You don't have to manipulate people with swim goggles fear and negativity, he 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.
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 best swim goggles for kids 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 kids swimming goggles Kubernetes that powers Red Hat OpenShift (?). But let s forget about names for a while and focus on what are implications of that.
Also, RBAC was an integral part of OpenShift since many releases while there are some people who use Kubernetes without RBAC security. That s okay for a small dev/test setup, but in real life, you want to have some level of permissions - even if it s sometimes amazon swimming goggles hard to learn and comprehend (because it is at first). In OpenShift you actually don t have a choice and you have to use it and learn it on the way as you deploy more and more apps on it.
Helm 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 Kubernetes however you can use different enhancements - my favorite one is an integration with cert-manager that allows you to automate management speedo swimming goggles 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 logic based on dedicated pods controlling whole process.
