Jenkins shell不解释$variables

我正在尝试使用jenkins在prod机器上的docker容器内部署nodejs应用程序

我有这个贝壳：

ssh -tt vagrant@10.2.3.129<<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

詹金斯似乎不执行“

$（docker ps-q）

” 和“

$（docker ps-a-q）

”

因此，

docker kill

和

docker rm

得到了0个参数

但是为什么会发生这种情况呢？

我发现了这个问题

我只需要将“

$

”替换为“

\$

”。 这就解决了问题
