GeoDocker is a collection of Docker images encapsulating a distributed geo-processing platform based on GeoTrellis, GeoMesa, and GeoWave. The emphasis is on providing integration between these projects and exposing geo-processing functionality in Hadoop ecosystem.
This project is in active development. The layout and composition of GeoDocker may change as we explore this our use-case further. Despite that we're committed to maintaining sanity by providing publicly published, versioned, and tested images. Your feedback and contributions are always welcome.
- Integrate GeoTrellis, GeoWave, and GeoMesa as a unified platform
- Provide realistic and convenient distributed integration testing environment
- Support deployment of GeoDocker to Amazon EMR
- Explore and support other deployment options like DC/OS and ECS
It is not necessary to build and publish these containers to use them as-is. Pre-built images are available on quay.io. Building is only necessary in-order to customize and develop GeoDocker.
All images contain a Makefile which provide following targets:
build: Builds the container withlatesttagtest: Runs the container testspublish: Publishes the container withlatesttag and tag provided by a$TAGenvironment variable (ex:make publish TAG=ABC123)
These targets are also used by Travis Ci as specified in .travis.yml
Those images which contain multiple container roles or depend on instance of other containers to function also provide a docker-compose.yml file which allows to easily bring up an local cluster. This cluster can be used for exploration, integration testing, and debugging.
