[Starlingx-discuss] question about LP1828056

[Wang, Jing (Angie)]

Hi Marin,

In the helm chart values.yaml , if the value has only numbers(at least 8), helm will cast it to float64. We need to add single/double quotes to the overrided value(if it contains only numbers) to force it to be a string, then helm would be able to parse it correctly.

Ie...
system helm-override-update -value panko.yaml
cat panko.yaml
conf:
  panko:
    database:
      event_time_to_live: "555555555555"

But I cannot override it with quotes added via system helm-override-update with --set option.

The openstack-helm LP you created https://bugs.launchpad.net/openstack-helm/+bug/1836744 is invalid. This is not related to openstack-helm.
There had couples of helm issues regarding to the float number, it fixed in commit https://github.com/helm/helm/pull/3599
So if you need to use -set-string option to override the value(if it contains only numbers and at least 8)
Ie. helm install panko -set-string conf.panko.database.event_time_to_live=24828899

Thanks,
-Angie

Hi folks

I work on LP1828056, https://bugs.launchpad.net/starlingx/+bug/1828056

Issue description:
After system deployed, begin to deploy openstack application
$ system application-upload <openstack application tarball>
$ system helm-override-update --set conf.panko.database.event_time_to_live=24828899 stx-openstack panko openstack
$ system application-apply stx-openstack

When deploy chart for osh-openstack-panko, it will deploy fail, with job panko-db-sync.
controller-0:~$ kubectl get jobs -n openstack | grep panko
panko-db-init                          1/1           37s        107m
panko-db-sync                          0/1           107m       107m
panko-events-cleaner-1563196200        0/1           90m        90m
panko-ks-endpoints                     1/1           67s        107m
panko-ks-service                       1/1           39s        107m
panko-ks-user                          1/1           62s        107m

check pod log, you will find in panko.con, "event_time_to_live = 2.4828899e+07", but it request a integer for db-sync.
/var/lib/kubelet/pods/73b84006-a6ff-11e9-ae87-525400d66765/volumes/kubernetes.io~secret/db-sync-conf/..2019_07_15_12_52_54.229165405/panko.conf
event_time_to_live = 2.4828899e+07

In /opt/platform/helm/19.01/stx-openstack/1.0-17/openstack-panko.yaml
  values:
    conf:
      panko:
        database:
          event_time_to_live: 24828899

So this is maybe tiller's issue. I find if set event_time_to_live to more than 6 digit value, it will generate a float value in panko.conf. Any idea about how to fix this issue?

Thanks!
