# This Fluentd configuration file specifies the colleciton
# of all Docker container log files under /var/lib/docker/containers/...
# followed by ingestion using the Google Cloud Logging API.
# This configuration assumes the correct installation of the the
# Google fluentd plug-in. Currently the collector uses a text format
# rather than JSON (which is the format used to store the Docker
# log files). When the fluentd plug-in can accept JSON this
# configuraiton file should be changed by specifying:
#    format json
# in the source section.
# This configuration file assumes that the VM host running
# this configuraiton has been created with a logging.write scope.
