# GreptimeDB Alpine Package

Builds `greptime` from the upstream source release and packages OpenRC service
subpackages plus `/etc/greptimedb` defaults.

Build command:

```sh
cargo build --profile nightly --locked --bin greptime --features servers/dashboard
```

## Runtime Layout

Installs `/usr/bin/greptime` and component OpenRC packages:

- `greptimedb-docs`: upstream configuration examples and reference files from
  `config/`
- `greptimedb-standalone-openrc`: `greptime standalone start`
- `greptimedb-metasrv-openrc`: `greptime metasrv start`
- `greptimedb-datanode-openrc`: `greptime datanode start`
- `greptimedb-flownode-openrc`: `greptime flownode start`
- `greptimedb-frontend-openrc`: `greptime frontend start`

Default TOML files are installed in `/etc/greptimedb`. Standalone ports:

- `127.0.0.1:4000`: HTTP API and dashboard
- `127.0.0.1:4001`: gRPC
- `127.0.0.1:4002`: MySQL
- `127.0.0.1:4003`: PostgreSQL

Configs bind to localhost by default. Upstream config examples are in
`/usr/share/doc/greptimedb/config`.

## OpenRC Usage

Standalone:

```sh
apk add greptimedb greptimedb-docs greptimedb-standalone-openrc
rc-update add greptimedb.standalone default
rc-service greptimedb.standalone start
```

Distributed components:

```sh
apk add \
  greptimedb \
  greptimedb-metasrv-openrc \
  greptimedb-datanode-openrc \
  greptimedb-flownode-openrc \
  greptimedb-frontend-openrc
```

Wrapper settings in `/etc/conf.d/greptimedb.<component>`:

- `GREPTIMEDB_CONFIG`: config file path passed with `-c`
- `GREPTIMEDB_LOG_DIR`: component log directory passed with `--log-dir`
- `GREPTIMEDB_DATA_HOME`: data directory passed with `--data-home` where the
  component supports it
- `GREPTIMEDB_WAL_DIR`: datanode WAL directory passed with `--wal-dir`
- `GREPTIMEDB_OPTS`: extra component arguments appended after package defaults
- `GREPTIMEDB_GLOBAL_OPTS`: arguments inserted before the component command
