[fix] AWS S3 make_bucket failed: An error occurred (InvalidBucketName) when calling the CreateBucket operation.

% aws s3 mb s3://c2c-bucket-A2

make_bucket failed: s3://c2c-bucket-A2 
An error occurred (InvalidBucketName) when calling the CreateBucket operation: 
The specified bucket is not valid.

If you receive a make_bucket failed error when you try to create an AWS S3 bucket using the CLI command, then the reason is as specified - InvalidBucketName, to understand it better you will need to understand the rules of creating an S3 bucket name,

Rules for Creating S3 Bucket Names:

Should be unique across AWS regions. So it could be it's already taken.
Cannot have uppercase letters.
Should be between 3 and 63 characters.
Names can only start with lowercase letters and numbers.
Only dot (.) and dash/hyphen (-) are allowed as special characters.
Cannot contain two adjacent dots.
Cannot be like IP addresses eg 192.168.0.1
Cannot start with xn-- prefix
Cannot end with -s3alias as suffix.
Cannot have dots if used with AWS S3 Transfer Acceleration.
You cannot change the bucket name once it is created.

So as you can see, in this case, the bucket creation failed because I used an Uppercase letter in the bucket name.
