration engines like swarm, Mesos, and Kubernetes could still use some time to mature and stabilize

For example, the ability to shift gears from Kubernetes to Swarm without having to modify your deployment system could be a huge win, and while virtual machines are likely to be a big part of the landscape for many years to come, containers are here to stay

Lastly, there are new companies, such as Rancher Labs and projects like Kubernetes and Mesos, that are starting to provide container-focused orchestration solutions that live on top of, or work with, OpenStack. These are the bleeding edge of virtualization technology and as such are likely to see huge changes before mainstream adoption

Discussions around architecture often focus on tools and technologies. Should the organization adopt microservices or serverless architectures? Should they use Kubernetes or Mesos? Which CI server, language, or framework should they standardize on? Our research shows that these are wrong questions to focus on. What tools or technologies you use is irrelevant if the people who must use them hate using them, or if they don’t achieve the outcomes and enable the behaviors we care about. What is important is enabling teams to make changes to their products or services without depending on other teams or systems. Architects should collaborate closely with their users—the engineers who build and operate the systems through which the organization achieves its mission—to help them achieve better outcomes and provide them the tools and technologies that will enable these outcomes.

rolling updates that give you the predefined number of limited pods and the spare pods that exist temporarily; and canary deployments that ensure that you simultaneously upgrade from the older version to the newer version.

Microservice infrastructure in these containers makes it easy for you to split your application into small components and run them in different environments and clouds. Kubernetes does not limit you and can be used anywhere—in public, private, or other hybrid clouds. This functionality enables you to reach out to users wherever they are, and makes it more secure. Many of today's businesses have grown to love and use this microservice, since it makes their tools more easily manageable. 7.

A classe ​ ​Item​ ​ é um pouco diferente. Nela, utilizamos a anotação ​ ​@Embeddable​ ​, indicando que ela pode ser embutida em uma entidade. Uma classe com a anotação ​ ​@Embeddable​ ​ não tem vida própria, ela sempre depende de uma entidade, isto é, de uma classe que tenha a anotação ​ ​@Entity​

A partir de um Deployment, o Kubernetes cria um ou mais ​ ​Pods​ ​, que são como instâncias de um ​ ​Deployment​ ​. O ​ ​Pod​ ​ é a máquina rodando no cluster e contém um ou mais contêineres sendo executados, um IP real dentro do cluster, espaço para armazenamento e utiliza recursos da máquina. Normalmente, quando criamos um ​ ​Deployment​ ​, automaticamente o Kubernetes já cria também um respectivo ​ ​Pod​

(C)ybernetics, the science of computers, comes from the Greek kubernetes, "helmsman" or "governor," meaning simply that the machine is in charge.

Kubernetes never kills pods just because the cluster administrator wants their disk space back.
