MOS7, MU3, with reduced footprint, Fuel still requires a physical MongoDB host

[ZHI BING WANG]

I want to put all nodes in control plane in KVM. However, before I can spawn vms it requires a physical MongoDB host.

If we are using virt role, it should not requires it.

To reproduce it,

use Fuel 7, MU3, reduced footprint,
enable ceilometer,
then try to spawn vms

@ZHI BING WANG, please put detailed steps to reproduce to this bug.

[ZHI BING WANG (zwang)]

Install Fuel 7, MU 3
Enable reduced footprint
https://docs.mirantis.com/openstack/fuel/fuel-7.0/operations.html#using-the-reduced-footprint-feature

Create an environment, and enable ceilometer

setup KVMs on virt host like this:
fuel2 node create-vms-conf 9 --conf '{"id":1,"mem":40,"cpu":8}' '{"id":2,"mem":20,"cpu":4}' '{"id":3,"mem":20,"cpu":4}' '{"id":4,"mem":8,"cpu":4}' '{"id":6,"mem":8,"cpu":4}'

Then spawn:
fuel2 env spawn-vms 2 --debug

Then, in Fuel webUI, you will see it complains something like, it requires at least one MongoDB server ...

Adding to the above,

the physical hosts used like this:
1. Fuel
2. a Compute
3. 3 virt hosts

No other roles should be required.

Dmitry, MOS Maintenance has less expertise in this area than Fuel Sustaining.

I was able to successfully deploy environment with ceilometer on
virtualized controllers. Please check attached screenshot. Here
are the steps it took:

1. Enable the Advanced feature group in Fuel. On the Fuel Master
node edit the /etc/fuel/version.yaml file and add advanced under
feature groups there.

2. Having added "advanced" to the yaml file, issue the following
commands:

    dockerctl shell nailgun
    supervisorctl restart nailgun

3. Create new env (use tunneling networking, enable Ceilometer feature)

4. Assign the "virt" role to the discovered node using Fuel UI

5. Upload the virtual machine configuration on Fuel UI:

    [{"mem":2,"id":13,"cpu":1,"vda_size":107374182400},{"mem":2,"id":14,"cpu":1,"vda_size":107374182400},{"mem":2,"id":15,"cpu":1,"vda_size":107374182400}]

6. Provision the bare metal node with the virtual role and
spawn virtual machines:

    fuel2 env spawn-vms 3

7. Configure and deploy controller with ceilometer

I assume that bug reporter activated 'Use external Mongo DB' checkbox.

Anyway, this bug is not reproducible with latest updates, closing bug as Invalid.
