It s often confusing, as Red Hat tends to describe it White Adidas Hat as PaaS, 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), 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.

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. Helm Adidas Golf Hat is so much better , but its current architecture (Tiller component installed as Pod with huge permissions) isn t compatible with more strict security polices in OpenShift.So which one is better you may ask? Personally, I think HAproxy in OpenShift is much more mature, although doesn t have as much features as some Ingress implementations. On Adidas Denim Hat Kubernetes however you can use different enhancements - my favorite one is an integration with cert-manager that allows you to automate management of SSL certificates.

No more manual actions for issuing and renewal of certificates and additionally you can use trusted CA for free thanks to integration with Letsencrypt !Similarly like with Ingress, OpenShift chose to have a different way of managing deployments. In Kubernetes there are Deployment objects (you can also use them in OpenShift with all other Kubernetes objects as well) responsible for updating pods in a rolling update fashion and is implemented internally in controllers. OpenShift has a similar object called DeploymentConfig implemented not by controllers, but rather by sophisticated Black Adidas Hat logic based on dedicated pods controlling whole process.

There are multiple CI/CD software solutions available, but Jenkins is still the biggest, most universal, generic and mature solution. It is also often used with Kubernetes clusters to build container images, perform Continuous Integration tasks on them and deploy them as containers on multiple environments with Continuous Deployment pipelines. Since it s so popular then having it as a builtin part of OpenShift makes the whole CI/CD a lot less painful. Here s a list of my favorite features of integrated Jenkins on OpenShift: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. A good example would be network policies that close your project for external traffic so that is isolated and secure by default - if you want to permit some kind of traffic you would do so by creating additional policies explicitly. In a similar way you could provide default quotas or LimitRange objects and make your new projects pre-configured according to your organization rules.

Our new acquaintance very deliberately Pink Adidas Hat coiled up the tube of his hookah , and produced from behind a curtain a very long, befrogged top-coat with astrakhan collar and cuffs. This he buttoned tightly up, in spite of the extreme closeness of the night, and finished his attire by putting on a rabbit-skin cap with hanging lappets which covered the ears, so that no part of him was visible save his mobile and peaky face. "My health is somewhat fragile," he remarked, as he led the way down the passage. "I am compelled to be a valetudinarian."Well, he has the name of being a dangerous man.
