LOG_FORMAT is ignored? about fluentd-kubernetes-sumologic

That should work. I'll test it myself and get back to you.

More info. I tried to put the value "invalid" in the LOG_FORMAT var, and the container refuses to start:

2017-01-26 12:15:17 +0000 [error]: config error file="/fluentd/etc/fluent.conf" error="Invalid log_format invalid must be text, json or json_merge"

When reverting back to text, I get the JSON log back in Sumologic. I am using the hosted service.

In the output plugin, here the log_format contained in sumo_metadata owerwrites the log_format provided to the output plugin directly, which comes from here. So, the env var does not work.

[stevezau]

ah, i see the issue.

I believe by adding the below to source.containers.conf it should set the _sumo_metadata field correctly for the output plugin.

log_format "#{ENV['LOG_FORMAT']}"

Can you please let me know if you still have issues?

[mfornasa]

Works now.
