Deploying openstack

sysnasri · 5 December 2020 14:54

I’m trying to deploy openstack with the this charm openstack lxd | Juju , unfortunately units cannot be installed due to the following errors :

ubuntu@juju-9711e5-7-lxd-2:/var/lib/juju/agents/unit-openstack-dashboard-1/charm$ ./hooks/install
dpkg-query: error: --status needs a valid package name but ‘python-dnspython,’ is not: illegal package name in specifier ‘python-dnspython,’: character ‘,’ not allowed (only letters, digits and characters ‘-+._’)

This might be a bug in the openstack-dashboard charm itself.
It would be worth filing a bug .

sysnasri · 7 December 2020 07:36

I don’t think it is only dashboard problem , all has the same issue please look at the image.

sysnasri · 7 December 2020 09:00

I would be happy if you let me know whether there is a command to list applications in specific model ?

Also if there is a re-run application model or something similar, the purpose is to rerun the installation procedure if I changed the something in underlying machines’ configuration.

For example, I forgot to add a secondary disk for openstack installation and the whole ceph units got stuck in " No block devices detected using current configuration " as result the installation did not complete and then I had to destroy the model and start from the beginning again.

So looking at the tracebacks provided:

is bug 1799500 that was fixed and released in the openstack-dashboard charm revision 274 (the bundle installs 271).

However, this part:

looks quite odd to me in that it seems to indicate that the juju provided binary of config-get could not be found on the path.

If you are looking to deploy openstack-on-lxd, might I suggest going through the in-depth readme available in the openstack-on-lxd repository.

The bundle itself needs to be updated in the charmstore as its pinning some older versions, but the ones available in the openstack-on-lxd repository should place you in better shape.

I deleted that model and installed base openstack from the following charm

cs:bundle/openstack-base-70

Everything is green except ovn-chassis which Cannot find device “eno2” on my machine which actually has 2 NICs.

Cannot find device “eno2”

@billy-olsen ,

To be honest I found out what I have missed during the deployment, I did not changed the network interface variable during the deployment.

variables:
  openstack-origin:    &openstack-origin     distro
  data-port:           &data-port            br-ex:eno2
  worker-multiplier:   &worker-multiplier    0.25
  osd-devices:         &osd-devices          /dev/sdb /dev/vdb

The question is: can I change the nic name now?

pmatulis · 10 December 2020 16:12

Alireza, you can try this (if eno2 is the interface):

juju config ovn-chassis bridge-interface-mappings=br-ex:eno2
