NeuroDocker install new packages inside the image

[kaurbhupinder]

I managed to minimize Docker image (bids/example) with Neurodocker but I noticed that one new package(curl) is installed inside the minimized image. Why this package is installed because I was expecting Neurodocker will reduce number of packages installed inside the image by removing unnecessary packages.

hi @kaurbhupinder - can you please give more information about the problem? can you share the commands you used to minimize the bids/example image?

[kaurbhupinder]

@kaczmarj I followed the steps given in issue #295 and link is below https://github.com/kaczmarj/neurodocker/issues/295

[kaczmarj]

the method in #295 is a "gentle" way of minimizing an image. it only cleans things out of certain directories, like /opt. programs like curl are installed by apt-get and live under /usr. i made this gentle minimization method in #258 because doing a full minimization (i.e., deleting everything except files caught by the trace) often creates containers that can no longer be used interactively. they can only be used for the commands used during minimization. if you want to prune more than just /opt, you can add more directories to the ndminify call.

if you want to do a full minimization, can you try https://github.com/kaczmarj/neurodocker#minimize-existing-docker-image ?

@kaczmarj thanks for the explanation and I do understand that. I have two doubts:

1. Do Neurodocker deletes unnecessary packages that are present inside the image?
2. For bids/example I checked for original image there is no curl package inside the image. However when I minimised it and noticed that curl package is installed. Any explanation will be much appreciated. Thanks
