# HAProxy Ingress rewrite
|
|
|
|
This example demonstrates how to use rewrite options on HAProxy Ingress controller.
|
|
|
|
## Prerequisites
|
|
|
|
This document has the following prerequisites:
|
|
|
|
* Deploy [HAProxy Ingress](/examples/deployment/haproxy) controller, you should
|
|
end up with controller, a sample web app and an ingress resource named `app` to
|
|
the `foo.bar` domain
|
|
* Configure only the default [TLS termination](/examples/tls-termination/haproxy) -
|
|
there is no need to create another secret
|
|
|
|
As mentioned in the deployment instructions, you MUST turn down any existing
|
|
ingress controllers before running HAProxy Ingress.
|
|
|
|
## Annotations
|
|
|
|
The following annotations are implemented:
|
|
|
|
* `ingress.kubernetes.io/ssl-redirect`: Indicates whether a redirect should be
|
|
done from HTTP to HTTPS. Possible values are `"true"` to redirect to HTTPS,
|
|
or `"false"` meaning requests may be performed as plain HTTP.
|
|
* `ingress.kubernetes.io/app-root`: Defines the URL to be redirected when requests
|
|
are done to the root context `/`.
|
|
|
|
### SSL Redirect
|
|
|
|
Annotate the `app` ingress resource:
|
|
|
|
```console
|
|
$ kubectl annotate ingress/app --overwrite ingress.kubernetes.io/ssl-redirect=false
|
|
ingress "app" annotated
|
|
```
|
|
|
|
Try a HTTP request:
|
|
|
|
```console
|
|
$ curl -iL 172.17.4.99:30876 -H 'Host: foo.bar'
|
|
HTTP/1.1 200 OK
|
|
Server: nginx/1.9.11
|
|
Date: Sat, 15 Apr 2017 19:27:30 GMT
|
|
Content-Type: text/plain
|
|
Transfer-Encoding: chunked
|
|
|
|
CLIENT VALUES:
|
|
client_address=10.2.33.14
|
|
command=GET
|
|
real path=/
|
|
query=nil
|
|
...
|
|
```
|
|
|
|
Now turn ssl-redirect true:
|
|
|
|
```console
|
|
$ kubectl annotate ingress/app --overwrite ingress.kubernetes.io/ssl-redirect=true
|
|
ingress "app" annotated
|
|
|
|
$ curl -iL 172.17.4.99:30876 -H 'Host: foo.bar'
|
|
HTTP/1.1 302 Found
|
|
Cache-Control: no-cache
|
|
Content-length: 0
|
|
Location: https://foo.bar/
|
|
|
|
...
|
|
```
|
|
|
|
The default value of ssl-redirect annotation is true and can be changed globally
|
|
using a [ConfigMap](https://github.com/jcmoraisjr/haproxy-ingress#configmap).
|
|
|
|
### App root context redirect
|
|
|
|
Annotate the `app` ingress resource with `app-root`, and also `ssl-redirect` to `false` for simplicity:
|
|
|
|
```console
|
|
$ kubectl annotate ingress/app --overwrite ingress.kubernetes.io/app-root=/web
|
|
ingress "app" annotated
|
|
|
|
$ kubectl annotate ingress/app --overwrite ingress.kubernetes.io/ssl-redirect=false
|
|
ingress "app" annotated
|
|
```
|
|
|
|
Try a HTTP request:
|
|
|
|
```console
|
|
$ curl -iL 172.17.4.99:30876 -H 'Host: foo.bar'
|
|
HTTP/1.1 302 Found
|
|
Cache-Control: no-cache
|
|
Content-length: 0
|
|
Location: /web
|
|
|
|
HTTP/1.1 200 OK
|
|
Server: nginx/1.9.11
|
|
Date: Sat, 15 Apr 2017 19:34:49 GMT
|
|
Content-Type: text/plain
|
|
Transfer-Encoding: chunked
|
|
|
|
CLIENT VALUES:
|
|
client_address=10.2.33.14
|
|
command=GET
|
|
real path=/web
|
|
query=nil
|
|
...
|
|
```
