Current log is

             [10:22:21][Step 5/5] docker: Terminating images (if needed)
             [10:22:21][docker] Executing command: docker kill teamcity_tJkCfFeZ97f6tJHLLKePbM4VAYXYaWS8 2>&1 || true

             [10:22:21][docker] Process exited with code 0

This makes build script contain 'error' that frighten end-users

Could use

if docker ps | grep 'teamcity-HASH' ; then 
  docker kill 'teamcity-HASH' 
fi
exit 0
