I need you to confirm if are you able to reproduce the results as detailed in the bug report. Forwarding TCP traffic from Traefik to a Docker container Sometimes your services handle TLS by themselves. Just confirmed that this happens even with the firefox browser. Kindly share your result when accessing https://idp.${DOMAIN}/healthz Is there a proper earth ground point in this switch box? Proxy protocol is enabled to make sure that the VMs receive the right client IP addresses. Conversely, for cross-provider references, for example, when referencing the file provider from a docker label, you must specify the . Many thanks for your patience. Does ZnSO4 + H2 at high pressure reverses to Zn + H2SO4? Developer trials in a modern London startup Balancing legacy code with new technology, Easy and dynamic discovery of services via docker labels. @jbdoumenjou When I enable debug logging on the Traefik side I see no log events until that timeout seems to expire and the expected debug events all show up at once. HTTP/3 is running on the VM. This is the only relevant section that we should use for testing. URI used to match against SAN URIs during the server's certificate verification. No configuration is needed for traefik on the host system. Traefik CRDs are building blocks that you can assemble according to your needs. Most of the solutions I have seen, and they make sense, are to disable https on the container, but I can't do that because I'm trying to replicate as close to production as posible. This all without needing to change my config above. Additionally, when you want to reference a MiddlewareTCP from the CRD Provider, I assume that with TLS passthrough Traefik should not decrypt anything.. Only when I change Traefik target group to TCP - things are working, but communication between AWS NLB and Traefik is not encrypted. If I start chrome with http2 disabled, I can access both. Is there any important aspect that I am missing? Try using a browser and share your results. Use it as a dry run for a business site before committing to a year of hosting payments. You can use a home server to serve content to hosted sites. Difficulties with estimation of epsilon-delta limit proof. We do by creating a TLSStore configuration and setting the defaultCertificate key to the secret that contains the certificate. TCP services are not HTTP, so netcat is the right tool to test it or openssl with piping message to session, see the examples above how I tested Whoami application. First, lets expose the my-app service on HTTP so that it handles requests on the domain example.com. The below configuration defines a TLSOption resource with specific TLS and applies it to the whoami IngressRoute. Thanks @jakubhajek and there is a second level because each whoami service is a replicaset and is thus handled as a load-balancer of servers. How is Docker different from a virtual machine? To learn more, see our tips on writing great answers. UDP does not support SNI - please learn more from our documentation. This is known as TLS-passthrough. We just need any TLS passthrough service and a HTTP service using port 443. 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. My current hypothesis is on how traefik handles connection reuse for http2 What am I doing wrong here in the PlotLegends specification? The backend needs to receive https requests. This configuration allows generating Let's Encrypt certificates (thanks to HTTP-01 challenge) for the four domains local[1-4].com with described SANs. When dealing with an HTTPS route, Traefik Proxy goes through your default certificate store to find a matching certificate. It works out-of-the-box with Let's Encrypt, taking care of all TLS certificate management. By clicking Sign up for GitHub, you agree to our terms of service and So in the end all apps run on https, some on their own, and some are handled by my Traefik. The tcp router is not accessible via browser but works with curl. This configuration allows generating a Let's Encrypt certificate (thanks to HTTP-01 challenge) during the first HTTPS request on a new domain. 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. OpenSSL is installed on Linux and Mac systems and is available for Windows. My Traefik instance (s) is running . That's why you have to reach the service by specifying the port. Before I jump in, lets have a look at a few prerequisites. The first component of this architecture is Traefik, a reverse proxy. with curl: assuming 10.42.0.6 is the IP address of one of the replicas (a pod then) of the whoami1 service. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Mailcow "backend" has the one generated w/ letsencrypt, meaning port forwards are well configured. We would like to be able to set the client TLS cert into a specific header forwarded to the backend server. In any case, I thought this should be noted as there may be an underlying issue as @ReillyTevera noted. Thank you @jakubhajek You can find the whoami.yaml file here. The certificatesresolvers specify details about the Let's Encrypt account, Let's Encrypt challenge, Let's Encrypt servers, and the certificate storage. The CA secret must contain a base64 encoded certificate under either a tls.ca or a ca.crt key. Would you please share a snippet of code that contains only one service that is causing the issue? Traefik provides mutliple ways to specify its configuration: TOML. When using browser e.g. Not the answer you're looking for? As Kubernetes also has its own notion of namespace, one should not confuse the kubernetes namespace of a resource TLSStore is the CRD implementation of a Traefik "TLS Store". This option simplifies the configuration but : That's why, it's better to use the onHostRule option if possible. - "--entryPoints.web.forwardedHeaders.insecure=true", - "--entryPoints.websecure.forwardedHeaders.insecure=true", - "--providers.docker.exposedbydefault=false", - "--providers.docker.endpoint=unix:///var/run/docker.sock", - "--providers.file.directory=/etc/traefik", - "--providers.kubernetesIngress.ingressClass=traefik-cert-manager", - "--entrypoints.web.http.redirections.entrypoint.to=websecure", - "--entrypoints.web.http.redirections.entrypoint.scheme=https", - "--serverstransport.insecureskipverify=true", - "traefik.http.routers.traefik.service=api@internal", - "traefik.http.routers.traefik.rule=Host(`dash.${DOMAIN}`)", - "traefik.http.routers.traefik.entrypoints=web,websecure", - "traefik.http.services.traefik.loadbalancer.server.port=8080", - /var/run/docker.sock:/var/run/docker.sock, hash: "$2a$10$2b2cU8CPhOTaGrs1HRQuAueS7JTT5ZHsHSzYiFPm1leZck7Mc8T4W", userID: "08a8684b-db88-4b73-90a9-3cd1661f5466", - "traefik.http.routers.whoami.entrypoints=web,websecure", - "traefik.http.routers.whoami.rule=Host(`whoami.${DOMAIN}`)", - "traefik.tcp.routers.whoamitcp.entrypoints=tcp", - "traefik.tcp.routers.whoamitcp.tls=true", - "traefik.tcp.routers.whoamitcp.rule=HostSNI(`whotcp.${DOMAIN}`)", - "traefik.udp.routers.whoamiudp.entrypoints=udp", - "traefik.udp.services.whoamiudp.loadbalancer.server.port=8080", test: wget -qO- -t1 localhost/healthz || exit 1, - "traefik.http.routers.dex.entrypoints=web,websecure", - "traefik.http.routers.dex.rule=Host(`dex.${DOMAIN}`)", - "traefik.http.services.dex.loadbalancer.server.port=80", - "traefik.tcp.routers.dex-tcp.rule=HostSNI(`idp.${DOMAIN}`)", - "traefik.tcp.routers.dex-tcp.entrypoints=websecure", - "traefik.tcp.routers.dex-tcp.tls.passthrough=true", - "traefik.tcp.services.dex-tcp.loadbalancer.server.port=443", command: ["--issuer-root-ca=/etc/dex/certs/rootca.pem","--debug","--listen=http://dex-app:6555","--redirect-uri=https://app.local.dev/callback","--issuer=https://dex.local.dev"], - "traefik.http.routers.dex-app.entrypoints=web,websecure", - "traefik.http.routers.dex-app.rule=Host(`app.${DOMAIN}`)", - "traefik.http.routers.dex-app.tls=true", /var/run/docker.sock:/var/run/docker.sock, wget -qO- -t1 localhost/healthz || exit 1, ["--issuer-root-ca=/etc/dex/certs/rootca.pem", "--debug", "--listen=http://dex-app:6555", "--redirect-uri=https://app.127.0.0.1.nip.io/callback", "--issuer=https://dex.127.0.0.1.nip.io"], tiangolo/full-stack-fastapi-postgresql#353. # Dynamic configuration tls: options: require-mtls: clientAuth: clientAuthType: RequireAndVerifyClientCert caFiles: - /certs/rootCA.crt. Traefik Proxy provides several options to control and configure the different aspects of the TLS handshake. See the Traefik Proxy documentation to learn more. A collection of contributions around Traefik can be found at https://awesome.traefik.io. A centralized routing solution for your Kubernetes deployment, Powerful traffic management for your Docker Swarm deployment, Act as a single entry point for microservices deployments, Create a Secured Gateway to Your Applications with Traefik Hub. Register the TraefikService kind in the Kubernetes cluster before creating TraefikService objects, To avoid confusion, lets state the obvious I havent yet configured anything but enabled requests on 443 to be handled by Traefik Proxy. Does ZnSO4 + H2 at high pressure reverses to Zn + H2SO4? If so, please share the results so we can investigate further. Hey @jakubhajek. Create the following folder structure. You can find an exhaustive list, generated from Traefik's source code, of the custom resources and their attributes in. Reload the application in the browser, and view the certificate details. But if needed, you can customize the default certificate like so: Even though the configuration is straightforward, it is your responsibility, as the administrator, to configure/renew your certificates when they expire. The browser displays warnings due to a self-signed certificate. I have also tried out setup 2. 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). Defines the set of root certificate authorities to use when verifying server certificates. To avoid hitting rate limits or being banned from Let's Encrypt, we recommend that you use the acme-staging server for all non-production environments. Later on, youll be able to use one or the other on your routers. Thank you for taking the time to test this out. It is true for HTTP, TCP, and UDP Whoami service. Jul 18, 2020. The difference between the phonemes /p/ and /b/ in Japanese, Minimising the environmental effects of my dyson brain. Traefik Proxy 2.x and TLS 101 https://idp.${DOMAIN}/healthz is reachable via browser. Response depends on which router I access first while Firefox, curl & http/1 work just fine. #7776 UDP service is connectionless and I personall use netcat to test that kind of dervice. envoy needs discovery through KV stores / APIs (sorry, I don't know it very well). By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. I have opened an issue on GitHub. That association happens with the tls.certResolver key, as seen below: Make that change, and then deploy the updated IngressRoute configuration. when the definition of the middleware comes from another provider. To configure this passthrough, you need to configure a TCP router, even if your service handles HTTPS. 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, One can use, list of names of the referenced Kubernetes. Bug. As Kubernetes also has its own notion of namespace, one should not confuse the kubernetes namespace of a resource More information about available middlewares in the dedicated middlewares section. What video game is Charlie playing in Poker Face S01E07? If not, its time to read Traefik 2 & Docker 101. This means that you cannot have two stores that are named default in different Kubernetes namespaces. Deploy the updated configuration and then revisit SSLLabs and regenerate the report. Might it be that AWS NLB doesn't send SNI back to targets after TLS termination? Easy and dynamic discovery of services via docker labels I don't need to update my base docker image to include and manage certbot when I add a new service, I just update a few docker labels on my service. I tried the traefik.frontend.passTLSCert=true option but getting "404 page not found" error when I access my web app and also get this error on Traefik container. 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).
