Use ARondor Docker images instead of building ours

Context

We want to use Docker images provided by ARondor.

The available images are stored in their artifactory and has following names:

• arender-hmi
• arender-rendition-broker
• arender-jni-engine
• arender-pdfbox
• arender-converter
• arender-dfs

The images share the same versioning than ARender, so: 4.0.5.NX1.1, 4.0.5.NX2.0...

Tasks

Previewer

Previewer images will contain our version of ARender (suffixed by NX something). The image has as based tomcat:9.0-jre8-alpine. The receipt is:

• put our connector and its dependencies under /usr/local/tomcat/webapps/ROOT/WEB-INF/lib/
• put our default configuration file under /usr/local/tomcat/webapps/ROOT/WEB-INF/classes

We need to split the code/arender-previewer module in order to extract our connector and the war packaging stuff.

Rendition

Rendition images should be used directly without any customization from ours.
The customization we currently have for task conversion (see there) could be done on ARender side or with an environment variable set on arender-converter container.

Deployment

Goal is to have the helm chart for preview working in our Jenkins X. This will also describe how to deploy the whole stack with another technology.

Known things to change:

• provide a deployment for each rendition micro services
• adapt the readyness and liveness probe path
• use of ARENDER_ and ARENDERSRV_ for both arender.properties and arender-server.properties
