Complete CI pipeline demo

Now we can set up a jenkins server and connect to kubernetes. Yet a more detailed example illustrating how a pipeline is created and used is called for.

Can not find docker in Jenkins' build pipeline.

Not an issue of plugin cuz when I type

kubectl exec -it jenkins-2713620618-c27w2 -- /bin/bash 

and we can see there is /var/run/docker.sock, yet the docker command is not found.

jenkins@ip-10-0-226-111:/$ docker
bash: docker: command not found
jenkins@ip-10-0-226-111:/$ ls                      
bin  boot  dev	docker-java-home  etc  home  lib  lib64  media	mnt  opt  proc	root  run  sbin  srv  sys  tmp	usr  var
jenkins@ip-10-0-226-111:/$ cd var/run
jenkins@ip-10-0-226-111:/var/run$ ls
docker.sock  lock  mount  secrets  utmp

Okay I got way too stuck here so I posted a question on stackoverflow. Here's the link:

Meanwhile I'll go ahead and create our custom slave image (with docker client and kubectl installed).
