Summary: Support multiple versions of Kubernetes
Key: YUNIKORN-866
URL: https://issues.apache.org/jira/browse/YUNIKORN-866
Project: Apache YuniKorn
Issue Type: Improvement
Components: shim - kubernetes
Reporter: Craig Condit
As we approach 1.0, we should think about how we will target multiple versions
of kubernetes moving forward. Major vendors currently support versions as old
as 1.18 and as new as 1.22. Additionally, for upgrades, we should ideally be
building against the same version as the K8S cluster is running (+/- 1 version).
We also need to handle incompatibilities between old and new versions. For
example, issues such as YUNIKORN-625 cannot currently be resolved while
supporting such a wide version range, as APIs have transitioned from v1beta1 to
v1 and dropped support for v1beta1 between 1.18 and 1.22.
To work around this, we could target the latest available internally, but
modify build scripts to support building against older versions (possibly using
different go.mod / go.sum files). For the case of things like v1beta vs. v1 of
an API, we can use conditional compilation on the older versions to use the
beta API instead of v1.
