Passing Jenkins Pipeline parameter to a Dockerfile - docker

Question

I'm getting a "Bad substitution" error when trying to pass a pipeline parameter to the Dockerfile.
Jenkins parameter: version
Jenkinsfile:
pipeline {
agent any
stages {
stage('Build in docker container') {
agent { dockerfile true }
steps {
sh 'node -v'
}
}
}
}
Dockerfile:
FROM ubuntu:16.04
WORKDIR /root
# install dependencies
RUN apt-get update
RUN apt-get install curl wget vim nano zip git htop ncdu build-essential chrpath libssl-dev libxft-dev apt-transport-https -y
# install node 10
RUN curl -sL https://deb.nodesource.com/setup_10.x | bash
RUN apt-get install --yes nodejs
#RUN node -v
#RUN npm -v
RUN echo ${params.version}
#ARG VERSION
#RUN echo $VERSION

I'm sure the problem is that im new to pipelines/docker. :)
I would be grateful for any help.

Answer 1

issue resolved by adding the ARG variable to the Dockerfile.
This is how the Dockerfile looks like:
FROM ubuntu:16.04
WORKDIR /root
# install dependencies
RUN apt-get update
RUN apt-get install curl wget vim nano zip git htop ncdu build-essential chrpath libssl-dev libxft-dev apt-transport-https -y
# install node 10
RUN curl -sL https://deb.nodesource.com/setup_10.x | bash
RUN apt-get install --yes nodejs
#RUN node -v
#RUN npm -v
ARG version=fisticuff
RUN echo $version
and this is how the Jenkinsfile looks like:
pipeline {
agent any
stages {
stage('Build in docker container') {
agent {
dockerfile {
additionalBuildArgs '--build-arg version="$version"'
}
}
steps {
sh 'node -v'
}
}
}
}

Much obliged to all of you for giving me the hints. It helped me a lot!

Try running Dockerfile independently first.
Since you are new to docker try one step at a time.
