"runc" versus "containerd" versus "containerd.io"?
i'm sure i will embarrass myself for asking this, but i'm confused
about the relationship on my F30 (branched) system between those three
packages. i can see that they are all container runtime packages, but
i get confused when i run commands to try to understand how they
relate to each other, as they clearly(?) represent alternatives for
container runtimes.
currently, on my system, rpm reports that only containerd.io is
installed:
$ rpm -q runc
package runc is not installed
$ rpm -q containerd
package containerd is not installed
$ rpm -q containerd.io
containerd.io-1.2.4-3.1.fc29.x86_64
however, the man page that works is "man containerd", not "man
containerd.io".
also, even though rpm suggests that, as packages, containerd.io is
installed and containerd is not, dnf repoquery seems to report the
opposite:
$ dnf repoquery -l containerd.io

$
$ dnf repoquery -l containerd
Last metadata expiration check: 0:30:22 ago on Fri 29 Mar 2019
06:32:46 AM EDT.
/etc/containerd
/etc/containerd/config.toml
/usr/bin/containerd
/usr/bin/containerd-shim
/usr/bin/ctr
.... etc etc ...
finally, while "dnf info runc" reports that there is a runc package,
trying to install unsurprisingly produces:
$ sudo dnf install runc
... snip ...
Package containerd.io-1.2.4-3.1.fc29.x86_64 is already installed.
... etc ...
so i'm sure there is a relationship involving provides and conflicts
or something of the sort, i'm just confused as to what's happening
here. (if there is a better forum for a question like this, by all
means, let me know.)
