Traefik 2 middleware

It mostly works as expected, but you will have to define static rules that point to the docker gateway probably For security I even put double authentication with OAuth from google.

If it is a different service that does not run under docker, like for me my OMV which is physical I use an additional conf file or I define the service:. Regarding the access problem I am sure it is related to the number of requests you made for nextcloud because each time you access the URL in https it makes a certificate request at LE. You just have to wait or test for another service. I do not regret having tried. Maybe I can try your method. Register yourself now and be a part of our community!

Dashboard Forum Installation Docker. Hi all, I'm currently using LE with Docker and reverse proxy. I'm interest to try out Traefik, it's seem useful for load balancing and reverse proxy.

Has anybody in here currently using it and would like to share their knowledge? I did some researches today, and it seem a lot of work. I already have a domain, and have a lot of services running like Grafana, NC, Prometheus There seem a lack of documentation for Traefik for those software. I got Traefik container running, but can't get Nextcloud container to run.

Got error from Traefik container: Code. Still can't access Nextcloud, same error. As far as I'm concerned, I set it up more than a month ago. I haven't figured it all out yet but it's great.

No more bothering with certificates for all the applications you publish: D For security I even put double authentication with OAuth from google. Hello Methy, Thanks for the quick reply.

I'm just try to access my containers like Nextcloud, Grafana. So far, I can't access Nextcloud. Error: I can show you my docker-composed of my Portainer and Traefik containers : Code. To allow access via Traefik from outside.Attached to the routers, pieces of middleware are a means of tweaking the requests before they are sent to your service or before the answer from the services are sent to the clients.

There are several available middleware in Traefik, some can modify the request, the headers, some are in charge of redirections, some add authentication, and so on. When you declare a middleware, it lives in its provider's namespace. For example, if you declare a middleware using a Docker label, under the hoods, it will reside in the docker provider namespace. If you use multiple providers and wish to reference a middleware declared in another provider aka referencing a cross-provider middlewarethen you'll have to append to the middleware name, the separator, followed by the provider name.

As Kubernetes also has its own notion of namespace, one should not confuse the "provider namespace" with the "kubernetes namespace" of a resource when in the context of a cross-provider usage.

In this case, since the definition of the middleware is not in kubernetes, specifying a "kubernetes namespace" when referring to the resource does not make any sense, and therefore this specification would be ignored even if present. Pieces of middleware can be combined in chains to fit every scenario.

Kubernetes Namespace As Kubernetes also has its own notion of namespace, one should not confuse the "provider namespace" with the "kubernetes namespace" of a resource when in the context of a cross-provider usage.

Referencing a Middleware from Another Provider Declaring the add-foo-prefix in the file provider. File TOML [http.These services are mostly running from containers with a reverse proxy to expose them to the web. I leave this task to Traefik. Before that I used a popular triad of nginxdocker-gen and letsencrypt-nginx-proxy-companion.

This for the most part worked great but three services for one task also meant three sources for possible errors. Around this time last year I learned about Traefik with its single binary approach and general small footprint. After following a guide by Keith Thompson I jumped ships.

This fall containous the company behind Traefik released version 2. This is a major release including cool stuff like reusable middlewaresa new fun web dashboard and advanced stuff for production deployments like canary deployments.

This changes come with a trade off. The new version has lots of breaking changes because of that I had to update my deployment and understand the new paradigms introduced. In this post I want to help share my findings and show a path to upgrade from 1. Before we go further, we are setting up a small Docker based environment in Traefik 1.

The setup is quite simple and can be described as follows: Of course you need to use your own subdomains. I created a repository at GitHub that follows our upgrade steps. You can take a look at the initial situation in this commit. Before we upgrade this setup we need to understand some key differences between Traefik v1. Especially against the backdrop of our planned upgrade, these concepts can be considered as follows:.

The great part about middlewares is that they can be reused. For instance a scheme redirection from http to https can be defined once and used again all over the setup by just adding it to a router. Please check out the documentation for more background on these new concepts.

We will start of by focusing on the basic setup and enabling dashboard. Begin by stopping your 1. Like before Traefik uses a static and a dynamic configuration.

The first are set during startup. The later are fully dynamic and can change while Traefik is running. Of course this is a purely subjective decision on my part. Both files need to be mounted in our docker-compose.

Now we can start reworking our static configuration traefik. The Entrypoint definition will be part of our dynamic configuration as part of a router. First up: In v2 the format of the acme. This file needs to be converted from v1 to v2. For this task containous released the traefik-migration-tool.

Run it from your working directory:.Releases keep coming, but this one feels unique to us because this is our very first release since Traefik 2. We all know it, you all know it: Traefik 2. Thanks to the immense feedback we got from the community, we know we can do even better, and we were given some pointers in the right direction.

But before we talk about what we've learned and how we'll leverage this knowledge, let's talk about the changes introduced in 2.

Great news for Consul Catalog fans, Traefik 2. But stay on hold because I know for sure that others will follow suit. The stickiness option is the ability for a load balancer to keep using the same target for a client once it has been sent to one.

This option is now available for our CRD users! Introduced in 2. With 2. For our second example, let's see how we could use service load balancing to do canary deployments:. When you define a target with the name attribute for your IngressRouteby default, it targets a regular Service. If you want to target the new TraefikService objects, you just specify the kind attribute.

What's great with this system is that you can chain and combine them at will, creating intricate patterns depending on your needs. Below is an example that leverages both services and TraefikServicesand that uses mirroring and service load balancing at the same time!

While updating an installation to v2. You will find out how in the following guide. Pursuing the ability to configure internal services further while always giving users more control, the 2. With so many new options to customize Traefik to your every need, we understand that some people can be a bit lost when migrating to 2. So, if you're thinking about migrating but haven't jumped on the task yet, we want to point you in the right direction:.

Our community matters, and we don't want our users to feel rushed to migrate to version 2. We prefer seeing people slowly falling in love with the new tools Traefik has to offer and migrate. For this reason, we've decided to extend the support of the 1. X version until the end of That's right: you have two years ahead of you before you need to make the leap! And we believe you'll find benefits in migrating to 2. X way before that. In the introduction, we've stated that we received and are still receiving a lot of feedback about 2.

And let me tell you:. Now that we've seen people massively use Traefik 2, we decided it's time to work on making powerful features simpler to configure, or at least So, let's work together on making it happen! Come and raise your voice in the issue trackeron the community forumor better— pull request your way into making Traefik a better tool for everyone.

Traefik 2. Simplicity has always been a key feature of Traefik since the beginning and is utterly important for us, but also for you, our users.

A few months have passed since the release of Maesh General Availability.Every since the release of Traefik 2 half a year ago I wanted to give it a try. But now I found the time and while there are a couple of not-so-nice aspects, it actually works! Basically everything works as expected.

BC behind Traefik 2 (yes, that enables C/SIDE and RTC)

The fallback is NavUserPassword and I still hope I am missing something or Traefik will make something happen in response to the issue I have opened in their GitHub repo.

If you really want to take a look, this is how the configuration looks like. But to go through the configuration elements: For my first trials, I decided to go with one big docker-compose.

The configuration of Traefik itself looks like this:. If you are familiar with Traefik 1, you will see that the syntax has changed quite a bit, but basically the same things happen. The last couple of lines expose the Traefik dashboard through Traefik itself, so you can get to it through SSL. It has a new design as well and looks like this:. Beats me why they decide to ignore the check but not the create, but maybe something will be done in the future.

The labels section line 14 and on is where it gets interesting: We create a rule line 16 to let Traefik know on which DNS name and for which path the given router should listen. That one in turn connects to port 80 using HTTP because of the issue mentioned above, line 20 and The other HTTP based parts are very similar with the addition that they need to replace parts of the URL with something else when talking to the backend service.

This is done with a replacepathregex middleware, e. The TCP based parts are a lot simpler as they basically only forward a specific port to a port on a backend service, e. In the end, we have a setup that works, but having to bind SQL, Client service and Management service for every container behind Traefik to a dedicated port kind of breaks the benefit of a reverse proxy in my opinion.

Also, this is my first try with Traefik 2, so if someone comes across this post and sees aspects to simplify or otherwise improve, please let me know using the contact options in the footer.

Use Traefik with Lets Encrypt and Docker ?

I'm using traefik 2. I managed to create a default rule matching my needs, but I'm now struggling because I don't see a way to provide a default middleware to strip away prefixes. Is there a way to add a docker service label without having to provide a specific router name, but still adding a middleware to whatever router was implicitly created by traefik?

Or is there a way to define a default middleware as there is for the default rule? The solution I'm trying to approach is to remove all the variable substitutions in the following labels, thus reducing the verbosity of the whole definition but without exposing myself to naming conflicts:. Hoping it could become something like the following, where default is the magic word for using the implicit service name assigned by Docker when deploying the stack:. Learn more. Traefik 2.

Roberto Lo Giacco. I would appreciate if you explain the reason for downvoting the question when you feel the urge to do so. I have had a similar problem.

Using --providers. The problem with using the default rule is I cannot specify a default middlewares: in the above I need to strip out the prefix and I need to do it for each service I don't know how to do default middleware yet. I am looking at their forum now community. Active Oldest Votes.

Traefik 2. Traefik comes with several pre-defined middleware configurations, such as path manipulation, authentication mechanisms, circuit breaker, retry, error handling, and IP white listing. To create a gradual deployment of a new service, the new service is first defined with a unique identifier.

Then a service load balancer is created, which defines the proportion of traffic for each version of the service with the weight option. Traefik can then be configured to route traffic to this service load balancer, and the weights can be adjusted without having to redeploy the services themselves. The new dashboard provides an overview of cluster traffic and the Traefik features that can be enabled. Traefik Dashboard from the Containous blog.
