npm install fails in jenkins pipeline in docker

Question

I\'m following a tutorial about Jenkins pipeline and I can get a \"hello world\" working under at node 6.10 docker container.

But, when I added a default EmberJS app

Answer 1

In my case the problem was that inside the container I was user jenkins instead of root. I got there by setting whoami inside the container and got error like cannot determine user 111 (which happens to be jenkins). So I did the following:

stage('Run build') {
        webappImage.inside("-u root") {
            sh "yarn run build"
        }
    }
