How to check on Satellite or Capsule where a package is served from?

Environment

Red Hat Satellite or Capsule 6

Issue

• Fetching a package from Satellite or Capsule hits some issues.
• We need to understand where the package is served from - from a disk if already downloaded, or from some remote source (and which one)?

Resolution

Create explain_where_to_fetch_package.py file with this content:

from pulpcore.content import Handler
from pulpcore.content.handler import PathNotResolved
import os

if  'URI' not in os.environ.keys():
    print("no URI path provided, please re-run with OS variable URI set")
    quit()

path = os.environ['URI']  # example: 'RedHat/Library/content/dist/rhel9/9/x86_64/baseos/os/Packages/s/sos-4.8.2-2.el9_5.noarch.rpm'

h = Handler()
try:
    distro = h._match_distribution(path)
except PathNotResolved:
    print(f"path {path} is not known, ensure you provide a valid URI without the server name")
    quit()

rel_path = path.lstrip("/")
rel_path = rel_path[len(distro.base_path) :]
rel_path = rel_path.lstrip("/")

ca = distro.publication.published_artifact.select_related(
                        "content_artifact",
                        "content_artifact__artifact",
                        "content_artifact__artifact__pulp_domain",
                    ).get(relative_path=rel_path).content_artifact

if ca.artifact:
    print(f"package is downloaded locally at /var/lib/pulp/media/{ca.artifact.file}, expected size: {ca.artifact.size} sha1sum: {ca.artifact.sha1} sha256sum: {ca.artifact.sha256}")
else:
    remote_artifacts = ca.remoteartifact_set.select_related(
            "remote"
    ).order_by_acs()
    
    print(f"package is not local, can be downloaded from {len(remote_artifacts)} locations, printing first up to 3:")
    for ra in remote_artifacts[:2]:
        if ra.url.startswith(ra.remote.url):
            warn = ""
        else:
            warn = f" DIFFERENT FROM Remote object url {ra.remote.url}!" 
        print(f"  {ra.url}{warn}")

Execute it with proper URI value:

cat explain_where_to_fetch_package.py | sudo -u pulp URI='MyOrg/DEV_LE/MY_CV/content/dist/rhel9/9/x86_64/baseos/os/Packages/s/sos-4.8.1-1.el9_5.noarch.rpm' PULP_SETTINGS='/etc/pulp/settings.py' DJANGO_SETTINGS_MODULE='pulpcore.app.settings' pulpcore-manager shell

Example output:

package is downloaded locally at /var/lib/pulp/media/artifact/04/2d43e4f70945ffc72ecba4739cf382dafb559bb5060b10ec9073f23a5bfed8, expected size: 1223606 sha256sum: 042d43e4f70945ffc72ecba4739cf382dafb559bb5060b10ec9073f23a5bfed8

or:

package is not local, can be downloaded from 1 locations, printing first up to 3:
  https://cdn.redhat.com/content/dist/rhel9/9/x86_64/baseos/os/Packages/s/sos-4.8.1-1.el9_5.noarch.rpm

Warning: For Satellite/Capsule 6.14 or older, run rather

grep -v content_artifact__artifact__pulp_domain explain_where_to_fetch_package.py | ..
