# Nginx Ingress DaemonSet
|
|
|
|
In some cases, the Ingress controller will be required to be run at all the nodes in cluster. Using [DaemonSet](https://github.com/kubernetes/community/blob/master/contributors/design-proposals/daemon.md) can achieve this requirement.
|
|
|
|
## Default Backend
|
|
|
|
The default backend is a service of handling all url paths and hosts the nginx controller doesn't understand. Deploy the default-http-backend as follow:
|
|
|
|
```console
|
|
$ kubectl apply -f ../../deployment/nginx/default-backend.yaml
|
|
deployment "default-http-backend" configured
|
|
service "default-http-backend" configured
|
|
|
|
$ kubectl -n kube-system get svc
|
|
NAME CLUSTER-IP EXTERNAL-IP PORT(S) AGE
|
|
default-http-backend 192.168.3.6 <none> 80/TCP 1h
|
|
|
|
$ kubectl -n kube-system get po
|
|
NAME READY STATUS RESTARTS AGE
|
|
default-http-backend-2657704409-6b47n 1/1 Running 0 1h
|
|
```
|
|
|
|
## Ingress DaemonSet
|
|
|
|
Deploy the daemonset as follows:
|
|
|
|
```console
|
|
$ kubectl apply -f nginx-ingress-daemonset.yaml
|
|
daemonset "nginx-ingress-lb" created
|
|
|
|
$ kubectl -n kube-system get ds
|
|
NAME DESIRED CURRENT READY NODE-SELECTOR AGE
|
|
nginx-ingress-lb 2 2 2 <none> 21s
|
|
|
|
$ kubectl -n kube-system get po
|
|
NAME READY STATUS RESTARTS AGE
|
|
default-http-backend-2657704409-6b47n 1/1 Running 0 2h
|
|
nginx-ingress-lb-8381i 1/1 Running 0 56s
|
|
nginx-ingress-lb-h54gf 1/1 Running 0 56s
|
|
```
