build.sh

#!/bin/sh
docker build -t baye/oic:1 .

runDevOIC.sh (Mount NFS on docker host first, then bind mount the docker host NFS to container using -v because some of the integration uses FTP connector)

#!/bin/sh
docker run -dit --restart always -v /usr/local/WindozeShared/:/usr/local/WindozeShared -v /scratch/transfer/Concur/DEV/:/scratch/transfer/Concur/DEV/ --name devOIC baye/oic:2

connect.sh (I’m lazy to type the whole thing every time I want to connect to a docker container)

#!/bin/sh
docker exec -it devOIC /bin/bash

Dockerfile
Not required to run connectivity.jar with nohup because docker container will be running the java process as the main process in detach mode)
Ensure current OIC_URL, OIC_USER and OIC_PASSWORD environment are set in Dockerfile, we will unset them later.
