Greptile Summary

This PR corrects the commented-out RSSHub example configuration in the Docker Compose file and updates documentation to match.

Changes:

• Port correction: Updates RSSHub's exposed port from 3000 to 1200, matching its actual default. Reflected in docker-compose.yml and both English and Chinese documentation examples.
• Network access: Adds public_access network to the RSSHub service, enabling outbound internet access (the previous service_only network is internal-only, which would have silently broken feed fetching).
• ALLOW_PORTS hint: Adds a commented environment variable ALLOW_PORTS=1200 to the TTRSS service, since TTRSS restricts port access by default (allowing only 80/443) and needs this configuration to reach port 1200.
• Image tag note: Adds a comment about the :chromium-bundled image variant for routes that require Puppeteer.

All changes are to a commented-out example, so no running services are affected. Documentation updates are consistent across both languages.

Confidence Score: 5/5

• Safe to merge — all changes are correct bug fixes to a commented-out example configuration with consistent documentation updates.
• All four claimed fixes are verified as accurate: (1) RSSHub's default port is indeed 1200; (2) adding public_access network enables outbound internet access as needed; (3) ALLOW_PORTS=1200 is correct guidance for TTRSS port restrictions; (4) the image tag comment is helpful and accurate. Since the entire rsshub service block remains commented out, no running services are affected. Both English and Chinese documentation are updated consistently.
• No files require special attention.

docker-compose.yml (1)

83-83: Consider removing public_access from RSSHub if external access is not required.

The commented RSSHub configuration includes the public_access network, but since TTRSS communicates with RSSHub via service.rsshub:1200 on the internal Docker network, only the service_only network is necessary. The public_access network is intended for external access (e.g., TTRSS UI), which RSSHub doesn't need unless you plan to expose it externally. Removing it would keep the configuration minimal and focused.

service_only network by deleting the commented or active "- public_access" line
so RSSHub is not bound to the external network unless you intentionally need
external exposure.
