Kubernetes 101

You can go ahead with its documentation or everything, even straight with chatgpt if you fulfill these:

• You know the fact that pods can run numerous containers
• You know kubernetes can be installed through Docker Desktop or Docker Toolbox (MiniKube) or MicroK8S
• For convenience make sure the kubectl is installed
• If you decide to install through MicroK8s, use snap (rather than apt or yum)
• Read the kubernetes terminologies like Pod, Controller, Service, Namespace, Node, Kubelet, Control Plane
• You have to know the way kubernetes load the docker image.
• You have to know the purpose of dockerhub, and eventually your docker registry url
• If you decide not to push the docker image to private registry, then you make your own registry container
• Make sure you pushed your image to docker registry url: docker tag experimental-service-alpha localhost:5000/experimental-service-alpha -> docker push localhost:5000/experimental-service-alpha
• Your pods at least can have status ContainerCreating, ImagePullBackOff, ErrImagePull, and Running
• Common reason that you have status other than Running is that Kubernetes didnt find the image, you have to push first.

This when you push the image to registry / dockerhub

This feels good
