# Tailscale
Provision TLS certificates for your internal Tailscale services.
{: .subtitle }
To protect a service with TLS, a certificate from a public Certificate Authority is needed.
In addition to its vpn role, Tailscale can also [provide certificates](https://tailscale.com/kb/1153/enabling-https/) for the machines in your Tailscale network.
## Certificate resolvers
To obtain a TLS certificate from the Tailscale daemon,
a Tailscale certificate resolver needs to be configured as below.
!!! info "Referencing a certificate resolver"
Defining a certificate resolver does not imply that routers are going to use it automatically.
Each router or entrypoint that is meant to use the resolver must explicitly [reference](../routing/routers/index.md#certresolver) it.
```yaml tab="File (YAML)"
certificatesResolvers:
myresolver:
tailscale: {}
```
```toml tab="File (TOML)"
[certificatesResolvers.myresolver.tailscale]
```
```bash tab="CLI"
--certificatesresolvers.myresolver.tailscale=true
```
## Domain Definition
A certificate resolver requests certificates for a set of domain names inferred from routers, according to the following:
- If the router has a [`tls.domains`](../routing/routers/index.md#domains) option set,
then the certificate resolver derives this router domain name from the `main` option of `tls.domains`.
- Otherwise, the certificate resolver derives the domain name from any `Host()` or `HostSNI()` matchers
in the [router's rule](../routing/routers/index.md#rule).
!!! info "Tailscale Domain Format"
The domain is only taken into account if it is a Tailscale-specific one,
i.e. of the form `machine-name.domains-alias.ts.net`.
## Configuration Example
!!! example "Enabling Tailscale certificate resolution"
```yaml tab="File (YAML)"
entryPoints:
web:
address: ":80"
websecure:
address: ":443"
certificatesResolvers:
myresolver:
tailscale: {}
```
```toml tab="File (TOML)"
[entryPoints]
[entryPoints.web]
address = ":80"
[entryPoints.websecure]
address = ":443"
[certificatesResolvers.myresolver.tailscale]
```
```bash tab="CLI"
--entrypoints.web.address=:80
--entrypoints.websecure.address=:443
# ...
--certificatesresolvers.myresolver.tailscale=true
```

```
## Automatic Renewals
Traefik automatically tracks the expiry date of each Tailscale certificate it fetches,
and starts to renew a certificate 14 days before its expiry to match Tailscale daemon renew policy.
