CHANGELOG.md

@@ -15,6 +15,9 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 - **Compose label-driven docker-compose trigger configuration** — Added support for container labels to create and scope compose triggers from discovered containers, including `dd.compose.file` / `wud.compose.file` and compose trigger options (`backup`, `prune`, `dryrun`, `auto`, `threshold`).
 - **Compose-file digest update support** — Docker-compose trigger now supports digest-pinned image references in compose files (`image@sha256:...` and `image:tag@sha256:...`) so digest-based services can be updated without dropping pinning.
 
+- **Compose-native auto-compose discovery** — Added `dd.compose.native` / `wud.compose.native` container labels to enable deriving compose file paths from native Compose labels (`com.docker.compose.project.config_files` + `com.docker.compose.project.working_dir`) when `dd.compose.file` is not set. This requires the resolved compose path to exist inside the drydock container (same path context used by `docker compose`).
+- **Watcher-wide compose-native default** — Added `DD_WATCHER_DOCKER_{name}_COMPOSENATIVE=true` to enable compose-native path discovery for all containers watched by a Docker watcher, with per-container `dd.compose.native` still taking precedence.
+
 ### Fixed
 
 - **TrueForge registry default behavior** — Fixed TrueForge registry integration so it works out of the box with default configuration.

 Behavior notes:
 
 - `dd.compose.file` / `wud.compose.file` causes drydock to create (or reuse) a scoped `dockercompose` trigger for that container.
 - That generated compose trigger is set with `requireinclude=true` and auto-appended to the container include list, so it only runs for explicitly associated containers.
+- `dd.compose.native` / `wud.compose.native` enables deriving compose file paths from native Compose labels (`com.docker.compose.project.config_files` and `com.docker.compose.project.working_dir`).
+- Compose-native/automatic detection requires the resolved compose file path to be valid inside the drydock container (same path that `docker compose` uses); if Compose was run from a host-only path, bind-mount that path into drydock at the same location or set `dd.compose.file` explicitly.
+- `DD_WATCHER_DOCKER_xxx_COMPOSENATIVE=true` enables compose-native lookup by default for all containers in that watcher (container label can still override).
 - If `dd.compose.auto` is omitted, normal trigger default applies (`auto=true`).
 
+Troubleshooting path mismatch:
+
+- Symptom: compose-native is enabled, but DryDock cannot resolve/update the compose file.
+- Cause: the path from Compose labels exists on the host, but not inside the DryDock container at the same absolute path.
+- Fix: bind-mount the host compose project path into DryDock using the same container path, or set `dd.compose.file` per container.
+
+Example (host path and container path are identical):
+
+```yaml
+services:
+  drydock:
+    image: codeswhat/drydock:latest
+    volumes:
+      - /var/run/docker.sock:/var/run/docker.sock
+      - /opt/stacks:/opt/stacks
+```
+
+If your stack was started from `/opt/stacks/myapp/docker-compose.yml`, DryDock must also see that file at `/opt/stacks/myapp/docker-compose.yml`.
+
 `dd.*` labels take precedence when both `dd.*` and `wud.*` are present.
