Traefik route53

This document is intended to be a fully working example demonstrating how to set up Traefik in Kuberneteswith the dynamic configuration coming from the IngressRoute Custom Resourceand TLS setup with Let's Encrypt. However, for the sake of simplicity, we're using k3s docker image for the Kubernetes cluster setup. And of course its internet facing IP address must match the domain name you intend to use.

In the following, the Kubernetes resources defined in YAML configuration files can be applied to the setup in two different ways:.

Our starting point is the docker-compose configuration file, to start the k3s cluster. You can start it with:. Let's now have a look in the order they should be applied, if using kubectl apply at all the required resources for the full setup.

First, the definition of the IngressRoute and the Middleware kinds. Also note the RBAC authorization resources; they'll be referenced through the serviceAccountName of the deployment, later on. Then, the services.

One for Traefik itself, and one for the app it routes for, i. Next, the deployments, i. Again, one pod for Traefik, and one for the whoami app. Now, as an exception to what we said above, please note that you should not let the ingressRoute resources below be applied automatically to your cluster.

The reason is, as soon as the ACME provider of Traefik detects we have TLS routers, it will try to generate the certificates for the corresponding domains. Therefore, for the whole thing to work, we must delay applying the ingressRoute resources until we have port-forwarding set up properly, which is the next step.

Also, and this is out of the scope if this guide, please note that because of the privileged ports limitation on Linux, the above command might fail to listen on port In which case you can use tricks such as elevating caps of kubectl with setcapsor using authbindor setting up a NAT between your host and the WAN. Look it up. Give it a few seconds for the ACME TLS challenge to complete, and you should then be able to access your whoami pod routed through Traefikfrom the outside.

Both with or just for fun, do not do that in production without TLS:. Note that you'll have to use -k as long as you're using the staging server of Let's Encrypt, since it is not an authorized certificate authority on systems where it hasn't been manually added. In the following, the Kubernetes resources defined in YAML configuration files can be applied to the setup in two different ways: the first, and usual way, is simply with the kubectl apply command.GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together.

I've been running traefik for months with no issue and randomly this popped up. Restarting traefik resolved the issue. It was 1. One day it was simply wooops your certificate is expired, I just restarted it and certificate got renewed. Hello cpuguy83 zyzop. I am currently analyzing deeply the problem and it seems to be a relied to the data storage concurrent access during the certificate renewing. OK cpuguy OK zyzopthank you. Are you using the deprecated option onDemand too?

Done months ago, actually, didn't touch configs since then. This problem is very hard to debug! I launched an environment which runs for 3 days and renews its certificates once per hour.

So far, so good Don't hesitate to migrate to this version. Moreover, I can see you use the onDemand option.

I can't because I only had the issue once and it took months to manifest. Ok cpuguyTraefik is a modern HTTP reverse proxy and load balancer made to deploy microservices with ease. NOTE: Operators will typically wish to install this component into the kube-system namespace where that namespace's default service account will ensure adequate privileges to watch Ingress resources cluster-wide.

Up until version 1. A dash and a letter were appended to Traefik's semantic version to indicate incrementally improved versions of the chart itself. For example, chart version 1.

This convention, in practice, suffered from a few problems, not the least of which was that it defied what was permitted by semver 2. This, in turn, lead to some difficulty in Helm understanding the versions of this chart. Beginning with version 1. The appVersion field in chart. After installing the chart, create DNS records for applicable domains to direct inbound traffic to the load balancer. The command removes all the Kubernetes components associated with the chart and deletes the release.

The following table lists the configurable parameters of the Traefik chart and their default values. For example:. Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. If you have already certificates stored as acme. Basic auth can be specified via dashboard.

See the linked Traefik documentation for accepted passwords encodings. It is advised to single quote passwords to avoid issues with special characters:. Next, you will need to configure the Traefik chart to use DNS challenge.

In the ACME section:. Then you need to specify the wildcard domain name in the acme. Using route53 as DNS provider requires the following configuration variables to be set:. Using gcloud as DNS provider requires the following configuration variables to be set:. In situations where Traefik lives behind an Internet-facing loadbalancer like an AWS ELB and you still want it to see the actual source IP of the visitor instead of the internal IP of the loadbalancer, you can enable the loadbalancer to use the Proxy protocol to talk to Traefik.

This effectively makes the loadbalancer transparent, as Traefik will still get the actual visitor IP address for each request. This only works if Traefik knows it's receiving traffic via the Proxy Protocol and the loadbalancer IP addresses need to be whitelisted as well.

How to set this up on AWS is described in the Kubernetes documentation hereit can easily be done by adding an annotation to the Service definition. If only one of the components either the loadbalancer or Traefik is set to use the Proxy protocol and the other is not, this will break badly as they will not be able to communicate with each other.

Traefik Traefik is a modern HTTP reverse proxy and load balancer made to deploy microservices with ease. Prerequisites Kubernetes 1. Configuration The following table lists the configurable parameters of the Traefik chart and their default values. These certificates will be use for backends calls. Memory limit per Traefik pod None rbac. See PodSecurityContext. See SecurityContext. Messages at and above the selected level will be logged. None ssl. If it's true the defaultCert and the defaultKey parameters will be ignored.

This must be used in conjunction with the secretFiles parameter to include the certs on each traefik pod pod [] ssl.Use Let's Encrypt staging server with the caServer configuration option when experimenting to avoid hitting this limit too fast. Traefik requires you to define "Certificate Resolvers" in the static configurationwhich are responsible for retrieving certificates from an ACME server.

Then, each "router" is configured to enable TLS, and is associated to a certificate resolver through the tls.

Certificates are requested for domain names retrieved from the router's dynamic configuration. Defining a certificates resolver does not result in all routers automatically using it.

Each router that is supposed to use the resolver must reference it. There are many available options for ACME. For a quick glance at what's possible, browse the configuration reference:. Certificate resolvers request certificates for a set of the domain names inferred from routers, with the following logic:. If the router has a tls.

If no tls. Please note that multiple Host matchers can be used for specifying multiple domain names for this router. When multiple domain names are inferred from a given router, only one certificate is requested with the first domain name as the main domain, and the other domains as "SANs" Subject Alternative Name. Please check the configuration examples below for more details. If there are less than 30 days remaining before the certificate expires, Traefik will attempt to renew it automatically.

Certificates that are no longer used may still be renewed, as Traefik does not currently check if the certificate is being used before renewing. When using LetsEncrypt with kubernetes, there are some known caveats with both the ingress and crd providers.

If you intend to run multiple instances of Traefik with LetsEncrypt, please ensure you read the sections on those provider pages. Do not hesitate to complete it. You can delay this operation by specifying a delay in seconds with delayBeforeCheck value must be greater than zero.

This option is useful when internal networks block external DNS queries. ACME V2 supports wildcard certificates. As described in Let's Encrypt's post wildcard certificates can only be generated through a DNS challenge.

For new sub domains which need Let's Encrypt authentication, the default Traefik certificate will be used until Traefik is restarted.If delayBeforeCheck is greater than zero, this check is delayed for the configured duration in seconds. Do not hesitate to complete it.

You can provide SANs alternative domains to each main domain. Take note that Let's Encrypt applies rate limiting. ACME V2 allows wildcard certificate support. As described in Let's Encrypt's post wildcard certificates can only be generated through a DNS challenge.

Thus, the wildcard domain has to be defined as a main domain. Most likely the root domain should receive a certificate too, so it needs to be specified as SAN and 2 DNS challenges are executed. The provider table indicates if they allow generating certificates for a wildcard domain and its root domain. If the HTTP challenge is used, acme. This is a Let's Encrypt limitation as described on the community forum.

It's a Let's Encrypt limitation as described on the community forum. This will request certificates from Let's Encrypt during the first TLS handshake for host names that do not yet have certificates. TLS handshakes are slow when requesting a host name certificate for the first time. This can lead to DoS attacks!

Enable certificate generation on frontend Host rules for frontends wired to the acme. For example, the rule Host:test1. Refer to wildcard generation for further information. See storeconfig subcommand for further information. Please use a KV Store entry instead. This kind of storage is mandatory in cluster mode. Because KV stores like Consul have limited entry size the certificates list is compressed before it is saved as KV store entry.

For example: if acme. Otherwise the backup file will be deleted when the container is stopped. This option is deprecated. Please use dnsChallenge. Entrypoint to proxy acme apply certificates to. Enable on demand certificate generation. Uncomment the line to use Let's Encrypt's staging server, leave commented to go to prod. Only domains defined here can generate wildcard certificates. Optional but recommended [acme.

Manual test with the IAM keys set in the local aws config file:. The dns-route53 TXT record s to get created and validated in the given main domain in the configuration. Saw an error about resolving the domain SOA record, see the log at the bottom.

The SOA record for the domain can definitely be retrieved, this is from inside the traefik pod itself:. It is not clear why is traefik looking for SOA of the SAN's if I'm reading the log error correctly instead of the main root domain office.

Thought I would leave an update on this in case nothing wrong with the code. I've been seeing this issue intermittently yesterday and it might had been an issue with Route53 service itself. I also tried the following JSON that didn't work either:. Just to make it clear, the office. It might be possible traefik is checking against a wrong domain during the routeGetHostedZone call.

Since we are already on this topic, do you guys have a tested and recommended IAM policy for Route53 DNS challenge to be successful? Could you take a look here I think that your permission is not set correctly. Hi mmatur I moving "routeGetChange" to the second section of my policy as in the kube-lego example you linked to did not make any difference.

The record gets inserted but the change query still fails:. After confirming manually this is really the case I raised an issue with AWS support.

I'll be back with the update. I'll close this issue, because I think the question is answered, but feel free to re-open it if necessary. It is intermittent, does not happen all the time but as you can see it happens. What can be the reason for this error? I clearly demonstrated in the case description that DNS works properly from inside the pod, i.Use Let's Encrypt staging server with the caServer configuration option when experimenting to avoid hitting this limit too fast.
