Basing this action on push to `chart-*` tags doesn't work: the action itself
creates the new release tag, so trying to push the changes to a tag ends up
with the releaser comparing the changes to themself (and failing).
This also renames the chart from "descheduler" to "descheduler-helm-chart", to
avoid confusion with automated releases.
This moves the kind setup (previously used by Travis) to the e2e runner script
to accomodate the switch to Prow. This provides a KIND_E2E env var to specify
whether to run the tests in kind, or (by default) to run locally).
The matrix has been updated with the soon the be released v0.18
details. Also, clarified the descheduler and k8s version compatibility
requirements and recommendations.
Starting with descheduler v0.18 a release branch will be created for
each descheduler minor release. The release guide has been updated with
the steps to create release branches.
This increases the specificity of the RemoveDuplicates strategy by
removing pods which not only have the same owner, but who also
must have the same list of container images. This also adds a
parameter, `ExcludeOwnerKinds` to the RemoveDuplicates strategy
which accepts a list of Kinds. If a pod has any of these Kinds as
an owner, that pod is not considered for eviction.
The EvictPod function previously returned a bool and an error. The
function now only returns an error. Callers can check for failure by
testing if the returned error is not nil. This aligns the EvictPod
function with idiomatic Go best practices.
Also, the function name has been changed from EvictPod to evictPod
because it is not used outside the evictions package.
End users should be able to see the detailed error from the EvictPod
method when it fails. Updates all strategies to log the error. The
PodLifeTime strategy already logs this error.
In multi-tenant environments it is useful to know which namespace a pod
was evicted from. Therefore log the namespace when evicting pods.
Also, do not log a nil error when successfully evicting pods.
The new PodLifeTime descheduler strategy can be used to evict pods that
were created more than the configured number of seconds ago.
In the below example pods created more than 24 hours ago will be evicted.
