nodejs pull offer and push to system

1. local way : git clone , update files , vm path , vm ls , vm start swarm1, vm conn swarm1
   question: how to ensure local files could be accessed within the container since swarm1 itself is a virtual machine and container runs insied it.
   method:change the vm setting in vbox
   advantage : no néed to git push before code ok
2. use mex local machine
   git push,git pull,docker build,docker run
   disadvantage: git push all the time if code needs changes
3. mex aliyun docker on quizbid
   gitlab binding automatically deployment
   no need to copy code and more
   a delay to see the result
4. mex local docker automatically gitlab binding
