docker - 带有 Calico 的 Kubernetes 集群 - 容器未出现并因 FailedCreatePodSandBox 而失败

转载作者：行者123 更新时间：2023-12-02 12:36:57

我使用 Calico 设置 kubernetes 集群作为 CNI 并且所有节点都可用，但是当尝试使用图像 nginx 运行容器时，POD 仍然处于 creatingContainer 状态 - 我检查了/etc/cni/net.d 和/opt/cni/主节点和工作节点上的 bin，它们存在于所有节点上(1 个主节点和 1 个工作节点)。

在工作节点上，NGINX 试图启动但退出，我不确定这里发生了什么 - 我是 kubernetes 的新手并且无法解决这个问题 -

最佳答案

您需要在 kubernetes 上运行 calico 节点，然后确保在主机上使用/var/lib/calico 挂载 calico 节点

关于docker - 带有 Calico 的 Kubernetes 集群 - 容器未出现并因 FailedCreatePodSandBox 而失败，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/55206446/

kubernetes - Kubernetes 调度器依赖于哪些指标？
Kubernetes 调度程序是仅根据请求的资源和节点在服务器当前快照中的可用资源将 Pod 放置在节点上，还是同时考虑节点的历史资源利用率？最佳答案在官方Kubernetes documenta
kubernetes - kubernetes 命名空间中部署定义的唯一性
我们有多个环境，如 dev、qa、prepod 等。我们有基于环境的命名空间。现在我们将服务命名为 environment 作为后缀。例如。， apiVersion: apps/v1
kubernetes - Kubernetes 中命名空间的使用
我有一个关于命名空间的问题，并寻求您的专业知识来消除我的疑虑。我对命名空间的理解是，它们用于在团队和项目之间引入逻辑边界。当然，我在某处读到命名空间可用于在同一集群中引入/定义不同的环境。例如测
kubernetes - Kubernetes 中用户或角色的命名空间

kubernetes - Kubernetes 中的服务位于何处？
我正在学习 Kubernetes，目前正在深入研究高可用性，虽然我知道我可以使用本地(或远程)etcd 以及一组高可用性的控制平面(API 服务器、 Controller 、调度程序)来设置minio
kubernetes - Kubernetes 中的服务帐户和上下文有什么区别？
两者之间有什么实际区别？我什么时候应该选择一个？例如，如果我想让我的项目中的开发人员仅查看 pod 的日志。似乎可以通过 RoleBinding 为服务帐户或上下文分配这些权限。最佳答案什么是服
kubernetes - Kubernetes 上基于时间的容器调度？
根据基于时间的计划执行容器或 Pod 的推荐方法是什么？例如，每天凌晨 2 点运行 10 分钟的任务。在传统的 linux 服务器上，crontab 很容易工作，而且显然在容器内部仍然是可能的。然而
kubernetes - kubernetes 中的入口和服务网格有什么区别？
有人可以帮助我了解服务网格本身是否是一种入口，或者服务网格和入口之间是否有任何区别？最佳答案 “入口”负责将流量路由到集群中(来自 Docs:管理对集群中服务的外部访问的 API 对象，通常是 HT

kubernetes - Kubernetes 上的批处理
这里的任何人都有在 kubernetes 上进行批处理(例如 spring 批处理)的经验？这是个好主意吗？如果我们使用 kubernetes 自动缩放功能，如何防止批处理处理相同的数据？谢谢你。最
kubernetes - 避免 kubernetes 调度程序在 kubernetes 集群的单个节点中运行所有 pod
我有一个具有 4 个节点和一个主节点的 Kubernetes 集群。我正在尝试在所有节点中运行 5 个 nginx pod。目前，调度程序有时在一台机器上运行所有 pod，有时在不同的机器上运行。如
