Symptom & Impact

Container deployments fail because image pulls time out.

Environment & Reproduction

Common behind strict proxies or deep inspection gateways.

podman pull container-registry.oracle.com/os/oraclelinux:10
systemctl status podman
cat /etc/containers/registries.conf

Root Cause Analysis

TLS interception, DNS latency, firewall egress limits, or stale trust store cause failures.

Quick Triage

Check DNS, TLS trust, and registry reachability.

curl -Iv https://container-registry.oracle.com
getent hosts container-registry.oracle.com
firewall-cmd --list-all

Step-by-Step Diagnosis

Inspect podman debug output and proxy inheritance.

podman --log-level=debug pull container-registry.oracle.com/os/oraclelinux:10
systemctl show --property=Environment podman
journalctl -u podman -n 80

Solution – Primary Fix

Set proxy and CA trust correctly, then retry pull.

update-ca-trust
export HTTPS_PROXY=http://proxy.internal:3128
podman pull container-registry.oracle.com/os/oraclelinux:10

Solution – Alternative Approaches

Mirror required images internally for stable access.

podman login registry.internal
podman pull registry.internal/oraclelinux:10

Verification & Acceptance Criteria

Pull succeeds consistently and image is usable.

podman images | grep oraclelinux
podman run --rm container-registry.oracle.com/os/oraclelinux:10 cat /etc/os-release

Rollback Plan

Remove proxy and trust changes if they conflict with policy.

unset HTTPS_PROXY
rm -f /etc/pki/ca-trust/source/anchors/proxy-ca.crt
update-ca-trust

Prevention & Hardening

Standardize proxy and trust bundle settings across container hosts.

grep -R proxy /etc/systemd/system/podman* -n || true
systemctl daemon-reload
