docker-imagemagick

Docker with ImageMagick tools

build

git clone https://github.com/gustavopaes/docker-imagemagick.git
cd docker-imagemagick/
docker build -t docker-imagemagick .

run command

You need mount volume where your target image is:

docker run -v /home/gpaes/images/:/temp -w /temp docker-imagemagick convert -quality 70 original.png converted.jpg

The converted.jpg will be created on the same original.png path.

If you are in the same target image path, you can run:

docker run -v `pwd`:/temp -w /temp docker-imagemagick convert -quality 70 original.png converted.jpg
