Packer: met an error with the msg "* Get /: unsupported protocol scheme """, what does it mean?

[Gary-Xie]

When I try to build an image with openstack builder in my private openstack, I met the error like below.

ubuntu@testtrusty:~$ packer build -debug openstack.json
Debug mode enabled. Builds will not be parallelized.
openstack output will be in this color.

1 error(s) occurred:

* Get /: unsupported protocol scheme ""

This is my template json file. Please double check it.

Duplicates #2597

[Gary-Xie]

yes, duplicated. And I find the solution in #2595 to set env variables including OS_AUTH_URL, OS_USERNAME,OS_PASSWORD and OS_TENANTNAME. But I still insist it is a bug. I think it should output some useful and meaningful error msg. And I don't know why these variable couldn't be read from json file as I defined.

[geefinator]

+1, not sure when this broke exactly but I know for a fact it did used to pull this out of the config and not rely on the ENV variables, because my images were working up until just recently. Frustrating.

[rickard-von-essen]

The docs have been updated, see Docs OpenStack until next release when the site will be updated.

Closing this in favour of #2597
