If your project is situated on Mia-Platform PaaS, you can immediately take advantage of a Traefik installation to fulfill all your networking needs.

But what can you do exactly with Traefik?

  • Expose endpoints with ease and route traffic to your services (through the api-gateway);
  • Configure various middlewares, such as basic authentication for specific pages, forwards or whitelists;
  • Set up TLS connections with a simple configuration.

To configure TLS capabilities in the PaaS, you can check our Cert-Manager Documentation.

In order to configure the routing to your services, you need to create a DNS records pointing to the public IP address exposed by Traefik. Once the DNS is set up correctly, you can start writing Traefik configuration files to set up the rest.

Expose an endpoint

The YAML configuration file responsible to route traffic to your services is the IngressRoute. The service where we route the traffic will always be the api-gateway. You can check a IngressRoute example configuration below:

kind: IngressRoute
name: default-ingress
labels: "ingress-controller"
- websecure
- match: Host(`<host>`)
- name: ingress-controller-hsts-headers
namespace: mia-platform
- name: "<middleware-name>"
namespace: <middleware-namespace>
kind: Rule
- name: api-gateway
port: 8080
secretName: <tls-secret>

You will need to valorize the fields contained in the angle brackets (<>):

  • host: the hostname that you want to expose (e.g.
  • middleware-name: The name of the Traefik Middleware resource that you want to apply
  • middleware-namespace: The nama of the namespace where the middleware has been created
  • tls-secret: the name of the secret containing the tls certificate

Note: you need to include the middleware ingress-controller-hsts-headers to allow clients to upgrade the connection to https.

Note 2: The label "ingress-controller" is necessary in this resources to let Traefik discover them.

This configuration need to be put in the intended Environment configuration folder of your project, it differs between Base projects and Kustomize projects.

  • Base project: The resource needs to be saved in the path configuration/<environmentId>/<resource.yaml>.
  • Kustomize project: The resource needs to be saved in the path overlays/<environmentId>/<resource.yaml>.


Traefik implements a number of Middlewares[1] that are available for everyone on the PaaS to use. The Traefik resource to use in this case is the Middleware resource and it may be created in the environment where the Ingressroute is placed, but it is possible to refer to Middlewares from other environments.

Below a simple example of Basic Authentication, a Middleware useful to set a username-password authentication to selected endpoints. First of all, you need to create a resource Middleware in your configuration folder (if you want to create it in every Environment) or in the path configuration/<environmentId>/<resource.yaml> if you want to create it in an Environment of a Base project, or in the path overlays/<environmentId>/<resource.yaml> if you want to create it in a specific environment in a Kustomize project.

kind: Middleware
name: test-auth
labels: "ingress-controller"
secret: authsecret

Above an example of Middleware. (to make it work, this specific middleware also needs a secret with the credentials [1])

Note: Also in middlewares the label "ingress-controller" is needed.

TLS Configuration

To enable TLS for an your hostname is necessary to create a TLS Certificate and store it as secret in the environment where the Ingressroute is present.

To create the certificate in the PaaS, you can use the Cert-Manager instance already present in the cluster, you can find more on that in the dedicated section.

After creating the certificate, you can select it in the section tls/SecretName in the IngressRoute resource.

secretName: <tls-secret>


When deploying resources of type IngressRoute in Mia-platform's PaaS, you have to your disposal various TLSOptions files that can be used as pre-made set of configurations.

The TLSOptions ready to be used are:

  • ingress-controller-old-tls: supports older clients and TLS 1.0
  • ingress-controller-modern-tls: drops support for older clients and supports only TLS 1.3
  • ingress-controller-intermediate-tls: the balanced option, optimal to achieve A+ on SSLLabs test

Note: If you do not specify a TLSOption, the intermediate is applied by default.

You can use these TLSOptions in your IngressRoute by specifying them in your configuration:

name: ingress-controller-old-tls
namespace: mia-platform

Note: These resources are deployed in the namespace mia-platform

In addition, you can deploy your personal TLSOption and then refer it in the same way in your Traefik resources.

Leaving the TLS block empty

It is also possible to leave the TLS block empty when building your IngressRoute. Doing so, your IngressRoute will use a default certificate issued for the cluster, created to match:

  • '*'
  • '*'

In the production cluster, and:

  • '*'
  • '*'
  • '*'
  • '*'
  • '*'
  • '*'

In the development cluster.
