title: Running Gatling from container
body: <p>I am using denvazh/gatling container and everything works well except one thing i try to pass list of simulations like this:</p>
  
  <pre><code>Attaching to gatling
  gatling_1 | GATLING_HOME is set to /opt/gatling
  gatling_1 | Choose a simulation number:
  gatling_1 |      [0] AppsPods
  gatling_1 |      [1] ServerSimulation
  gatling_1 |      [2] computerdatabase.BasicSimulation
  gatling_1 |      [3] computerdatabase.advanced.AdvancedSimulationStep01
  gatling_1 |      [4] computerdatabase.advanced.AdvancedSimulationStep02
  gatling_1 |      [5] computerdatabase.advanced.AdvancedSimulationStep03 
  </code></pre>
  
  <p>I write such command as:</p>
  
  <pre><code>docker run -it --rm -v /home/core/gatling/conf:/opt/gatling/conf \
  -v /home/core/gatling/user-files:/opt/gatling/user-files \
  -v /home/core/gatling/results:/opt/gatling/results \
  denvazh/gatling -s AdvancedSimulationStep01
  </code></pre>
  
  <p>but nothing make sense simulation list shows again and i need to choose test from list to start the simulation. So is it possible to run only that test witch  i specify starting docker run command???</p>
