LSST TAP Demo service

Build

Run ./build.sh

Deployment

Docker

This is a working prototype using a TAP implementation with an Oracle 11 g database.

After the Build step above, we can create a Docker deployment like so:

  • cp build/libs/*.war docker/
  • cd docker/
  • docker-compose up -d && ./waitForContainersReady.sh

The necessary Docker images will be downloaded, including the large Oracle one, then the service will be available on port 8080. You can then issue a request like:

http://localhost:8080/tap/availability

Which will provide you with an XML document as to the health of the service. If it reads with the message:

The TAP ObsCore service is accepting queries

Then the TAP service is running properly. You can then issue a query to the sample ObsCore table:

curl -L -d 'QUERY=SELECT+TOP+1+*+FROM+TAP_SCHEMA.obscore&LANG=ADQL' http://localhost:8080/tap/sync

Dedicated web server

If you have a dedicated Servlet Container (i.e. Tomcat) running already, run the Build step above, then copy the WAR artifact from build/libs/ to your Servlet Container's webapp deployment directory.
