ManicTime Server receives data from ManicTime clients installed on your network and provides reports, which you can view with a web browser.
After creating the container, stop the container and run this command in a shell (SSH Login or GUI Console) on your Unraid server, to create the admin user.
Change the directory if you have used a different path (/mnt/user/appdata/manictimeserver) and be sure to change the username and password!.
docker run -v /mnt/user/appdata/manictimeserver:/app/Data -p 8080:8080 --rm --entrypoint dotnet manictime/manictimeserver ManicTimeServer.dll addadmin -u admin@Unraidserver.com -p someSecretPassword
After that, you can start the container as usual.
