You don't have to manipulate people with fear and negativity, he swimming cap insists. "As a head chef you've got to find a better way." Suffice to say, Meiers does not take the Marco Pierre White approach to kitchen bollockings; he also points out that young chefs today are unlikely to tolerate them, either. Instead, if one of his chefs seems flustered and is making mistakes, Meiers will quietly take them aside and talk them through a circular-breathing exercise in order to help them re-centre.

OpenShift has been often called as  Enterprise Kubernetes by its vendor - Red Hat. In this article, I m describing real differences between OpenShift and Kubernetes. It s often confusing, as Red Hat tends to describe it as PaaS, swimming cap for kids sometimes hiding the fact that Kubernetes is an integral part of OpenShift with more features built around it. Let s dive in and check what are the real differences between those two.

Kubernetes is an open source project (or even a framework), swimming cap in walmart while OpenShift is a product that comes in many variants. There s an open source version of OpenShift which is called OKD . Previously it was called OpenShift Origin, but some  clever folks at Red Hat came up with this new name which supposes to mean  The Origin Community Distribution of Kubernetes that powers Red Hat OpenShift (?). But let s forget about names for a while and focus on what are implications of that.

For someone coming straight swimming cap at walmart from Kubernetes world who used Helm and its charts, OpenShift templates as the main method of deployment whole stack of resources is just too simple. Helm charts use sophisticated templates and package versioning that OpenShift templates are missing. It makes deployment harder on OpenShift and in most cases you need some external wrappers (like I do) to make it more flexible and useful in more complex scenarios than just simple, one pod application deployments.

It has some drawbacks, but also one significant advantage over Kubernetes Deployment - you can use hooks to prepare your environment for an update - e.g. by changing database schema. It s a nifty feature that is hard to implement with Deployment (and no, InitContainers are not the same, as it s hard to coordinate it with many instances running). Deployment, however, is better when dealing with multiple, concurrent updates - DeploymentConfig doesn swimming cap at target  t support concurrent updates at all and in Kubernetes you can have many of them and it will manage to scale them properly.

This a minor difference, but on OpenShift there are projects which are nothing more than just Kubernetes namespaces with additional features. Besides trivial things such as description and display name (trust me - they can be helpful when you have dozens of them), projects add some default objects. Currently a few roles ( RoleBinding objects to be precise) are created alongside with a project, but you can modify default project template and use it to provision other objects.
