can't instantiate chameleoncloud example

[ivotron]

This is the example:

provider:
  type: chameleonbaremetal
  key_name: 'enos-key'
  image_name: CC-Ubuntu14.04-Docker
resources:
  storage:
    control: 1
    network: 1

This is the output:

Hi @ivotron

If you are using https://chi.tacc.chameleoncloud.org the shared net name should be : shared-subnet1. See https://enos.readthedocs.io/en/stable-ocata/provider/openstack.html#id4

The configuration should look like :

provider:
  type: chameleonbaremetal
  key_name: #your key name
  walltime: '2:00:00'
  subnet: {'name': 'shared-subnet1'}
resources:
  compute:
    control: 1
    network: 1
    compute: 1

Moreover I suggest you to update enos to the latest version since #171 has been fixed recently.

[ivotron]

Thanks a lot. Updated and fixed YAML:

provider:
  type: chameleonbaremetal
  key_name: mykey
  image_name: CC-Ubuntu14.04-Docker
  subnet: {'name': 'shared-subnet1'}
resources:
  storage:
    compute: 1

Can I bother with one more question related to this? Is it possible to provide the key name via an environment variable? That would make it easier to re-use/share a reservation YAML file between multiple users (and would also be useful for automated tests).

After using the above reservation.yaml now I get the following:

The instance gets launched successfully on chameleon. I also tried to use destroy unsuccessfully:

Thanks!

See below for a minimal configuration file. Maybe you missed the inventory. The inventory will be looked up in the source if not found from your local directory.

Note also that to get a functionnal deployment you need one control, one network and at least one compute role.

@ivotron any progress ?

[ivotron]

after adding missing YAML elements, all worked OK. Thanks!
