如何从 Kubectl Output 中过滤掉字符串 pod/

Question

So I am trying to write a for loop to gather all of the described information from the following command across all pods within all namespaces.

kubectl describe pod <pod_name>

I am using the following command to generate output within the system:

kubectl get pods --all-namespaces -o Name 

This provides output similar to the following:

pod/compose-78f95d4f8c-zppf2
pod/compose-api-6ffb89dc58-5rk84
pod/coredns-5644d7b6d9-4qh7k
pod/coredns-5644d7b6d9-s946h
pod/etcd-docker-desktop
pod/kube-apiserver-docker-desktop
pod/kube-controller-manager-docker-desktop
pod/kube-proxy-trdx5
pod/kube-scheduler-docker-desktop
pod/metrics-server-d58c94f4d-bvdbv
pod/storage-provisioner
pod/vpnkit-controller
pod/dashboard-metrics-scraper-c79c65bb7-s26tz
pod/kubernetes-dashboard-56484d4c5-xg7v6

My ultimate goal would be to use the following to gather all of the described pods for a text file later:

for i in $(kubectl get pods --all-namespaces -o Name); do kubectl describe pods $i; done >> cluster_description.txt

However, the pod/ portion causes an error and I am not able to see anything in the output as it is just empty bytes.

QUESTION: How can I strip off the pod/ portion from the following command so I can get the output I want?

(kubectl get pods --all-namespaces -o Name

Answer 1

There is cut to splitting by '/' and getting second column cut -d'/' -f2 .

$(kubectl get pods --all-namespaces -o Name | cut -d'/' -f2)

Answer 2

kubectl describe pod -A > cluster_description.txt

-A --all-namespaces
