Scenario:
|

1. Deploy k8s using fuel-ccp-installer
|
||||
2. Create a DaemonSet for nginx with image version 1_10 and
|
||||
update strategy RollingUpdate
|
||||
3. Wait until nginx pods are created and become 'ready'
|
||||
4. Check that the image version in the nginx pods is 1_10
|
||||
Check that the image version in the nginx daemonset is 1_10
|
||||
5. Change nginx image version to 1_11 using YAML
|
||||
6. Wait for 10 seconds (needs to check that there were
|
||||
no auto updates of the nginx pods)
|
||||
7. Check that the image version in the nginx daemonset
|
||||
is updated to 1_11
|
||||
Wait for ~120 sec that the image version
|
||||
in the nginx pods is changed to 1_11
|
||||
8. Rollback the nginx daemonset:
|
||||
kubectl rollout undo daemonset/nginx
|
||||
9. Check that the image version in the nginx daemonset is
|
||||
downgraded to 1_10
|
||||
Wait for ~120 sec that the image version
|
||||
in the nginx pods is downgraded to 1_10
