[bug] using args.partition causes unknown flag

tkam8 commented 5 years ago

Description

When running below command to launch chart to deploy the controller, k8s controller pod goes from "Error" to "CrashLoopBackOff " and never gets created.

helm install --set args.bigip_url=1.2.3.4 --set args.partition=kubernetes --set bigip_login_secret=bigip-login --set serviceaccount=k8s-bigip-ctlr f5-stable/f5-bigip-ctlr

Repro:

Install k8s
setup flannel and setup BIG-IP dummy node
setup bigip serviceaccount as necessary
setup secret for bigip login
install helm client and tiller
run helm install command as shown above using parameter "args.partition"
workaround is to change the parameter name to "bigip_partition"

Expected Behavior: Pod gets created

Actual Behavior: error

Request: please update the documentation if bigip_partition should be used as the parameter name when using the --set option.

Update:

upon further inspection, it looks like "helm inspect values" shows the right parameter name so should be sufficient documentation. I don't know where "args.partition" is valid, though. Any ideas?
