No information how using docker image for spyt cluster

[ykuc]

We want to change Python version in spyt cluster, but on the exec nodes has only python3.8

We were advised to use a docker image.

spark-launch-yt \
--params '{operation_spec={tasks={history={docker_image="MY_DOCKER_IMAGE"};master={docker_image="MY_DOCKER_IMAGE"};workers={docker_image="MY_DOCKER_IMAGE"}}}}'

image can be like this. But it is too much for us... May be need only openjdk-11-jdk , unzip , python and spyt libs...

Could you publish base spyt docker image and add information in docs?

Hello,
I can add docs for it.
Could you help me with the correct place for:

• docker image example
• doc

Look like there.
add docket example for on page or better on GitHub and link at doc?

@ykuc Hello. Documentation is in our main ytsaurus repository. You can find the required page here: https://github.com/ytsaurus/ytsaurus/blob/main/yt/docs/en/user-guide/data-processing/spyt/cluster/configuration.md
