Why is the LE certificate not used for my route ? To explicitly use a different TLSOption (and using the Kubernetes Ingress resources) acme.httpChallenge.entryPoint has to be reachable by Let's Encrypt through the port 80. Exactly like @BamButz said. Traefik 2.4 adds many nice enhancements such as ProxyProtocol Support on TCP Services, Advanced support for mTLS, Initial support for Kubernetes Service API, and more than 12 enhancements from our beloved community. If Traefik requests new certificates each time it starts up, a crash-looping container can quickly reach Let's Encrypt's ratelimits. If no tls.domains option is set, Sign up for a free GitHub account to open an issue and contact its maintainers and the community. In the example above, the.

I'm still using the letsencrypt staging service since it isn't working. With the traefik.enable label, we tell Traefik to include this container in its internal configuration. Traefik Proxy is a modular router by design, allowing you to place middleware into your routes, and to modify requests before they reach their intended backend service destinations. By default, the provider verifies the TXT record before letting ACME verify. One of the benefits of using Traefik is the ability to set up automatic SSL certificates using letsencrypt, making it easier to manage SSL-encrypted websites. We tell Traefik to use the web network to route HTTP traffic to this container. For a quick glance at what's possible, browse the configuration reference: Certificate resolvers request certificates for a set of the domain names Any ideas what could it be and how to fix that? Traefik can use a default certificate for connections without a SNI, or without a matching domain. With this simple configuration in place, we have a working setup where Traefik, Lets Encrypt and Docker are working together to secure inbound traffic. Hello, I'm trying to generate new LE certificates for my domain via Traefik. I've been trying to get LetsEncrypt working with Traefik, but unfortunately I continue to get the Traefik Default Cert instead of a cert provided by LetsEncrypt's staging server. Don't close yet. To learn more, see our tips on writing great answers. In the example above, the resolver is named myresolver, and a router that uses it could look like any of the following: If you do not find any router using the certificate resolver you found in the first step, then your certificates will not be revoked. none, but run Trfik interactively & turn on, ACME certificates already generated before downtime. My cluster is a K3D cluster. Prerequisites # DNS configured, including A dedicated zone in Route53 for cluster records kubernasty. This is in response to a flaw that was discovered in the library that handles the TLS-ALPN-01 challenge. I recommend using that feature TLS - Traefik that I suggested in my previous answer.

By clicking Sign up for GitHub, you agree to our terms of service and I'd like to use my wildcard letsencrypt certificate as default. SSL Labs tests SNI and Non-SNI connection attempts to your server. I would also not expect traefik to serve its default certificate while loading the ACME certificates from a store. In order for this to work, you'll need a server with a public IP address, with Docker and docker-compose installed on it. The default option is special. https://www.paulsblog.dev, https://www.paulsblog.dev/how-to-setup-traefik-with-automatic-letsencrypt-certificate-resolver/, Activate API (with URL defined in labels) (, Certificate handling. You can delay this operation by specifying a delay (in seconds) with delayBeforeCheck (value must be greater than zero). If there is no certificate for the domain, Traefik will present the default certificate that is built-in. In the case of connecting to the IP address (10.10.20.13) of traefik, the certificate resolver is unable to resolve certificate, and I have "self-signed certificate TRAEFIK DEFAULT CERT". As described on the Let's Encrypt community forum, Under HTTPS Certificates, click Enable HTTPS. There's no reason (in production) to serve the default. It is more about customizing new commands, but always focusing on the least amount of sources for truth. Its getting the letsencrypt certificate fine and serving it but traefik keeps serving the default cert for requests not specifying a hostname. Certificates are requested for domain names retrieved from the router's dynamic configuration. There are so many tutorials I've tried but this is the best I've gotten it to work so far. storage = "acme.json" # . I checked that both my ports 80 and 443 are open and reaching the server. if the certResolver is configured, the certificate should be automatically generated for your domain. Traefik can use a default certificate for connections without a SNI, or without a matching domain. That is where the strict SNI matching may be required. Each router that is supposed to use the resolver must reference it. When using a certificate resolver that issues certificates with custom durations, one can configure the certificates' duration with the certificatesDuration option. Asking for help, clarification, or responding to other answers. I used the acme configuration from the docs: The weird thing was that /etc/traefik/acme/acme.json contained private key, though I don't know how it's supposed to work. Traefik is not creating self-signed certificate, it is already built-in into Traefik and presented in case one the valid certificate is not reachable. If this is how your Traefik Proxy is configured, then restarting the Traefik Proxy container or Deployment will force all of the certificates to renew. Also, I used docker and restarted container for couple of times without no lack. As far that I understand, you have no such functionality and there is no way to set up a "default certificate" which will point to letsencrypt, and this hack "Letsencypt as the traefik default certificate" is a single way to do that. What's your setup? The default certificate is irrelevant on that matter. There are two ways to store ACME certificates in a file from Docker: This file cannot be shared per many instances of Trfik at the same time. What did you see instead? How can I use "Default certificate" from letsencrypt? Traefik serves ONLY ONE certificate matching the host of the ingress path all the time. I want to have here (for requests to IP address) certificate from letsencrypt for mydomain.com. I don't need to add certificates manually to the acme.json. new - traefik docker compose certificatesresolvers.mytlschallenge.acme It produced this output: Serving default certificate for request: " gopinathcloud.onthewifi.com http: TLS handshake error from 24.27.84.157:39272: remote error: tls: unknown certificate My web server is (include version): In one hour after the dns records was changed, it just started to use the automatic certificate. Docker containers can only communicate with each other over TCP when they share at least one network. The "clientAuth" entrypoint is serving the "TRAEFIK DEFAULT CERT". Traefik is a popular reverse proxy and load balancer often used to manage incoming traffic to applications running in Docker containers and Kubernetes environments. Please note that multiple Host() matchers can be used) for specifying multiple domain names for this router. This is a massive shortfall in terms of usability, I'm surprised this is the suggested solution. But I get no results no matter what when I . when using the HTTP-01 challenge, certificatesresolvers.myresolver.acme.httpchallenge.entrypoint must be reachable by Let's Encrypt through port 80. Traefik is an awesome open-source tool from Containous which makes reverse proxying traffic to multiple apps easy. Conventions and notes; Core: k3s and prerequisites. It will attempt to connect via the domain name AND the IP address, which is why you get the non-match due to the IP address connections. You can provide SANs (alternative domains) to each main domain. traefik . With TLS 1.3, the cipher suites are not configurable (all supported cipher suites are safe in this case). Remove the entry corresponding to a resolver. aplsms September 9, 2021, 7:10pm 5 Powered by Discourse, best viewed with JavaScript enabled, Letsencypt as the traefik default certificate. When using a certificate resolver that issues certificates with custom durations, Do new devs get fired if they can't solve a certain bug? Now that we've fully configured and started Traefik, it's time to get our applications running! distributed Let's Encrypt, Well need to create a new static config file to hold further information on our SSL setup. They will all be reissued. In this example, we're going to use a single network called web where all containers that are handling HTTP traffic (including Traefik) will reside in. Deploy cert-manager to get a certificate for it from Let's Encrypt; Deploy inlets to expose Traefik on the Internet and expose it to the outside world; Pre-reqs. Configure wildcard certificates with traefik and let's encrypt? I may have missed something - maybe you have configured clustering with KV storage etc - but I don't see it in the info you've provided so far. and the connection will fail if there is no mutually supported protocol. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. Many lego environment variables can be overridden by their respective _FILE counterpart, which should have a filepath to a file that contains the secret as its value. you must specify the provider namespace, for example: The TLS options allow one to configure some parameters of the TLS connection. Certificates that are no longer used may still be renewed, as Traefik does not currently check if the certificate is being used before renewing. I need to point the default certificate to the certificate in acme.json. Notice how there isn't a single container that has any published ports to the host -- everything is routed through Docker networks. You can configure Traefik to use an ACME provider (like Let's Encrypt) to generate the default certificate. I switched to ha proxy briefly, will be trying the strict tls option soon. Both through the same domain and different port. Traefik supports mutual authentication, through the clientAuth section. privacy statement. it is correctly resolved for any domain like myhost.mydomain.com. I ran into this in my traefik setup as well. Where does this (supposedly) Gibson quote come from? Uncomment the line to run on the staging Let's Encrypt server. Use the TLS-ALPN-01 challenge to generate and renew ACME certificates by provisioning a TLS certificate. If HTTP-01 challenge is used, acme.httpChallenge.entryPoint has to be defined and reachable by Let's Encrypt through the port 80. Already on GitHub? Deployment, Service and IngressRoute for whoami app : When I reach localhost/whoami from the browser, I can see the whoami app but the used certificate is the default cert from Traefik. sudo nano letsencrypt-issuer.yml. Use the DNS-01 challenge to generate and renew ACME certificates by provisioning a DNS record. It terminates TLS connections and then routes to various containers based on Host rules. Thanks a lot! Then it should be safe to fall back to automatic certificates. create a file on your host and mount it as a volume: mount the folder containing the file as a volume. It is not a good practice because this pod becomes asingle point of failure in your infrastructure. 1. Traefik should not serve TRAEFIK DEFAULT CERT when there is a matching custom cert, HAPROXY SSL Server Test: sample-custom-dc2.widemeshstaging.net (Powered by Qualys SSL Labs).pdf, https://docs.traefik.io/v1.7/configuration/entrypoints/#default-certificate, https://docs.traefik.io/v1.7/configuration/entrypoints/#strict-sni-checking, TLS Option VersionTLS12 denies TLS1.1 but still allows TLS1.0, traefik DEFAULT CERTIFICATE is served on slack.moov.io, option to disable the DEFAULT CERTIFICATE. I posted the question on the Traefik forums as well, and somebody there suggested that I should use dnsChallenge instead of httpChallenge. During Trfik configuration migration from a configuration file to a KV store (thanks to storeconfig subcommand as described here), if ACME certificates have to be migrated too, use both storageFile and storage. For authentication policies that require verification of the client certificate, the certificate authority for the certificate should be set in clientAuth.caFiles. Update the configuration labels as follows: Adding tls.domains is optional (per the Traefik docs) if its not set, the certificate resolvers will fall back to using the provided routers rule and attempt to provision the domain listed there. Essentially, this is the actual rule used for Layer-7 load balancing. Acknowledge that your machine names and your tailnet name will be published on a public ledger. , The Global API Key needs to be used, not the Origin CA Key. We discourage the use of this setting to disable TLS1.3. This option allows to specify the list of supported application level protocols for the TLS handshake, Useful if internal networks block external DNS queries. Enable certificate generation on frontends Host rules (for frontends wired on the acme.entryPoint). However, as APIS have been upgraded and enhanced, the operation of obtaining certificates with the acme.sh script has become more and more difficult. I have a deployment for my workload served by an ingress with a custom Let's Encrypt certificate I added manually to the kubernetes cluster. https://github.com/containous/traefik/blob/4e9166759dca1a2e7bdba1780c6a08b655d20522/pkg/tls/certificate_store_test.go#L17, https://github.com/containous/traefik/blob/e378cb410c4ce1f0d25be64f1e963d42e1c7c004/integration/https_test.go#L298-L301, https://github.com/containous/traefik/blob/e378cb410c4ce1f0d25be64f1e963d42e1c7c004/integration/https_test.go#L334-L337. For example, CF_API_EMAIL_FILE=/run/secrets/traefik_cf-api-email could be used to provide a Cloudflare API email address as a Docker secret named traefik_cf-api-email. For example, a rule Host:test1.traefik.io,test2.traefik.io will request a certificate with main domain test1.traefik.io and SAN test2.traefik.io. Defining a certificate resolver does not result in all routers automatically using it. or don't match any of the configured certificates. Docker compose file for Traefik: By default, if a non-SNI request is sent to Traefik, and it cannot find a matching certificate (with an IP SAN), it will return the default certificate, which is usually self signed. If you use Traefik Enterprise v1 please get in touch with support directly and we will happily help you make the necessary changes to your environment. If you intend to run multiple instances of Traefik with LetsEncrypt, please ensure you read the sections on those provider pages. To confirm that its created and running, enter: You should see a list of all containers and the process status (Ive hidden the non-relevant ones): To confirm that the proxy is working as expected, visithttp://localhost:8080/api/rawdatato see the config. (commit). The recommended approach is to update the clients to support TLS1.3. I've got a LB and some requests without hostnames in my setup that I didn't want to change to fix this issue. You should create certificateResolver based on the examples we have in our documentation: Let's Encrypt - Traefik. This will request a certificate from Let's Encrypt during the first TLS handshake for a host name that does not yet have a certificate.
