Kubernetes version: v1.19.4
Cloud being used: (put bare-metal if not on a public cloud) bare-metal
Installation method: kubeadm
Host OS: CentOS 7.5 (64-bit)
CNI and version: Docker version 19.03.13
CRI and version: 3.14
I am relatively new to Kubernetes. I have deployed K8s cluster on-premises. Locally I am able to access my application UI through node port service using my worker node IP.
I am using NGINX ingress controller. I deployed haproxy as a external load balancer outside my K8s cluster.
Following are the entries for worker nodes in ha proxy config file
frontend main bind *:7979 option tcplog default_backend http backend http balance roundrobin server workernode1 10.221.86.37:32210 check server workernode2 10.221.86.38:32210 check server workernode3 10.221.86.39:32210 check
Following are details for NGINX ingress controller
NAME READY STATUS RESTARTS AGE pod/nginx-ingress-4q9w8 1/1 Running 0 2d7h pod/nginx-ingress-55fw4 1/1 Running 0 2d7h pod/nginx-ingress-cp8sj 1/1 Running 0 2d7h NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE service/nginx-ingress NodePort 10.99.249.144 <none> 80:32210/TCP,443:31078/TCP 2d7h NAME DESIRED CURRENT READY UP-TO-DATE AVAILABLE NODE SELECTOR AGE daemonset.apps/nginx-ingress 3 3 3 3 3 <none> 2d7h
I have refer beneath official documentation to install ingress controller as daemonset.
Note: All cluster resources including ingress controller are in “default” namespace. I used apiVersion “networking.k8s.io/v1” for Ingress.
When I try to access the haproxy url, I can see below controller log:-
“[error] 39#39: 28 broken header: "GET / HTTP/1.1
User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/87.0.4280.88 Safari/537.36
Accept-Encoding: gzip, deflate
while reading PROXY protocol, client: 192.168.216.64, server: 0.0.0.0:80”
And over the browser I get “ 502 Bad Gateway The server returned an invalid or incomplete response “
Can anybody suggest and give some clues to resolve above said issues ??
If any further details are required, please let me know.
Thanks in advance
