docker-image_optim

A docker image giving the built version of the best image optimizing CLI apps together with image_optim to rule them all

Credits

95% of this work it's from rhardih's first attempt at dockerizing this project.

Changes

• Maintaining an additional Dockerfiles with fewer layers for production purposes
• creating more layers, so if you need to test different versions you can avoid full rebuilds.
• Versions have been bumped, and ordered alphabetically

Minimal usage

Execute image_optim in your current dir:

docker run --rm -ti -v $(pwd):/images/ colthreepv/docker-image_optim image_optim -r .

How To Use

docker run --rm -ti \
  # Add whatever image directory you like
  # -v $(cd && cd images && pwd):/images/ \
  -v $(pwd)/config:/root/.config/ \
  colthreepv/docker-image_optim sh

Then a simple cd /images && image_optim -r . would optimize all the images in the mounted path.

How to Build

docker build -t image_optim . and (after a while) you can run your custom-built image

docker run --rm -ti \
  # Add whatever image directory you like
  # -v $(cd && cd images && pwd):/images/ \
  -v $(pwd)/config:/root/.config/ \
  docker-image_optim sh

Configuration

A demo configuration (LOSSY!) can be found in config/image_optim.yml, all the options are listed here

Footprint

A serious shrink in footprint has been achieved squashing all the RUN layers into one.
The drawback is having to maintain 2 Dockerfiles
