shimizukawa/fluentd repository overview

⁠Docker fluentd

Docker image with:

• fluentd⁠
• fluent-plugin-elasticsearch
• fluent-plugin-record-modifier
• fluent-plugin-exclude-filter

which do nothing by default.

Elasticsearch info is controlled by ES_HOST and ES_PORT variables which will be overwritten if you link elastic search container.

Fluentd config is created using /app/config/fluentd.conf.erb template and could be easily overwritten in custom Dockerfile:

If you want to override it dynamicaly, you can use volume for it.

-v /path/to/fluentdconfdir:/etc/fluentd
