Iterate over list of list of maps in terraform

Question

Consider I have a variable that is a list of list of maps.

Example:

    processes = [
      [
       {start_cmd: \"a-server-start\", attribute2:\"ty         


        

Answer 1

Using terraform 0.12.x

locals {
  processes = [
    [
      { start_cmd: "a-server-start", type: "type_a", name: "inglorious bastards" },
      { start_cmd: "a-worker-start", type: "type_b", name: "kill bill" },
      { start_cmd: "a--different-worker-start", type: "type_c", name: "pulp fiction" },
    ],
    [
      { start_cmd: "b-server-start", type: "type_a", name: "inglorious bastards" },
      { start_cmd: "b-worker-start", type: "type_b", name: "kill bill" },
    ]
  ]
}

# just an example
data "archive_file" "applications" {
  count = length(local.processes)

  type = "zip"

  output_path = "applications.zip"

  dynamic "source" {
    for_each = local.processes[count.index]

    content {
      content  = source.value.type
      filename = source.value.name
    }
  }
}

$ terraform apply
data.archive_file.applications[0]: Refreshing state...
data.archive_file.applications[1]: Refreshing state...

Apply complete! Resources: 0 added, 0 changed, 0 destroyed.

If a create_application resource existed, it can be modeled like so

resource "create_application" "applications" {
  count             = length(local.processes)
  name              = ""
  migration_command = "" 

  dynamic "proc" {
    for_each = local.processes[count.index]

    content {
      name         = proc.value.name
      init_command = proc.value.start_cmd
      type         = proc.value.type
    }
  }
}
