error importing container with a name containing a colon

[gzcwnk]

Steps to reproduce

When I made a container name I used a : this caused the following error,

[root@vuwunicoslurmt1 rocky8-27-8-2024]# podman save rocky8:8.x > rocky8:8.x.tar

[root@vuwunicoslurmt1 rocky8-27-8-2024]#
[root@vuwunicoslurmt1 rocky8-27-8-2024]#
[root@vuwunicoslurmt1 rocky8-27-8-2024]# wwctl container import rocky8:8.x.tar rocky8:8.x

renaming it,

mv rocky8:8.x.tar rocky8-8.x.tar
[root@vuwunicoslurmt1 rocky8-27-8-2024]# wwctl container import rocky8-8.x.tar rocky8:8.x

and it seems to work fine, (nodes boot Ok off it)

Error message

@JasonYangShadow can you investigate this?

[JasonYangShadow]

it is an upstream issue, colon is kind of restricted symbol inside the file/path name.
https://github.com/containers/image/blob/31d4ad14fe4da8ef3969ff67297831ab291c76f1/docker/archive/transport.go#L65
refString here is the abs path, e.g. /home/vagrant/rocky8:8.x.tar, it'll treat the file name as an image and a tag by splitting based on :.
Also it is not recommended to create tar file using colon in the name
