Then I ahose into added those two containers into a service alias.then I added then I added a loadbalancer to the alias. but I am not able to access my access my application through browser.
can anyone help me on this?

Simply create a stack, then create a service in the stack, scale it as appropriate. Then go ahead and create LB inside your stack. LB can be tied to the service or you can use selectors.
