In 1.9, kubernetes prompted Deployment to apps/v1 and finally deprecated
extensions/v1beta1 support in 1.16. Users will see the following error message
in log when fission components try to submit Deployment to the k8s API server
and specify extensions/v1beta1 as API group.
error: unable to recognize "deployment": no matches for kind "Deployment" in version "extensions/v1beta1"
This PR updates call to k8s API server and apiKind in chart files to avoid fission failure in 1.16.
This fix allows the empty repository tag in values.yaml file. The changes are done in the templates of deployment and fluentbit where repository tag will be added in the docker image name only when specified with some value in case of empty repository tag image name contain the name of image and tag only.
This removes fluentd in favor of using fluentbit, which is lighter (in
memory usage) and seems to be more actively maintained.
Fluentbit's config file format is different from fluentd's. It also
doesn't support the same record modification stuff that fluentd
supports, so we have to change the influxdb query slightly. This
means that after an upgrade, the new CLI may won't work for querying older
logs. Hopefully, this slight breakage is acceptable; if users
really need older logs they can use the older CLI.
