Discussion:
Context: NodeSwap feature gate was recently . Currently, as per , swap is only supported with cgroup v2 - cgroup v1 is no longer supported. For this reason, we decided to fail kubelet if NodeSwap feature gate is enabled and the node runs with cgroup v1. This would help prevent any surprises for the user by failing as soon as possible. This effort is being implemented in this PR: The problem: Currently, swap jobs are running with cgroup v1. Swap tests were in a way that they first check on which environment they're being run (e.g. which cgroup version? is NodeSwap FG enabled? Which swapBehavior is defined? etc) and then expect the right behavior to take place. With v1, the tests expect the containers to be defined without swap access. While the tests pass, they are much less valuable, since all they check is that swap is disabled for v1 workloads. The tests would be much more valuable if they would run with v2, therefore actually ensure that proper swap limitations are configured. In addition, is dependent on these changes, since as of now the jobs immediately fail with this PR since kubelet fails on an environment with cgroup v1 and swap enabled. What needs to change: [x] CRI-O swap related jobs should be defined to run with cgroup v2 (e.g. ) [x] containerd swap related jobs should be defined to run with cgroup v2 (e.g. ). Future work: In the future, we might consider introducing more jobs to check swap. Ideally, both and would be tested, perhaps by periodic jobs.
