Symptom & Impact

Podman Quadlet services fail to start at boot on CentOS Stream 9 disrupts services and slows incident response until the root cause is resolved.

Environment & Reproduction

Quadlet-generated systemd units error out because referenced volumes or networks are missing.

systemctl --user status .service
ls -l /etc/containers/systemd/

Root Cause Analysis

Misalignment between container configuration and CentOS Stream 9 defaults causes the failure path described above.

Quick Triage

Confirm package state, service status, and recent changes before deeper diagnostics.

systemctl status
rpm -qa | grep -i 
journalctl -p err -b --no-pager | tail -100

Step-by-Step Diagnosis

Capture detailed logs, configuration deltas, and runtime state to isolate the failing component.

journalctl --user -u .service -n 200
/usr/libexec/podman/quadlet -dryrun

Solution – Primary Fix

Apply the targeted configuration change and restart the relevant services to restore expected behavior.

sudo /usr/libexec/podman/quadlet -dryrun
sudo systemctl daemon-reload
sudo systemctl enable --now .service

Solution – Alternative Approaches

Use podman generate systemd for legacy workflows during migration.

Verification & Acceptance Criteria

Validate the fix with deterministic checks and ensure no regressions in dependent services.

systemctl status .service
podman ps -a

Rollback Plan

Revert configuration and restart services to return to the previous known-good state.

systemctl disable .service
rm /etc/containers/systemd/.container

Prevention & Hardening

Pin Podman versions and lint .container files in CI.
