Add some additional init container tests that work via monitoring
container lifetime based on logs written to a common file. This allows
more easily writing assertions about the container lifetimes with
respect to one another.
Currently we only cleanup on exit. Let's trap SIGINT (ctrl-c) too, so we
always cleanup everything.
Otherwise if we ctrl-c is easy to leave something running, specially if
we ctrl-c while the cleanup function is running. And when we leave
something running and don't reused the certs ($REUSE_CERTS), that is the
default, something is left running and it fails with weird ways as we
can't auth with the new certs.

6f2cd1b5bd swapped the order of cancel() and
closeFn() so that closeFn got called first when the test was done. This caused
it to block while waiting for goroutines which themselves were waiting for
the context cancellation. The test still shut down, it just took ~86s instead
of ~30s.
The fix is to register the cancel twice: once as soon as the context is
created (to clean up in case of an unexpected panic) and once after
closeFn (because then it'll get called first, as before).
https://github.com/kubernetes/kubernetes/pull/109728 added a
golangci-strict.yaml where gingkolinter and stylecheck (some recent additions
to golangci.yaml) were missing.
To prevent such mistakes in the future, lines that are intentionally different
get annotated with a comment about golangci-strict.yaml or golangci.yaml.
Then a suitable diff command in the new verify-golangci-lint-config.sh checks
that only such lines, comments and blank lines are different.
When using JSON as output format, we want objectReference values to be
represented as a struct. For example, "item" is such a value:
{"ts":1678135015708.349,"caller":"garbagecollector/garbagecollector.go:595","msg":"classify object references","v":5,"item":{"name":"dra-test-driver-g4tkd","namespace":"dra-1830","apiVersion":"v1","uid":"c3f88616-7282-488c-887c-3f04291e6f4f"},"solid":null,"dangling":[{"apiVersion":"apps/v1","kind":"ReplicaSet","name":"dra-test-driver","uid":"dbe9a90c-9dfd-4ad0-8395-e5fa228f9851","controller":true,"blockOwnerDeletion":true}],"waitingForDependentsDeletion":null}
This PR sets higher priority to the `share-processes` flag than
provided profile.
For example, if user tries to use copy-to debugging with restricted
profiling, share process namespace should be false if user explicitly
disables it via `--share-processes=false`.
The test creates a Service exposing two protocols on the same port
and a backend that replies on both protocols.
1. Test that Service with works for both protocol
2. Update Service to expose only the TCP port
3. Verify that TCP works and UDP does not work
4. Update Service to expose only the UDP port
5. Verify that TCP does not work and UDP does work
