I walked through the code in a 3 node K8 cluster and doesn't seem like I am able to block the flow of traffic using networkpolicy on a deployment pod. Here is the the output from the exercise. user@myk8master:~$ kubectl…
I want a deployment in kubernetes to have the permission to restart itself, from within the cluster. I know I can create a serviceaccount and bind it to the pod, but I'm missing the name of the most specific permission…
I recently noticed a big accumulation of pods with status 'Shutdown'. We have been using Kubernetes since October, 2020. Production and staging is running on the same nodes except that staging uses preemtible nodes to cut the cost. The containers…
I have a very simple docker-compose app with nginx and php-fpm services. I would like to create a Helm chart that would deploy this exact same thing as a unit (a POD I guess?) but I would like to be…
I install a 3 node Kubernetes Cluster with RKE tool. The installation was successful with no errors but I'm unable to ping from one pod to another pod. If I ping a pod running on worker2 node(NODE-IP-10.222.22.47) I get a…
I installed Kubernetes ingress controller on GKE following the official documentation as following. kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v0.46.0/deploy/static/provider/cloud/deploy.yaml The ingress controller runs fine. ingress-nginx-admission-create-dvkgp 0/1 Completed 0 5h29m ingress-nginx-admission-patch-58l4z 0/1 Completed 1 5h29m ingress-nginx-controller-65d7564f46-2rtjs 1/1 Running 0 5h29m It creates a…
We are have enabled horizontal pod autoscaling in GKE, our pods are sitting behind a clusterIP type service and we are routing public traffic to that Service using NGINX Ingress controller. When monitoring the usages we have noticed that traffic…
I deployed a simple test ingress and an externalName service using kustomize. The deployment works and I get the expected results, but when describing the test-ingress it shows the error: <error: endpoints "test-external-service" not found>. It seems like a k8s…
We've encountered an issue with our deployment on Kubernetes being run on GKE, recently. It would seem that, randomly, our NGINX front end containers, that serve our Front End application, seemingly die. This has caused quite the commotion, as nginx-ingress…
In our project, which also uses Kustomize, our base deployment.yaml file looks like this: apiVersion: apps/v1 kind: Deployment metadata: name: nginx-deployment labels: app: nginx spec: replicas: 3 selector: matchLabels: app: nginx template: metadata: labels: app: nginx spec: containers: - name:…
