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. I recommend using that feature TLS - Traefik that I suggested in my previous answer. I'll post an excerpt of my Traefik logs and my configuration files. Also, we're mounting the /var/run/docker.sock Docker socket in the container as well, so Traefik can listen to Docker events and reconfigure its own internal configuration when containers are created (or shut down). and the connection will fail if there is no mutually supported protocol. 2. I think there's a chance Traefik might be returning the certificates in the wrong order randomly, so in some requests it sometimes returns the matching SNI certificate first and then the default while some other times it returns the default certificate first and then the matching certificate SNI second. if the certResolver is configured, the certificate should be automatically generated for your domain. Docker containers can only communicate with each other over TCP when they share at least one network. The clientAuth.clientAuthType option governs the behaviour as follows: If you are using Traefik for commercial applications, 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. Using Kolmogorov complexity to measure difficulty of problems? Its getting the letsencrypt certificate fine and serving it but traefik keeps serving the default cert for requests not specifying a hostname. Traefik v2 support: to be able to use the defaultCertificate option EDIT: Check if the static configuration contains certificate resolvers using the TLS-ALPN-01 challenge. The text was updated successfully, but these errors were encountered: This is HAPROXY Controller serving the exact same ingresses: 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. acme.httpChallenge.entryPoint has to be reachable by Let's Encrypt through the port 80. If you do not find any certificate resolvers with tlsChallenge in their configuration, then your certificates will not be revoked. The default option is special. Styling contours by colour and by line thickness in QGIS, Linear Algebra - Linear transformation question. A copy of this certificate is included automatically in those OCSP responses, so Subscribers don't need to do anything with it. Traefik Enterprise should automatically obtain the new certificate. https://docs.traefik.io/v1.7/configuration/entrypoints/#default-certificate, Configure Strict SNI checking so that no connection can be made without a matching certificate: Traefik can use a default certificate for connections without a SNI, or without a matching domain. You can use it as your: Traefik Enterprise enables centralized access management, From the /opt/traefik directory, run docker-compose up -d which will create and start the Traefik container. I ran into this in my traefik setup as well. @aplsms do you have any update/workaround? In the example, two segment names are defined : basic and admin. rev2023.3.3.43278. However, frequently, I will refer you back to my previous guides for some reading to not make this guide too lengthy. Uncomment the line to run on the staging Let's Encrypt server. 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.

As mentioned earlier, we don't want containers exposed automatically by Traefik. We use Traefik to power some of our edge SSL solution here at Qloaked, but if youre trying to figure out how to set up a secure reverse proxy and you DONT want to use Qloaked, heres a simple guide to get you started. This field has no sense if a provider is not defined. I'm using letsencrypt as the main certificate resolver. Instead of an automatic Let's encrypt certificate, traefik had used the default certificate. If you have to use Trfik cluster mode, please use a KV Store entry. For authentication policies that require verification of the client certificate, the certificate authority for the certificate should be set in clientAuth.caFiles. As described in Let's Encrypt's post wildcard certificates can only be generated through a DNS-01 challenge. Use the TLS-ALPN-01 challenge to generate and renew ACME certificates by provisioning a TLS certificate. in this way, I need to restart traefik every time when a certificate is updated. These instructions assume that you are using the default certificate store named acme.json. Making statements based on opinion; back them up with references or personal experience. We do by creating a TLSStore configuration and setting the defaultCertificate key to the secret that contains the certificate. If the valid configuration with certResover exists Traefik will try to issue certificates from LetsEncrypt. You can configure Traefik to use an ACME provider (like Let's Encrypt) to generate the default certificate. To achieve that, you'll have to create a TLSOption resource with the name default. Use custom DNS servers to resolve the FQDN authority. 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. , As explained in the LEGO hurricane configuration, each domain or wildcard (record name) needs a token. The HTTP-01 challenge used to work for me before and I haven't touched my configs in months I believe, so . I want to run Dokku container behind Trefik, I also expose other services with same Traefik instance directly without Dokku. This all works fine. sudo nano letsencrypt-issuer.yml. You would also notice that we have a "dummy" container. Now that weve got the proxy and the endpoint working, were going to secure the traffic. To add / remove TLS certificates, even when Traefik is already running, their definition can be added to the dynamic configuration, in the [[tls.certificates]] section: In the above example, we've used the file provider to handle these definitions. The Let's Encrypt issued certificate when connecting to the "https" and "clientAuth" entrypoint. Where does this (supposedly) Gibson quote come from? When using a certificate resolver that issues certificates with custom durations, If acme.json is not saved on a persistent volume (Docker volume, Kubernetes PersistentVolume, etc), then when Traefik Proxy starts, no acme.json file is present. I have to close this one because of its lack of activity . Trigger a reload of the dynamic configuration to make the change effective. when using the TLS-ALPN-01 challenge, Traefik must be reachable by Let's Encrypt through port 443. The other 3 servers are going to respond with the default certificate, because they have no idea about the certificate issuance request initiated by that 1 other Traefik instance.

I haven't made an updates in configuration. Specifying tls.domains on each router seems to have solved the issue by prioritizing the custom certificate instead of the default certificate. As a result, Traefik Proxy goes through your certificate list to find a suitable match for the domain at hand if not, it uses a default certificate. Use DNS-01 challenge to generate/renew ACME certificates. Defining one ACME challenge is a requirement for a certificate resolver to be functional. Note that Let's Encrypt API has rate limiting. Let's take a simple example of a micro-service project consisting of various services, where some will be exposed to the outside world and some will not. With the traefik.enable label, we tell Traefik to include this container in its internal configuration. Can confirm the same is happening when using traefik from docker-compose directly with ACME. I switched to ha proxy briefly, will be trying the strict tls option soon. If you are using Traefik for commercial applications, Hey @aplsms; I am referring to the last question I asked. TLS handshakes will be slow when requesting a host name certificate for the first time, this can lead to DoS attacks. Enable MagicDNS if not already enabled for your tailnet. when experimenting to avoid hitting this limit too fast. Under HTTPS Certificates, click Enable HTTPS. Created a letsencrypt wildcard cert for *.kube.mydomain.com (confirmed in certificate transparency logs that it is valid) What did you see instead? The default certificate is irrelevant on that matter. We have Traefik on a network named "traefik". If Let's Encrypt is not reachable, these certificates will be used : Default Trfik certificate will be used instead of ACME certificates for new (sub)domains (which need Let's Encrypt challenge). Since the traefik container we've created and started earlier is also attached to this network, HTTP requests can now get routed to these containers. The last step is exporting the needed variables and running the docker-compose.yml: The commands above will now create two new subdomains (https://dashboard.yourdomain.de and https://whoami.yourdomain.de) which also uses an SSL certificate provided by Lets Encrypt, I hope this article gave you a quick and neat overview of how to set up traefik. apiVersion: traefik.containo.us/v1alpha1 kind: TLSStore metadata: name: default namespace: default spec: defaultCertificate: secretName: whoami-secret Save that as default-tls-store.yml and deploy it.

Also, we're making sure the container is automatically restarted by the Docker engine in case of problems (or: if the server is rebooted). It would be nice to have an option to disable the DEFAULT CERTIFICATE and error/warn in cases where no certificate is usable for a route. This will remove all the certificates for that resolver. Essentially, this is the actual rule used for Layer-7 load balancing. This option is useful when internal networks block external DNS queries. My cluster is a K3D cluster. Please let us know if that resolves your issue. However, as APIS have been upgraded and enhanced, the operation of obtaining certificates with the acme.sh script has become more and more difficult. then the certificate resolver uses the router's rule, If you have any questions about the process, or if you encounter any problems performing the updates, please reach out to Traefik Labs Support (for Traefik Enterprise customers) or post on the Community Forum (for Traefik Proxy users).

In my traefik/letsencrypt setup which worked fine for quite some time traefik without any changes started returning traefik default certificate. You can use it as your: Traefik Enterprise enables centralized access management, I try to setup Traefik to get certificates from Let's Encrypt using DNS challenge and secure a whoami app with this certificate. So each update of record name must be followed by an update of the HURRICANE_TOKENS variable, and a restart of Traefik. The TLS options allow one to configure some parameters of the TLS connection. Of course, if youre not into a roll-your-own solution, you could use Qloakeds pre-configured SSL at the edge services. To configure Traefik LetsEncrypt , navigate to cert manager acme ingress page, go to Configure Let's Encrypt Issuer, copy the let's encrypt issuer yml and change as shown below. 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. This kind of storage is mandatory in cluster mode. Finally but not unimportantly, we tell Traefik to route to port 9000, since that is the actual TCP/IP port the container actually listens on. it is correctly resolved for any domain like myhost.mydomain.com. Learn more in this 15-minute technical walkthrough. (commit). Cipher suites defined for TLS 1.2 and below cannot be used in TLS 1.3, and vice versa.

These are Let's Encrypt limitations as described on the community forum. certificate properly obtained from letsencrypt and stored by traefik. whoami: # A container that exposes an API to show its IP address image: containous/whoami labels: - traefik.http.routers.whoami.rule=Host('yourdomain.org') #sets the rule for the router - traefik.http.routers.whoami.tls=true #sets the service to use TLS - traefik.http.routers.whoami.tls.certresolver=letsEncrypt #references our . Edit acme.json to remove all certificates linked to the certificate resolver (or resolvers) identified in the earlier steps. Well need to create a new static config file to hold further information on our SSL setup. one can configure the certificates' duration with the certificatesDuration option. With this simple configuration in place, we have a working setup where Traefik, Lets Encrypt and Docker are working together to secure inbound traffic. We're publishing the default HTTP ports 80 and 443 on the host, and making sure the container is placed within the web network we've created earlier on.

Please verify your certificate resolver configuration, if it is correctly set up Traefik will try to connect LetsEncrypt server and issue the certificate. I deploy Traefik v2 from the official Helm Chart : helm install traefik traefik/traefik -f traefik-values.yaml. Certificates that have been removed will be reissued when Traefik restarts, within the constraints of the Lets Encrypt rate limits. Traefik is an awesome open-source tool from Containous which makes reverse proxying traffic to multiple apps easy. If you do not want to remove all certificates, then carefully edit the resolver entry to remove only certificates that will be revoked. How to tell which packages are held back due to phased updates. See also Let's Encrypt examples and Docker & Let's Encrypt user guide.
