Inherit environment variables from the worker

[naorlivne]

I can see some cases that inheriting envvars from the worker-manager host node will be a good idea, that would allow devices to have some customizability that might be useful for distributed systems yet still managed centrally (same IoT sensor everywhere, but a tag is manually set on each sensor with it's location name, etc...), thinking it could be any combination of the follow:

• envvar with some sort of prefix (IE NEBULA_)
• file with a list of the envvars

not sure about how to handle multiple apps each getting different envvars yet, anyone got any ideas in that regards?

A really simple soultion that was staring me in the face & I somehow missed is to use parse_it and to have it have a dict of all worker inherited key:values in the following format:

{
   "nebula_worker_envvars": {
        "app": {
             "app_1": {key_1":" value_1", .... "key_n":"value_n"},
            ...
            "app_n": {key_1":" value_1", .... "key_n":"value_n"}
             },
         "cron": {
             "cron_1": {key_1":" value_1", .... "key_n":"value_n"},
            ...
            "cron_n": {key_1":" value_1", .... "key_n":"value_n"}
             },
       }
}
