# Get Dockerfile of a bioconda package

Bioconda packages have associated containers images. E.g. bioconductor-csaw has the image quay.io/biocontainers/bioconductor-csaw.

I would like to customize the image, in particular, I would like to add rstudio.

It is possible to get the Dockerfile associated to the image of a bioconda package?

How do you suggest to proceed to customize the image?

mulled-build build 'bioconductor-csaw=someversion--somebuildnumber' 'someotherpackage=someversion--somebuildnumber' ...

That probably requires setting the CONDA_IMAGE environment variable. Bioconda currently sets that to quay.io/dpryan79/mulled_container:latest.
