Configuration

  • I created a parsers.conf file to have option to add custom parsers. FIle is basically a copy from fluent-bit github repository. File location /addon_configs/144431fc_fluent_bit/parsers.conf, Link to the file in Resources
  • If you do not need custom parsers and parser.conf file, skip file creation and remove Parsers_File line from SERVICE definition
  • Create /addon_configs/144431fc_fluent_bit/fluent_bit.conf

fluent_bit.conf
