Building images with container-suseconnect takes way too long...

[Gagrio]

Hi, I noticed that building images with container-suseconnect can take a very long time

Example:

• Dockerfile:

  
  # syntax=docker/dockerfile:experimental
  FROM registry.suse.com/suse/sle15:latest

ENV ADDITIONAL_MODULES sle-module-basesystem,sle-module-development-tools

RUN --mount=type=secret,id=SCCcredentials,required \ zypper --non-interactive up && \ zypper --non-interactive in git

- Build command:
`DOCKER_BUILDKIT=1 docker image build --pull --secret id=SCCcredentials,src=SCCcredentials -t reg-build .` (already had credentials pulled)

[+] Building 3386.3s (4/6)
[+] Building 3386.5s (4/6)
[+] Building 338[+] Building 4206.6s (4/6)
[+] Building 4551.4s (5/6)

In this particular case the build failed because I had not add the `sle-development-tools` module, but still took about an hour to do so, spending most of it to build and add repos...

Thank you!

I'm not able to reproduce this.

One potential issue could be the zypper up command, which triggers packages to be installed, and this might take a while.

container-suseconnect connects to the SCC API and refreshes the repositories, this is often fast (few seconds). From there, zypper refreshes repositories and installs packages, which can take time.
