Works for me. We could optionally update the initial paragraph to say that it is suitable for kubernetes and refer to the helm chart docs page as well

[nineinchnick]

Docker is not the only runtime that can be used to run Trino in a container. We do publish a Docker image to Docker Hub thought.

@nineinchnick @colebow and @findepi .. I think we should add a sentence to the intro paragraph that says that:

• The docker image is published to dockerhub
• It can be used with the docker runtime, but also other runtimes
• it is used by the helm charts for usage on k8s (and link to that page in the docs) and probably link from that page back to here..

Let's do that all in this PR since we are already on it..

I'm going to keep the edits minimal because of a section slightly lower down:

.. note::

   There are multiple ways to use Trino within containers. You can either run
   Trino in Docker containers locally, as explained in the following sections,
   or use a container orchestration platform like Kubernetes. For the Kubernetes
   instructions see :doc:`/installation/kubernetes`.

Fair

[findepi]

I don't see why we're adding this sentence. Why not just update the title?

We don't need to specify with runtimes run docker images, just like we don't really define what "a docker image" is.

[colebow]

I think it's good to be clear that this isn't the only way to do things / you don't have to follow this guide.

[mosabua]

I think this is helpful and clarifying and does not do any harm. I would leave as is and merge. Specifically also since the new title narrows the scope .. and is kind of misleading therefore, this sentence clarifies.

[mosabua]

@electrum @findepi could we merge this one as well?

Thank you @findepi !
