bitflicker64 opened a new pull request, #3056:
URL: https://github.com/apache/hugegraph/pull/3056
## Purpose of the PR
- Part of #3043 (Chunk 10)
- Follow-up to #3047 (added `-d` flag to PD/Store startup scripts) and
#3051/#3052 (Docker entrypoint supervision + HEALTHCHECK)
Documents the new `-d true|false` daemon flag and the Docker-native process
supervision model introduced in the preceding PRs.
## Main Changes
**`hugegraph-pd/README.md`:**
- Add `-d DAEMON` to the startup options signature
- Document: daemon mode (`true` = daemon, `false` = foreground; default:
`true`); set to `false` under Docker or a process supervisor
**`hugegraph-store/README.md`:**
- Same additions as PD
**`hugegraph-server/hugegraph-dist/docker/README.md`:**
- Add section explaining HEALTHCHECK endpoints (`:8080/versions`,
`:8620/v1/health`, `:8520/v1/health`) and the Java process supervision model
- Note that the cron-based monitor (`-m true`) is for VM/bare-metal only,
not Docker
## Verifying these changes
- [x] Need tests and can be verified as follows:
- `docker inspect <image> | grep -A5 Healthcheck` — confirms HEALTHCHECK
is present
- `docker stop <container>` — container exits cleanly (SIGTERM forwarded
to Java)
- `kill -9 <java-pid>` inside container — container exits, restart policy
fires
## Does this PR potentially affect the following parts?
- [ ] Dependencies
- [ ] Modify configurations
- [ ] The public API
- [ ] Other affects
- [x] Nope
## Documentation Status
- [x] `Doc - Updated` (in-repo README files only; `hugegraph-doc` follow-up
is tracked separately)
