Customise host path

[amehub]

Description
Allow support of parameterised value for host path in the daemonset.yaml instead of assuming that the certificates are always under /etc.

Hi @amehub thanks for your feedback. Have a look at #95 and let me know what you think

Any update iam having my certificates in the host of the VM and iam having different paths instead of /etc. i added volumes and volumeMounts in the values.yaml but not reflecting inside the pod.

#95 is an open PR so you can't configure volume mounts in the current release. I'll make sure to have a working version of it released soon. It would help a lot if you could test it out in your environment. I'll let you know asap.

Just release 1.1.7 of the helm chart. Do helm repo update and you should see it. Then you should be able to perform a helm upgrade with an updated values.yaml file. For example:
