Nginx ingress failed: HTTP probe failed with statuscode: 503-CodePudding

I'm following this Link to install nginx-ingress-controller on my bare metal server Kubernetes-v.1.19.6

The below commands i have executed as part of installation.

$ git clone https://github.com/nginxinc/kubernetes-ingress.git --branch v2.4.0
$ cd kubernetes-ingress/deployments

$ kubectl apply -f common/ns-and-sa.yaml
$ kubectl apply -f rbac/rbac.yaml
$ kubectl apply -f rbac/ap-rbac.yaml
$ kubectl apply -f rbac/apdos-rbac.yaml

$ kubectl apply -f common/default-server-secret.yaml
$ kubectl apply -f common/nginx-config.yaml
$ kubectl apply -f common/ingress-class.yaml


$ kubectl apply -f daemon-set/nginx-ingress.yaml

I have followed DaemonSet method.

$ kubectl get all -n nginx-ingress

Still READY and UP-TO-DATE state showing 0, Ideally it show 3 in both the categories. Please let me know what i'm missing here as part of installation?

Any help is appreciated.

CodePudding user response：

can you share the nginx logs?

kubectl -n nginx-ingrelss logs -l app=ginx-ingress

I can't guess anything..

CodePudding user response：

I'd recommend installing it using helm

See https://github.com/nginxinc/kubernetes-ingress/tree/main/deployments/helm-chart

helm repo add nginx-stable https://helm.nginx.com/stable

helm install nginx-ingress nginx-stable/nginx-ingress \
    --namespace $NAMESPACE \
    --version $VERSION

You can look for versions compatibles with your Kubernetes cluster version using:

helm search repo nginx-stable/nginx-ingress --versions

When installation is well finished, you should see ingress-controller service that holds an $EXTERNAL-IP

NAME                                 TYPE           CLUSTER-IP     EXTERNAL-IP      PORT(S)                                  AGE

ingress-nginx-controller             LoadBalancer   10.0.XXX.XXX   XX.XXX.XXX.XX   80:30578/TCP,443:31874/TCP               548d
