Connect and share knowledge within a single location that is structured and easy to search. Is it possible to use tcp router with Ingress instead of IngressRouteTCP? Certificates to present to the server for mTLS. when the definition of the middleware comes from another provider. IngressRouteTCP is the CRD implementation of a Traefik TCP router. Traefik Proxy handles requests using web and webscure entrypoints. Thank you. The certificatesresolvers specify details about the Let's Encrypt account, Let's Encrypt challenge, Let's Encrypt servers, and the certificate storage. Routing Configuration for Traefik CRD - Traefik - Traefik Labs: Makes Join us to learn how to secure and expose applications and services using a combination of a SaaS network control plane and a lightweight, open source agent. It works out-of-the-box with Let's Encrypt, taking care of all TLS certificate management. When I temporarily enabled HTTP/3 on port 443, it worked. Save the configuration above as traefik-update.yaml and apply it to the cluster. I'm using caddy as an example of a secure application to simplify the setup and check if it works with traefik, because i already tested . The response contains an Alt-Svc HTTP header that indicates a UDP host and port over which the server can be reached through HTTP/3. Although you can configure Traefik Proxy to use multiple certificatesresolvers, an IngressRoute is only ever associated with a single one. From what I can tell the TCP connections that are being used between the Chrome browser and Traefik seem to get into some kind of invalid state and Chrome refuses to send anything over them until presumably they timeout. I was planning to use TLS passthrough in Traefik with TCP router to pass encrypted traffic to backend without decrypting it. with curl: assuming 10.42.0.6 is the IP address of one of the replicas (a pod then) of the whoami1 service. Here is my ingress: apiVersion: traefik.containo.us/v1alpha1 kind: IngressRouteTCP metadata: name: miab-websecure namespace: devusta spec: entryPoints: - websecure . Already on GitHub? Changing the config, parameters and/or mode of access in my humble opinion defeats the purpose. Traefik will only try to generate a Let's encrypt certificate (thanks to HTTP-01 challenge) if the domain cannot be checked by the provided certificates. @ReillyTevera If you have a public image that you already built, I can try it on my end too. I configured the container like so: With the tcp services, I still can't get Traefik to forward the raw TCP connections to this container. I need you to confirm if are you able to reproduce the results as detailed in the bug report. SSL is also a protocol for establishing authenticated and encrypted links between computers within a network. Create the following folder structure. For TCP and UDP Services use e.g.OpenSSL and Netcat. We just need any TLS passthrough service and a HTTP service using port 443. CLI. The backend needs to receive https requests. That's why I highly recommend moving our conversation to the Traefik Labs Community Forum. Alternatively, you can also use the following curl command. To establish the SSL connection directly with the backend, you need to reverse proxy TCP and not HTTP, and traefik doesn't (yet ?) Traefik - HomelabOS This default TLSStore should be in a namespace discoverable by Traefik. To test HTTP/3 connections, I have found the tool by Geekflare useful. Hey @jakubhajek. I have no issue with these at all. That's why you got 404. To reference a ServersTransport CRD from another namespace, The available values are: Controls whether the server's certificate chain and host name is verified. Traefik Proxy would match the requested hostname (SNI) with the certificate FQDN before using the respective certificate. More information about wildcard certificates are available in this section. I have used the ymuski/curl-http3 docker image for testing. Register the IngressRouteTCP kind in the Kubernetes cluster before creating IngressRouteTCP objects. Using Traefik for SSL passthrough (using TCP) on Kubernetes Cluster. Each will have a private key and a certificate issued by the CA for that key. When web application security is a top concern then SSL passthrough should be opted at load balancer so that an incoming security sockets layer (SSL) request is not decrypted at the load balancer rather passed along to the server for decryption as is. Thank you for taking the time to test this out. Secure Sockets Layer (SSL) is a legacy protocol, and TLS is its successor. I have also tried out setup 2. Use the configuration file shown below to quickly generate the certificate (but be sure to change the CN and DNS.1 lines to reflect your public IP). The least magical of the two options involves creating a configuration file. I'm using v2.4.8, Powered by Discourse, best viewed with JavaScript enabled.

I hope that it helps and clarifies the behavior of Traefik. Making statements based on opinion; back them up with references or personal experience. My theory about indeterminate SNI is incorrect. This is known as TLS-passthrough. I have opened an issue on GitHub. I'm running into the exact same problem now. Actually, I don't know what was the real issues you were facing. It's possible to use others key-value store providers as described here. Doing so applies the configuration to every router attached to the entrypoint (refer to the documentation to learn more). Just use the appropriate tool to validate those apps. Here is my ingress: However, if you access https://mail.devusta.com it shows self signed certificate from traefik. My current hypothesis is on how traefik handles connection reuse for http2 1 Answer. The VM is now able to use certbot/LetsEncrypt to manage its own certificates whilst having Traefik act as its reverse proxy! Terminating TLS at the point of Ingress relieves the backend service pods from the costly task of decrypting traffic and the burden of certificate management. No need to disable http2. Asking for help, clarification, or responding to other answers. As shown above, the application relies on Traefik Proxy-generated self-signed certificates the output specifies CN=TRAEFIK DEFAULT CERT. ServersTransport is the CRD implementation of a ServersTransport. Routing Configuration. In this context, specifying a namespace when referring to the resource does not make any sense, and will be ignored. This configuration allows generating Let's Encrypt certificates (thanks to HTTP-01 challenge) for the four domains local[1-4].com with described SANs. If you want to add other services - either hosted on the same host, or somewhere else on your network - to benefit from the provided convenience of . Do you extend this mTLS requirement to the backend services. Take look at the TLS options documentation for all the details. Traefik provides mutliple ways to specify its configuration: TOML. Currently when I request https url I get this: curl https://nextjs-app.dokku.arm1.localhost3002.live curl: (35) error:0A000126:SSL routines::unexpected eof while reading . Lets do this. Now that I have my YAML configuration file available (thanks to the enabled file provider), I can fill in certificates in the tls.certificates section. In this case Traefik returns 404 and in logs I see. This article assumes you have an ingress controller and applications set up. 27 Mar, 2021. Access idp first YAML. The only unanswered question left is, where does Traefik Proxy get its certificates from? Join us to learn how to secure and expose applications and services using a combination of a SaaS network control plane and a lightweight, open source agent. Thank you! Instead, we plan to implement something similar to what can be done with Nginx. A place where magic is studied and practiced? How to tell which packages are held back due to phased updates. That's why, it's better to use the onHostRule .

How to get a Docker container's IP address from the host, Docker: Copying files from Docker container to host. It's still most probably a routing issue. In the traefik configuration of the VM, I enable HTTP3 and set http3.advertisedPort to the forwarded port (this will cause traefik to listen on UDP port 443 for HTTP/3 traffic, but advertise the configured port using the Alt-Svc HTTP header instead). HTTP and HTTPS can be tested by sending a request using curl that is obvious. By continuing to browse the site you are agreeing to our use of cookies. The route can be applied to the same entrypoint and uses an IngressRouteTCP resource instead of an IngressRoute resource. OpenSSL is installed on Linux and Mac systems and is available for Windows. Use TLS with an ingress controller on Azure Kubernetes Service (AKS) There are two routers; one for TCP and another for HTTP: The TCP router requires the use of a HostSNI (SNI - Server Name Indication) entry for matching our VM host and only TCP routers require it. Accordingly, Traefik supports defining a port in two ways: Thus, in case of two sides port definition, Traefik expects a match between ports. Register the IngressRoute kind in the Kubernetes cluster before creating IngressRoute objects. There are 3 ways to configure the backend protocol for communication between Traefik and your pods: If you do not configure the above, Traefik will assume an http connection. But for Prosody (XMPP) I need to forward 5222 and 5269 directly without any HTTP routing. Learn more in this 15-minute technical walkthrough. @NEwa-05 - you rock!

And as stated above, you can configure this certificate resolver right at the entrypoint level. If you use curl, you will not encounter the error. Thanks for reminding me. Register the TLSOption kind in the Kubernetes cluster before creating TLSOption objects Such a barrier can be encountered when dealing with HTTPS and its certificates. Mail server handles his own tls servers so a tls passthrough seems logical. Specifying a namespace attribute in this case would not make any sense, and will be ignored. When specifying the default option explicitly, make sure not to specify provider namespace as the default option does not have one. If I access traefik dashboard i.e. Deploy traefik and a couple of services, some with http routers and others with tcp routers & tls passthrough using a different subdomain per service. rev2023.3.3.43278. (in the reference to the middleware) with the provider namespace, I would like to know your opinion on my setup and why it's not working and may be there's a better way to achieve end to end encryption. Ive recently started testing using traefik as a reverse proxy, for me it has a couple of compelling features: Well, because learning is a journey of multiple stages and at the moment my infrastructure also reflects this. Thank you @jakubhajek The termination process makes sure that all TLS exchange happens between the Traefik Proxy server and the end-user.

I've observed this as once the issue is replicated in one browser tab I can go to other browser tabs (under the same instance of Chrome) and try to make requests to the same domain and they will all sit there and spin. The browser displays warnings due to a self-signed certificate. When you do this, your applications remain focused on the actual solution they offer instead of also having to manage TLS certificates. @jawabuu That's unfortunate. @jbdoumenjou These values can be overridden by passing values through the command line or can be edited in the sample file values.yaml based on the type of configuration (non-SSL or SSL). In this post I will only focus on CLI commands because those can be directly used within a docker-compose.yml file. Then, I provided an email (your Lets Encrypt account), the storage file (for certificates it retrieves), and the challenge for certificate negotiation (here tlschallenge, just because its the most concise configuration option for the sake of the example). In the section above, Traefik Proxy handles TLS, But there are scenarios where your application handles it instead. @SantoDE I saw your comment here but I believe traefik could be made to work nonetheless maybe by taking into account the DNS Query as the browser seems to be setting indeterminate SNI. Might it be that AWS NLB doesn't send SNI back to targets after TLS termination?
