Hello!
I need a function to add a rollup to ILM.
Found something on github: https://github.com/elastic/elasticsearch/issues/48003 .
I've never worked with git, I don't know where to start.
Is there an instruction to install Elasticsearch from the github repository(Master or Fork )?
Can I add a commit(link: Commit) to an existing installed cluster (I installed it from a deb package), not connected to git? Or is it necessary to install a full fork that has this commit? Is it possible to apply the commit(5811deb580ed1d72e1b412d3d29418deeaac9317) to the main branch(elastic/Elasticsearch)?
How do I view the fork version? And will I be able to update the cluster after installation (for example, from version 7.16 to 7.17)?
