Jenkins shell dont interpret $ variables

I am trying to deploy a nodejs app inside docker container on a prod machine using jenkins.

I have this shell :

ssh -tt [email protected]<<EOF
cd ~/app/backend
git pull
cat <<EOM >./Dockerfile
FROM node:8
WORKDIR /usr/src/app
COPY package*.json ./
RUN npm install
COPY . .
EXPOSE 3000
CMD [ "npm", "start" ]
EOM
docker build -t vagrant/node-web-app .
docker kill $(docker ps -q)
docker rm $(docker ps -a -q)
docker run -p 3000:3000 -d vagrant/node-web-app
exit
EOF

this will connect via ssh to prod machine and create a Dockerfile then build and run image. but it failed. and this a part of the jenkins logs: 

Successfully built 8e5796ea9846
vagrant@ubuntu-xenial:~$ docker kill 

"docker kill" requires at least 1 argument.
See 'docker kill --help'.

Usage:  docker kill [OPTIONS] CONTAINER [CONTAINER...]

Kill one or more running containers
vagrant@ubuntu-xenial:~$ docker rm 
"docker rm" requires at least 1 argument.
See 'docker rm --help'.

Usage:  docker rm [OPTIONS] CONTAINER [CONTAINER...]

Remove one or more containers
vagrant@ubuntu-xenial:~$ docker run -p 3000:3000 -d vagrant/node-web-app

vagrant@ubuntu-xenial:~$ exit
logout
Connection to 10.2.1.129 closed.
Build step 'Execute shell' marked build as failure
Finished: FAILURE

It seems like jenkins dont execute the " $(docker ps -q) " and " $(docker ps -a -q) "

so docker kill and docker rm got 0 arguments.

But why this happen ?

I found the issue,

Just I have to replace "$" with "\$" . this solve the problem.
