0.27.0

Image: quay.io/kubernetes-ingress-controller/nginx-ingress-controller:0.27.0

New Features:

NGINX 1.17.7
Migration to alpinelinux.
Global Modsecurity Snippet via ConfigMap
Support Datadog sample rate with global trace sampling from configmap #4897
Modsecurity CRS v3.2.0 #4829
Modsecurity-nginx v1.0.1 #4842
Allow enabling/disabling opentracing for ingresses #4732

Breaking Changes:

Enable download of GeoLite2 databases #4896

From maxmind website:
```
Due to upcoming data privacy regulations, we are making significant changes to how you access free GeoLite2 databases starting December 30, 2019.
Learn more on our blog https://blog.maxmind.com/2019/12/18/significant-changes-to-accessing-and-using-geolite2-databases/
```
Because of this change, it is not clear we can provide the databases directly from the docker image. To enable the feature, we provide two options:
- Add the flag --maxmind-license-key to download the databases when the ingress controller starts.
- or add a volume to mount the files GeoLite2-City.mmdb and GeoLite2-ASN.mmdb in the directory /etc/nginx/geoip.
If any of these conditions are not met, the geoip2 module will be disabled
The feature lua-resty-waf was removed.
Due to the migration to alpinelinux the uid of the user is different. Please make sure to update it runAsUser: 101 or the ingress controller will not start (CrashLoopBackOff).

Changes:

#4617 Fix ports collision when hostNetwork=true
#4619 Fix issue #4244

0.26.0

Image: quay.io/kubernetes-ingress-controller/nginx-ingress-controller:0.26.0

New Features:

Add support for NGINX proxy_ssl_* directives
Add support for FastCGI backends
Only support SSL dynamic mode
Add nginx ssl_early_data option support
Add support for multiple alias and remove duplication of SSL certificates
Support configuring basic auth credentials as a map of user/password hashes
Caching support for external authentication annotation with new annotations auth-cache-key and auth-cache-duration
Allow Requests to be Mirrored to different backends #4379
Improve connection draining when ingress controller pod is deleted using a lifecycle hook:

With this new hook, we increased the default terminationGracePeriodSeconds from 30 seconds to 300, allowing the draining of connections up to five minutes.

If the active connections end before that, the pod will terminate gracefully at that time.

To efectively take advantage of this feature, the Configmap feature worker-shutdown-timeout new value is 240s instead of 10s.

IMPORTANT: this value has a side effect during reloads, consuming more memory until the old NGINX workers are replaced.
```
lifecycle:
  preStop:
    exec:
      command:
        - /wait-shutdown
```
mimalloc as a drop-in replacement for malloc.

This feature can be enabled using the LD_PRELOAD environment variable in the ingress controller deployment

Example:
```
env:
- name: LD_PRELOAD
  value: /usr/local/lib/libmimalloc.so
```
Please check the additional options it provides.

Breaking Changes:

The variable $the_real_ip variable was removed from template and default log_format.
The default value of configmap setting proxy-add-original-uri-header is now "false".

When the setting proxy-add-original-uri-header is "true", the ingress controller adds a new header X-Original-Uri with the value of NGINX variable $request_uri.

In most of the cases this is not an issue but with request with long URLs it could lead to unexpected errors in the application defined in the Ingress serviceName, like issue 4593 - 431 Request Header Fields Too Large

Non-functional improvements:

Removal of internal NGINX unix sockets
Automation of NGINX image using terraform scripts

Removal of Go profiling on port :10254 to use localhost:10245

To profile the ingress controller Go binary, use:

INGRESS_PODS=($(kubectl get pods -n ingress-nginx -l app.kubernetes.io/name=ingress-nginx -o 'jsonpath={..metadata.name}'))
kubectl port-forward -n ingress-nginx pod/${INGRESS_PODS[0]} 10245

Using the URL http://localhost:10245/debug/pprof/ to reach the profiler.

NGINX 1.15.9
New canary-by-header-value annotation.

Breaking changes:

The NGINX server listening in port 18080 was removed. It was replaced by a server using an unix socket as port #3684 This server was internal to the ingress controller. In case this was being acceded from the outside, you can restore the old server using the http-snipet feature in the configuration configmap like:
```
http-snippet: |
  server {
    listen 18080;

    location /nginx_status {
      allow 127.0.0.1;
      allow ::1;
      deny all;
      stub_status on;
    }

    location / {
      return 404;
    }
  }
```

Changes:

Fix regression with ingress.class annotation introduced in 0.9-beta.18

0.9-beta.18

Image: quay.io/kubernetes-ingress-controller/nginx-ingress-controller:0.9.0-beta.18

Breaking changes:

The NGINX ingress annotations contains a new prefix: nginx.ingress.kubernetes.io. This change is behind a flag to avoid breaking running deployments. To avoid breaking a running NGINX ingress controller add the flag --annotations-prefix=ingress.kubernetes.io to the nginx ingress controller deployment. There is one exception, the annotation kubernetes.io/ingress.class remains unchanged (this annotation is used in multiple ingress controllers)
