Motivation

We're helping our customers to automate their processes since 2005. Most of the time we've done this with properitary tools and had to fight with outdated tools. We've spend a lot of time doing tasks that could be done with todays technology much faster and more efficiently. The goal of our Open Source Automation project is to create a state of the art automation solution for BMC Remedy ITSM based on open source technology so everyone can leverage it. We decided to give Node-RED a try.

Why Node-RED

Node-RED is an open source low-code programming tool which UI is completly brower based. It is famous in the IoT/ Edge community and therefore very scalable. It has a braod user community, regular releases and more than 4.000 plugins/ extensions are available for nearly every use case.

What is the core of ths project

We've created Node-RED plugins that allow you to create, query, update and delete records in Remedy. So all basic CRUD operations are already available. As our next step we want to create a flexible set of workflows that are based on our best practices and will help you to get your automations rolling a lot faster.

Getting started

First deploy Node-RED & RAPI (our API Gateway) as docker containers. Use the following compose file as a start:


version: '3.4'  services:   api:      image: nodered/node-red     restart: always     volumes:       - data:/data     networks:       - traefik-net       - default          rapi:      image: manyos/rapi     environment:        - GRAILS_OPTS=-XX:MaxPermSize=1024m -Xmx4096M -server     restart: always     networks:       - default        networks:   traefik-net:     external: true      volumes:   data:     driver: local     driver_opts:       type: nfs       o: nfsvers=4,addr=dockershare,rw       device: ":/mnt/main/replicated/dockerShares/red-sandbox"

Do not forget to secure your installation.

Now open Settings -> Manage Palette and install @manyos/node-red-contrib-rapi

You will now have four new nodes available.

The first time you want to use one of the RAPI nodes you have to setup a server connection:

Once done you are ready to go:

A very simple testflow could look like this:

Your are now able to create your automations! In part two of this project we're are going to setup an automation framework that enables you to create new automations in minutes.
