Hi I have installed and configured kubernates I have tried with both minikube and kubeadm What I have installed: flannel, nginx-ingress-controller, metalLB then setted ngix-ingress-controller service to be loadBalancer
I always get 502 bad gateway when trying to expose a simple wordpress app (using clusterIp or even with nodePort)
OS: ubuntu 20.04 LTS installed docker-ce, kubeadm and kubelt (official kubernates site tutorial)
Installation procedure i have followed: Kube init:
kubeadm init --pod-network-cidr=10.244.0.0/16
kubectl taint nodes --all node-role.kubernetes.io/master-
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
flannel:
kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml
nginx
kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/static/provider/baremetal/deploy.yaml
metallb: followed onsite tutorial
I have tryed to change ingress-nginx-controller service to be LoadBalancer and add the externalIP but nothing changes
