@DanielRuf Better place for this https://github.com/webpack-contrib/webpack-defaults and when we update to latest default 👍 Also looks broken on node10 😞

[DanielRuf]

Probably not broken but just a wrong image name

Error response from daemon: repository webpackcontrib/circleci-node10 not found: does not exist or no pull access

[DanielRuf]

Yep, no Node.js 10 image, just 6, 8 and 9.

@DanielRuf looks we need create image for node 10 (like this https://github.com/webpack-contrib/circleci-jdk9-node9)

If you want help us with webpack and webpack-contrib, it may be helpful to give you more permission on webpack-contrib. Looks on you github profile I would be glad to see such a person in our webpack and webpack-contrib orgs. But it's not in my competence.
