Kubernetes requires to disable the swap file at the OS level. ... What if for some reason resources are constrained within a host and the VMkernel applies one of its resource reclamation techniques? One of the feature that is in the first line of defense is the balloon driver. ... A cluster may stop working properly if a critical add-on is evicted.
However, if resources are in contention, and a pod is using resources beyond those it requested, and thereby causing excess demand on a node, the offending pod may be evicted from the node by Kubernetes and the associated Domino Run is terminated. For this reason, Domino strongly recommends setting the requests and limits to the same values.A larger value for maximum-dead-containers is also recommended for a similar reason. See this issue for more details. Deprecation. Some kubelet Garbage Collection features in this doc will be replaced by kubelet eviction in the future. Including:
The reason is simple: by using multiple capacity pools you: (a) increase the chances of getting Spot capacity, instead of trying to get Spot capacity from a single instance type in a specific AZ and failing if there's no spare capacity in that capacity pool. ... When called, the Lambda function calls the Kubernetes API to cordon, and evict ...
The reason being that administrating Elasticsearch can be a lot of work, as many people experienced with the system will tell you it can be tricky to keep running smoothly and that it’s a task better outsourced to an external service (i.e. Elastic Cloud). Official Kubernetes Add-On 今天上午一到工位，就收到来自同事的“投诉”：私有云上的Kubernetes cluster中的一个node似乎不工作了，因为专门部署于那个节点上的应用挂掉了，并且长时间没有恢复。
100 amp power supply for car audio displaysA good question came in for the Kubernetes course: "How to delete logs in ElasticSearch after certain period"? A good one this. The questioner was aware that you can issue a CURL command to ElasticSearch, specifying the name of an index to delete, but this doesn't feel very "kubernetes".This information is crucial for a scheduler to make "intelligent" decisions when calculating where to place containers. In this aspect, there is no essential difference between Kubernetes and Docker Swarm. Both are using requested resources to decide where to deploy containers and limits when to evict them.A side-effect of autoscaling is that pods may be created or evicted more frequently, as scale-out and scale-in events happen. To mitigate the effects of this: Use readiness probes to let Kubernetes know when a new pod is ready to accept traffic. Use pod disruption budgets to limit how many pods can be evicted from a service at a time.
