Issue with accessing webpage (uploaded on wildfly)
The issue is with running the container. Try adding access to the app from all interfaces:
docker run -p 8080:8080 -p 9990:9990 --name wildfly -d -it jboss/wildfly `/opt/jboss/wildfly/bin/standalone.sh -b 0.0.0.0 -bmanagement 0.0.0.0`
The only thing that you were missing was: -b 0.0.0.0
