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

When Jenkins runs the stage in Docker agent it usually sets HOME=/ (image WORKDIR value), but Jenkins user does not have write permissions in this directory, that's why npm cannot create its cache directory ~/.npm. To solve this you need either to override HOME or NPM default cache directory:

environment {
    // Override HOME to WORKSPACE
    HOME = "${WORKSPACE}"
    // or override default cache directory (~/.npm)
    NPM_CONFIG_CACHE = "${WORKSPACE}/.npm"
}
