Kubernetes has lots of concepts. It’s easy to get lost in the middle of all core concept the project has. However, all these abstractions provide a great benefit which is the standard spec for different kinds of services and workloads. IF cloud providers were born with a common spec/API, we would not be talking about this subject now a day, unfortunately, this is not the reality. Today I want to share a simple presentation I made trying to explain the many concepts present in kubernetes and how they differentiate between each other like what’s the difference of a Secret vs ConfigMap or how ReplicateSet is different compared with a Deployment. Also, cover what kinds of service are available and when to use ClusterIP vs Loadbalancer for instance. You will also see GitOps model, which the standard k8s way to work in production.
