for future brothers comes this topic about executing selenium as a service at linux vps with docker;
guys, dont forget, docker is NEW COMPUTER. if you have chromedriver on your computer , selenium uses at LOCAL.
but
if you are trying to dockerize application at vps , you HAVE TO create a DOCKERFILE and tell docker "HEY DOWNLOAD CHROME DRIVER FOR ME"

if you download chrome-driver to your vps machine and dockerize app, still no working.
i hope someone can use this comment and fix his problem.
