jcgoran/cr2hdr repository overview

⁠Dockerfile for cr2hdr

This is a simple Dockerfile for installing the cr2hdr tool for processing Magic Lantern dual ISO images (source repo⁠). I couldn't find a simple installer for GNU/Linux, so after some trial and error this is is the end result.

⁠How to install

The image from Dockerhub⁠:

docker pull jcgoran/cr2hdr

Building the Docker image from this repo:

git clone https://github.com/JCGoran/cr2hdr-docker
docker build cr2hdr-docker

⁠How to use

Once you've installed it, you can run cr2hdr as follows:

docker run --rm -ti -v "$(pwd):/data" jcgoran/cr2hdr /bin/bash -c "cr2hdr [OPTIONS] [IMAGE_NAME(S)]"

As the above is lengthy, you may want to make a bash/csh/whatever shortcut, by putting something like the below in one of your shell dotfiles:

cr2hdr(){
    args="$@"
    docker run --rm -ti -v "$(pwd):/data" jcgoran/cr2hdr /bin/bash -c "cr2hdr $args"
}

Then to invoke it, you can just run cr2hdr from a shell (note: it will only work for images in the current directory and below, i.e. going up (../ or similar) or using absolute paths will not work).
