## How Traefik is Storing and Serving TLS Certificates?
### Storing TLS Certificates
[TLS](../https/tls.md "Link to Traefik TLS docs") certificates are either provided directly by the [dynamic configuration](./configuration-overview.md#the-dynamic-configuration "Link to dynamic configuration overview") from [providers](../https/tls.md#user-defined "Link to the TLS configuration"),
or by [ACME resolvers](../https/acme.md#providers "Link to ACME resolvers"), which act themselves as providers internally.
For each TLS certificate, Traefik produces an identifier used as a key to store it.
This identifier is constructed as the alphabetically ordered concatenation of the SANs `DNSNames` and `IPAddresses` of the TLScertificate.
#### Examples:
| X509v3 Subject Alternative Name | TLS Certificate Identifier |
|-----------------------------------------|-----------------------------|
| `DNS:example.com, IP Address:127.0.0.1` | `127.0.0.1,example.com` |
| `DNS:example.com, DNS:*.example.com` | `*.example.com,example.com` |
The identifier is used to store TLS certificates in order to be later used to handle TLS connections.
This operation happens each time there are configuration changes.
If multiple TLS certificates are provided with the same SANs definition (same identifier), only the one processed first is kept.
Because the dynamic configuration is aggregated from all providers,
when processing it to gather TLS certificates,
there is no guarantee of the order in which they would be processed.
This means that along with configurations applied, it is possible that the TLS certificate retained for a given identifier differs.
### Serving TLS Certificates
For each incoming connection, Traefik is serving the "best" matching TLS certificate for the provided server name.
The TLS certificate selection process narrows down the list of TLS certificates matching the server name,
and then selects the last TLS certificate in this list after having ordered it by the identifier alphabetically.
#### Examples:
| Selected TLS Certificates Identifiers | Sorted TLS Certificates Identifiers | Served Certificate Identifier |
|-----------------------------------------------------|-----------------------------------------------------|-------------------------------|
| `127.0.0.1,example.com`,`*.example.com,example.com` | `*.example.com,example.com`,`127.0.0.1,example.com` | `127.0.0.1,example.com` |
| `*.example.com,example.com`,`example.com` | `*.example.com,example.com`,`example.com` | `example.com` |
### Caching TLS Certificates
While Traefik is serving the best matching TLS certificate for each incoming connection,
the selection process cost for each incoming connection is avoided thanks to a cache mechanism.
Once a TLS certificate has been selected as the "best" TLS certificate for a server name,
it is cached for an hour, avoiding the selection process for further connections.
Nonetheless, when a new configuration is applied, the cache is reset.

# Traefik Hub
## Overview
Once the Traefik Hub feature is enabled in Traefik,
Traefik and its local agent communicate together.
This agent can:
* get the Traefik metrics to display them in the Traefik Hub UI
* secure the Traefik routers
* provide ACME certificates to Traefik
* transfer requests from the SaaS Platform to Traefik (and then avoid the users to expose directly their infrastructure on the internet)
!!! warning "Traefik Hub Entrypoints"
When the Traefik Hub feature is enabled, Traefik exposes some services meant for the Traefik Hub Agent on dedicated entrypoints (on ports `9900` and `9901` by default).
Given their sensitive nature, those services should not be publicly exposed.
Also those dedicated entrypoints, regardless of how they are created (default, or user-defined), should not be used by anything other than the Hub Agent.
!!! important "Learn More About Traefik Hub"
This section is intended only as a brief overview for Traefik users who are not familiar with Traefik Hub.
To explore all that Traefik Hub has to offer, please consult the [Traefik Hub Documentation](https://doc.traefik.io/traefik-hub).
!!! Note "Prerequisites"
* Traefik Hub is compatible with Traefik Proxy 2.7 or later.
* The Traefik Hub Agent must be installed to connect to the Traefik Hub platform.
!!! information "Configuration Discovery"
According to installation options, the Traefik Hub Agent listens to the Docker or Kubernetes API to discover containers/services.
It doesn't support the routers discovered by Traefik Proxy using other providers, e.g., using the File provider.
!!! example "Minimal Static Configuration to Activate Traefik Hub for Docker"
```yaml tab="File (YAML)"
hub:
tls:
insecure: true
metrics:
prometheus:
addRoutersLabels: true
```
```toml tab="File (TOML)"
[hub]
[hub.tls]
insecure = true
[metrics]
[metrics.prometheus]
addRoutersLabels = true
```
```bash tab="CLI"
--hub.tls.insecure
--metrics.prometheus.addrouterslabels
```
!!! example "Minimal Static Configuration to Activate Traefik Hub for Kubernetes"
```yaml tab="File (YAML)"
hub: {}
metrics:
prometheus:
addRoutersLabels: true
```
```toml tab="File (TOML)"
[hub]
[metrics]
[metrics.prometheus]
addRoutersLabels = true
```
```bash tab="CLI"
--hub
--metrics.prometheus.addrouterslabels
```
## Configuration
### Entrypoints
#### `traefikhub-api`
This entrypoint is used to communicate between the Hub agent and Traefik.
It allows the Hub agent to create routing.
This dedicated Traefik Hub entryPoint should not be used by anything other than Traefik Hub.
The default port is `9900`.
To change the port, you have to define an entrypoint named `traefikhub-api`.
```yaml tab="File (YAML)"
entryPoints:
traefikhub-api: ":8000"
```
```toml tab="File (TOML)"
[entryPoints.traefikhub-api]
address = ":8000"
```
```bash tab="CLI"
--entrypoints.traefikhub-api.address=:8000
```
#### `traefikhub-tunl`
This entrypoint is used to communicate between Traefik Hub and Traefik.
It allows to create secured tunnels.
This dedicated Traefik Hub entryPoint should not be used by anything other than Traefik Hub.
The default port is `9901`.
To change the port, you have to define an entrypoint named `traefikhub-tunl`.
```yaml tab="File (YAML)"
entryPoints:
traefikhub-tunl: ":8000"
```
```toml tab="File (TOML)"
[entryPoints.traefikhub-tunl]
address = ":8000"
```
```bash tab="CLI"
--entrypoints.traefikhub-tunl.address=:8000
```
### `tls`
_Optional, Default=None_
This section is required when using the Hub agent for Docker.
This section allows configuring mutual TLS connection between Traefik Proxy and the Traefik Hub Agent.
The key and the certificate are the credentials for Traefik Proxy as a TLS client.
The certificate authority authenticates the Traefik Hub Agent certificate.
!!! note "Certificate Domain"
The certificate must be valid for the `proxy.traefik` domain.
!!! note "Certificates Definition"
Certificates can be defined either by their content or their path.
!!! note "Insecure Mode"
The `insecure` option is mutually exclusive with any other option.
```yaml tab="File (YAML)"
hub:
tls:
ca: /path/to/ca.pem
cert: /path/to/cert.pem
key: /path/to/key.pem
```
```toml tab="File (TOML)"
[hub.tls]
ca= "/path/to/ca.pem"
cert= "/path/to/cert.pem"
key= "/path/to/key.pem"
```
```bash tab="CLI"
--hub.tls.ca=/path/to/ca.pem
--hub.tls.cert=/path/to/cert.pem
--hub.tls.key=/path/to/key.pem
```
### `tls.ca`
The certificate authority authenticates the Traefik Hub Agent certificate.
```yaml tab="File (YAML)"

!!! warning "Security Consideration"
Do not use this setup in production.
This option implies sensitive data can be exposed to potential malicious third-party programs.
