LSST TAP Service

This repository contains the LSST TAP service. It is based on the CADC TAP service code and uses this as a dependency, and then adds special logic to work with QServ.

Build

Run ./build.sh

Deployment

Docker

After the Build step above, a set of containers with the dev tag will exist on your local machine. Then when you run:

docker-compose up -d && ./waitForContainersReady.sh && ./checkAvailability.sh

This should start a local group of containers, wait for them to be ready, and then check that the availability endpoint returns a 200 and a simple sync query works. This validates that your local TAP implementation is working. You can now either use curl, TOPCAT, pyvo, or any other local TAP client pointed at http://localhost:8080/tap to test out your TAP service.

Here is an example of using curl to query the TAP service:

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

Pushing to hub.docker.com

After building a set of images (with the dev tag), and testing them out, you can run the ./push.sh script providing a docker tag to push to. For example

./push.sh new_feature_test

will create a set of containers with the tag new_feature_test. These can then be used in a k8s environment with the Helm chart located here:
