# This Dockerfile will build an image that is configured
|
|
# to run Fluentd with an Elasticsearch plug-in and the
|
|
# provided configuration file.
|
|
# The image acts as an executable for the binary /usr/sbin/td-agent.
|
|
# Note that fluentd is run with root permssion to allow access to
|
|
# log files with root only access under /var/log/containers/*
|
|
|
|
# 1. Install & configure dependencies.
|
|
# 2. Install fluentd via ruby.
|
|
# 3. Remove build dependencies.
|
|
# 4. Cleanup leftover caches & files.
