-# HAProxy Ingress TLS termination
-
-## Prerequisites
-
-This document has the following prerequisites:
-
-* Deploy [HAProxy Ingress controller](/examples/deployment/haproxy), you should end up with controller, a sample web app and default TLS secret
-* Create [*another* secret](/examples/PREREQUISITES.md#tls-certificates) named `foobar-ssl` and subject `'/CN=foo.bar'`
-
-## Using default TLS certificate
-
-Update ingress resource in order to add TLS termination to host `foo.bar`:
-
-```console
-$ kubectl replace -f ingress-tls-default.yaml
-```
-
-The difference from the starting ingress resource:
-
-```console
- metadata:
-   name: app
- spec:
-+  tls:
-+  - hosts:
-+    - foo.bar
-   rules:
-   - host: foo.bar
-     http:
-```
-
-Trying default backend:
-
-```console
-$ curl -iL 172.17.4.99:30876            
-HTTP/1.1 404 Not Found
-Date: Tue, 07 Feb 2017 00:06:07 GMT
-Content-Length: 21
-Content-Type: text/plain; charset=utf-8
-
-default backend - 404
-```
-
-Now telling the controller we are `foo.bar`:
-
-```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: https://foo.bar/
-Connection: close
-^C
-```
-
-Note the `Location` header - this would redirect us to the correct server.
-
-Checking the default certificate - change below `31692` to the TLS port:
-
-```console
-$ openssl s_client -connect 172.17.4.99:31692
-...
-subject=/CN=localhost
-issuer=/CN=localhost
----
-```
-
-... and `foo.bar` certificate:
-
-```console
-$ openssl s_client -connect 172.17.4.99:31692 -servername foo.bar
-...
-subject=/CN=localhost
-issuer=/CN=localhost
----
-```
-
-## Using a new TLS certificate
-
-Now let's reference the new certificate to our domain. Note that secret
-`foobar-ssl` should be created as described in the [prerequisites](#prerequisites)
-
-```console
-$ kubectl replace -f ingress-tls-foobar.yaml 
-```
-
-Here is the difference:
-
-```console
-   tls:
-   - hosts:
-     - foo.bar
-+    secretName: foobar-ssl
-   rules:
-   - host: foo.bar
-     http:
-```
-
-Now `foo.bar` certificate should be used to terminate TLS:
-
-```console
-$ openssl s_client -connect 172.17.4.99:31692
-...
-subject=/CN=localhost
-issuer=/CN=localhost
----
-
-$ openssl s_client -connect 172.17.4.99:31692 -servername foo.bar
-...
-subject=/CN=foo.bar
-issuer=/CN=foo.bar
----
-```
