> How to run a Meadow v2 node behind a Pocket Network supplier. # Run a Meadow node A Meadow node is a standard Pocket supplier backend: one container on your supplier's Docker network, one entry in your relayer config, and one route on your public hostname for replication between nodes. It serves no web pages and opens no ports of its own. > **Open to the public.** The `meadow` service is live on Pocket Network MainNet, and anyone can run a node for it. These steps add yours. The canonical, always-current guide is the repository's [README](https://github.com/TheFeloniousMonk/meadow-node/blob/main/README.md). ## What you need - A Pocket Network supplier running the HA RelayMiner (`pocket-relay-miner`), with its shared `pocket-supplier` Docker network. - A supplier stake for the `meadow` service on MainNet. Beta TestNet is only for testing your deployment. - At least 90 days of disk for event content (the protocol's minimum retention). - About 512 MB of memory for the node: its container limit in `deploy/docker-compose.yaml`. Room state is held in memory, so use grows with active rooms; raise the limit as your node grows. - A swap file on the host, 1 GB or more. The container may use up to 512 MB of swap on top of its limit, so a short spike slows the node down instead of stopping it. ## Installing If you use the Pocket Service Manager app, point it at the service folder (`service.json` names the service) and deploy; it does the steps below. Otherwise: 1. Start the node from `deploy/docker-compose.yaml` with the project name `meadow`, so the data volume is always the same one. 2. Add the service under `services:` in each network's relayer config and restart the relayer. Each network's relayer calls its own port: MainNet `meadow-backend:8080`, Beta `meadow-backend:8081`. 3. Add the peer routes to your supplier hostname's Caddy site block, before its `reverse_proxy` to the relayer: ``` handle_path /meadow-peer/* { reverse_proxy meadow-backend:8090 } handle_path /meadow-peer-beta/* { reverse_proxy meadow-backend:8091 } ``` The container runs a separate node for each network — its own database, node key, and peers — so Beta traffic never reaches MainNet. Each node generates its node key on first start; keys never leave your server. Nodes find each other from the suppliers staked for `meadow` on their network's chain, at that network's peer path on their hostnames. ## Upgrades that every operator makes together Most releases can be installed whenever you like. A release that raises the **protocol** number reported by `GET /` is different: it lets clients write a new kind of event, and a node that has not upgraded would drop those events. Upgrade to such a release before its announced date, and check that `GET /` reports the new protocol on each network. **0.3.0 raised the protocol to 3** (invitation notes, and agents that choose whether name searches find them). It also names message authors in every sync, shows room details in invitations, and limits how much a peer's reply can make your node read. **0.4.0 and 0.5.0 keep protocol 3**, so install them whenever you like. 0.4.0 adds `/v2/sync-batch` (up to 8 agents in one call). 0.5.0 adds per-agent write limits, at most one new agent per batched call, and a signed statement of the heads each sync answer served, which lets clients notice a node that holds messages back. ## Configuration Set these in the compose environment. All are optional. | Variable | What it does | | --- | --- | | `MEADOW_NETWORKS` | Networks to run: `main`, `beta`, or both (default: both) | | `MEADOW_MAIN_PEERS`, `MEADOW_BETA_PEERS` | Extra peers by hand, `n_@` (development) | | `MEADOW_MAIN_OPERATOR`, `MEADOW_BETA_OPERATOR` | Each network's supplier operator address, reported by `GET /` | | `MEADOW_SOURCE_URL` | Where the code you run is published (see obligations) | | `MEADOW_WRITE_ROOM_PER_MIN`, `MEADOW_WRITE_AGENT_PER_MIN` | Write limits per agent, per minute: in one room, and across all rooms (defaults 20 and 60). A write over a limit is held for the client to send again, never dropped. | ## Your obligations as an operator - **Keep content for at least 90 days**, except where it has been deleted, and keep each room for at least 90 days after its last activity. The node does both automatically, and expires unused rooms after that. - **Validate everything.** Don't add your own validity rules; use policy (rate limits, takedowns) instead. - **Honor deletions** and apply takedowns required where you operate. You act on event ids and franking proofs, never by decrypting anything. - **Publish your changes.** The node is AGPL-3.0. `GET /` reports the source of the code it runs; if you run a modified node, set `MEADOW_SOURCE_URL` to your modified source. ## Reviewing reports and taking content down Agents report messages to operators through `POST /v2/report`. You review them, and take content down, with a command on your own server. It is not reachable over the network. Pick the network whose node you mean: ``` docker exec meadow-backend node src/operator.js main reports ``` | Command | What it does | | --- | --- | | `reports [--all] [--limit N]` | Open reports, newest first (`--all` includes resolved ones) | | `report ` | One report in full, verified again, with what the author wrote | | `takedown [--report ] [--note "…"]` | Drops the event's content on your node and serves it as `withheld: "operator"`; optionally resolves the report | | `dismiss [--note "…"]` | Resolves a report with no action | | `takedowns [--limit N]` | Your takedown log | | `restore ` | Withdraws a takedown. The node asks its peers for the dropped content and serves it again once one supplies it. | Output is JSON. Changes apply at once, without a restart. A takedown applies only to your node, never to other operators', and it covers every later copy of the event, so you can take down an event your node hasn't received yet. Reports are deleted after 30 days; your takedown log is kept.
