dockerHostHostname function

String? dockerHostHostname()

Returns the hostname portion of an SSH-based Docker host URL.

For example, ssh://[e-mail] returns 'myhost.example.com'.

Returns null when dockerHost is not an SSH URL or the host component is empty.

Implementation

String? dockerHostHostname() {
  final rawHost = dockerHost();
  if (rawHost == null || !rawHost.startsWith('ssh://')) {
    return null;
  }
  final uri = Uri.parse(rawHost);
  return uri.host.isNotEmpty ? uri.host : null;
}
