+title: 'Updates to Ingress Nginx with network v1'
+date: 2021-05-30
+slug: update-with-ingress-nginx
+---

+**Authors:** James Strong, Richardo Katz 
+
+With all Kubernetes APIs, there is a process to creating, maintaining, and
+ultimately deprecating them once they become GA. The network API is no
+different. With the release of Kubernetes 1.22, the network API goes from
+v1beta1 to v1, with v1beta is deprecated. This move has been in discussion
+for quite some time now in 2017 in
+[issue #43214](https://github.com/kubernetes/kubernetes/issues/43214),
+[2019 with 1.16 api deprecation](https://kubernetes.io/blog/2019/07/18/api-deprecations-in-1-16/)
+, and more recently in
+[KEP-1453:Graduate Ingress API to GA.](https://github.com/kubernetes/enhancements/tree/master/keps/sig-network/1453-ingress-api#122)
+
+During our last community meeting the group has decided to continue to 
+support Kubernetes versions older than 1.22 with ingress version 0.46.0 
+for six months after the release of Kubernetes 1.22 with only CVE and 
+crashes only fixes, on a rolling basis. There will be a separate branch and 
+release of Ingress-NGINX to support this very similar to how Kubernetes 
+project proper does. As we advance the Ingress-NGINX project, the mainline 
+will support Kubernetes 1.22 and above, similar to the maintainers of the 
+Kubernetes project as a whole.

+Kubernetes Version  | Ingress-NGINX version | Support Notes
+:-------------------|:----------------------|:------------
+`1.22`              | TBD                   | On Going
+`1.21`              | `v0.46.0`             | On Going but only CVE and crashes
+`1.20`              | `v0.46.0`             | On Going but only CVE and crashes
+`1.19`              | `v0.46.0`             | Support will drop 6 months after 1.22 release

+
+Because of the networking v1 update going GA in Kubernetes 1.22, `v0.46.0` will 
+not work with Kubernetes 1.22. 
+
+# What do I need to do
+
+The team is currently in the process of upgrading ingress-nginx to support 
+the v1 migration, you can track the progress 
+[here](https://github.com/kubernetes/ingress-nginx/pull/7156).  This also 
+means the feature requests are being frozen until the v1 update is completed. 
+
+In the meantime to ensure no compatibility issues: 
+
+* Update to the latest version of Ingress-NGINX, currently [v0.46.0](https://github.com/kubernetes/ingress-nginx/releases/tag/controller-v0.46.0) 
+* After Kubernetes 1.22 is released, ensure you are using the latest version of 
+  Ingress-NGINX that supports v1 networking api.
+
+The community’s feedback and support in this effort is welcome. The
+Ingress-Nginx Sub-project regularly hold community meetings where we discuss
+this and other issues facing the project, meeting notes and details are
+[here](https://github.com/kubernetes/community/tree/master/sig-network)
