+to use gitlab ci-cd
+create ci yaml file on the root of project
+
+have to setup runner to make ci works
+
+need gitlab-runner install and run 
+gitlab-runner
+here is how I did:
+#install
+curl -L "https://packages.gitlab.com/install/repositories/runner/gitlab-runner/script.deb.sh" | sudo bash
+#register
+sudo gitlab-register
+#type in gitlab https for example: https://gitlab.micsapp.com
+#type in token 
+#above info canbe found on gitlab runner manger page
+#choose runner mode: [ssh, docker, etc...]
+#if chhose docker will ask what base image you want to use
+#for example in this project we can use simple ubuntu docker image
+#tag for runner to pick up project 
+(note: this is important, in ci yaml file need to provide tag matched with this, otherwise won't pick up the job)
+
+#after register
+#run it
+sudo -s gitlab-runner start
+#check status
+sudo gitlab-runner status
+
