does pulumi yaml have a for_each / count (terraform) equivalent?

[foxydevloper]

Moving my infrastructure to use pulumi instead of terraform, not a fan of any of the provided languages, so I'm using pulumi yaml. Is there any equivalent to terraform's for_each / count in the pulumi yaml? I'm trying to deploy a server in multiple regions. The second best thing I've found is to make a stack for each region, although I'd want to be able to deploy to every region with a single command

@foxydevloper thanks for asking. No, Pulumi YAML does not have any for loop or conditional logic. You have a few options, including your workaround.

You could use a tool to generate YAML, such as cue, jsonnet, or even a shell script. The compiler option allows you to specify an external command to generate the program:

You could also convert the YAML program to another language and use the looping functionality in it, via pulumi convert:

Thank you! I've used jsonnet before, so I'll go with that.

Glad you have a path forward.
