- We would like to execute some scripts at worker/controller bootstrapping.

the cluster-init operation is performed the file CJE_INSTALLATION/share/setup-templates/core/scripts/cloud-config.yaml is copied to your project to init your cluster, so you will have to edit the ./share/setup-templates/core/scripts/cloud-config.yaml with your modifications before execute the cluster-init operation, then run the cluster-init, after that you could manage other modifications that you want to make on it on .dna/scripts/cloud-config.yaml. That file is the template used to create all project and could change with the version of CJE.
You have a file inside the project folder .dna/scripts/cloud-config.yaml, you can edit it to add new commands to your workers/controllers bootstrapping.
you could add some commands to the runcmd section.
