kube-random-hash

NodeJS app that returns a string hash and deploys it in kubernetes pod replicas.

You can inspect your app in Lens Kubernetes IDE:

Steps to execute

If you clone the code start the kube like this:

kubectl apply -f .\manifests\deployment.yaml

Otherwise link directly to this repo:

kubectl apply -f https://raw.githubusercontent.com/quindai/kube-random-hash/main/manifests/deployment.yaml

You should get

deployment.apps/hashgenerator-dep created

Visualize you kube running:

kubectl describe deployment hashgenerator-dep

Extract the NewReplicaSet variable and visualize the pod:

kubectl describe pod hashgenerator-dep-59876bb5fb
...
