My first effort to create a stack using Heat failed, and I'd appreciate any tips on how to get past that.

My source is the Stein Heat Getting Started page, https://docs.openstack.org/heat/stein.... I have created a Controller and two Compute nodes using the Stein installation guides (Ubuntu).

My first issue was in not being able to wget the Fedora image referenced in the Getting Started page. I found an almost-similarly named image at https://archives.fedoraproject.org/pu... and used it instead.

Then I discovered that not having a flavor was slowing me down, so I created one:

$ openstack flavor create --disk 3 m1.small

Then the create command:

$ openstack stack create \
  -t http://git.openstack.org/cgit/openstack/heat-templates/plain/hot/F20/WordPress_Native.yaml \
  --parameter key_name=heat_key --parameter image_id=fedora-20.x86_64 \
  --parameter instance_type=m1.small \
  teststack

Here is the result:

$ openstack stack event list teststack

2019-10-28 17:03:03Z [teststack]: CREATE_IN_PROGRESS  Stack CREATE started
2019-10-28 17:03:03Z [teststack.wordpress_instance]: CREATE_IN_PROGRESS  state changed
2019-10-28 17:03:03Z [teststack.wordpress_instance]: CREATE_FAILED  ValueError: resources.wordpress_instance: nics are required after microversion 2.36
2019-10-28 17:03:03Z [teststack]: CREATE_FAILED  Resource CREATE failed: ValueError: resources.wordpress_instance: nics are required after microversion 2.36

So does this mean I have to create some nics? If so, how? Or should I be using a different image (like the cirros image that came with the Stein Glance installation? Or something else altogether?

You don't have a networks parameter in your OS::Nova::Server resource section, this will be needed for having nic configuration of your VM. You have to find out the network to which the VM has to attach upon spawning. Something like below in your nova compute resource section

networks: public_net or private_net

I need to study the communications burden between the Controller and the Compute nodes created by orchestration services (my environment is bandwidth-limited). Your tip about the networks property should get me over the hump. The "start small" idea is why I started with the Getting Started page and then tried the HOT Hello World page, which gave the same error.

Thanks again for the feedback.
