Setup application.yml with correct Camunda webservice URL and username/password.

And very important: change the topic identifiers for execute-topic, read-file-topic and write-file-topic.

Best practice is, to use the servers hostname as prefix of the topic – so in our case this is ansibletest-execute, ansibletest-write-file and ansibletest-readfile.
This topic is later used in BPMN Service Task definition as Topic.

Add /usr/bin/ansible and /usr/bin/ansible-playbook to execute-white-list.

If you want to write and read files e.g. config files for ansible, add /etc/ansible to read-file-white-list and write-file-white-list.

while [ -h „$SOURCE“ ]; do # resolve $SOURCE until the file is no longer a symlink

DIR=$( cd -P „$( dirname „$SOURCE“ )“ >/dev/null 2>&1 && pwd )

SOURCE=$(readlink „$SOURCE“)

[[ $SOURCE != /* ]] && SOURCE=$DIR/$SOURCE # if $SOURCE was a relative symlink, we need to resolve it relative to the path where the symlink file was located

Start it e.g. from rc.local after system boots (rc.local has to be enabled in ubuntu 20.04 and newer – e.g. have a look at https://marsown.com/wordpress/how-to-enable-etc-rc-local-with-systemd-on-ubuntu-20-04/).
