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.
{: .note}
Open your terminal and run the following command:
docker pull opensearchproject/opensearch-maps-server:1.0.0
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.
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). {: .note}
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
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.
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/
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.
Configure the manifest URL in opensearch_dashboards.yml
:
map.opensearchManifestServiceUrl: "http://localhost:8080/manifest.json"
- On the OpenSearch Dashboards console, select Dashboards 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.
