To be completed by the original poster:
I have followed the full set up support page for docker and when I get to it all downloaded etc in the powershell and try to access it at local host on my web browser this is the message I get.
Fatal Error - sorry this shouldn’t happen. SQLSTATE[HY000]  Access denied for user ‘cms’@‘172.18.0.5’ (using password: NO)
Any help with this would be greatly appreciated!
Provide screenshots where possible!
