Check that your Pods have external IPs with kubectl get pods -o=wide Load Balancing is not supposed to be implemented on your single node machine (with Minikube), there is a somehow a "hack" If you are deploying your cluster on a Cloud provider, Load Balancer would be fully-managed For the "hack" i talk about, look at this tutorial video section on Ingress component explained : [this video] You are expected to place a Pod with a nginx server in front of your ingress, in front of your loadbalancer, in front of your deployment Pods

Recommends MalwareMoon · 2022-11 · Stack Overflow · on “how should i create YAML files for the apps i intend to deploy?”

This is way to broad to give a decent answer for, but to make it short. Mentioned files "deployment.yaml, secret.yaml, pv.yaml, pvc.yaml and service.yam" are not specific to only mysql, it's just what you need to deploy your app on Kubernetes. It's not exactly a entry friendly topic and there is just about no reason to write down entire tutorial just for this post, as there is plenty of sources available, so I will just recommend those that I remember helped me: "you need to learn Kubernetes RIGHT NOW!!" By NetworkChuck [LINK] "Kubernetes Tutorial for Beginners" by TechWorld with Nana [this video] And then there is official documentation: [LINK] I'd also not skip on paying for some test clusters

Hello Mozello, For creating the cluster, it is a simple eksctl command, yes, for MySql I was following: [LINK] for Creating the nodejs deployment I followed this video and tried to get the hang of that, at this time stamp 1:16:16 - Demo Project: MongoDB and MongoExpress [this video] The main difference is that, in the demo she is using NodePort, while in my case I am exposing the cluster using nginx load balancer.

I am running minikube on a Raspberry Pi4. I enabled the ingress with $ minikube addons enable ingress and I created an ingress for the kubernetes-dashboard using this yaml file [LINK] : apiVersion: networking.k8s.io/v1 kind: Ingress metadata: name: dashboard-ingress namespace: kubernetes-dashboard annotations: kubernetes.io/ingress.class: "nginx" spec: rules: - host: dashboard.com http: paths: - path: / pathType: Exact backend: service: name: kubernetes-dashboard port: number: 80 It work fine, creates the ingress and I get this external IP address: 192.168.49.2 . I edited, as suggested in this tutorial [this video] , the /etc/hosts file adding 192.168.49.2 dashboard.com . When I curl dashboard.co

I am new to NATS and kubernetics technologies. I watched the full "TechWorld with Nana" kubernetics tutorial [this video] on YouTube and was able to create the configurations from the video. I have created a NATS service on a minicube from HELM repository as described in the NATS documentation [LINK] . I am able to run it, send and receive a subject, I was also able to configure Jetstream and I was able to receive the saved messages in the subjects via the consumer I created. So far so good, I have a working NATS service, but I can't figure out how to access it from within or outside the cluster. I tried to access it by creating a load balancer, but I noticed that the cluster IP of the NATS servi

I'm relatively new to k8s and was following an tutorial [this video] to get familiar with it. There was a example on exposing kubernetes-dashboard via ingress and I tried to try it. Configured kubernetes-dashboard by running following. As per its documentation [LINK] . kubectl apply -f [LINK] But different from the tutorial kubernetes-dashboard was exposed via port 443 service/dashboard-metrics-scraper ClusterIP 10.108.119.138 <none> 8000/TCP 50m service/kubernetes-dashboard ClusterIP 10.100.58.17 <none> 443/TCP 50m So I changed the ingress configuration yaml accordingly. apiVersion: networking.k8s.io/v1 kind: Ingress metadata: annotations: kubernetes.io/ingress.class: nginx nginx.ingress.kuberne

Cites Probosckie · 2023-04 · Stack Overflow · on “What does Minikube status "control plane" meaning”

I am trying to learn Kubernetes from this YouTube course [this video] . One hands-on thing I am trying is to install Minikube, Docker Desktop and kubectl to see the pods and containers working in real time. I started Minikube - specifying Docker as my VM of choice minikube start --vm-driver=docker As I understand the Minikube will try to run both master and worker node in the same VM. So when I try to get its status like this: minikube status I expected it to give me type as "Master" like what is happening at this point [this video] but it gives "control plane". Even: kubectl get nodes gives "control plane" [LINK] What is "control plane"? It's not mentioned in this page [LINK] .

I am currently working through the following Kubernetes tutorial: [this video] I am using an 2022 Macbook Air with an M2 chip, so Hyperkit is not compatible, so instead I am using Qemu. My problem is this: when I run the external service 'mongo-express-service' with Minikube, the browswer opens, but I am asked to sign in. See 1:44:40 of the video above to see which step I am on. I am using the exact files from Nana's repo, so I think it has something to do with me using Qemu and having to install socket_vmnet to run the external service. This is what I get in the browser when I run the external service. [LINK] This is what I get in my terminal when I run the external service. [LINK] These are my
