This was originally submitted to pick up v0.3.1 of the cloud logging plugin which had a fix for the name 'metadata' failing to resolve. Since new releases of google-fluentd have this fix, it is no longer required. I've done some additional testing of 'gem update' behavior in the interim and I think it is ok to use in targeted situations, but we should not be doing an unconstrained update in general. The issue is that updating a gem may bring new dependencies, some of those dependencies may include native code, so it may try to launch a compiler, which isn't desirable and prone to failure. If we do need to grab an updated gem in the future we should specify an explicit version and the --minimal-deps flag.

# This Dockerfile will build an image that is configured to use Fluentd to
|
|
# collect container log files from the specified paths and send them to the
|
|
# Google Cloud Logging API.
|
|
# The environment variable that controls which log files are collected is
|
|
# FILES_TO_COLLECT. Files specified in the environment variable should be
|
|
# separated by whitespace, as in "/var/log/syslog /var/log/nginx/access.log".
|
|
# This configuration assumes that the host performing the collection is a VM
|
|
# that has been created with a logging.write scope and that the Logging API
|
|
# has been enabled for the project in the Google Developer Console.
