To use, simply paste the following into a file named oci.tf in an eA second option is to simplify and use a second map, Using the merge () function. To merge two maps in Terraform, we primarily use the merge function. The merge function takes two or more maps as inputs and produces a single map that contains a union of the keys and values from all the input maps. When keys overlap, the value from the map that is later in the argument list will take precedence. The concat function combines two or more lists into a single list. Th 1. To concatenate variable with the string, use this syntax instead of join () : foo = "string-${var.bar}-a-string".
