I want to determine what type of installation is in the OCI provided image (base, minimal, etc). It has less than 500 packages so I was assuming minimal - but want to know for certain if possible. The actual image name contains “base” but I thought base would have more packages. Thanks!
You can do:
dnf group list
and then see if you have output similar to below:
Installed Environment Groups:
Minimal Install
that would suggest a minimal install, you can then do:
root@rocky9:~# dnf group info "Minimal Install"

Environment Group: Minimal Install
Description: Basic functionality.
Mandatory Groups:
Core
Optional Groups:
Standard
and you can then do:
dnf group info "Core"
and get a list of which packages are installed. Of course, repositories BaseOS will have more packages than just 500, for example:
root@rocky9:~# dnf list available | grep -ic baseos
770
root@rocky9:~# dnf list installed | grep -ic baseos
291
so on my installation, I have 291 packages from BaseOS, with another 770 available to install. I can also do:
root@rocky9:~# dnf list installed | grep -ic minimal
131
Adding just the BaseOS installed of 291 and the 131 from minimal, is still less than 500. In fact I’ve also done:
root@rocky9:~# dnf list available | grep -ic minimal
22
which means most likely after installation, I removed packages that I didn’t want on my system. I also have packages from AppStream also installed, because my system is no longer a minimal, since I installed the Development Tools group.
That at least will give you an idea of how to check the image was created and what type it is.
Thank you

I have no installed env groups?
Oddly, dnf group list --installed returns nothing.
Core is mandatory just like on yours, standard is optional just like yours.
Doesn’t dnf group info “Core” just show me what groups are in core? or does it show me the groups that I have installed?
Other output:
[rocky@rocky-9 ~]$ dnf list available | grep -ic baseos
827
[rocky@rocky-9 ~]$ dnf list installed | grep -ic baseos
31
[rocky@rocky-9 ~]$ dnf list available | grep -ic minimal
22
It’s a bit of a customized install. The images are currently built using Kickstart, though we’re moving them to Kiwi soon.
