setup
command
editSets up the initial environment, including the ES index template, and ILM policy and write alias
- The index template ensures that fields are mapped correctly in Elasticsearch. If index lifecycle management is enabled it also ensures that the defined ILM policy and write alias are connected to the indices matching the index template. The ILM policy takes care of the lifecycle of an index, when to do a rollover, when to move an index from the hot phase to the next phase etc.
Use this command if you want to set up the environment without actually running Journalbeat and ingesting data.
