Error while suiteCRM setup

Hello all,

I am trying to setup suiteCRM with docker engine.

I am using UBUNTU 14.04 with 3.19.0-49-generic.

The below error is driving me crazy in “Database Configuration” step while setting up suiteCRM which has been running through docker.

“The provided database host, username, and/or password is invalid, and a connection to the database could not be established. Please enter a valid host, username and password”

I am following steps mentioned at:
https://github.com/Spantree/docker-suitecrm

I am using command :
docker run --name mysuitecrm -e DB_HOST_NAME=localhost -e DATABASE_NAME=suiteCRMDB -e DB_USER_NAME=bhargav -e DB_PASSWORD=bhargav -e DB_TYPE=mysql -e DB_TCP_PORT=3306 -e DB_MANAGER=MysqlManager -p 2080:80 -d spantree/suitecrm

MySQL is running at localhost and user named bhargav has been granted all the privilages including create DB.

It is my humble request if anybody can help to resolve this issue.

Any help will be appreciated.
