Docker container for corsika

This will build a docker container for CORSIKA

To build you execute docker build like this:

docker build --build-arg CORSIKA_PASSWORD=the_password_you_received -t <useful container name e.g: corsika-iceact:75600> .

with the config given in config.h. The install directory is /opt/corsika-<version>/run

It was created with the following options:

options:   TIMEAUTO VOLUMEDET QGSJETII URQMD 
selection: IACTDIR CERENKOV VIEWCONE BERNLOHRDIR IACT ATMEXT

Currently there are two directories in this repository, containing Dockerfiles for corsika 7.41 and 7.56 each.

Running something in the container

You can get an interactive shell in the docker container with

docker run -it <useful container name you chose before> bash

Add the --rm option to automatically remove the container once it has stopped.

Mount directories

To access your host file system (e.g. for storing results and accessing input cards), you can mount volumes using the -v docker option:

docker run -v /absolute/path/to/data:/data -it <useful container name> bash

File ownership and permissions

To avoid hassle with file permissions and ownership, you should create a docker image, which has the same user, user id and group id as the your user on the host system.

A Dockerfile might look like this:

FROM corsika:75600

RUN useradd --create-home --uid 1000 maxnoe
USER maxnoe
