Hello,  
Im completely new to ES 🙂

I create some indices and index template - "logs", with a datastream.

The index template is attached to an Index Lifecycle Policy with automatic rollover (default settings (30 days or 50GB)).

Now, I can see that I have an index that is called ` .ds-logs-2022.08.25-000001` that backing up my datastream.  
But, when I have rollover every 30days, having the date as part of the index is pretty useless...

\*\* I didn׳t create any alias when creating my index template...

What should I do if I want my indicies to be like `.ds-logs-000001` ? (and after 30 days: `.ds-logs-000002`)

Welcome.

You should not really worry about this.  
If you create a datastream `logs`, the only index you should look at is `logs` which is indeed an alias behind the scene.

You should not try to use the concrete index names IMO.
