Conductor Setup

Conductor Setup is composed of a set of ansible roles and a playbook named site-*.yaml useful for deploying a docker swarm running Conductor microservice orchestrator by Netflix OSS.

Current setup is based on Conductor 3.0.4 version adapted by Nubisware S.r.l. It uses the docker images on dockerhub:

  • nubisware/conductor-server:3.0.4
  • nubisware/conductor-ui-oauth2:3.0.4 (which has been improved with Oauth2 login in collaboration with Keycloak)

Besides the basic components Conductor itself (server and ui) and Elasticsearch 6.1.8, the repository can be configured to launch postgres or mysql persistence plus basic python based workers for running PyRest, PyMail, PyExec and PyShell in the same Swarm. In addition a nginx based PEP can be executed to protect the conductor REST API server. It is also possible to connect to an external postgres for stateful deployments.

Structure of the project

The folder roles contains the necessary roles for configuring the different configurations There are 4 file for deploying to local, nw-cluster or D4SCience dev, pre and prod environments.

To run a deployment

ansible-playbook site-X.yaml

whereas

ansible-playbook site-X.yaml -e dry=true

only generates the files for the stack without actually deploying it.

The folder local-site contains a ready version for quickly launching a conductor instance with no replications (except workers), no auth in the Conductor UI and no PEP.

docker stack deploy -c elasticsearch-swarm.yaml -c postgres-swarm.yaml -c conductor-swarm.yaml -c conductor-workers-swarm.yaml -c pep-swarm.yaml conductor

When you have ensured that Postgres and Elasticsearch are running, execute:

docker stack deploy -c conductor-swarm.yaml conductor

This will create a local stack accessible through permissive pep at port 80. Please add two mappings for localhost in your /etc/hosts

127.0.1.1 conductor-server conductor-ui
