Kubernetes for Developers #8: Kubernetes Object Name, Labels, Selectors and Namespace

Object Name Every Kubernetes object has a Name that is unique for that type of resource within the same namespace. It means, we can only have one Pod name called “ mynginx ” within the same namespace. however, we can use same name for another Kubernetes object like Deployment, Service, etc. So, we can set same name i.e., “ mynginx ” to Pod, Deployment, Service, etc. The following characteristics need to be followed while setting name to Kubernetes object. Name should not exceed 253 characters It contains only lowercase alphanumeric characters (a to z), hyphen (-), period(.) It should start with an alphanumeric character It should end with an alphanumeric character apiVersion : v1 kind : Pod metadata : name : mynginx spec : Labels Label is a key-value pair which is attached to pods, deployments, etc. It acts an identifier on K8 object (Ex: Pod or Deployment).

Secret and configuration management : It maintains an application level configuration and secrets in a separate location. So, it can be modified without re-building and deploying container 3. Horizontal scaling: It is easy to scale-up/down containers with a simple command or automatically based on CPU usage. 4. Automatic bin packing: It automatically places containers into the required Worker nodes based on specified CPU/Memory. 5. Storage orchestration : It allows to mount a local storage or cloud providers 6.

Kubernetes for Developers #14: Kubernetes Deployment YAML manifest in-detail

In previous articles, we have learned how to create or manage Pod manually. However, in real-world use cases, The Pod creation/re-creation should be done automatically and remain healthy without manual intervention, that’s where K8 Deployment comes into the picture. It helps us to manage set of identical pods without creating/updating/deleting pods manually. It makes desired number of identical pods always stay up and running automatically without user intervention. It is a high-level resource, the actual pods are created and managed by the ReplicaSets, not by the Deployment directly. ReplicaSet constantly monitors the list of running pods and makes sure the actual number of pods are always matching the desired number of pods. It there are only few pods are running, it creates new replicas from a pod template. If there are many pods are running than desired number, it removes the excess replicas. Deployment YAML file contains both desired replica count and Pod template in it. Therefor...
