connect static method

Future<DockerClient> connect({ Map<String, String>? environment, })

Finds the daemon (DockerEndpoint.resolve) and checks it answers.

Throws a DockerUnavailableException with the reason when it does not.

Implementation

static Future<DockerClient> connect({
  Map<String, String>? environment,
}) async {
  final endpoint = DockerEndpoint.resolve(environment: environment);
  if (endpoint == null) {
    throw DockerUnavailableException(
      DockerEndpoint.unavailableReason(environment: environment) ??
          'No Docker daemon found',
    );
  }
  final client = DockerClient(endpoint);
  try {
    await client.ping();
  } on Object {
    client.close();
    rethrow;
  }
  return client;
}
