I’m trying to figure out what’s the difference between official Ubuntu container images from ubuntu: repository and those from community images: repository. Community images are built using distrobuilder from .yaml files found here.
Where can I find .yaml files for official Ubuntu container images? Are they somewhere at https://cloud-images.ubuntu.com ?
Hi,
The ubuntu*: images are built by Canonical’s CPC team and are the official Ubuntu images (both container and VM types).
They don’t use distrobuilder to build them AFAIK, but separate tooling.
The main differences between them and the community images that I’ve observed are that the official Ubuntu images include sshd, cloud-init and snapd installed by default.
There’s also the ubuntu-minimal: variants that have fewer packages installed.
Thank you. Since comparing YAML files is impossible, I tried listing all installed packages in ubuntu:22.04 and images:ubuntu/jammy/cloud containers using command:
apt list --installed | cut -d/ -f1 > 1st_file.txt
Then I did a diff on two output files:
diff --changed-group-format='%>' --unchanged-group-format='' 1st_file.txt 2nd_file.txt
Official Ubuntu 22.04 container (regular one, not minimal) has way more packages installed compared to community version. This explains why they may behave slightly differently during use.
