Container Trees
Singularity Python has functions to visualize containers, meaning creating container trees and comparing containers. All of our different code examples are here.
What's inside that container? Right now, the main way to answer this question is to do some equivalent of ssh. shub provides a command line function for rendering a view to (immediately) show the contents of an image (folders and files) in your web browser.
shub will render the guts of any Docker image, even if it's not currently on your system. You don't need to have Docker installed for this to work.
shub --image docker://ubuntu:latest --tree
You can also do this with a local image, it will work equivalently:
shub --image ubuntu.img --tree
Each of these commands will open up something that looks like this:
An interactive demo is also available, and see the example for updates.
Do you have sets of containers or packages, and want to cluster them based on similarities?
We have examples for both deriving scores and producing plots like the above, see examples/visualize/tree/package_tree
What do two containers have in common, in terms of files and folders? shub provides a command line function for rendering a view to (immediately) show the similarity between to container images:
shub --images centos.img,ubuntu.img --simtree --debug
We can also compare a local image to a Docker image:
shub --images docker://ubuntu:latest,/home/vanessa/Desktop/ubuntu.img --simtree --debug
Or two Docker images:
shub --images docker://ubuntu:latest,docker://centos:latest --simtree
If you need output for any of the following, you can add the --debug argument. Note that when generating docker comparisons, the back end is obtaining the layers, creating the images, importing and packaging, so the result is not instantanous.
An interactive demo is also available.
What files and folders differ between two containers? What does it look like if I subtract one image from the second? shub provides a command line tool to generate a visualization to do exactly this.
shub --subtract --images docker://ubuntu:latest,docker://centos:latest
As with simtree, this function supports both docker and singularity images as inputs.
An interactive demo is also available.
