Certificates
SNI bindings
Attach certificates to hosts for hostname-based TLS selection.
Goal
Bind a certificate as the primary SNI cert for a host.
Steps
- Open the certificate detail → Bindings.
- Select the proxy host / hostname.
- Mark primary SNI as required by the UI.
- Save (auto-publish typical).
- Enable HTTPS on the Proxy (
DataPlane:Https:Enabled=true, listen port).
Runtime
Proxy CertificateRuntimeStore maps hostname → certificate (exact and imported wildcard material when present). Kestrel uses ServerCertificateSelector for SNI.
Verify
openssl s_client -connect <proxy-host>:<https-port> -servername <hostname>
Confirm the expected certificate subject/SAN.
