Here is an example to run ls remotely using your "plain private key file".

    pemBytes, err := ioutil.ReadFile("/location/to/YOUR.pem")
    if err != nil {
        log.Fatal(err)
    }
    signer, err := ssh.ParsePrivateKey(pemBytes)
    if err != nil {
        log.Fatalf("parse key failed:%v", err)
    }
    config := &ssh.ClientConfig{
        User: "ubuntu",
        Auth: []ssh.AuthMethod{ssh.PublicKeys(signer)},
    }
    conn, err := ssh.Dial("tcp", "yourhost.com:22", config)
    if err != nil {
        log.Fatalf("dial failed:%v", err)
    }
    defer conn.Close()
    session, err := conn.NewSession()
    if err != nil {
        log.Fatalf("session failed:%v", err)
    }
    defer session.Close()
    var stdoutBuf bytes.Buffer
    session.Stdout = &stdoutBuf
    err = session.Run("ls -l")
    if err != nil {
        log.Fatalf("Run failed:%v", err)
    }
    log.Printf(">%s", stdoutBuf)
