# otherwise pods stops trying to resolve the domain.

# Kubernetes e2e tests use ginkgo and tags to select the tests that should run based on two regex, focus and skip:
# Focus tests:
# \[Conformance\]|\[sig-network\]: Conformance tests are defined by the project to guarantee a consistent behaviour and some mandatory features on all clusters
# sig-network tests are defined by sig-networkto guarantee a consistent behaviour on all the the k8s network implementations
# Skipped tests:
# Disruptive|Serial : require to run in serial and perform disruptive operations on clusters (reboots, ...)
# Federation|PerformanceDNS : unrelated sig-network tests
# Feature : skip features that are not GA, however, some of them should be enabled, per example [Feature:ProxyTerminatingEndpoints]
# DualStack : only with dualstack clusters
# KubeProxy|kube-proxy : kube-proxy specifics
# LoadBalancer|GCE|ExternalIP : require a cloud provider, some of them are GCE specifics
# Netpol|NetworkPolicy : network policies, demand significant resources and use to be slow, better to run in a different job
# Aggregator : Flaky, https://github.com/cilium/cilium/issues/24622.
# same.port.number.but.different.protocols|HostPort : #9207
# rejected : Kubernetes expect Services without endpoints associated to REJECT the connection to notify the client, Cilium silently drops the packet
# externalTrafficPolicy : needs investigation
