### 3. Configure `mc` and create another user user1 with attached policy user1policy

```
mc alias set myminio-admin1 http://localhost:9000 admin1 admin123 --api s3v4

mc admin user add myminio-admin1 user1 user123
mc admin policy attach myminio-admin1 user1policy ~/user1policy.json
mc admin policy attach myminio-admin1 user1policy --user=user1
```
