How do you use this docker image

[rocel]

Hi,
I've tried something like :
docker run weboaks/node-karma-protractor-chrome npm test

but I get :

npm ERR! Linux 4.9.4-moby
npm ERR! argv "/usr/bin/nodejs" "/usr/bin/npm" "test"
npm ERR! node v7.4.0
npm ERR! npm v4.0.5
npm ERR! path /package.json

npm ERR! errno -2
npm ERR! syscall open

npm ERR! enoent ENOENT: no such file or directory, open '/package.json'
npm ERR! enoent ENOENT: no such file or directory, open '/package.json'

npm ERR! enoent and is related to npm not being able to find a file.
npm ERR! enoent

Should I run the docker image in the root folder of my project and the entrypoint will execute any command I pass to it?

cheers.

Hi,

You need to mount your current folder into the image
docker run -v $(pwd):/home -w /home weboaks/node-karma-protractor-chrome npm test

You should run the image in the root folder of your project. The entrypoint will execute any command you pass to it.

What's the recommended way to install protractor into this image? And for my curiosity, why is it not included as part of the image itself?

Because the (default) user isn't root, I get this:

bash-4.4$ npm install -g protractor
npm WARN checkPermissions Missing write access to /usr/local/lib/node_modules

@simondrabble the recommended way is to add protractor to your devDependencies and install it alongside your project dependencies.
If you want to install protractor globally, you can use the debian-root or alpine-root tags.

[simondrabble]

That should work, thanks! It just seemed weird to me that this image doesn't have "batteries included" like I would expect.

[sylvaindumont]

Most of the time, protractor and karma are installed via depDependencies, and would be installed two times if they were already installed globally. Not including them is the image reduce the image size for these users.

[simondrabble]

Sounds reasonable. Thanks again!

One more qq: where/ how should webdriver be installed? I don't see a way to start it under protractor. You might want to consider adding some more "getting started/ using this image" documentation :)

[sylvaindumont]

On the debian based variants, just use webdriver installed by protractor. On the alpine based variants, this webdriver isn't compatible with musl, and we have to use one already installed in the image (in /usr/bin/chromedriver)
