Latest image has not yarn installed despite README saying so

[vampolo]

Latest changes that brought node v8 and yarn do not fully install yarn as the installation is prevented by an if statement at line 30 of the dockerfile

  if [ -z "$CONFIG_FLAGS" ]; then \

Proof

Works fine for me:

$ docker run mhart/alpine-node:latest yarn --version
0.24.6

Are you sure you're not looking at the Dockerfile from a base image (which has a static build of nodejs with no npm or yarn)?

[nazimjamil]

What does your dockerfile look like @mhart? I'm not able to use Yarn when building with FROM mhart/alpine-node:base-6.

[mhart]

@nazimjamil the base images are builds of Node.js as a static binary – no npm or yarn in those builds. Use those builds for when you have no dependencies – or you just have JS dependencies that are already installed when you run docker build

@vampolo going to mark this as closed, as the latest image clearly has yarn – let me know if you can reproduce your issue

[vampolo]

@mhart yeah it is all good. Yarn is installed for root user only. as soon as i switched to another user in my dockerfile i wasn't able to use yarn anymore.
Seems not a problem strictly related to alpine-node, but it was the way i was using it.
Besides, if yarn was installed globally like npm, any user on alpine-node would not have this problem.

[mhart]

Hmmm, this is a good point – the install script for yarn uses the home directory, but I'm thinking it might be better to add it in a more global directory.

I'll play around with some things and update here

[mhart]

Ok, I've decided to install it in /usr/local/share/yarn – and symlink in /usr/local/bin

Have updated the latest, 8, 8.0, and 8.0.0 images with these changes

Brilliant! thank you!
