A dynamic block acts much like a for expression.
dynamic { }
Example
dynamic "parameter" {
for_each = var.parameters
content {
name = parameter.value.name
value = parameter.value.value
apply_method = lookup(parameter.value, "apply_method", null)
}
}
locals {
dynamic = "key_b"
my_map_json = jsonencode({
key_a = "something"
(local.dynamic) = "else"
})
# ...
}
