I installed the Minione. After 5 minutes, I wanted to create an image by following this video.
but I am getting an error as below. There are two “/ /” signs, I think the script installation in the repo is doing it wrong. I did the installation on ubuntu focal.
/var/lib/one//datastores/1/bdbe98369d7776c951cca26e4adeed8f'
Can you post the full error log ?
my setup input
Path in OpenNebula server or URL
docker://nginx:stable-alpine?size=1024&filesystem=ext4&format=raw&distro=alpine
this full error log.

That video was made on an old version of OpenNebula, if you are interested in using images from dockerhub, we actually have it integrated as a marketplace. You will get on top the benefits of an auto-contextualized image.
In fact, the reason for using opennebula is to make it easy to manage firecracker machines. If there is an explanation in the rootfs creation section for Firecracker, I can look there as well.
It seems your URL is not properly build, you’re using:
docker://nginx:stable-alpine?size=1024&filesystem=ext4&format=raw&distro=alpine
Note that you’re setting the tag as name:tag. If you take a look at the official documentation you have to pass the tag as an URL argument:
docker://<image>?size=<image_size>&filesystem=<fs_type>&format=raw&tag=<tag>&distro=<distro>
As @dclavijo said, the video is based on and old version of OpenNebula, so the format used differs with the current implementation.
@cgonzalez thank you so much, yeah it work
