Permission denied on mkdir .../cypress/dist when installing globally about cypress-docker-images HOT 8 CLOSED

In case this helps someone else...

I'm using the jenkins declarative pipeline syntax in a Jenkinsfile, jenkins runs containers by default as the jenkins user on the host but I've found (unexpectedly) that you can override that (feel free not to use root ;) ) with:

    stage('Cypress') {
      agent {
        dockerfile {
          dir 'test/cypress'
          args '-u 0:0'
        }
      }
      steps {
        sh 'PROJECT=$(pwd) && cd /opt/cypress && $(npm bin)/cypress run --project ${PROJECT}/test/cypress'
      }
    }

With test/cypress/Dockerfile:

FROM cypress/base:8

WORKDIR /opt/cypress

RUN echo '{}' > package.json && \
    npm install cypress

Thanks @Flambe and @bahmutov for documenting!

We have recently made cypress/base:8 the default image in #34 (which upgrades Node to 8), so you should switch to building from cypress/base:6 image. Then it works

FROM cypress/base:6

RUN npm install -g cypress
RUN cypress version
RUN cypress verify

$ docker build .

It looks like this is your first time using Cypress: 2.1.0

That's worked, thank you!

Do you happen to know why node 8 breaks it?

from cypress-docker-images.

the combination of the default user and npm install permissions I think, but the use case for installing Cypress globally is pretty slim right now, so we recommend installing it locally just like a regular dependency. Plus once we do a better job caching the downloaded binary (cypress-io/cypress#1300) then it would not be very painful even locally.

from cypress-docker-images.

Ah right.

The biggest problem with caching locally (for us) is that our current CI setup runs in disposable dockers each time. This'd mean that we're still installing from scratch each time.

If you do end up pre-caching in the base images, that'd be good (for us).

from cypress-docker-images.

yeah, it is a problem. So on CircleCI and on Travis you can cache installed dependencies, even for Docker builds, other CIs should allow the same. For example cypress-example-recipes shows how to do this

• https://github.com/cypress-io/cypress-example-recipes/blob/master/circle.yml
• https://github.com/cypress-io/cypress-example-recipes/blob/master/.travis.yml

And if you are hardcore Docker user, you could make a Docker images using your dependencies as a first step of the build using something like this https://github.com/bahmutov/double-docker

from cypress-docker-images.

We're using jenkins, but yeah, there should be something out there that I can find.

Thank you for all the info and help! I'll keep looking into it.

Got exactly the same problem (cypress + docker + jenkins)
