ruby-on-rails - Fluentd 隐藏密码或在配置中加密

Question

由于安全原因，我们不能保持纯文本的 SQL 身份验证，有没有办法隐藏或加密密码？

<source>
  @type sql
  @id output_sql
  host "sqlserverhost.aws_region.rds.amazonaws.com"
  database db_name
  adapter sqlserver
  username user
  password pwd
  tag_prefix myrdb # optional, but recommended
  select_interval 60s # optional
  select_limit 500 # optional
  state_file /var/run/fluentd/sql_state
  <table>
    table tbl_name
    update_column insert_timestamp
  </table>
</source>

<match **>
  @type stdout
</match>
