Kubectl get resources in all namespaces

kubectl api-resources enumerates the resource types available in your cluster. this means you can combine it with kubectl get to actually list every instance of every resource type in a namespace: kubectl api-resources --verbs=list --namespaced -o name \ | xargs -n 1 kubectl get --show-kind --ignore-not-found -l <label>=<value> -n <namespace. @fabianofranz: Yes, limits are covered there (Rule 2: No namespace admin level resources (limits, quota, policy, authorization rules)).. This leaves me frustrated though: kubectl help get describes kubectl get all as List all resources with different types. so I think I am right to expect all resources to be listed.; It might be ok if adminstrative resources are hidden from a normal user

The Namespaces allow to partition physical resources into the logically named groups, allowing a Kubernetes cluster to share resources between multiple groups. In this note i will show how get the current Namespace and how to list all Namespaces in Kubernetes cluster using the kubectl command kubectl top pod allows one to see the most resource hungry pods, but the ordering isn't always intuitive, especially if one is examining --all-namespaces.. sort to the rescue!. To sort the output of kubectl top pod --all-namespaces, pipe it to sort:. kubectl top pod --all-namespaces | sort --reverse --key 3 --numeric \ | head -10 kubectl top pod --all-namespace Prints the top information of.

GitHub - corneliusweig/ketall: Like `kubectl get all`, but

Resource quotas allow you to place limits on how many resources a particular namespace can use. Depending on how you have chosen to use namespaces in your organization, they can give you a powerful way to limit the resources that are used by a particular team, application, or group of applications, while still giving developers the freedom to tweak the resource limits of each individual container Listing resources. There are a ton of different resources in Kubernetes. The most simple way to list resources is to just use kubectl get: kubectl get pods. kubectl get services. kubectl get deployments. The three commands above can all be run in one command by comma-separating the resources: kubectl get pods,services,deployments kubectl get pods --all-namespaces. Below command is used to get details of the pod. kubectl api-versions. kubectl api-resources -o wide. Api-versions for few of the k8s objects Monitoring Containers. To inspect the resources consumed by the containers in a pod, add the flag --container to the top command as follows: kubectl top pods --all-namespaces --containers.
