Adds a new [.mbtiles](https://github.com/mapbox/mbtiles-spec/blob/master/1.3/spec.md) backend, without the grid support. Uses extensive tile content detection, i.e. if the content is gzipped, png, jpeg, gif, webp. From CLI, can be as easy as adding a path to a directory that contains a .mbtiles file (works just like pmtiles support) ```bash # All *.mbtiles files in this dir will be published. # The filename will be used as the source ID martin ./tests/fixtures ``` From configuration file, the path can be specified in a number of ways (same as pmtiles) ```yaml mbtiles: paths: # scan this whole dir, matching all *.mbtiles files - /dir-path # specific mbtiles file will be published as mbtiles2 source - /path/to/mbtiles2.mbtiles sources: # named source matching source name to a single file pm-src1: /tmp/mbtiles.mbtiles # named source, where the filename is explicitly set. This way we will be able to add more options later pm-src2: path: /tmp/mbtiles.mbtiles ``` Fixes #494

|
||
If you are using macOS and [Homebrew](https://brew.sh/) you can install martin using Homebrew tap.
|
||
|
||
```shell
|
||
brew tap urbica/tap
|
||
brew install martin
|
||
```
|
||
|
||
You can also use [official Docker image](https://hub.docker.com/r/maplibre/martin)
|
||
|
||
```shell
|
||
docker run -p 3000:3000 -e DATABASE_URL=postgresql://postgres@localhost/db maplibre/martin
|
||
```
|
||
|
||
## Usage
|
||
|
||
Martin requires a database connection string. It can be passed as a command-line argument or as a `DATABASE_URL` environment variable.
|
||
|
||
```shell
|
||
martin postgresql://postgres@localhost/db
|
||
```
|
||
|
||
Martin provides [TileJSON](https://github.com/mapbox/tilejson-spec) endpoint for each [geospatial-enabled](https://postgis.net/docs/postgis_usage.html#geometry_columns) table in your database.
|
||
|
||
## API
|
||
|
||
When started, martin will go through all spatial tables and functions with an appropriate signature in the database. These tables and functions will be available as the HTTP endpoints, which you can use to query Mapbox vector tiles.
|
||
|
||
| Method | URL | Description |
|
||
|--------|------------------------------------|---------------------------------------------------------|
|
||
| `GET` | `/` | Status text, that will eventually show web UI |

|
||
| `GET` | `/health` | Martin server health check: returns 200 `OK` |
|
||
|
||
## Using with MapLibre
|
||
[MapLibre](https://maplibre.org/projects/maplibre-gl-js/) is an Open-source JavaScript library for showing maps on a website. MapLibre can accept [MVT vector tiles](https://github.com/mapbox/vector-tile-spec) generated by Martin, and applies [a style](https://maplibre.org/maplibre-gl-js-docs/style-spec/) to them to draw a map using Web GL.
|
||
|
||
You can add a layer to the map and specify Martin [TileJSON](https://github.com/mapbox/tilejson-spec) endpoint as a vector source URL. You should also specify a `source-layer` property. For [Table Sources](#table-sources) it is `{table_name}` by default.
|
||
|
||
|
||
```js
|
||
map.addLayer({
|
||
id: 'points',
|
||
type: 'circle',
|
||
source: {
|
||
type: 'vector',
|
||
url: 'http://localhost:3000/points'
|
||
},
|
||
'source-layer': 'points',
|
||
paint: {
|
||
'circle-color': 'red'
|
||
},
|
||
});
|
||
```
|
||
|
||
```js
|
||
map.addSource('rpc', {
|
||
type: 'vector',
|
||
url: `http://localhost:3000/function_zxy_query`
|
||
});
|
||
map.addLayer({
|
||
id: 'points',
|
||
type: 'circle',
|
||
source: 'rpc',
|
||
'source-layer': 'function_zxy_query',
|
||
paint: {
|
||
'circle-color': 'blue'
|
||
},
|
||
});
|
||
```
|
||
|
||
You can also combine multiple sources into one source with [Composite Sources](#composite-sources). Each source in a composite source can be accessed with its `{source_name}` as a `source-layer` property.
|
||
|
||
```js
|
||
map.addSource('points', {
|
||
type: 'vector',
|
||
url: `http://0.0.0.0:3000/points1,points2`
|
||
});
|
||
|
||
map.addLayer({
|
||
id: 'red_points',
|
||
type: 'circle',
|
||
source: 'points',
|
||
'source-layer': 'points1',
|
||
paint: {
|
||
'circle-color': 'red'
|
||
}
|
||
});
|
||
|
||
map.addLayer({
|
||
id: 'blue_points',
|
||
type: 'circle',
|
||
source: 'points',
|
||
'source-layer': 'points2',
|
||
paint: {
|
||
'circle-color': 'blue'
|
||
}
|
||
});
|
||
```
|
||
|
||
## Using with Leaflet
|
||
|
||
[Leaflet](https://github.com/Leaflet/Leaflet) is the leading open-source JavaScript library for mobile-friendly interactive maps.
|
||
|
||
You can add vector tiles using [Leaflet.VectorGrid](https://github.com/Leaflet/Leaflet.VectorGrid) plugin. You must initialize a [VectorGrid.Protobuf](https://leaflet.github.io/Leaflet.VectorGrid/vectorgrid-api-docs.html#vectorgrid-protobuf) with a URL template, just like in L.TileLayers. The difference is that you should define the styling for all the features.
|
||
|
||
```js
|
||
L.vectorGrid
|
||
.protobuf('http://localhost:3000/points/{z}/{x}/{y}', {
|
||
vectorTileLayerStyles: {
|
||
'points': {
|
||
color: 'red',
|
||
fill: true
|
||
}
|
||
}
|
||
})
|
||
.addTo(map);
|
||
```
|
||
|
||
## Using with deck.gl
|
||
|
||
[deck.gl](https://deck.gl/) is a WebGL-powered framework for visual exploratory data analysis of large datasets.
|
||
|
||
You can add vector tiles using [MVTLayer](https://deck.gl/docs/api-reference/geo-layers/mvt-layer). MVTLayer `data` property defines the remote data for the MVT layer. It can be
|
||
|
||
- `String`: Either a URL template or a [TileJSON](https://github.com/mapbox/tilejson-spec) URL.
|
||
- `Array`: an array of URL templates. It allows to balance the requests across different tile endpoints. For example, if you define an array with 4 urls and 16 tiles need to be loaded, each endpoint is responsible to server 16/4 tiles.
|
||
- `JSON`: A valid [TileJSON object](https://github.com/mapbox/tilejson-spec/tree/master/2.2.0).
|
||
|
||
```js
|
||
const pointsLayer = new MVTLayer({
|
||
data: 'http://localhost:3000/points', // 'http://localhost:3000/table_source/{z}/{x}/{y}'
|
||
pointRadiusUnits: 'pixels',
|
||
getRadius: 5,
|
||
getFillColor: [230, 0, 0]
|
||
});
|
||
|
||
const deckgl = new DeckGL({
|
||
container: 'map',
|
||
mapStyle: 'https://basemaps.cartocdn.com/gl/dark-matter-gl-style/style.json',
|
||
initialViewState: {
|
||
latitude: 0,
|
||
longitude: 0,
|
||
zoom: 1
|
||
},
|
||
layers: [pointsLayer]
|
||
});
|
||
```
|
||
|
||
## Using with Mapbox
|
||
|
||
[Mapbox GL JS](https://github.com/mapbox/mapbox-gl-js) is a JavaScript library for interactive, customizable vector maps on the web. Mapbox GL JS v1.x was open source, and it was forked as MapLibre (see [above](#using-with-maplibre)), so using Martin with Mapbox is similar to MapLibre. Mapbox GL JS can accept [MVT vector tiles](https://github.com/mapbox/vector-tile-spec) generated by Martin, and applies [a style](https://docs.mapbox.com/mapbox-gl-js/style-spec/) to them to draw a map using Web GL.
|
||
|
||
You can add a layer to the map and specify martin TileJSON endpoint as a vector source URL. You should also specify a `source-layer` property. For [Table Sources](#table-sources) it is `{table_name}` by default.
|
||
|
||
```js
|
||
map.addLayer({
|
||
id: 'points',
|
||
type: 'circle',
|
||
source: {
|
||
type: 'vector',
|
||
url: 'http://localhost:3000/points'
|
||
},
|
||
'source-layer': 'points',
|
||
paint: {
|
||
'circle-color': 'red'
|
||
}
|
||
});
|
||
```
|
||
|
||
## Source List
|
||
|
||
A list of all available sources is available in a catalogue:
|
||
|
||
```shell
|
||
curl localhost:3000/catalog | jq
|
||
```
|
||
|
||
```yaml
|
||
[
|
||
{
|
||
"id": "function_zxy_query",
|
||
"name": "public.function_zxy_query"
|
||
},
|
||
{
|
||
"id": "points1",
|
||
"name": "public.points1.geom"
|
||
},
|
||
...
|
||
]
|
||
```
|
||
|
||
## Composite Sources
|
||
|
||
Composite Sources allows combining multiple sources into one. Composite Source consists of multiple sources separated by comma `{source1},...,{sourceN}`
|
||
|
||
Each source in a composite source can be accessed with its `{source_name}` as a `source-layer` property.
|
||
|
||
### Composite Source TileJSON
|
||
|
||
Composite Source [TileJSON](https://github.com/mapbox/tilejson-spec) endpoint is available at `/{source1},...,{sourceN}`.
|
||
|
||
For example, composite source combining `points` and `lines` sources will be available at `/points,lines`
|
||
|
||
```shell
|
||
curl localhost:3000/points,lines | jq
|
||
```
|
||
|
||
### Composite Source Tiles
|
||
|
||
Composite Source tiles endpoint is available at `/{source1},...,{sourceN}/{z}/{x}/{y}`
|
||
|
||
For example, composite source combining `points` and `lines` sources will be available at `/points,lines/{z}/{x}/{y}`
|
||
|
||
```shell
|
||
curl localhost:3000/points,lines/0/0/0
|
||
```
|
||
|
||
## Table Sources
|
||
|
||
Table Source is a database table which can be used to query [vector tiles](https://github.com/mapbox/vector-tile-spec). When started, martin will go through all spatial tables in the database and build a list of table sources. A table should have at least one geometry column with non-zero SRID. All other table columns will be represented as properties of a vector tile feature.
|
||
|
||
### Table Source TileJSON
|
||
|
||
Table Source [TileJSON](https://github.com/mapbox/tilejson-spec) endpoint is available at `/{table_name}`.
|
||
|
||
For example, `points` table will be available at `/points`, unless there is another source with the same name, or if the table has multiple geometry columns, in which case it will be available at `/points.1`, `/points.2`, etc.
|
||
|
||
```shell
|
||
curl localhost:3000/points | jq
|
||
```
|
||
|
||
### Table Source Tiles
|
||
|
||
Table Source tiles endpoint is available at `/{table_name}/{z}/{x}/{y}`
|
||
|
||
For example, `points` table will be available at `/points/{z}/{x}/{y}`
|
||
|
||
```shell
|
||
curl localhost:3000/points/0/0/0
|
||
```
|
||
|
||
In case if you have multiple geometry columns in that table and want to access a particular geometry column in vector tile, you should also specify the geometry column in the table source name
|
||
|
||
```shell
|
||
curl localhost:3000/points.geom/0/0/0
|
||
```
|
||
|
||
## Function Sources
|
||
|
||
Function Source is a database function which can be used to query [vector tiles](https://github.com/mapbox/vector-tile-spec). When started, martin will look for the functions with a suitable signature. A function that takes `z integer` (or `zoom integer`), `x integer`, `y integer`, and an optional `query json` and returns `bytea`, can be used as a Function Source. Alternatively the function could return a record with a single `bytea` field, or a record with two fields of types `bytea` and `text`, where the `text` field is an etag key (i.e. md5 hash).
|
||
|
||
| Argument | Type | Description |
|
||
|----------------------------|---------|-------------------------|
|
||
| z (or zoom) | integer | Tile zoom parameter |
|
||
| x | integer | Tile x parameter |
|
||
| y | integer | Tile y parameter |
|
||
| query (optional, any name) | json | Query string parameters |
|
||
|
||
For example, if you have a table `table_source` in WGS84 (`4326` SRID), then you can use this function as a Function Source:
|
||
|
||
```sql, ignore
|
||
CREATE OR REPLACE FUNCTION function_zxy_query(z integer, x integer, y integer) RETURNS bytea AS $$
|
||
DECLARE
|
||
mvt bytea;
|
||
BEGIN
|
||
SELECT INTO mvt ST_AsMVT(tile, 'function_zxy_query', 4096, 'geom') FROM (
|
||
SELECT
|
||
ST_AsMVTGeom(ST_Transform(ST_CurveToLine(geom), 3857), ST_TileEnvelope(z, x, y), 4096, 64, true) AS geom
|
||
FROM table_source
|
||
WHERE geom && ST_Transform(ST_TileEnvelope(z, x, y), 4326)
|
||
) as tile WHERE geom IS NOT NULL;
|
||
|
||
RETURN mvt;
|
||
END
|
||
$$ LANGUAGE plpgsql IMMUTABLE STRICT PARALLEL SAFE;
|
||
```
|
||
|
||
```sql, ignore
|
||
CREATE OR REPLACE FUNCTION function_zxy_query(z integer, x integer, y integer, query_params json) RETURNS bytea AS $$
|
||
DECLARE
|
||
mvt bytea;
|
||
BEGIN
|
||
SELECT INTO mvt ST_AsMVT(tile, 'function_zxy_query', 4096, 'geom') FROM (
|
||
SELECT
|
||
ST_AsMVTGeom(ST_Transform(ST_CurveToLine(geom), 3857), ST_TileEnvelope(z, x, y), 4096, 64, true) AS geom
|
||
FROM table_source
|
||
WHERE geom && ST_Transform(ST_TileEnvelope(z, x, y), 4326)
|
||
) as tile WHERE geom IS NOT NULL;
|
||
|
||
RETURN mvt;
|
||
END
|
||
$$ LANGUAGE plpgsql IMMUTABLE STRICT PARALLEL SAFE;
|
||
```
|
||
|
||
The `query_params` argument is a JSON representation of the tile request query params. For example, if user requested a tile with [urlencoded](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/encodeURIComponent) params:
|
||
|
||
```shell
|
||
curl \
|
||
--data-urlencode 'arrayParam=[1, 2, 3]' \
|
||
--data-urlencode 'numberParam=42' \
|
||
--data-urlencode 'stringParam=value' \
|
||
--data-urlencode 'booleanParam=true' \
|
||
--data-urlencode 'objectParam={"answer" : 42}' \
|
||
--get localhost:3000/function_zxy_query/0/0/0
|
||
```
|
||
|
||
then `query_params` will be parsed as:
|
||
|
||
```json
|
||
{
|
||
"arrayParam": [1, 2, 3],
|
||
"numberParam": 42,
|
||
"stringParam": "value",
|
||
"booleanParam": true,
|
||
"objectParam": { "answer": 42 }
|
||
}
|
||
```
|
||
|
||
You can access this params using [json operators](https://www.postgresql.org/docs/current/functions-json.html):
|
||
|
||
```sql, ignore
|
||
...WHERE answer = (query_params->'objectParam'->>'answer')::int;
|
||
```
|
||
|
||
### Function Source TileJSON
|
||
|
||
Function Source [TileJSON](https://github.com/mapbox/tilejson-spec) endpoint is available at `/{function_name}`
|
||
|
||
For example, `points` function will be available at `/points`
|
||
|
||
```shell
|
||
curl localhost:3000/points | jq
|
||
```
|
||
|
||
### Function Source Tiles
|
||
|
||
Function Source tiles endpoint is available at `/{function_name}/{z}/{x}/{y}`
|
||
|
||
For example, `points` function will be available at `/points/{z}/{x}/{y}`
|
||
|
||
```shell
|
||
curl localhost:3000/points/0/0/0
|
||
```
|
||
|
||
## MBTile and PMTile Sources
|
||
|
||
Martin can serve any type of tiles from [PMTile](https://protomaps.com/blog/pmtiles-v3-whats-new) and [MBTile](https://github.com/mapbox/mbtiles-spec) files. To serve a file from CLI, simply put the path to the file or the directory with `*.mbtiles` or `*.pmtiles` files. For example:
|
||
|
||
```shell
|
||
martin /path/to/mbtiles/file.mbtiles /path/to/directory
|
||
```
|
||
|
||
You may also want to generate a [config file](#configuration-file) using the `--save-config my-config.yaml`, and later edit it and use it with `--config my-config.yaml` option.
|
||
|
||
|
||
## Command-line Interface
|
||
|
||
You can configure martin using command-line interface. See `martin --help` or `cargo run -- --help` for more information.
|
||
|
||
```shell
|
||
Usage: martin [OPTIONS] [CONNECTION]
|
||
|
||

|
||
-d, --default-srid <DEFAULT_SRID>
|
||
If a spatial table has SRID 0, then this default SRID will be used as a fallback
|
||
-p, --pool-size <POOL_SIZE>
|
||
Maximum connections pool size [DEFAULT: 20]
|
||
-h, --help
|
||

|
||
Print version information
|
||
```
|
||
|
||
## Environment Variables
|
||
|
||
You can also configure martin using environment variables, but only if the configuration file is not used. See [configuration section](#configuration-file) on how to use environment variables with config files.
|
||
|
||
| Environment variable | Example | Description |
|
||
|-------------------------------|--------------------------------------|---------------------------------------------|
|
||
| `DATABASE_URL` | `postgresql://postgres@localhost/db` | Postgres database connection |
|
||
| `CA_ROOT_FILE` | `./ca-certificate.crt` | Loads trusted root certificates from a file |
|
||
| `DEFAULT_SRID` | `4326` | Fallback SRID |
|
||
| `DANGER_ACCEPT_INVALID_CERTS` | `0` | Trust invalid certificates (any value) |
|
||
|
||
## Configuration File
|
||
|
||
If you don't want to expose all of your tables and functions, you can list your sources in a configuration file. To start martin with a configuration file you need to pass a path to a file with a `--config` argument. Config files may contain environment variables, which will be expanded before parsing. For example, to use `MY_DATABASE_URL` in your config file: `connection_string: ${MY_DATABASE_URL}`, or with a default `connection_string: ${MY_DATABASE_URL:-postgresql://postgres@localhost/db}`
|
||
|
||
```shell
|
||
martin --config config.yaml
|
||
```
|
||
|
||
You may wish to auto-generate a config file with `--save-config` argument. This will generate a config yaml file with all of your configuration, which you can edit to remove any sources you don't want to expose.
|
||
|
||
```yaml
|
||
# Connection keep alive timeout [default: 75]
|
||
keep_alive: 75
|
||
|
||

```
|
||
|
||
## Using with Docker
|
||
|
||
You can use official Docker image [`maplibre/martin`](https://hub.docker.com/r/maplibre/martin)
|
||
|
||
```shell
|
||
docker run \
|
||
-p 3000:3000 \
|
||
-e DATABASE_URL=postgresql://postgres@localhost/db \
|
||
maplibre/martin
|
||
```
|
||
|
||
If you are running PostgreSQL instance on `localhost`, you have to change network settings to allow the Docker container to access the `localhost` network.
|
||
|
||
For Linux, add the `--net=host` flag to access the `localhost` PostgreSQL service.
|
||
|
||
```shell
|
||
docker run \
|
||
--net=host \
|
||
-p 3000:3000 \
|
||
-e DATABASE_URL=postgresql://postgres@localhost/db \
|
||
maplibre/martin
|
||
```
|
||
|
||
For macOS, use `host.docker.internal` as hostname to access the `localhost` PostgreSQL service.
|
||
|
||
```shell
|
||
docker run \
|
||
-p 3000:3000 \
|
||
-e DATABASE_URL=postgresql://postgres@host.docker.internal/db \
|
||
maplibre/martin
|
||
```
|
||
|
||
For Windows, use `docker.for.win.localhost` as hostname to access the `localhost` PostgreSQL service.
|
||
|
||
```shell
|
||
docker run \
|
||
-p 3000:3000 \
|
||
-e DATABASE_URL=postgresql://postgres@docker.for.win.localhost/db \
|
||
maplibre/martin
|
||
```
|
||
|
||
## Using with Docker Compose
|
||
|
||
You can use example [`docker-compose.yml`](https://raw.githubusercontent.com/maplibre/martin/main/docker-compose.yml) file as a reference
|
||
|
||
```yml
|
||
version: '3'
|
||
|
||
services:
|
||
martin:
|
||
image: maplibre/martin:v0.6.2
|
||
restart: unless-stopped
|
||
ports:
|
||
- "3000:3000"
|
||
environment:
|
||
- DATABASE_URL=postgresql://postgres:password@db/db
|
||
depends_on:
|
||
- db
|
||
|
||
db:
|
||
image: postgis/postgis:14-3.3-alpine
|
||
restart: unless-stopped
|
||
environment:
|
||
- POSTGRES_DB=db
|
||
- POSTGRES_USER=postgres
|
||
- POSTGRES_PASSWORD=password
|
||
volumes:
|
||
- ./pg_data:/var/lib/postgresql/data
|
||
```
|
||
|
||
First, you need to start `db` service
|
||
|
||
```shell
|
||
docker-compose up -d db
|
||
```
|
||
|
||
Then, after `db` service is ready to accept connections, you can start `martin`
|
||
|
||
```shell
|
||
docker-compose up -d martin
|
||
```
|
||
|
||
By default, martin will be available at [localhost:3000](http://localhost:3000/)
|
||
|
||
## Using with Nginx
|
||
|
||
You can run martin behind Nginx proxy, so you can cache frequently accessed tiles and reduce unnecessary pressure on the database.
|
||
|
||
```yml
|
||
version: '3'
|
||
|
||
services:
|
||
nginx:
|
||
image: nginx:alpine
|
||
restart: unless-stopped
|
||
ports:
|
||
- "80:80"
|
||
volumes:
|
||
- ./cache:/var/cache/nginx
|
||
- ./nginx.conf:/etc/nginx/nginx.conf:ro
|
||
depends_on:
|
||
- martin
|
||
|
||
martin:
|
||
image: maplibre/martin:v0.6.2
|
||
restart: unless-stopped
|
||
environment:
|
||
- DATABASE_URL=postgresql://postgres:password@db/db
|
||
depends_on:
|
||
- db
|
||
|
||
db:
|
||
image: postgis/postgis:14-3.3-alpine
|
||
restart: unless-stopped
|
||
environment:
|
||
- POSTGRES_DB=db
|
||
- POSTGRES_USER=postgres
|
||
- POSTGRES_PASSWORD=password
|
||
volumes:
|
||
- ./pg_data:/var/lib/postgresql/data
|
||
```
|
||
|
||
You can find an example Nginx configuration file [here](https://github.com/maplibre/martin/blob/main/nginx.conf).
|
||
|
||
### Rewriting URLs
|
||
|
||
If you are running martin behind Nginx proxy, you may want to rewrite the request URL to properly handle tile URLs in [TileJSON](#table-source-tilejson) [endpoints](#function-source-tilejson).
|
||
|
||
```nginx
|
||
location ~ /tiles/(?<fwd_path>.*) {
|
||
proxy_set_header X-Rewrite-URL $uri;
|
||
proxy_set_header X-Forwarded-Host $host:$server_port;
|
||
proxy_set_header X-Forwarded-Proto $scheme;
|
||
proxy_redirect off;
|
||
|
||
proxy_pass http://martin:3000/$fwd_path$is_args$args;
|
||
}
|
||
```
|
||
|
||
### Caching tiles
|
||
|
||
You can also use Nginx to cache tiles. In the example, the maximum cache size is set to 10GB, and caching time is set to 1 hour for responses with codes 200, 204, and 302 and 1 minute for responses with code 404.
|
||
|
||
```nginx
|
||
http {
|
||
...
|
||
proxy_cache_path /var/cache/nginx/
|
||
levels=1:2
|
||
max_size=10g
|
||
use_temp_path=off
|
||
keys_zone=tiles_cache:10m;
|
||
|
||
server {
|
||
...
|
||
location ~ /tiles/(?<fwd_path>.*) {
|
||
proxy_set_header X-Rewrite-URL $uri;
|
||
proxy_set_header X-Forwarded-Host $host:$server_port;
|
||
proxy_set_header X-Forwarded-Proto $scheme;
|
||
proxy_redirect off;
|
||
|
||
proxy_cache tiles_cache;
|
||
proxy_cache_lock on;
|
||
proxy_cache_revalidate on;
|
||
|
||
# Set caching time for responses
|
||
proxy_cache_valid 200 204 302 1h;
|
||
proxy_cache_valid 404 1m;
|
||
|
||
proxy_cache_use_stale error timeout http_500 http_502 http_503 http_504;
|
||
add_header X-Cache-Status $upstream_cache_status;
|
||
|
||
proxy_pass http://martin:3000/$fwd_path$is_args$args;
|
||
}
|
||
}
|
||
}
|
||
```
|
||
|
||
You can find an example Nginx configuration file [here](https://github.com/maplibre/martin/blob/main/nginx.conf).
|
||
|
||
## Building from Source
|
||
|
||
You can clone the repository and build martin using [cargo](https://doc.rust-lang.org/cargo) package manager.
|
||
|
||
```shell
|
||
git clone git@github.com:maplibre/martin.git
|
||
cd martin
|
||
cargo build --release
|
||
```
|
||
|
||
The binary will be available at `./target/release/martin`.
|
||
|
||
```shell
|
||
cd ./target/release/
|
||
./martin postgresql://postgres@localhost/db
|
||
```
|
||
|
||
## Debugging
|
||
|
||
Log levels are controlled on a per-module basis, and by default all logging is disabled except for errors. Logging is controlled via the `RUST_LOG` environment variable. The value of this environment variable is a comma-separated list of logging directives.
|
||
|
||
This will enable debug logging for all modules:
|
||
|
||
```shell
|
||
export RUST_LOG=debug
|
||
martin postgresql://postgres@localhost/db
|
||
```
|
||
|
||
While this will only enable verbose logging for the `actix_web` module and enable debug logging for the `martin` and `tokio_postgres` modules:
|
||
|
||
```shell
|
||
export RUST_LOG=actix_web=info,martin=debug,tokio_postgres=debug
|
||
martin postgresql://postgres@localhost/db
|
||
```
|
||
|
||

||
## Recipes
|
||
|
||
|
||
### Using with DigitalOcean PostgreSQL
|
||
|
||
You can use martin with [Managed PostgreSQL from DigitalOcean](https://www.digitalocean.com/products/managed-databases-postgresql/) with PostGIS extension
|
||
|
||
First, you need to download the CA certificate and get your cluster connection string from the [dashboard](https://cloud.digitalocean.com/databases). After that, you can use the connection string and the CA certificate to connect to the database
|
||
|
||
```shell
|
||
martin --ca-root-file ./ca-certificate.crt postgresql://user:password@host:port/db?sslmode=require
|
||
```
|
||
|
||
### Using with Heroku PostgreSQL
|
||
|
||
You can use martin with [Managed PostgreSQL from Heroku](https://www.heroku.com/postgres) with PostGIS extension
|
||
|
||
```shell
|
||
heroku pg:psql -a APP_NAME -c 'create extension postgis'
|
||
```
|
||
|
||
In order to trust the Heroku certificate, you can disable certificate validation with either `DANGER_ACCEPT_INVALID_CERTS` environment variable
|
||
|
||
```shell
|
||
DATABASE_URL=$(heroku config:get DATABASE_URL -a APP_NAME) DANGER_ACCEPT_INVALID_CERTS=true martin
|
||
```
|
||
|
||
or `--danger-accept-invalid-certs` command-line argument
|
||
|
||
```shell
|
||
martin --danger-accept-invalid-certs $(heroku config:get DATABASE_URL -a APP_NAME)
|
||
```
|
