How do we install npm pdf-parse library in jenkins docker container - docker

Question

While running the Cypress tests on jenkins, I am getting the below error. Our jenkins is integrated with Docker container and devs asked me to install the pdf-parse library in docker container which will solve the issue. How do I install pdf-parse in docker container, which file does that ? Could some one please advise ?
Note: I am unable to see a docker file in my project root directory
11:38:29 Or you might have renamed the extension of your `pluginsFile`. If that's the case, restart the test runner.

11:38:29 Please fix this, or set `pluginsFile` to `false` if a plugins file is not necessary for your project.

I suppose you use cypress/base:10 as the image to new a container in jenkins. If you don't have dockerfile, you may have to write your own dockerfile extends from cypress/base:10.
Dockerfile:
FROM cypress/base:10
RUN npm install pdf-parse
Then, docker build -t mycypress ., docker push mycypress to push the image to dockerhub(You may need an account) to let your jenkins use your new image to setup container.
NOTE: you will have to find how your project choose image to start your container, with this, you can find suitable way to install pdf-parse. One possible maybe next:
pipeline {
agent {
docker { image 'cypress/base:10' }
}
stages {
stage('Test') {
steps {
sh 'node --version'
}
}
}
}
Then, you may change docker { image 'cypress/base:10' } to docker { image 'mycypress' }.
