gCube Orchestrator

gCube Orchestrator is a Conductor based implementation of an orchestrator of administrative tasks.

It is based on a self-contained Docker image avilable on dockerhub that incorporates bith the Conductor server and UI. The image currently uses an in-memory persistence and does not rely on any replication for performance or fault-tolerance. Two Python based workers for executing REST calls and Python code have been added to support the needed functionality. They are pulled from dockerhub and initialized through the common docker-compose file together with their corresponding Task definitions.

In addition, the initialization phase also uploads a set of workflows that handle events coming from:

  • the gCube Liferay based gateways
  • the IAM service based on Keycloak

Please refer to proper documentation for more information.

Structure of the project

The docker-compose file pulls two public images from the nubisware account on Docker hub which setup the conductor server and UI and the Python based workers. A third image for initializing the orchestrator is created on the fly from the Dockerfile.

Built With


The command to pull a complete instance of the gCube Orchestrator is

docker-compose up -d

The command to tear down an instance of the gCube Orchestrator is

docker-compose down
