      Installing Docker as Described Here:

      https://docs.docker.com/install/linux/docker-ce/fedora/

      Everything seems to work.

      Then setup Guacamole as described here:

      https://linode.com/docs/applications/remote-desktop/remote-desktop-using-apache-guacamole-on-docker/#initialize-guacamole-authentication-with-mysql

      Everything seems to work pefectly, but http://HOSTNAME:8080/guacamole/ doesn't load.

      I disabled the firewall, made no difference.

              Did you try setting SELinux to permissive?

                @black3dynamite Not yet. Hopefully I’ll be able to try it again soon.

                    Check NoVNC it is much easier and simpler project and provides same functionality but poorer visual but I think better reliability cause it is simpler.

                      I've tried Guacamole on CentOS and Debian. Both worked fine, but it was a bare-metal install (not docker). Check Guacamole and Tomcat logs to identify if they are running at all and try to see your connection attempts there. If there is nothing it has to be firewall/connectivity issue.

                        I have did the same as above. My issue is with the VNC / SSH connection. Any pointer for resolving?

                        From the link given, i am not able to create the tunnel as well
                        ssh -L 5901:localhost:5901 -N -f -l user example.com

                        my guacamole log:

                          And the verdict was?

                            Any reason you went with the Docker third party repos instead of letting Fedora manage it?

                              @scottalanmiller Fedora was too old of date at the time.

                                The Docker instructions don't seem to work, which seems to be my experience with all Docker instructions. Sounds like it'll be easy, but never "just works" and takes more complicated fiddling than just doing traditional installs.
