We construct soliton solution of a variable coefficients nonlinearSchr\"odinger equation in the presence of parity reflection - time reversal$(\mathcal{PT})-$ symmetric Rosen-Morse potential using similaritytransformation technique. We transform the variable coefficients nonlinearSchr\"odinger equation into the nonlinear Schr\"odinger equation with$\mathcal{PT}-$symmetric potential with certain integrability conditions. Weinvestigate in-detail the features of the obtained soliton solutions with twodifferent forms of dispersion parameters. Further, we analyze the nonlineartunneling effect of soliton profiles by considering two different forms ofnonlinear barrier/well and dispersion barrier/well. Our results show that thesoliton can tunnel through nonlinear barrier/well and dispersion barrier/wellwith enlarged and suppressed amplitudes depending on the sign of the height.Our theoretical findings are experimentally realizable and might help to modelthe optical devices.
