So if you’re struggling to reach another Pod by its IP address, NetworkPolicy might be the reason. Wrapping up If you want a really excellent deep-dive on how a Pod gets an IP address then check out: How a Kubernetes Pod Gets an IP Address- an advanced-level blog on Pod IP address...
how to access the node and configure it from within a pod? any suggestion will be helpful. Scenario is like this: I have a pod running in a node in K8s cluster in GCP. I know only the name of the pod e.g. "test-pod". My requirement is to configure something in the node where ...
A Kubernetes service enables communication between nodes, pods, and users of your app (both internal and external) to the cluster.Kubernetes assigns a service an IP address on creation, just like a node or pod. These addresses get assigned from a service cluster's IP range; for example, ...
When I am going to use kubernetes to create a pod for this containter, how to write pod.yaml file? I guess it is something like following: apiVersion: v1 kind: Pod metadata: name: app-ykt labels: app: app-ykt purpose: ykt_production spec: containers: - name: a...
在kubernetes中如何debug一个运行失败的pod?首先可以过滤出非Running状态的podkubectl get pods --all-namespaces | grep -iv Running,pod最常见的错误状态是CrashLoopBackOff,这表示着这个pod在启动之后恰好crashes了,kubernetes接着尝试再去启动这个pod,但是pod最终还是启动失败了。
Attached to the pod, there seems to be no way internal of the running Pod to know which ip-address was assigned to the it by the loadbalancer, so how do you do get the external ip-address from inside a running Pod in a Kubernetes cluster? kubernetes ip-address Share Imp...
Monitoring Containers in Kubernetes Kubernetes takes the idea of container orchestration to the next level. It is an extensive system that manages a set of cluster nodes, with each node acting as a server for hosting multiple pods. Each pod can contain one or more containers running together. ...
name: pod-with-tcp-socket-healthcheck spec: containers: - name: redis image: redis # defines the health checking livenessProbe: # a TCP socket probe tcpSocket: port: 6379 # length of time to wait for a pod to initialize # after pod startup, before applying health checking ...
In some Kubernetes clusters (microk8s), the default Storage Class simply creates hostPath volumes, which are not explicitly tied to a particular node. In a multi-node cluster, this can create an issue when the pod is terminated and rescheduled on a different node, "leaving" all the persistent...
I use kubelet as kubelet will track the status of each pod inpod_startup_latency_tracker, and kubelet will watch for the status change of each pod. Also, kubelet is usually the first layer to process the pod status and it's a stable component (compared to other components in the cluster...
