What is the template: config: used for inside the pulumi.yaml file? I added a few values in there, that are not part of the config, but still complaining that they dont exist. I want to use the default value unless given one

The configs are set as part of the stack config (so

Pulumi.{stackname}.yaml

) - the config in the main

Pulumi.yaml

file are for defaults. You can set config by running

pulumi config set {key} {value}

which will write them to the stack config file

“the config in the main 

Pulumi.yaml

 file are for defaults.” but those defaults are never used? how do i use the defaults? do i need to enter a empty config in Pulumi.{stackname}.yaml ?

If you do

pulumi config set {key} {value}

then Pulumi will automatically create the stack config file
