Kubernetes flow in case of pod crash

cn flag

Even if I don't configure any liveliness/Readiness probes, how Kubernetes detects my pod crash and then restart it. Can someone know the flow of Kubernetes in such case. Thanks

Kubernetes also detects if the process with ID 1 inside the container is still running. If not, it will restart the pod.

Thanks a lot @Johnson. It would be great if you can please share, how Kubernetes detects if the process with ID 1 is alive or not. Does it poll or it gets events ? If it is poll, how much is the polling interval(what is its configuration parameter). If it gets events, how is the delay being added in the event. Thanks

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
