So, could you let us know what are you trying to achieve? Are you trying to access to the URL where the Parse application are running and you don't know the password? In this case, you can follow the steps described in this guide in order to obtain the credentials of your application:
Please note that this password is only shown the first time you start the image. If you have restarted the server in some way, you won't be able to recover it again.
On the other hand, are you trying to write your own custom functions on the top of the Parse Server and you need to access the server? In this case you would need to use SSH to connect to the server, that is, you need to run a command like:
ssh -i KEY bitnami@IP-OF-YOUR-SERVER
Note that the previous command needs to know if you are the real owner of your server, so its need a key (which is the
-i KEY part). That key is selected when you first launch the instance.
You can follow the steps described in this guide to find all the details about how you can connect to your server using SSH:
If you have any issue, please let us know exactly in what step of the guides are you stuck. In that way we could help you in a better way.
Hope it helps,
