Kubernetes Pods, ReplicaSets, and Deployments in 5 Minutes

When should you use a Kubernetes Pod, ReplicaSet or Deployment? In this 5 minute video, learn about basic Kubernetes components and the K8s control loop, along with real Kubernetes configuration YAML. Although pods are the smallest deployable unit of computing within Kubernetes, they are not usually deployed by themselves. Instead, Deployments are a higher-level abstraction used to manage Pods and ReplicaSets. Kubernetes uses a controller model to handle these resources.

This is the most straightforward k8s deployment explanation video on the internet

[@darimco3660]

Thank you so much! That's perfect explanation.

[@monicasaini1307]

thankyou quick and crisp

[@pardiumdhankhar]

it looks like in pod manifest that you write spec field inside metadata so to made it clear whoever saw this spec section remains outside of metadata section or field

[@stephanemenkam]

Good explanations....🤝

Great videos! Starting to explore Kubernetes and EKS so I appreciate all the work done here. I have a question regarding the process of the control loop. When changing the version of an app does Kubernetes role the updates out slowly like an auto scaling refresh replacing a few at a time until all are healthy, does it tear down and replace them all at once, or some is this customizable in config?

[@ContainersfromtheCouch]

Thanks! Kubernetes will do a rolling update ensuring that at least 75% of the desired pods are running. This is customizable.

Congratulations for your presentation skills! Very good on content and style! Just out of curiosity, what tools do you use to do these video effects? Thank you very much for all these great presentations!

[@anand4987]

is that yaml?

[@globalworldino8570]

where can I find the configs? can you make a link for them?

[@ContainersfromtheCouch]

You can find similar deployment configs in the Kubernetes docs: kubernetes.io/docs/concepts/workloads/controllers/deployment/
