For the first time, an option to jail/chroot the nginx process, inside the controller container, is being introduced. This provides an additional layer of security, for sensitive information like K8S serviceaccounts. This release also brings a special new feature of deep inspection into objects. The inspection is a walk through of all the spec, checking for possible attempts to escape configs. Currently such an inspection only occurs for `networking.Ingress`. Additionally there are fixes for the recently announced CVEs on busybox & ssl_client. And there is a fix to a recently introduced redirection related bug, that was setting the protocol on URLs to "nil". + +_Changes:_ + +- [8481](https://github.com/kubernetes/ingress-nginx/pull/8481)

In the CI pipeline workflow of GitHub actions (.github/workflows/ci.yaml), you can see how helm-docs is used. The CI pipeline is not designed to make commits back into the project, so we need to run helm-docs manually and commit the resulting generated README.md.

Edit the changelog + + [Changelog.md](https://github.com/kubernetes/ingress-nginx/blob/main/Changelog.md) +- Each time a release is made, a new section is added to the Changelog.md file +- A new section in the Changelog.md file consists of 3 components listed below + - the "Image" + - the "Description" + - the "PRs list" +- Look at the previous content to understand what the 3 components look like. +- You can easily get the "Image" from a yaml manifest but be sure to look at a manifest in your git clone now and not the upstream on github. This is because, if you are following this documentation, then you generated manifests with new updated digest for the image, in step 4e above. You also most likely promoted the new image in a step above. Look at the previous release section in Changelog.md. The format looks like `registry.k8s.io/ingress-nginx/controller:.......`. One example of a yaml file to look at is /deploy/static/provider/baremetal/deploy.yaml (in your git clone branch and not on the upstream). +- Next, you need to have a good overview of the changes introduced in this release and based on that you write a description. Look at previous descriptions. Ask the ingress-nginx-dev channel if required. +- And then you need to add a list of the PRs merged, since the previous release. +- One process to generate this list of PRs is already described above in step 4c. So if you are following this document, then you have done this already and very likely have retained the file containing the list of PRs, in the format that is needed. + +### g.

As the `ingress-nginx/ingress-nginx` chart continues to update, you will want to check current differences by running [helm configuration](#configuration) commands on both charts. + +## Configuration + +See [Customizing the Chart Before Installing](https://helm.sh/docs/intro/using_helm/#customizing-the-chart-before-installing). To see all configurable options with detailed comments, visit the chart's [values.yaml](./values.yaml), or run these configuration commands: + +```console +helm show values ingress-nginx/ingress-nginx +``` + +### PodDisruptionBudget + +Note that the PodDisruptionBudget resource will only be defined if the replicaCount is greater than one, +else it would make it impossible to evacuate a node. See [gh issue #7127](https://github.com/helm/charts/issues/7127) for more info. + +### Prometheus Metrics + +The Ingress-Nginx Controller can export Prometheus metrics, by setting `controller.metrics.enabled` to `true`. + +You can add Prometheus annotations to the metrics service using `controller.metrics.service.annotations`. +Alternatively, if you use the Prometheus Operator, you can enable ServiceMonitor creation using `controller.metrics.serviceMonitor.enabled`. And set `controller.metrics.serviceMonitor.additionalLabels.release="prometheus"`. "release=prometheus" should match the label configured in the prometheus servicemonitor ( see `kubectl get servicemonitor prometheus-kube-prom-prometheus -oyaml -n prometheus`) + +### ingress-nginx nginx\_status page/stats server + +Previous versions of this chart had a `controller.stats.*` configuration block, which is now obsolete due to the following changes in Ingress-Nginx Controller: + +- In [0.16.1](https://github.com/kubernetes/ingress-nginx/blob/main/Changelog.md#0161), the vts (virtual host traffic status) dashboard was removed +- In [0.23.0](https://github.com/kubernetes/ingress-nginx/blob/main/Changelog.md#0230), the status page at port 18080 is now a unix socket webserver only available at localhost. + You can use `curl --unix-socket /tmp/nginx-status-server.sock http://localhost/nginx_status` inside the controller container to access it locally, or use the snippet from [nginx-ingress changelog](https://github.com/kubernetes/ingress-nginx/blob/main/Changelog.md#0230) to re-enable the http server + +### ExternalDNS Service Configuration + +Add an [ExternalDNS](https://github.com/kubernetes-sigs/external-dns) annotation to the LoadBalancer service: + +```yaml +controller: + service: + annotations: + external-dns.alpha.kubernetes.io/hostname: kubernetes-example.com. +``` + +### AWS L7 ELB with SSL Termination + +Annotate the controller as shown in the [nginx-ingress l7 patch](https://github.com/kubernetes/ingress-nginx/blob/ab3a789caae65eec4ad6e3b46b19750b481b6bce/deploy/aws/l7/service-l7.yaml): + +```yaml +controller: + service: + targetPorts: + http: http + https: http + annotations: + service.beta.kubernetes.io/aws-load-balancer-ssl-cert: arn:aws:acm:XX-XXXX-X:XXXXXXXXX:certificate/XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXX + service.beta.kubernetes.io/aws-load-balancer-backend-protocol: "http" + service.beta.kubernetes.io/aws-load-balancer-ssl-ports: "https" + service.beta.kubernetes.io/aws-load-balancer-connection-idle-timeout: '3600' +``` + +### Additional Internal Load Balancer + +This setup is useful when you need both external and internal load balancers but don't want to have multiple ingress controllers and multiple ingress objects per application. + +By default, the ingress object will point to the external load balancer address, but if correctly configured, you can make use of the internal one if the URL you are looking up resolves to the internal load balancer's URL. + +You'll need to set both the following values: + +`controller.service.internal.enabled` +`controller.service.internal.annotations` + +If one of them is missing the internal load balancer will not be deployed. Example you may have `controller.service.internal.enabled=true` but no annotations set, in this case no action will be taken. + +`controller.service.internal.annotations` varies with the cloud service you're using. + +Example for AWS: + +```yaml +controller: + service: + internal: + enabled: true + annotations: + # Create internal NLB + service.beta.kubernetes.io/aws-load-balancer-scheme: "internal" + # Create internal ELB(Deprecated) + # service.beta.kubernetes.io/aws-load-balancer-internal: "true" + # Any other annotation can be declared here. +``` + +Example for GCE: + +```yaml +controller: + service: + internal: + enabled: true + annotations: + # Create internal LB. More information: https://cloud.google.com/kubernetes-engine/docs/how-to/internal-load-balancing + # For GKE versions 1.17 and later + networking.gke.io/load-balancer-type: "Internal" + # For earlier versions + # cloud.google.com/load-balancer-type: "Internal" + + # Any other annotation can be declared here. +``` + +Example for Azure: + +```yaml +controller: + service: + annotations: + # Create internal LB + service.beta.kubernetes.io/azure-load-balancer-internal: "true" + # Any other annotation can be declared here. +``` + +Example for Oracle Cloud Infrastructure: + +```yaml +controller: + service: + annotations: + # Create internal LB + service.beta.kubernetes.io/oci-load-balancer-internal: "true" + # Any other annotation can be declared here. +``` + +The load balancer annotations of more cloud service providers can be found: [Internal load balancer](https://kubernetes.io/docs/concepts/services-networking/service/#internal-load-balancer). + +An use case for this scenario is having a split-view DNS setup where the public zone CNAME records point to the external balancer URL while the private zone CNAME records point to the internal balancer URL. This way, you only need one ingress kubernetes object. + +Optionally you can set `controller.service.loadBalancerIP` if you need a static IP for the resulting `LoadBalancer`. + +### Ingress Admission Webhooks + +With nginx-ingress-controller version 0.25+, the Ingress-Nginx Controller pod exposes an endpoint that will integrate with the `validatingwebhookconfiguration` Kubernetes feature to prevent bad ingress from being added to the cluster. +**This feature is enabled by default since 0.31.0.** + +With nginx-ingress-controller in 0.25.* work only with kubernetes 1.14+, 0.26 fix [this issue](https://github.com/kubernetes/ingress-nginx/pull/4521) + +#### How the Chart Configures the Hooks +A validating and configuration requires the endpoint to which the request is sent to use TLS. It is possible to set up custom certificates to do this, but in most cases, a self-signed certificate is enough. The setup of this component requires some more complex orchestration when using helm. The steps are created to be idempotent and to allow turning the feature on and off without running into helm quirks. + +1. A pre-install hook provisions a certificate into the same namespace using a format compatible with provisioning using end user certificates. If the certificate already exists, the hook exits. +2. The Ingress-Nginx Controller pod is configured to use a TLS proxy container, which will load that certificate. +3. Validating and Mutating webhook configurations are created in the cluster. +4. A post-install hook reads the CA from the secret created by step 1 and patches the Validating and Mutating webhook configurations. This process will allow a custom CA provisioned by some other process to also be patched into the webhook configurations. The chosen failure policy is also patched into the webhook configurations + +#### Alternatives +It should be possible to use [cert-manager/cert-manager](https://github.com/cert-manager/cert-manager) if a more complete solution is required. + +You can enable automatic self-signed TLS certificate provisioning via cert-manager by setting the `controller.admissionWebhooks.certManager.enabled` value to true. + +Please ensure that cert-manager is correctly installed and configured. + +### Helm Error When Upgrading: spec.clusterIP: Invalid value: "" + +If you are upgrading this chart from a version between 0.31.0 and 1.2.2 then you may get an error like this: + +```console +Error: UPGRADE FAILED: Service "?????-controller" is invalid: spec.clusterIP: Invalid value: "": field is immutable +``` + +Detail of how and why are in [this issue](https://github.com/helm/charts/pull/13646) but to resolve this you can set `xxxx.service.omitClusterIP` to `true` where `xxxx` is the service referenced in the error. + +As of version `1.26.0` of this chart, by simply not providing any clusterIP value, `invalid: spec.clusterIP: Invalid value: "": field is immutable` will no longer occur since `clusterIP: ""` will not be rendered. + +### Pod Security Admission + +You can use Pod Security Admission by applying labels to the `ingress-nginx` namespace as instructed by the [documentation](https://kubernetes.io/docs/tasks/configure-pod-container/enforce-standards-namespace-labels). + +Example: + +```yaml +apiVersion: v1 +kind: Namespace +metadata: + name: ingress-nginx + labels: + kubernetes.io/metadata.name: ingress-nginx + name: ingress-nginx + pod-security.kubernetes.io/enforce: restricted + pod-security.kubernetes.io/enforce-version: v1.31 +``` + +{{ template "chart.valuesSection" . }} diff --git a/charts/ingress-nginx/changelog/helm-chart-2.10.0.md b/charts/ingress-nginx/changelog/helm-chart-2.10.0.md new file mode 100644 index 000000000..b42d6c28b --- /dev/null +++ b/charts/ingress-nginx/changelog/helm-chart-2.10.0.md @@ -0,0 +1,9 @@ +# Changelog + +This file documents all notable changes to [ingress-nginx](https://github.com/kubernetes/ingress-nginx) Helm Chart.

The "kubectl port-forward..." command above has forwarded the port number 8080, on the localhost's tcp/ip stack, where the command was typed, to the port number 80, of the service created by the installation of ingress-nginx controller. So now, the traffic sent to port number 8080 on localhost will reach the port number 80, of the ingress-controller's service. + Port-forwarding is not for a production environment use-case. But here we use port-forwarding, to simulate a HTTP request, originating from outside the cluster, to reach the service of the ingress-nginx controller, that is exposed to receive traffic from outside the cluster. + [This issue](https://github.com/kubernetes/ingress-nginx/issues/10014#issuecomment-1567791549described) shows a typical DNS problem and its solution. + +At this point, you can access your deployment using curl ; + +```console +curl --resolve demo.localdev.me:8080:127.0.0.1 http://demo.localdev.me:8080 +``` + +You should see a HTML response containing text like **"It works!"**. + +### Online testing + +If your Kubernetes cluster is a "real" cluster that supports services of type `LoadBalancer`, it will have allocated an +external IP address or FQDN to the ingress controller. + +You can see that IP address or FQDN with the following command: + +```console +kubectl get service ingress-nginx-controller --namespace=ingress-nginx +``` + +It will be the `EXTERNAL-IP` field. If that field shows ``, this means that your Kubernetes cluster wasn't +able to provision the load balancer (generally, this is because it doesn't support services of type `LoadBalancer`). + +Once you have the external IP address (or FQDN), set up a DNS record pointing to it. Then you can create an ingress +resource. The following example assumes that you have set up a DNS record for `www.demo.io`: + +```console +kubectl create ingress demo --class=nginx \ + --rule="www.demo.io/*=demo:80" +``` + +Alternatively, the above command can be rewritten as follows for the ```--rule``` command and below. + +```console +kubectl create ingress demo --class=nginx \ + --rule www.demo.io/=demo:80 +``` + +You should then be able to see the "It works!" page when you connect to .

The command `kubectl get nodes` should show a +single node called `docker-desktop`. + +The ingress controller can be installed on Docker Desktop using the default [quick start](#quick-start) instructions. + +On most systems, if you don't have any other service of type `LoadBalancer` bound to port 80, the ingress controller +will be assigned the `EXTERNAL-IP` of `localhost`, which means that it will be reachable on localhost:80. If that +doesn't work, you might have to fall back to the `kubectl port-forward` method described in the +[local testing section](#local-testing). + +#### Rancher Desktop + +Rancher Desktop provides Kubernetes and Container Management on the desktop. Kubernetes is enabled by default in Rancher Desktop. + +Rancher Desktop uses K3s under the hood, which in turn uses Traefik as the default ingress controller for the Kubernetes cluster. To use Ingress-Nginx Controller in place of the default Traefik, disable Traefik from Preference > Kubernetes menu. + +Once traefik is disabled, the Ingress-Nginx Controller can be installed on Rancher Desktop using the default [quick start](#quick-start) instructions. Follow the instructions described in the [local testing section](#local-testing) to try a sample. + +### Cloud deployments + +If the load balancers of your cloud provider do active healthchecks on their backends (most do), you can change the +`externalTrafficPolicy` of the ingress controller Service to `Local` (instead of the default `Cluster`) to save an +extra hop in some cases. If you're installing with Helm, this can be done by adding +`--set controller.service.externalTrafficPolicy=Local` to the `helm install` or `helm upgrade` command. + +Furthermore, if the load balancers of your cloud provider support the PROXY protocol, you can enable it, and it will +let the ingress controller see the real IP address of the clients. Otherwise, it will generally see the IP address of +the upstream load balancer. This must be done both in the ingress controller +(with e.g. `--set controller.config.use-proxy-protocol=true`) and in the cloud provider's load balancer configuration +to function correctly. + +In the following sections, we provide YAML manifests that enable these options when possible, using the specific +options of various cloud providers. + +#### AWS + +In AWS, we use a Network load balancer (NLB) to expose the Ingress-Nginx Controller behind a Service of `Type=LoadBalancer`. + +!!! info + The provided templates illustrate the setup for legacy in-tree service load balancer for AWS NLB. + AWS provides the documentation on how to use + [Network load balancing on Amazon EKS](https://docs.aws.amazon.com/eks/latest/userguide/network-load-balancing.html) + with [AWS Load Balancer Controller](https://github.com/kubernetes-sigs/aws-load-balancer-controller). + +##### Network Load Balancer (NLB) + +```console +kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.12.0/deploy/static/provider/aws/deploy.yaml +``` + +##### TLS termination in AWS Load Balancer (NLB) + +By default, TLS is terminated in the ingress controller.

The plugin manager uses convention over configuration -strategy and automatically runs functions defined in `main.lua` in the corresponding Nginx phase based on their name. - -Nginx has different [request processing phases](http://nginx.org/en/docs/dev/development_guide.html#http_phases). -By defining functions with the following names, you can run your custom Lua code in the corresponding Nginx phase: - - - `init_worker`: useful for initializing some data per Nginx worker process - - `rewrite`: useful for modifying request, changing headers, redirection, dropping request, doing authentication etc - - `header_filter`: this is called when backend response header is received, it is useful for modifying response headers - - `body_filter`: this is called when response body is received, it is useful for logging response body - - `log`: this is called when request processing is completed and a response is delivered to the client - -Check this [`hello_world`](https://github.com/kubernetes/ingress-nginx/tree/master/rootfs/etc/nginx/lua/plugins/hello_world) plugin as a simple example or refer to [OpenID Connect integration](https://github.com/ElvinEfendi/ingress-nginx-openidc/tree/master/rootfs/etc/nginx/lua/plugins/openidc) for more advanced usage. - -Do not forget to write tests for your plugin. - -### Installing a plugin - -There are two options: - - - mount your plugin into `/etc/nginx/lua/plugins/` in the ingress-nginx pod - - build your own ingress-nginx image like it is done in the [example](https://github.com/ElvinEfendi/ingress-nginx-openidc/tree/master/rootfs/etc/nginx/lua/plugins/openidc) and install your plugin during image build - -Mounting is the quickest option. - -### Enabling plugins - -Once your plugin is ready you need to use [`plugins` configuration setting](https://kubernetes.github.io/ingress-nginx/user-guide/nginx-configuration/configmap/#plugins) to activate it. Let's say you want to active `hello_world` and `open_idc` plugins, then you set `plugins` setting to `"hello_world, open_idc"`. _Note_ that the plugins will be executed in the given order. diff --git a/rootfs/etc/nginx/lua/plugins/hello_world/main.lua b/rootfs/etc/nginx/lua/plugins/hello_world/main.lua deleted file mode 100644 index 03316c3ee..000000000 --- a/rootfs/etc/nginx/lua/plugins/hello_world/main.lua +++ /dev/null @@ -1,13 +0,0 @@ -local ngx = ngx -
