Q:

Create an alias for a AWS S3 bucket

Is it possible to setup a working bucket or to setup an alias for a bucket in AWS S3 CLI console? Because for every single command you have to enter the bucket path and I could't find a solution.

A:

There IS an alias capability for the AWS Command-Line Interface (CLI). See:

AWS re:Invent 2016: The Effective AWS CLI User (DEV402)
GitHub - awslabs/awscli-aliases: Repository for AWS CLI aliases.

It can be used to substitute whole commands, but I'm not sure if it can be used to substitute variables within a line. For that, just use your the capabilities of your OS, eg:
$ my_bucket=s3://my-bucket/
$ aws s3 ls $my_bucket
