Kubernetes client is incompatible with evenlet and breaks the periodic
|
|
tasks. After kubernetes client 4.0.0 magnum is affected by the bug
|
|
below.
|
|
https://github.com/eventlet/eventlet/issues/147
|
|
Magnum has three periodic tasks, one to sync the magnum service, one to
|
|
update the cluster status and one send cluster metrics The send_metrics
|
|
task uses the kubernetes client for kubernetes clusters and it crashes
|
|
the sync_cluster_status and send_cluster_metrics tasks.
|
|

|
|
Additionally, the kubernetes scale manager needs to be disabled
|
|
to not break the scale down command completely. Note, that when magnum
|
|
scales down the cluster will pick the nodes to scale randomly.
|
|
|
|
upgrade:
|
|
- |
|
|
In magnum configuration, in [drivers] set send_cluster_metrics = False to
|
|
to avoid collecting metrics using the kubernetes client which crashes the
|
|
periodic tasks.
