The TLS options allow one to configure some parameters of the TLS connection.
!!! important "'default' TLS Option"
The `default` option is special.
When no tls options are specified in a tls router, the `default` option is used.
When specifying the `default` option explicitly, make sure not to specify provider namespace as the `default` option does not have one.
Conversely, for cross-provider references, for example, when referencing the file provider from a docker label,
you must specify the provider namespace, for example:
`traefik.http.routers.myrouter.tls.options=myoptions@file`
!!! important "TLSOptions in Kubernetes"
When using the TLSOptions-CRD in Kubernetes, one might setup a default set of options that,
if not explicitly overwritten, should apply to all ingresses. To achieve that, you'll have to
create a TLSOptions CR with the name `default`. There may exist only one TLSOption with the
name `default` (across all namespaces) - otherwise they will be dropped.
To explicitly use a different TLSOption (and using the Kubernetes Ingress resources) you'll
have to add an annotation to the Ingress in the following form:
