Helm Test

The only advice I can give to folks who are building helm charts from scratch, is always keep it incremental and do not try to do everything at one go. At least build a decent few before you even try to attempt such a thing, else you will only end up WASTING your precious time on trivial issues which could have been avoided by incremental build, rather than the big bang approach.

K8S: Deployment

Time to re-test how to create deployments. It has been sometime, I created some deployments so just checking on how much I remember.

The quick way to always get started is to check the HELP.

Services: K8S

There are multiple Kubernetes objects we will be talking about in this blog. Mainly Services, Selectors and Labels.

Service is an abstraction which defines a logical set of Pods and a policy by which to access them.
A Service in Kubernetes is a REST object, similar to a Pod.
Service tags the pods, logically grouping them using selectors.
Pods have a lifecycle, they are born, they live, process and then they die. The pods (desired state) can be managed using deployment.
A label is an identifying attribute of an object, and can be defined at the creation time, and subsequently modified and added at any time.
Label selector is a grouping primitive in Kubernetes and allows client/user to identify a set of objects. There are two sets of selectors
- equality-based and
- set-based.

An abstract way to expose an application running on a set of Pods as a network service.

The set of Pods targeted by a Service is usually determined by a selector.
