If you wish to read it, I would suggest either creating a method in your application that allows you to read it directly. Alternatively, you can SSH into the container and cat the file.

Note that having a txt file directly in the container will not persist through redeployments.
To fix this, mount a volume to your service.

Yeah that's exact problem I had (it doesn't persist). So I need to read it now without redeploy because there is already some data.

So SSH it's a only one way I have?

Yes.

As mentioned above, I would suggest mounting a volume to your service so the logs will persist.

Okay, thank you for help
