How i can install my docker EE in AWS ec2 redhat 8… once i install docker SELinux i got error message on FAILED DEPENDENCIES.
Are you facing problems with installing Docker EE?
When it commes to Docker EE, the latest supported RHEL version is 7.6 according the compatiblity matrix:
https://success.docker.com/article/compatibility-matrix
When it commes to Docker CE, Docker Inc. never released a Docker CE package for any version of RHEL.
So the only possible target left is: you are raising an issue for something that is not supported 
Maybee someone is willing to tell you how to make a “frankendocker” installation on RHEL8, though I would strongly suggest to NOT use it for productive purposes.
