LabCAS Test Workflow

Description

The "LabCAS Test Workflow" is a demo application that illustrates how to execute a mock workflow using LabCAS services deployed as separate Docker containers. The test workflow is composed of a single task, which generates and publishes a small file.

Execution

• Clone this repository, cd to this example directory:
  • git clone https://github.com/oodt-cloud/docker.git
  • cd labcas/labcas-test
• In a first docker terminal, start the LabCAS services in separate containers: the OODT File manager (with Solr back-end), the OODT Workflow Manager, and the OODT Product Server. Follow the services standard output.
  • docker-compose up -d
  • docker ps
  • docker-compose logs -f
• In a second docker terminal, connect to the Workflow Manager container and submit a test workflow:
  • docker exec -it oodt_wmgr /bin/bash
  • cd $OODT_HOME/cas-workflow/bin
  • ./wmgr-client --url http://localhost:9001 --operation --sendEvent --eventName labcas-test --metaData --key experiment 1 --key species snakes --key location LAB01
• Follow the test-workflow output in the first docker terminal
• Still in the second terminal, verify that the output file has been published to the Solr catalog, and that it is downloadable from the OODT Product Server:
  • wget 'http://oodt.filemgr.host:8983/solr/oodt-fm/select?q=*%3A*&wt=json&indent=true'
  • wget 'http://oodt.fmprod.host:8080/fmprod/data?productID=LabcasTestFile.labcas-test-output.txt'
• In the first Docker window, shut down the LabCAS services and remove the Docker containers (the session in the second Docker terminal will be disconnected as well):
  • ctrl-C
  • docker-compose down
