Adjust Fluentd source format for Docker files to be JSON for Cloud Lo…

…gging

@lavalamp because I have decided to diverge from the image update procedure followed elsewhere -- if we use the user kubernetes on Dockerhub then we don't need to use a Git hash -- right?
@mr-salty and @a-robinson for the config change

[a-robinson]

config change LGTM

[lavalamp]

...but we should never commit this to the code base, right?

[satnam6502]

Correct. After LGTM this should be changed to gcr.io/google_containers/fluentd-gcp:1.7
Does that make sense as a sane procedure for updating images?

[satnam6502]

Updated to gcr.io/google_containers/fluentd-gcp:1.7

[satnam6502]

I can observe correctly ingested log data in the Cloud Logging console from a cluster made with this PR.

[satnam6502]

I have now pushed the image to gcr.io.

$ make push
gcloud preview docker push gcr.io/google_containers/fluentd-gcp:1.7

All: is this LGTM-ed enough to merge?

[lavalamp]

gcr.io/google_containers

[satnam6502]

Likwise, this is for the test build of the image.

[lavalamp]

Oh-- sorry, I missed the k.

[lavalamp]

LGTM after fixing gcr.io/google_containers :)

[satnam6502]

I think this is ready to merge?

[fabioy]

Automatic merge failed. Can you check if rebase is needed? Thank you.

[satnam6502]

Fetched and rebased from head, pushed.
