Summary:

It's a modified version of TailorBrands' version, with the following changes:

• Base image is now pulled from official node:latest image, making the node easily interchangeable with older versions by just editing a single line.
• Image is now inclusive with node-gyp dependencies for rebuilding libraries, so installed npm packages (thru Dockerfile, or real-time dev/prod) will build flawlessly
• Image is also inclusive of 'sharp' npm package, npm-installed as a global library
• Added tweaks that:
  • Allowed installation of global package in NPM (thru chown & sudo)
  • Allowed requiring of globally installed packages (thru ~/.bashrc fix)

Contents:

• node:latest @ v8.8.1; 5.4.2
• vips @ vips-8.5.5
• gcc & g++ for node-gyp
• npm install --global of 'sharp' library
• chown to allow that npm --global install
• ~/.bashrc fix to allow requiring of globally installed packages

Setup

• docker pull xemasiv/node-env
• docker run -it -d xemasiv/node-env
• docker container ls --> to get the container name
• docker attach <container_name>

Testing (now logged in as root):

• node -v && npm -v && vips -v
• node --> takes you to node cli
• require('sharp') --> should return the sharp function itself.

Usage

• attach your project directory as a docker volume.
• expose a port to make your project accessible from the host machine & outside world.
• this gives you an environment where vips and 'sharp' library is already accessible.

Credits:

• Check the Dockerfile for the sources and the things you can modify.
