While using for_each in modules, I noticed that it doesn’t behave as I would expect from an ordinary loop. Each iteration run in parallel, that is, while iteration 0 is execution iteration 1 starts. Is this intended? If so, is it possible to execute sequentially?

There’s the parallelism flag for apply, which applies to the entire operation. You might have luck using depends_on or a normal variable to route output from one instance to another. Something along the lines of: locals { set = toset(["1", "2"]) } module mod { for_each = local.set sequenceco…

Hi, thank you for coming back. Had tried the suggestion of indexed based outputs for modules iteration but it creates cyclic dependencies and terraform doesn’t like that. Unfortunately it is related to for_each not supporting inline provider definition. In this case, it is to use kubectl/helm, had…
