Dependency visualisation of an RPM-based installation (a system, an image, etc.)
The script requires the following dependencies on your system:
$ sudo dnf install graphviz podman python3-jinja2
Just tell the script what you what to show, how you want to see it, and where you want to save it. Like this:
$ ./rpm-showme WHAT HOW WHERE
To look at the Fedora 30 container base image, run:
$ ./rpm-showme fedora:30 graph output.svg --sizes
... which produces a graph of all packages in the fedora:30 container image including sizes of all individual packages and some basic clustering. Clicking on a package highlights its relations to other packages.
See the original Fedora 30 container image graph and try interacting with it!
To look at your own Fedora system, run:
$ ./rpm-showme / graph output.svg
You can also look at an arbitrary DNF installation:
$ mkdir /tmp/cowsay
$ sudo dnf --installroot /tmp/cowsay --releasever 30 install cowsay
$ ./rpm-showme ./ graph output.svg
Graphs can be simplified by merging multiple nodes (packages) into a single node (group). This is useful, for example, when visualizing an httpd installation on top of the Fedora base container image.
Example:
$ ./rpm-showme asamalik/fedora-httpd:f30 graph test.svg --sizes --group-container "Fedora 30 Base Image" fedora:30
See the original httpd on top of the Fedora base image graph.
The above example might be better shown as a directed graph:
$ ./rpm-showme asamalik/fedora-httpd:f30 directed-graph test.svg --sizes --group-container "Fedora 30 Base Image" fedora:30
See the original directed graph of httpd. Again, it's interactive!
A simple list of packages in the standard output:
$ ./rpm-showme fedora:30 list
acl
alternatives
audit-libs
basesystem
bash
...
Just print out the total size of all packages:
$ ./rpm-showme fedora:30 size
274.2 MB
An HTML table comparing multiple installations:
$ ./rpm-showme fedora:30 report report.html --name "Fedora 30 base image" --add "httpd" httpd:f30
See the report.html and report-sizes.html generated with the --sizes option.
