How do I get a single pod name for kuberenetes?

I'm looking for a command like "gcloud config get-value project" that retrieves a project's name, but for a pod (it can retrieve any pod name that is running). I know you can get multiple pods with "kubectl get pods", but I would just like one pod name as the result.

I'm having to do this all the time:

kubectl get pods # add one of the pod names in next line
kubectl logs -f some-pod-frontend-3931629792-g589c some-app


I'm thinking along the lines of "gcloud config get-value pod". Is there a command to do that correctly?

You can use the grep command to filter any output on stdout. So to get pods matching a specified pattern you can use a command like this:

> kubectl get pods --all-namespaces|grep grafana


Output:

monitoring kube-prometheus-grafana-57d5b4d79f-smkz6 2/2 Running 0 1h


To only output the pod name, you can use the awk command with a parameter of '{print $2}', which displays the second column of the previous output:

awk

'{print $2}'

kubectl get pods --all-namespaces|grep grafana|awk '{print $2}'


To only display one line you can use the head command like so:

head

kubectl get pods --all-namespaces|grep grafana|awk '{print $2}'|head -n 1


There are many ways, a quick search you can find many solutions:

kubectl get pods -o name --no-headers=true

kubectl get pods -o name --no-headers=true

kubectl get pods -o=name --all-namespaces | grep kube-proxy

kubectl get pods -o=name --all-namespaces | grep kube-proxy

kubectl get pods -o go-template --template '{{range .items}}{{.metadata.name}}{{"n"}}{{end}}'

kubectl get pods -o go-template --template '{{range .items}}{{.metadata.name}}{{"n"}}{{end}}'
