Plan: 0 to add, 4 to change, 0 to destroy.

It seems that our current configuration will not recreate instance since the default value of user_data_replace_on_change should be by default false and we are not setting it to true, but I think I will be much more confident once I use explicit statement of user_data_replace_on_change = false. What do you think @adgud ?

You can update that, sure. It's known behaviour in EC2 but being more explicit won't hurt anyone.

Terraform plan apllied, @MSzalowski added to the .ssh/authorized_keys.
