Recently, I had to import some AWS resources to terraform, and most things went smoothly, but some did not. More specifically, I have encountered this problem. And here is my reply how to deal with it now. In this post, I am going to be more elaborate about this issue. So, what exactly I have run into? Here is the code: Such bucket existed and I wanted to import this guy to terraform (the bucket was public). So, I typed terraform import 'aws_s3_bucket.my-bucket' 'my-bucket'  and pressed enter: Wait, what? I understand the force_destroy  argument (it is  false by default), because I had not specified it, but acl ? I have two grant blocks... and according to the documentation , acl conflicts with grant . So, how is it even possible? 🤔 It was tempting to run terraform apply command... so let's do that! And what happened? Terraform (or should I say aws provider?) ignored these grant blocks and removed some ACL (Access control list) records from my bu

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.
