Container runtime engines, such as Docker’s runC, leverage OS-level virtualization capabilities offered from the kernel to create isolated spaces called “containers.” This virtualization makes it possible to efficiently deploy and securely run a container independently of the hosting infrastructure. Be...
当API server对pod发出新的请求时,kubelet与CRI-O守护进程交互,通过Kubernetes容器运行时接口启动所需的容器。 CRI-O使用 containers/image 库,根据配置的容器信息,检查并pull镜像。 CRI-O为容器生成OCI运行时规范(OCI specification ,JSON格式)。 CRI-O启动一个OCI兼容的运行时(runc),按照运行时规范启动容器进程。
使用Helm 部署 cert-manager:ServiceMonitor 可进行配置启用。 使用YAML manifests :首先,需要在 cert-manager 的部署 yaml 中追加 containers 部分;然后,创建一个 PodMonitor。 后续文章中会有如何进行完整的监控实践,敬请期待。 3. 与 Ingress 集成 cert-manager 中的一个组件 ingress-shim 负责通过向 Ingress 资源...
Kubernetes explained Modern applications are increasingly built using containers, which are microservices packaged with their dependencies and configurations. Kubernetes (pronounced “koo-ber-net-ees”) is open-source software for deploying and managing those containers at scale—and it’s also the Greek...
