apply with -e jsonnet fails

[williamhbaker]

Applying a jsonnet template causes an error when using the CLI with a cloud host, and will soon cause an error with an OSS host: influxdata/influxdb#23030

To reproduce, the file at https://github.com/influxdata/influxdb/blob/master/pkger/testdata/bucket_associates_labels.jsonnet can be used with influx apply -e jsonnet -f bucket_associates_labels.jsonnet with the file saved locally, or even influx apply -e jsonnet -u https://github.com/influxdata/influxdb/blob/master/pkger/testdata/bucket_associates_labels.jsonnet for a hosted file.

Since server-side jsonnet parsing is now disabled, we will need to parse it in the client to be able to handle jsonnet templates.

The CLI does seem to be able to parse jsonnet templates, the error seems to be somewhere else. If you run the command listed above as:

cat ./bucket_associates_labels.jsonnet | influx apply -e jsonnet

it works as expected and causes no issues. So I think this issue is something else other than the server losing jsonnet parsing abilities, and is somewhere in its handling of the -f flag
