Add host via vSphere plugin

Hi all,

I am trying to build up new hosts in vSphere datacenter via Rancher plugin. I am stuck with item “OS ISO URL”. Did a try with URL to github for boot2docker.iso (https://github.com/boot2docker/boot2docker/releases/download/v17.09.1-ce/boot2docker.iso), did a try dosens of variatnions of local datastore path, but no success. Build process end up with: Error in driver during machine creation: open ‘https://github.com/boot2docker/boot2docker/releases/download/v17.09.1-ce/boot2docker.iso’: no such file or directory. What may be wrong? How to specific path for local datastore when datastore is [Test_Test_900] with path “/iso/boot2docker.iso”? Thanks.
