## Advanced Use Cases
|
||||
|
||||
### Exposing gRPC Services
|
||||
|
||||
Traefik Proxy supports gRPC applications without requiring specific configuration. You can expose gRPC services using either HTTP (h2c) or HTTPS.
|
||||
|
||||
??? example "Using HTTP (h2c)"
|
||||
|
||||
For unencrypted gRPC communication, configure your service to use the `h2c://` protocol scheme:
|
||||
|
||||
```yaml
|
||||
http:
|
||||
routers:
|
||||
grpc-router:
|
||||
service: grpc-service
|
||||
rule: Host(`grpc.example.com`)
|
||||
|
||||
services:
|
||||
grpc-service:
|
||||
loadBalancer:
|
||||
servers:
|
||||
- url: h2c://backend:8080
|
||||
```
|
||||
|
||||
!!! note
|
||||
For providers with labels (Docker, Kubernetes), specify the scheme using:
|
||||
`traefik.http.services.<service-name>.loadbalancer.server.scheme=h2c`
|
||||
|
||||
??? example "Using HTTPS"
|
||||
|
||||
For encrypted gRPC communication, use standard HTTPS URLs. Traefik will use HTTP/2 over TLS to communicate with your gRPC backend:
|
||||
|
||||
```yaml
|
||||
http:
|
||||
routers:
|
||||
grpc-router:
|
||||
service: grpc-service
|
||||
rule: Host(`grpc.example.com`)
|
||||
tls: {}
|
||||
|
||||
services:
|
||||
grpc-service:
|
||||
loadBalancer:
|
||||
servers:
|
||||
- url: https://backend:8080
|
||||
```
|
||||
|
||||
Traefik handles the protocol negotiation automatically. Configure TLS certificates for your backends using [ServersTransport](../reference/routing-configuration/http/load-balancing/serverstransport.md) if needed.
|
||||
|
||||
### Exposing WebSocket Services
|
||||
|
||||
Traefik Proxy supports WebSocket (WS) and WebSocket Secure (WSS) connections out of the box. No special configuration is required beyond standard HTTP routing.
|
||||
|
||||
??? example "Basic WebSocket"
|
||||
|
||||
Configure a router and service pointing to your WebSocket server. Traefik automatically detects and handles the WebSocket upgrade:
|
||||
|
||||
```yaml
|
||||
http:
|
||||
routers:
|
||||
websocket-router:
|
||||
rule: Host(`ws.example.com`)
|
||||
service: websocket-service
|
||||
|
||||
services:
|
||||
websocket-service:
|
||||
loadBalancer:
|
||||
servers:
|
||||
- url: http://websocket-backend:8000
|
||||
```
|
||||
|
||||
??? example "WebSocket Secure (WSS)"
|
||||
|
||||
For encrypted WebSocket connections, enable TLS on your router. Clients connect using `wss://` while you can choose whether backends use encrypted or unencrypted connections:
|
||||
|
||||
```yaml
|
||||
http:
|
||||
routers:
|
||||
websocket-secure-router:
|
||||
rule: Host(`wss.example.com`)
|
||||
service: websocket-service
|
||||
tls: {}
|
||||
|
||||
services:
|
||||
websocket-service:
|
||||
loadBalancer:
|
||||
servers:
|
||||
- url: http://websocket-backend:8000 # SSL termination at Traefik
|
||||
# OR
|
||||
# - url: https://websocket-backend:8443 # End-to-end encryption
|
||||
```
|
||||
|
||||
Traefik preserves WebSocket headers including `Origin`, `Sec-WebSocket-Key`, and `Sec-WebSocket-Version`. Use the [Headers middleware](../reference/routing-configuration/http/middlewares/headers.md) if you need to modify headers for origin checking or other requirements.

Provision TLS Certificate for Traefik Proxy with cert-manager on Kubernetes
|
||||
{: .subtitle }
|
||||
|
||||
## Pre-requisites
|
||||
|
||||
To obtain certificates from cert-manager that can be used in Traefik Proxy, you will need to:
|
||||
|
||||
1. Have cert-manager properly configured
|
||||
2. Have Traefik Proxy configured
|
||||
|
||||
The certificates can then be used in an Ingress / IngressRoute / HTTPRoute.
|
||||
|
||||

## Troubleshooting
|
||||
|
||||
There are multiple event sources available to investigate when using cert-manager:
|
||||
|
||||
1. Kubernetes events in `Certificate` and `CertificateRequest` resources
|
||||
2. cert-manager logs
|
||||
3. Dashboard and/or (debug) logs from Traefik Proxy
|
||||
|
||||
cert-manager documentation provides a [detailed guide](https://cert-manager.io/docs/troubleshooting/) on how to troubleshoot a certificate request.

# Traefik & CRD & Let's Encrypt
|
||||
|
||||
Traefik with an IngressRoute Custom Resource Definition for Kubernetes, and TLS Through Let's Encrypt.
|
||||
{: .subtitle }
|
||||
|
||||
This document is intended to be a fully working example demonstrating how to set up Traefik in [Kubernetes](https://kubernetes.io),
|
||||
with the dynamic configuration coming from the [IngressRoute Custom Resource](../../providers/kubernetes-crd.md),
|
||||
and TLS setup with [Let's Encrypt](https://letsencrypt.org).
|
||||
However, for the sake of simplicity, we're using [k3s](https://github.com/rancher/k3s) docker image for the Kubernetes cluster setup.
|
||||
|
||||
Please note that for this setup, given that we're going to use ACME's TLS-ALPN-01 challenge, the host you'll be running it on must be able to receive connections from the outside on port 443.
|
||||
And of course its internet facing IP address must match the domain name you intend to use.
|
||||
|
||||
In the following, the Kubernetes resources defined in YAML configuration files can be applied to the setup in two different ways:
|
||||
|
||||
- the first, and usual way, is simply with the `kubectl apply` command.
|
||||
- the second, which can be used for this tutorial, is to directly place the files in the directory used by the k3s docker image for such inputs (`/var/lib/rancher/k3s/server/manifests`).
|
||||
|
||||
!!! important "Kubectl Version"
|
||||
|
||||
With the `rancher/k3s` version used in this guide (`0.8.0`), the kubectl version needs to be >= `1.11`.
|
||||
|
||||
## k3s Docker-compose Configuration
|
||||
|
||||
Our starting point is the docker-compose configuration file, to start the k3s cluster.
|
||||
You can start it with:
|
||||
|
||||
```bash
|
||||
docker compose -f k3s.yml up
|
||||
```
|
||||
|
||||
```yaml
|
||||
--8<-- "content/user-guides/crd-acme/k3s.yml"
|
||||
```
|
||||
|
||||
## Cluster Resources
|
||||
|
||||
Let's now have a look (in the order they should be applied, if using `kubectl apply`) at all the required resources for the full setup.
|
||||
|
||||
### IngressRoute Definition
|
||||
|
||||
First, you will need to install Traefik CRDs containing the definition of the `IngressRoute` and the `Middleware` kinds,
|
||||
and the RBAC authorization resources which will be referenced through the `serviceAccountName` of the deployment.
|
||||
|
||||
```bash
|
||||
# Install Traefik Resource Definitions:
|
||||
kubectl apply -f https://raw.githubusercontent.com/traefik/traefik/v3.6/docs/content/reference/dynamic-configuration/kubernetes-crd-definition-v1.yml
|
||||
|
||||
# Install RBAC for Traefik:
|
||||
kubectl apply -f https://raw.githubusercontent.com/traefik/traefik/v3.6/docs/content/reference/dynamic-configuration/kubernetes-crd-rbac.yml
|
||||
```
|
||||
|
||||
### Services
|
||||
|
||||
Then, the services. One for Traefik itself, and one for the app it routes for, i.e. in this case our demo HTTP server: [whoami](https://github.com/traefik/whoami).
|
||||
|
||||
```bash
|
||||
kubectl apply -f https://raw.githubusercontent.com/traefik/traefik/v3.6/docs/content/user-guides/crd-acme/02-services.yml
|
||||
```
|
||||
|
||||
```yaml
|
||||
--8<-- "content/user-guides/crd-acme/02-services.yml"
|
||||
```
|
||||
|
||||
### Deployments
|
||||
|
||||
Next, the deployments, i.e. the actual pods behind the services.
|
||||
Again, one pod for Traefik, and one for the whoami app.
|
||||
|
||||
```bash
|
||||
kubectl apply -f https://raw.githubusercontent.com/traefik/traefik/v3.6/docs/content/user-guides/crd-acme/03-deployments.yml
|
||||
```
|
||||
|
||||
```yaml
|
||||
--8<-- "content/user-guides/crd-acme/03-deployments.yml"
|
||||
```
|
||||
|
||||
### Port Forwarding
|
||||
|
||||
Now, as an exception to what we said above, please note that you should not let the ingressRoute resources below be applied automatically to your cluster.
|
||||
The reason is, as soon as the ACME provider of Traefik detects we have TLS routers, it will try to generate the certificates for the corresponding domains.
|
||||
And this will not work, because as it is, our Traefik pod is not reachable from the outside, which will make the ACME TLS challenge fail.
|
||||
Therefore, for the whole thing to work, we must delay applying the ingressRoute resources until we have port-forwarding set up properly, which is the next step.
|
||||
|
||||
```bash
|
||||
kubectl port-forward --address 0.0.0.0 service/traefik 8000:8000 8080:8080 443:4443 -n default
|
||||
```
|
||||
|
||||
Also, and this is out of the scope of this guide, please note that because of the privileged ports limitation on Linux, the above command might fail to listen on port 443.
|
||||
In which case you can use tricks such as elevating caps of `kubectl` with `setcaps`, or using `authbind`, or setting up a NAT between your host and the WAN.
|
||||
Look it up.
|
||||
|
||||
### Traefik Routers
|
||||
|
||||
We can now finally apply the actual ingressRoutes, with:
|
||||
|
||||
```bash
|
||||
kubectl apply -f https://raw.githubusercontent.com/traefik/traefik/v3.6/docs/content/user-guides/crd-acme/04-ingressroutes.yml
|
||||
```
|
||||
|
||||
```yaml
|
||||
--8<-- "content/user-guides/crd-acme/04-ingressroutes.yml"
|
||||
```
|
||||
|
||||
Give it a few seconds for the ACME TLS challenge to complete, and you should then be able to access your whoami pod (routed through Traefik), from the outside.
|
||||
Both with or (just for fun, do not do that in production) without TLS:
|
||||
|
||||
```bash
|
||||
curl [-k] https://your.example.com/tls
|
||||
```
|
||||
|
||||
```bash
|
||||
curl http://your.example.com:8000/notls
|
||||
```
|
||||
|
||||
Note that you'll have to use `-k` as long as you're using the staging server of Let's Encrypt, since it is not an authorized certificate authority on systems where it hasn't been manually added.
|
||||
|
||||
### Force TLS v1.2+
|
||||
|
||||
Nowadays, TLS v1.0 and v1.1 are deprecated.
|
||||
In order to force TLS v1.2 or later on all your IngressRoute, you can define the `default` TLSOption:
|
||||
|
||||
```bash
|
||||
kubectl apply -f https://raw.githubusercontent.com/traefik/traefik/v3.6/docs/content/user-guides/crd-acme/05-tlsoption.yml
|
||||

|
||||
|
||||
!!! warning
|
||||
For providers with labels, you will have to specify the `traefik.http.services.<my-service-name>.loadbalancer.server.scheme=h2c`
|
||||
|
||||
### Conclusion
|
||||
|
||||
We don't need specific configuration to use gRPC in Traefik, we just need to use `h2c` protocol, or use HTTPS communications to have HTTP2 with the backend.
|
||||
|
||||
## With HTTPS
|
||||
|
||||
This section explains how to use Traefik as reverse proxy for gRPC application with self-signed certificates.
|
||||
|
||||
|
||||
|
||||
### gRPC Server Certificate
|
||||
|
||||
In order to secure the gRPC server, we generate a self-signed certificate for service url:
|
||||
|
||||
```bash
|
||||
openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout ./backend.key -out ./backend.cert
|
||||
```
|
||||
|
||||
That will prompt for information, the important answer is:
|
||||
|
||||
```txt
|
||||
Common Name (e.g. server FQDN or YOUR name) []: backend.local
|
||||
```
|
||||
|
||||
### gRPC Client Certificate
|
||||
|
||||
Generate your self-signed certificate for router url:
|
||||
|
||||
```bash
|
||||
openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout ./frontend.key -out ./frontend.cert
|
||||
```
|
||||
|
||||
with
|
||||
|
||||
```txt
|
||||
Common Name (e.g. server FQDN or YOUR name) []: frontend.local
|
||||
```
|
||||
|
||||
### Traefik Configuration
|
||||
|
||||
At last, we configure our Traefik instance to use both self-signed certificates.
|
||||
|
||||

|
||||
|
||||

|
||||
```
|
||||
|
||||
!!! warning
|
||||
With some services, the server URLs use the IP, so you may need to configure `insecureSkipVerify` instead of the `rootCAs` to activate HTTPS without hostname verification.
|
||||
|
||||
### A gRPC example in go (modify for https)
|
||||
|
||||
We use the gRPC greeter example in [grpc-go](https://github.com/grpc/grpc-go/tree/master/examples/helloworld)
|
||||
|
||||
!!! warning
|
||||
In order to use this gRPC example, we need to modify it to use HTTPS
|
||||
|
||||
So we modify the "gRPC server example" to use our own self-signed certificate:
|
||||
|
||||
```go
|
||||
// ...
|
||||
|
||||
// Read cert and key file
|
||||
backendCert, _ := os.ReadFile("./backend.cert")
|
||||
backendKey, _ := os.ReadFile("./backend.key")
|
||||
|
||||
// Generate Certificate struct
|
||||
cert, err := tls.X509KeyPair(backendCert, backendKey)
|
||||
if err != nil {
|
||||
log.Fatalf("failed to parse certificate: %v", err)
|
||||
}
|
||||
|
||||
// Create credentials
|
||||
creds := credentials.NewServerTLSFromCert(&cert)
|
||||
|
||||
// Use Credentials in gRPC server options
|
||||
serverOption := grpc.Creds(creds)
|
||||
var s *grpc.Server = grpc.NewServer(serverOption)
|
||||
defer s.Stop()
|
||||
|
||||
pb.RegisterGreeterServer(s, &server{})
|
||||
err := s.Serve(lis)
|
||||
|
||||
// ...
|
||||
```
|
||||
|
||||
Next we will modify gRPC Client to use our Traefik self-signed certificate:
|
||||
|
||||
```go
|
||||
// ...
|
||||
|
||||
// Read cert file
|
||||
frontendCert, _ := os.ReadFile("./frontend.cert")
|
||||
|
||||
// Create CertPool
|
||||
roots := x509.NewCertPool()
|
||||
roots.AppendCertsFromPEM(frontendCert)
|
||||
|
||||
// Create credentials
|
||||
credsClient := credentials.NewClientTLSFromCert(roots, "")
|
||||
|
||||
// Dial with specific Transport (with credentials)
|
||||
conn, err := grpc.Dial("frontend.local:4443", grpc.WithTransportCredentials(credsClient))
|
||||
if err != nil {
|
||||
log.Fatalf("did not connect: %v", err)
|
||||
}
|
||||
|
||||
defer conn.Close()
|
||||
client := pb.NewGreeterClient(conn)
|
||||
|
||||
name := "World"
|
||||
r, err := client.SayHello(context.Background(), &pb.HelloRequest{Name: name})
|

# WebSocket
|
||||
|
||||
Configuring Traefik to handle WebSocket and WebSocket Secure (WSS) connections.
|
||||
{: .subtitle }
|
||||
|
||||
## Overview
|
||||
|
||||
WebSocket is a communication protocol that provides full-duplex communication channels over a single TCP connection.
|
||||
WebSocket Secure (WSS) is the encrypted version of WebSocket, using TLS/SSL encryption.
|
||||
|
||||
Traefik supports WebSocket and WebSocket Secure (WSS) out of the box. This guide will walk through examples of how to configure Traefik for different WebSocket scenarios.
|
||||
|
||||
## Basic WebSocket Configuration
|
||||
|
||||
A basic WebSocket configuration only requires defining a router and a service that points to your WebSocket server.
|
||||
|
||||
```yaml tab="Docker & Swarm"
|
||||
labels:
|
||||
- "traefik.http.routers.my-websocket.rule=Host(`ws.example.com`)"
|
||||
- "traefik.http.routers.my-websocket.service=my-websocket-service"
|
||||
- "traefik.http.services.my-websocket-service.loadbalancer.server.port=8000"
|
||||
```
|
||||
|
||||
```yaml tab="Kubernetes"
|
||||
apiVersion: traefik.io/v1alpha1
|
||||
kind: IngressRoute
|
||||
metadata:
|
||||
name: my-websocket-route
|
||||
spec:
|
||||
entryPoints:
|
||||
- web
|
||||
routes:
|
||||
- match: Host(`ws.example.com`)
|
||||
kind: Rule
|
||||
services:
|
||||
- name: my-websocket-service
|
||||
port: 8000
|
||||
```
|
||||
|
||||
```yaml tab="File (YAML)"
|
||||
http:
|
||||
routers:
|
||||
my-websocket:
|
||||
rule: "Host(`ws.example.com`)"
|
||||
service: my-websocket-service
|
||||
|
||||
services:
|
||||
my-websocket-service:
|
||||
loadBalancer:
|
||||
servers:
|
||||
- url: "http://my-websocket-server:8000"
|
||||
```
|
||||
|
||||
```toml tab="File (TOML)"
|
||||
[http.routers]
|
||||
[http.routers.my-websocket]
|
||||
rule = "Host(`ws.example.com`)"
|
||||
service = "my-websocket-service"
|
||||
|
||||
[http.services]
|
||||
[http.services.my-websocket-service]
|
||||
[http.services.my-websocket-service.loadBalancer]
|
||||
[[http.services.my-websocket-service.loadBalancer.servers]]
|
||||
url = "http://my-websocket-server:8000"
|
||||
```
|
||||
|
||||
## WebSocket Secure (WSS) Configuration
|
||||
|
||||
WebSocket Secure (WSS) requires TLS configuration.
|
||||
The client connects using the `wss://` protocol instead of `ws://`.
|
||||
|
||||
```yaml tab="Docker & Swarm"
|
||||
labels:
|
||||
- "traefik.http.routers.my-websocket-secure.rule=Host(`wss.example.com`)"
|
||||
- "traefik.http.routers.my-websocket-secure.service=my-websocket-service"
|
||||
- "traefik.http.routers.my-websocket-secure.tls=true"
|
||||
- "traefik.http.services.my-websocket-service.loadbalancer.server.port=8000"
|
||||
```
|
||||
|
||||
```yaml tab="Kubernetes"
|
||||
apiVersion: traefik.io/v1alpha1
|
||||
kind: IngressRoute
|
||||
metadata:
|
||||
name: my-websocket-secure-route
|
||||
spec:
|
||||
entryPoints:
|
||||
- websecure
|
||||
routes:
|
||||
- match: Host(`wss.example.com`)
|
||||
kind: Rule
|
||||
services:
|
||||
- name: my-websocket-service
|
||||
port: 8000
|
||||
tls: {}
|
||||
```
|
||||
|
||||
```yaml tab="File (YAML)"
|
||||
http:
|
||||
routers:
|
||||
my-websocket-secure:
|
||||
rule: "Host(`wss.example.com`)"
|
||||
service: my-websocket-service
|
||||
tls: {}
|
||||
|
||||
services:
|
||||
my-websocket-service:
|
||||
loadBalancer:
|
||||
servers:
|
||||
- url: "http://my-websocket-server:8000"
|
||||
```
|
||||
|
||||
```toml tab="File (TOML)"
|
||||
[http.routers]
|
||||
[http.routers.my-websocket-secure]
|
||||
rule = "Host(`wss.example.com`)"
|
||||
service = "my-websocket-service"
|
||||
[http.routers.my-websocket-secure.tls]
|
||||
|
||||
[http.services]
|
||||
[http.services.my-websocket-service]
|
||||
[http.services.my-websocket-service.loadBalancer]
|
||||
[[http.services.my-websocket-service.loadBalancer.servers]]
|
||||
url = "http://my-websocket-server:8000"
|
||||
```
|
||||
|
||||
## SSL Termination for WebSockets
|
||||
|
||||
In this scenario, clients connect to Traefik using WSS (encrypted), but Traefik connects to your backend server using WS (unencrypted).
|
||||
This is called SSL termination.
|
||||
|
||||
```yaml tab="Docker & Swarm"
|
||||
labels:
|
||||
- "traefik.http.routers.my-wss-termination.rule=Host(`wss.example.com`)"
|
||||
- "traefik.http.routers.my-wss-termination.service=my-ws-service"
|
||||
- "traefik.http.routers.my-wss-termination.tls=true"
|
||||
- "traefik.http.services.my-ws-service.loadbalancer.server.port=8000"
|
||||
```
|
||||
|
||||
```yaml tab="Kubernetes"
|
||||
apiVersion: traefik.io/v1alpha1
|
||||
kind: IngressRoute
|
||||
metadata:
|
||||
name: my-wss-termination-route
|
||||
spec:
|

||||
|
||||
```yaml tab="File (YAML)"

|

|
||||
|
||||

|
||||
my-ws-service:
|
||||

|
||||

|
||||

|
||||
```
|
||||
|
||||
```toml tab="File (TOML)"
|
||||
[http.routers]
|
||||
[http.routers.my-wss-termination]
|
||||
rule = "Host(`wss.example.com`)"
|
||||
service = "my-ws-service"
|
||||
[http.routers.my-wss-termination.tls]

|
||||
url = "http://my-ws-server:8000"
|
||||
```
|
||||
|
||||
## End-to-End WebSocket Secure (WSS)
|
||||
|
||||
For end-to-end encryption, Traefik can be configured to connect to your backend using HTTPS.
|
||||
|
||||
```yaml tab="Docker & Swarm"
|
||||
labels:
|
||||
- "traefik.http.routers.my-wss-e2e.rule=Host(`wss.example.com`)"
|
||||
- "traefik.http.routers.my-wss-e2e.service=my-wss-service"
|
||||
- "traefik.http.routers.my-wss-e2e.tls=true"
|
||||
- "traefik.http.services.my-wss-service.loadbalancer.server.port=8443"
|
||||
# If the backend uses a self-signed certificate
|
||||
- "traefik.http.serversTransports.insecureTransport.insecureSkipVerify=true"
|
||||
- "traefik.http.services.my-wss-service.loadBalancer.serversTransport=insecureTransport"
|
||||
```
|
||||
|
||||
```yaml tab="Kubernetes"
|
||||
apiVersion: traefik.io/v1alpha1
|
||||
kind: ServersTransport
|
||||
metadata:
|
||||

```toml tab="File (TOML)"
|

|
||||
[[http.services.my-wss-service.loadBalancer.servers]]
|
||||
url = "https://my-wss-server:8443"
|
||||
```
|
||||
|
||||
## EntryPoints Configuration for WebSockets
|
||||
|
||||
In your Traefik static configuration, you'll need to define entryPoints for both WS and WSS:
|
||||
|
||||
```yaml tab="File (YAML)"
|
||||
entryPoints:
|
||||
web:
|
||||
address: ":80"
|
||||
websecure:
|
||||
address: ":443"
|
||||
```
|
||||
|
||||
```toml tab="File (TOML)"
|
||||
[entryPoints]
|
||||
[entryPoints.web]
|
||||
address = ":80"
|
||||
[entryPoints.websecure]
|
||||
address = ":443"
|
||||
```
|
||||
|
||||
## Testing WebSocket Connections
|
||||
|
||||
You can test your WebSocket configuration using various tools:
|
||||
|
||||
1. Browser Developer Tools: Most modern browsers include WebSocket debugging in their developer tools.
|
||||
2. WebSocket client tools like [wscat](https://github.com/websockets/wscat) or online tools like [Piesocket's WebSocket Tester](https://www.piesocket.com/websocket-tester).
|
||||
|
||||
Example wscat commands:
|
||||
|
||||
```bash
|
||||
# Test standard WebSocket
|
||||
wscat -c ws://ws.example.com
|
||||
|
||||
# Test WebSocket Secure
|
||||
wscat -c wss://wss.example.com
|
||||
```
|
||||
|
||||
## Common Issues and Solutions
|
||||
|
||||
### Headers and Origin Checks
|
||||
|
||||
Some WebSocket servers implement origin checking. Traefik passes the original headers to your backend, including the `Origin` header.
|
||||
|
||||
If you need to manipulate headers for WebSocket connections, you can use Traefik's Headers middleware:
|
||||
|
||||
```yaml tab="Docker & Swarm"
|
||||
labels:
|
||||
- "traefik.http.middlewares.my-headers.headers.customrequestheaders.Origin=https://allowed-origin.com"
|
||||
- "traefik.http.routers.my-websocket.middlewares=my-headers"
|
||||
```
|
||||
|
||||
```yaml tab="Kubernetes"
|
||||
apiVersion: traefik.io/v1alpha1
|
||||
kind: Middleware
|
||||
metadata:
|
||||
name: my-headers
|
||||
spec:
|
||||
headers:
|
||||
customRequestHeaders:
|
||||
Origin: "https://allowed-origin.com"

||||

|
||||
middlewares:
|
||||
- name: my-headers
|
||||
services:
|
||||
- name: my-websocket-service
|
||||
port: 8000
|
||||
```
|
||||
|
||||
### Certificate Issues with WSS
|
||||
|
||||
If you're experiencing certificate issues with WSS:
|
||||
|
||||
1. Ensure your certificates are valid and not expired
|
||||
2. For testing with self-signed certificates, configure your clients to accept them
|
||||
3. When using Let's Encrypt, ensure your domain is properly configured
|
||||
|
||||
For backends with self-signed certificates, use the `insecureSkipVerify` option in the ServersTransport configuration as shown in the examples above.
