GeoServer Config

Configuration for geoserver and additional resources needed to host stuff there.

Docker in EC2

EC2 Setup

Launch an instance using this user data. It is recommended the instance to have >=8Gb RAM and >=30Gb ephemeral storage. A good alternative is the t3.large which costs ~60 USD/month as of 02/10/2023.

Connect to your instance and add docker to user group by running:

sudo usermod -aG docker $USER
newgrp docker # restarts docker

Launch Geoserver

Pull the geoserver image:

docker pull docker.osgeo.org/geoserver:2.23.x 

Now run the container, installing COG extension and using a local data directory at /MY/DATADIRECTORY. As detailed in the documentation: this setup allows direct management of the file data shared with the container. This setup is also easy to update to use the latest container.

docker run --mount type=bind,src=/MY/DATADIRECTORY,target=/opt/geoserver_data -it -p8080:8080 --env INSTALL_EXTENSIONS=true --env COMMUNITY_EXTENSIONS="cog" --env JAVA_TOOL_OPTIONS="-Xmx4096m" docker.osgeo.org/geoserver:2.23.x

The JAVA_TOOL_OPTIONS is important to increase the maximum hava heap size available for the app. The example command provided earlier sets this limit on ~4Gb For coverage stores, a large heap size is necessary since there is a lot of data to bring. You can adjust it according to your use case. Run java -XX:+PrintFlagsFinal -version | grep MaxHeapSize for getting the max heat space in the docker container.

Optimization of Geoserver ImageMosaic

• See geoserver documentation

Example Notebooks

• Coverage Store using Cog Images: setup a WMS/WMTS-T service using COG rasters located in cloud storage

TODO

• Fix creating new datastore with existing database index: geoserver repo issue
