Docker server x not found in known_hosts

Hello.

Is there a way to add a server to known hosts using docker api?

        connection = docker.APIClient(
            base_url=f"ssh://{user}@{host}")
        data = {
            "name": server_name,
            "connection": connection
        }
        self.connections.append(data)

paramiko.ssh_exception.SSHException: Server 'x' not found in known_hosts

Because the server I am trying to create a docker api client with is new, it is not in my known_hosts. I was wondering if its possible to add it to the known hosts inside of docker api? Because the api client automatically tries to login to the ssh connection when you make the instance of the class, meaning I am not able to access the paramiko client to add the host to known hosts.

The issue mentions Docker APIClient, an SSH base_url, and Paramiko's known_hosts handling, but names no repository files or tests. Start by locating the APIClient SSH connection setup and checking how Paramiko loads known_hosts. Done should be defined as a documented, tested way to handle a new server's host key through the Docker client.
