# Self-hosted Open-Meteo overlay — serves the ERA5 archive locally so the app is
|
|||
|
|
# off the rate-limited public archive API. Enable it only on the self-hosting host:
|
|||
|
|
#
|
|||
|
|
# docker compose -f docker-compose.yml -f docker-compose.openmeteo.yml up -d
|
|||
|
|
#
|
|||
|
|
# The hourly .om data (copernicus_era5_land 0.1° + copernicus_era5 0.25°) lives in
|
|||
|
|
# OBJECT STORAGE, surfaced on the host as a local directory by an rclone FUSE mount
|
|||
|
|
# (a host systemd unit — see deploy/openmeteo/README.md). OM_DATA_DIR points the
|
|||
|
|
# containers at that mount; it defaults to ./data/om-archive so a local smoke test
|
|||
|
|
# works against a plain directory. Object storage is never bind-mounted into the app
|
|||
|
|
# — only Open-Meteo reads it; the app just talks HTTP to open-meteo-api and keeps its
|
|||
|
|
# own small daily-per-cell parquet cache.
|
|||
|
|
#
|
|||
|
|
# One-time backfill (writes ~1–1.5 TB of .om to object storage — run once before the
|
|||
|
|
# app is flipped over): `make om-backfill`.

|||

|
services:
|
|||
|
|
# Serves /v1/archive on the compose network. No host port: only `app` reaches it,
|
|||
|
|
# as http://open-meteo-api:8080. Reads .om from the object-storage mount, on demand
|
|||
|
|
# for any point, returning JSON byte-identical to the public archive API.
