Terraform - Create two buckets in two different regions using meta-argument
Let's say that you provision your AWS resources by Terraform , and mostly you keep everything in Oregon region, but you have some S3 buckets in another region (California for example). How you can deal with that? You can specify a meta-argument provider for a specific resource! Firstly, you must define two providers (default one for Oregon, and another one for California): The alias is very important, we are going to use it in a minute 🏃♂️ Now, let's create two buckets, one in Oregon and another one in California: For bucket in Oregon, we do not have to specify a provider because: By default, Terraform interprets the initial word in the resource type name (separated by underscores) as the local name of a provider, and uses that provider's default configuration. In our example, it is "aws". For bucket in California we must select another provider. And for that we use alias "california" ( aws.california ). That's it, folks.
