GitHub - traefik/traefik: The Cloud Native Application Proxy It turns out Chrome supports HTTP/3 only on ports < 1024. Deploy the updated configuration and then revisit SSLLabs and regenerate the report. Traefik Proxy would match the requested hostname (SNI) with the certificate FQDN before using the respective certificate. In the section above, Traefik Proxy handles TLS, But there are scenarios where your application handles it instead. If you are comfortable building your own Traefik image you can test to see if my issue is related to yours by checking out the 2.4 branch, adding http2.ConfigureServer(serverHTTP, nil) at line 503 of server_entrypoint_tcp.go, recompiling, and then trying the new image/binary. You can't use any standard Traefik TLS offloading due to the differences in how Traefik and Prosidy handle TLS. Handle both http and https with a single Traefik config No need to disable http2. When dealing with an HTTPS route, Traefik Proxy goes through your default certificate store to find a matching certificate. If no serversTransport is specified, the [emailprotected] will be used. As the field name can reference different types of objects, use the field kind to avoid any ambiguity. Hey @ReillyTevera I observed this in Chrome and Microsoft Edge. You can find the whoami.yaml file here. That's why you have to reach the service by specifying the port. bbratchiv April 16, 2021, 9:18am #1. This means that you cannot have two stores that are named default in .

If you use TLS (even with a passthrough) in your configuration router, you need to use TLS. To learn more, see our tips on writing great answers. Since it is used by default on IngressRoute and IngressRouteTCP objects, there never is a need to actually reference it. I got this partly to work, with the following findings: Due to the restriction of Chrome and other tools that HTTP/3 needs to run on port 443, it seems that setup 2 is not suitable for production. Have a question about this project? My plan is to use docker for all my future services to make the most of my limited hardware but I still have existing services that are Virtual Machines (also known as a VM or VMs). Here I chose to add plain old configuration files (--providers.file) to the configuration/ directory and I automatically reload changes with --providers.file.watch=true. I have restarted and even stoped/stared trafik container . Config update issues with docker-compose and tcp and tls passthrough Yes, especially if they dont involve real-life, practical situations.

However Traefik keeps serving it own self-generated certificate. The certificatesresolvers specify details about the Let's Encrypt account, Let's Encrypt challenge, Let's Encrypt servers, and the certificate storage. This means that no proxy protocol needed, but it also means that in the future I will have to always test the setup 4 times, over IPv4/IPv6 and over HTTP/2/3, as in each scenario the packages will take a different route. Defines the set of root certificate authorities to use when verifying server certificates. The polished configuration options ensure that configuring Traefik is always achieved the same way whether expressed with TOML, YAML, labels, or keys, and the revamped documentation includes examples for every syntax. Instant delete: You can wipe a site as fast as deleting a directory. The above report shows that the whoami service supports TLS 1.0 and 1.1 protocols without forward secrecy key exchange algorithms.

Connect and share knowledge within a single location that is structured and easy to search. First, lets expose the my-app service on HTTP so that it handles requests on the domain example.com. Note that we can either give path to certificate file or directly the file content itself (like in this TOML example). # Dynamic configuration tls: options: require-mtls: clientAuth: clientAuthType: RequireAndVerifyClientCert caFiles: - /certs/rootCA.crt. and other advanced capabilities. When you do this, your applications remain focused on the actual solution they offer instead of also having to manage TLS certificates. rev2023.3.3.43278. General.

You can't use any standard Traefik TLS offloading due to the differences in how Traefik and Prosidy handle TLS. @jspdown @ldez As Kubernetes also has its own notion of namespace, one should not confuse the kubernetes namespace of a resource When you have certificates that come from a provider other than Let's Encrypt (either self-signed, from an internal CA, or from another commercial CA), you can apply these certificates manually and instruct Traefik to use them. Powered by Discourse, best viewed with JavaScript enabled, HTTP/3 is running on the host system. Traefik Proxy covers that and more. The passthrough configuration needs a TCP route . I currently have a Traefik instance that's being run using the following. For TCP and UDP Services use e.g.OpenSSL and Netcat.

You can generate the self-signed certificate pair in a non-interactive manner using the following command: Before we can update the IngressRoute to use the certificates, the certificate and key pair must be uploaded as a Kubernetes Secret with the following two attributes: Create the Secret, using the following command: Update the IngressRoute and reference the Secret in the tls.secretName attribute. The correct SNI is always sent by the browser Luckily for us and for you, of course Traefik Proxy lowers this kind of hurdle and makes sure that there are easy ways to connect your projects to the outside world securely. dex-app-2.txt Deploy traefik and a couple of services, some with http routers and others with tcp routers & tls passthrough using a different subdomain per service. I have used the ymuski/curl-http3 docker image for testing. You can define TLS termination separately on each router, configure TLS passthrough, use the new CertResolver to benefit from . Could you suggest any solution? I couldn't see anything in the Traefik documentation on putting the entrypoint itself into TCP mode instead of HTTP mode. The host system has one UDP port forward configured for each VM. Hello, I have a question regarding Traefik TLS passthrough functionality and TCP entrypoint. HTTPS on Kubernetes using Traefik Proxy | Traefik Labs Health check passed in 91.5s%, printf "GET /healthz HTTP/1.1\r\nHost: localhost\r\n\r\n" |openssl s_client -connect idp.127.0.0.1.nip.io:8800 -CAfile traefik/certs/rootca.pem -quiet, And here are the logs from that app. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. kubernetes - what is the disadvantage using hostSNI(*) in traefik TCP Incorrect Routing for mixed HTTP routers & TCP (TLS Passthrough Later on, youll be able to use one or the other on your routers.

For instance, in the example below, there is a first level of load-balancing because there is a (Weighted Round Robin) load-balancing of the two whoami services, Using Traefik with TLS on Kubernetes | by Patrick Easters | Medium 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 . Please have a look at the UDP routers, Host SNI is not needed, because basically speaking UDP does not have SNI. Make sure you use a new window session and access the pages in the order I described. corresponds to the deadline that the proxy sets, after one of its connected peers indicates it has closed the writing capability of its connection, to close the reading capability as well, hence fully terminating the connection. @jakubhajek Is there an avenue available where we can have a live chat? If there are missing use cases or still unanswered questions, let me know in the comments or on our community forum!
