I have only 1 node cluster and hence I need only 1 shard and 0 replica for all my indices. I cannot set the number of replica to 0 for metricbeat index. My yml file looks like this:
    setup.template.name: "metricbeat"
    setup.template.pattern: "metricbeat-*"
    setup.template.overwrite: true
    setup.template.enabled: false
    setup.template.settings:
      index.number_of_shards: 1
      index.number_of_replicas: 0
      index.codec: best_compression
What am I missing?
Sorry forgot to mention this is for version 7.10
