Using the self-host maps server

Using the self-host maps server

The self-host maps server for OpenSearch Dashboards allows users to access the default maps service in air-gapped environments. OpenSearch-compatible map URLs include a map manifest with map tiles and vectors, the map tiles, and the map vectors.

The following sections provide steps for setting up and using the self-host maps server with OpenSearch Dashboards.

You can access the maps-server image via the official OpenSearch Docker Hub repository.

Pulling the Docker image

Open your terminal and run the following command:

docker pull opensearchproject/opensearch-maps-server:1.0.0

Setting up the server

You must set up the map tiles before running the server. You have two setup options: Use the OpenSearch-provided maps service tiles set, or generate the raster tiles set.

Option 1: Use the OpenSearch-provided maps service tiles set

Create a Docker volume to hold the tiles set:

docker volume create tiles-data

Download the tiles set from the OpenSearch maps service. Two planet tiles sets are available based on the desired zoom level:

Zoom Level 8 (https://maps.opensearch.org/offline/planet-osm-default-z0-z8.tar.gz)
Zoom level 10 (https://maps.opensearch.org/offline/planet-osm-default-z0-z10.tar.gz)

The planet tiles set for zoom level 10 (2 GB compressed/6.8 GB uncompressed) is approximately 10 times larger than the set for zoom level 8 (225 MB compressed/519 MB uncompressed).

docker run \
    -e DOWNLOAD_TILES=https://maps.opensearch.org/offline/planet-osm-default-z0-z8.tar.gz \
    -v tiles-data:/usr/src/app/public/tiles/data/ \
    opensearch/opensearch-maps-server \
    import

Option 2: Generate the raster tiles set

To generate the raster tiles set, use the raster tile generation pipeline and then use the tiles set absolute path to create a volume to start the server.

Starting the server

Use the following command to start the server using the Docker volume tiles-data. The following command is an example using host URL “localhost” and port “8080”:

docker run \
    -v tiles-data:/usr/src/app/public/tiles/data/ \
    -e HOST_URL='http://localhost' \
    -p 8080:8080 \
    opensearch/opensearch-maps-server \
    run

Or, if you generated the raster tiles set, run the server using that tiles set:

docker run \
    -v /absolute/path/to/tiles/:/usr/src/app/dist/public/tiles/data/ \
    -p 8080:8080 \
    opensearch/opensearch-maps-server \
    run

To access the tiles set, open the URLs in a browser on the host or use the curl command curl http://localhost:8080/manifest.json.

Confirm the server is running by opening each of the following links in a browser on your host or with a curl command (for example, curl http://localhost:8080/manifest.json).

Map manifest URL: http://localhost:8080/manifest.json
Map tiles URL: http://localhost:8080/tiles/data/{z}/{x}/{y}.png
Map tiles demo URL: http://localhost:8080/

Using the self-host maps server with OpenSearch Dashboards

You can use the self-host maps server with OpenSearch Dashboards by either adding the parameter to opensearch_dashboards.yml or configuring the default WMS properties in OpenSearch Dashboards.

Option 1: Configure opensearch_dashboards.yml

Configure the manifest URL in opensearch_dashboards.yml:

map.opensearchManifestServiceUrl: "http://localhost:8080/manifest.json"

Option 2: Configure Default WMS properties in OpenSearch Dashboards

On the OpenSearch Dashboards console, select Stack Management > Advanced Settings.
Locate visualization:tileMap:WMSdefaults under Default WMS properties.
Change "enabled": false to "enabled": true and add the URL for the valid map server.
