Problem running containerized Lighthouse node 8 app in OpenShift

Not exactly related to Lighthouse, but I’m hoping someone can point me in the right direction.

A simple node 8 application using the lighthouse and chrome-launcher npm modules to generate reports against a given URL.

Everything works locally, as well as docker-ized. However, when the same docker image is deployed in OpenShift, it doesn’t work.

Since everything runs with lowest permissions level in OpenShift, could this be some permissions issue? Or maybe some environment variable/parameter for Chrome is not set correctly, causing it to not start in headless mode etc?

[patrickhulce]

Glad you got it sorted out and thanks for sharing the solution for future puzzled folks 😃

[kodeninja]

@patrickhulce nvm, I got it to work! I hadn’t put in the resources section in the OpenShift deployment config, so there wasn’t enough room for Chrome to come up and work 😁.

Thanks for all your help!
