#### Wildcard Domains
@ -299,140 +308,56 @@ acme:
[ACME V2](https://community.letsencrypt.org/t/acme-v2-and-wildcard-certificate-support-is-live/55579) supports wildcard certificates.
As described in [Let's Encrypt's post](https://community.letsencrypt.org/t/staging-endpoint-for-acme-v2/49605) wildcard certificates can only be generated through a [`DNS-01` challenge](#dnschallenge).
```toml tab="TOML"
[acme]
# ...
[[acme.domains]]
main = "*.local1.com"
sans = ["local1.com"]
# ...
```
```yaml tab="YAML"
acme:
# ...
domains:
- main: "*.local1.com"
sans:
- local1.com
# ...
```
!!! note "Double Wildcard Certificates"
It is not possible to request a double wildcard certificate for a domain (for example `*.*.local.com`).
Most likely the root domain should receive a certificate too, so it needs to be specified as SAN and 2 `DNS-01` challenges are executed.
In this case the generated DNS TXT record for both domains is the same.
Even though this behavior is [DNS RFC](https://community.letsencrypt.org/t/wildcard-issuance-two-txt-records-for-the-same-name/54528/2) compliant,
it can lead to problems as all DNS providers keep DNS records cached for a given time (TTL) and this TTL can be greater than the challenge timeout making the `DNS-01` challenge fail.
The Traefik ACME client library [LEGO](https://github.com/go-acme/lego) supports some but not all DNS providers to work around this issue.
The [Supported `provider` table](#providers) indicates if they allow generating certificates for a wildcard domain and its root domain.
## Known Domains, SANs
You can set SANs (alternative domains) for each main domain.
Every domain must have A/AAAA records pointing to Traefik.
Each domain & SAN will lead to a certificate request.
```toml tab="TOML"
[acme]
# ...
[[acme.domains]]
main = "local1.com"
sans = ["test1.local1.com", "test2.local1.com"]
[[acme.domains]]
main = "local2.com"
[[acme.domains]]
main = "*.local3.com"
sans = ["local3.com", "test1.test1.local3.com"]
# ...
```
```yaml tab="YAML"
acme:
# ...
domains:
- main: "local1.com"
sans:
- "test1.local1.com"
- "test2.local1.com"
- main: "local2.com"
- main: "*.local3.com"
sans:
- "local3.com"
- "test1.test1.local3.com"
# ...
```
!!! important
The certificates for the domains listed in `acme.domains` are negotiated at Traefik startup only.
!!! note
Wildcard certificates can only be verified through a `DNS-01` challenge.
## `caServer`
??? example "Using the Let's Encrypt staging server"
```toml tab="TOML"
[acme]
```toml tab="File (TOML)"
[certificatesResolvers.sample.acme]
# ...
caServer = "https://acme-staging-v02.api.letsencrypt.org/directory"
# ...
```
```yaml tab="YAML"
acme:
# ...
caServer: https://acme-staging-v02.api.letsencrypt.org/directory
# ...
```yaml tab="File (YAML)"
certificatesResolvers:
sample:
acme:
# ...
caServer: https://acme-staging-v02.api.letsencrypt.org/directory
# ...
```
## `onHostRule`
Enable certificate generation on [routers](../routing/routers/index.md) `Host` & `HostSNI` rules.
This will request a certificate from Let's Encrypt for each router with a Host rule.
```toml tab="TOML"
[acme]
# ...
onHostRule = true
# ...
```
```yaml tab="YAML"
acme:
# ...
onHostRule: true
# ...
```
!!! note "Multiple Hosts in a Rule"
The rule `Host(test1.traefik.io,test2.traefik.io)` will request a certificate with the main domain `test1.traefik.io` and SAN `test2.traefik.io`.
!!! warning
`onHostRule` option can not be used to generate wildcard certificates. Refer to [wildcard generation](#wildcard-domains) for further information.
```bash tab="CLI"
# ...
--certificatesResolvers.sample.acme.caServer="https://acme-staging-v02.api.letsencrypt.org/directory"
# ...
```
## `storage`
The `storage` option sets the location where your ACME certificates are saved to.
```toml tab="TOML"
[acme]
```toml tab="File (TOML)"
[certificatesResolvers.sample.acme]
# ...
storage = "acme.json"
# ...
```
```yaml tab="YAML"
acme
# ...
storage: acme.json
# ...
```toml tab="File (TOML)"
certificatesResolvers:
sample:
acme:
# ...
storage: acme.json
# ...
```
```bash tab="CLI"
# ...
--certificatesResolvers.sample.acme.storage=acme.json
# ...
```
The value can refer to some kinds of storage:

[ACME v2](https://community.letsencrypt.org/t/acme-v2-and-wildcard-certificate-support-is-live/55579) supports wildcard certificates.
As described in [Let's Encrypt's post](https://community.letsencrypt.org/t/staging-endpoint-for-acme-v2/49605) wildcard certificates can only be generated through a [`DNS-01` challenge](./../../https/acme.md#dnschallenge).
Most likely the root domain should receive a certificate too, so it needs to be specified as SAN and 2 `DNS-01` challenges are executed.
In this case the generated DNS TXT record for both domains is the same.
Even though this behavior is [DNS RFC](https://community.letsencrypt.org/t/wildcard-issuance-two-txt-records-for-the-same-name/54528/2) compliant,
it can lead to problems as all DNS providers keep DNS records cached for a given time (TTL) and this TTL can be greater than the challenge timeout making the `DNS-01` challenge fail.
The Traefik ACME client library [LEGO](https://github.com/go-acme/lego) supports some but not all DNS providers to work around this issue.
The [Supported `provider` table](./../../https/acme.md#providers) indicates if they allow generating certificates for a wildcard domain and its root domain.
!!! note
Wildcard certificates can only be verified through a `DNS-01` challenge.
!!! note "Double Wildcard Certificates"
It is not possible to request a double wildcard certificate for a domain (for example `*.*.local.com`).
