Grant privileges and roles needed for publishing

edit

Users who publish events to Elasticsearch need to create and write to Functionbeat indices. To minimize the privileges required by the writer role, use the setup role to pre-load dependencies. This section assumes that you’ve run the setup.

When using ILM, turn off the ILM setup check in the Functionbeat config file before running Functionbeat to publish events:

setup.ilm.check_exists: false

To grant the required privileges:

  1. Create a writer role, called something like functionbeat_writer, that has the following privileges:

    The monitor cluster privilege and the create_doc privilege on functionbeat-* indices are required in every configuration.

    Type Privilege Purpose

    Cluster

    monitor

    Retrieve cluster details (e.g. version)

    Cluster

    read_ilm

    Read the ILM policy when connecting to clusters that support ILM. Not needed when setup.ilm.check_exists is false.

    Index

    create_doc on functionbeat-* indices

    Write events into Elasticsearch

    Index

    view_index_metadata on functionbeat-* indices

    Check for alias when connecting to clusters that support ILM. Not needed when setup.ilm.check_exists is false.

    Index

    create_index on functionbeat-* indices

    Create daily indices when connecting to clusters that do not support ILM. Not needed when using ILM.

    Omit any privileges that aren’t relevant in your environment.

  2. Assign the writer role to users who will index events into Elasticsearch.
