시나리오
A scenario that narrows down the root cause, centered on comparing the name-resolution path of the host and the container, in the situation of DNS resolving on the host but not inside the container.
DNS resolves on the host but not inside the container
A typical failure that appears when the container runtime's DNS settings and search domains diverge.

점검 체크리스트
- Summarize the current impact and the last known change.
- Collect direct evidence from logs, runtime state, and configuration before changing anything.
- Separate immediate recovery from permanent prevention work.
복구와 재발 방지
Choose the smallest safe recovery action first, then record the prevention work that reduces repeat incidents.

They may use different resolver files, search domains, runtime injection, or network namespaces even on the same node.
Compare resolver config, search domains, upstream nameserver reachability, and runtime overrides before changing DNS records.
