Script Instances lost after reboot of ctrlX CORE

Hello everyone,

once I have created an script instances (like shown in this example here: /ctrlx-core-25gnfzl4/post/how-to-run-python-scripts-on-the-ctrlx-core-Y4EdXQVWBXO9oEn) it is not existing anymore when i reboot my ctrlX CORE (virtual). Should it be like this? Is there a possibility to save the created script instances permanetly?

Thanks!

Hi,

you can use the "init script" functionallity.

Download and unzip the configuration via the web interface
Write a python script 'init.py' with content eg. 'print("Hello ctrlX")' and save it in the configuration in the directory "script" (any other dir/filename would also work)
Zip the configuration directory (now includes the init.py file) and upload it to the core via web ui
Write on the datalyer node "script/cfg/init-script" the payload "{"file": "activeConfiguration/script/init.py","language": "python","parameter": []}" (can be done also via web ui)
Reboot
Now there is always a python instance called "Base" (prerequisite is the python runtime snap)
POST the following payload on "script/instances/Base/cmd/file" to excecute any script you need (via web ui or REST API). Payload eg. '{"name":"activeConfiguration/script/myworker.py","param":[]}'

Notes:

It seems in the docu linked above is a mistake according to the path for the init script see: activeConfiguration vs. activeSolution
