# Traefik & Knative
The Traefik Knative provider integrates with Knative Serving to provide advanced traffic management and routing capabilities for serverless applications.
[Knative](https://knative.dev) is a Kubernetes-based platform that enables serverless workloads with features like scale-to-zero,
automatic scaling, and revision management.
The provider watches Knative `Ingress` resources and automatically configures Traefik routing rules,
enabling seamless integration between Traefik's networking capabilities and Knative's serverless platform.
## Requirements
{!kubernetes-requirements.md!}
1. Install/update the Knative CRDs.
```bash
kubectl apply -f https://github.com/knative/serving/releases/download/knative-v1.19.0/serving-crds.yaml
```
2. Install the Knative Serving core components.
```bash
kubectl apply -f https://github.com/knative/serving/releases/download/knative-v1.19.0/serving-core.yaml
```
3. Update the config-network configuration to use the Traefik ingress class.
```bash
kubectl patch configmap/config-network \
-n knative-serving \
--type merge \
-p '{"data":{"ingress.class":"traefik.ingress.networking.knative.dev"}}'
```
4. Add a custom domain to your Knative configuration (Optional).
```bash
kubectl patch configmap config-domain \
-n knative-serving \
--type='merge' \
-p='{"data":{"example.com":""}}'
```
5. Install/update the Traefik [RBAC](../../../dynamic-configuration/kubernetes-knative-rbac.yml).
```bash
kubectl apply -f https://raw.githubusercontent.com/traefik/traefik/v3.6/docs/content/reference/dynamic-configuration/kubernetes-knative-rbac.yml
```
## Configuration Example
As this provider is an experimental feature, it needs to be enabled in the experimental and in the provider sections of the configuration.
You can enable the Knative provider as detailed below:
```yaml tab="File (YAML)"
experimental:
knative: true
providers:
knative: {}
```
```toml tab="File (TOML)"
[experimental.knative]
[providers.knative]
```
```bash tab="CLI"
--experimental.knative=true
--providers.knative=true
```
The Knative provider uses the Knative API to retrieve its routing configuration.
The provider then watches for incoming Knative events and derives the corresponding dynamic configuration from it.

<!-- markdownlint-enable MD013 -->
### `endpoint`
The Kubernetes server endpoint URL.
When deployed into Kubernetes, Traefik reads the environment variables `KUBERNETES_SERVICE_HOST` and `KUBERNETES_SERVICE_PORT` or `KUBECONFIG` to construct the endpoint.
The access token is looked up in `/var/run/secrets/kubernetes.io/serviceaccount/token` and the SSL CA certificate in `/var/run/secrets/kubernetes.io/serviceaccount/ca.crt`.
Both are mounted automatically when deployed inside Kubernetes.
The endpoint may be specified to override the environment variable values inside a cluster.
When the environment variables are not found, Traefik tries to connect to the Knative API server with an external-cluster client.
In this case, the endpoint is required.
Specifically, it may be set to the URL used by `kubectl proxy` to connect to a Knative cluster using the granted authentication and authorization of the associated kubeconfig.
```yaml tab="File (YAML)"
providers:
knative:
endpoint: "http://localhost:8080"
# ...
```
```toml tab="File (TOML)"
[providers.knative]
endpoint = "http://localhost:8080"
# ...
```
```bash tab="CLI"
--providers.knative.endpoint=http://localhost:8080
```

# Traefik & Knative
When using the Knative provider, Traefik leverages Knative's Custom Resource Definitions (CRDs) to obtain its routing configuration.
For detailed information on Knative concepts and resources, refer to the official [documentation](https://knative.dev/docs/).
The Knative provider supports version [v1.19.0](https://github.com/knative/serving/releases/tag/knative-v1.19.0) of the specification.
## Deploying a Knative Service
A `Service` is a core resource in the Knative specification that defines the entry point for traffic into a Knative application.
It is linked to a `Ingress`, which specifies the Knative networking controller responsible for managing and handling the traffic,
ensuring that it is directed to the appropriate Knative backend services.
The following `Service` manifest configures the running Traefik controller to handle the incoming traffic.
```yaml
---
apiVersion: serving.knative.dev/v1
kind: Service
metadata:
name: helloworld-go
namespace: default
spec:
template:
spec:
containers:
- image: gcr.io/knative-samples/helloworld-go
env:
- name: TARGET
value: "Go Sample v1"
```
Once everything is deployed, sending a `GET` request to the HTTP endpoint should return the following response:
```shell
$ curl http://helloworld-go.default.example.com
Hello Go Sample v1!
```
!!! Note
The `example.com` domain is the public domain configured when deploying the Traefik controller.
Check out [the install configuration](../../install-configuration/providers/kubernetes/knative.md) for more details.
### Tag based routing
To add tag-based routing with percentage in Knative, you can define the `traffic` section in your `Service` manifest to include different revisions with specific tags and percentages.
Here is an example:
```yaml
apiVersion: serving.knative.dev/v1
kind: Service
metadata:
name: helloworld-go
namespace: default
spec:
template:
spec:
containers:
- image: gcr.io/knative-samples/helloworld-go
env:
- name: TARGET
value: "Go Sample v2"
traffic:
- tag: v1
revisionName: helloworld-go-00001
percent: 50
- tag: v2
revisionName: helloworld-go-00002
percent: 50
```
In this example:
- The `traffic` section specifies two revisions (`helloworld-go-00001` and `helloworld-go-00002`) with tags `v1` and `v2`, each receiving 50% of the traffic.
- The `tag` field allows you to route traffic to specific revisions using the tag.
You can access the tagged revisions using these URLs:
- `http://v1-helloworld-go.default.example.com`
- `http://v2-helloworld-go.default.example.com`
Use the default URL to access percentage-based routing:
- `http://helloworld-go.default.example.com`
### HTTP/HTTPS
Check out the Knative documentation for [HTTP/HTTPS configuration](https://knative.dev/docs/serving/encryption/external-domain-tls/#configure-external-domain-encryption).
