# Kubectl Grep [](https://circleci.com/gh/guessi/kubectl-grep) [](https://godoc.org/github.com/guessi/kubectl-grep) [](https://goreportcard.com/report/github.com/guessi/kubectl-grep) [](https://github.com/guessi/kubectl-grep/releases/latest) [](https://github.com/guessi/kubectl-grep/blob/master/go.mod) Filter Kubernetes resources by matching their names # Requirements - Kubernetes 1.17.0+ - Kubectl 1.17.0+ - Krew 0.4.0+ # Compatibility please refer to [Kubernetes version policy](https://kubernetes.io/docs/setup/release/version-skew-policy/#kubectl) and [CHANGELOG](CHANGELOG.md) for supported version matrix. Example: `kubectl-grep` build with Kubernetes-1.19.x should be compatable with Kubernetes cluster version 1.18, 1.19, 1.20. # Why we need it? playing with Kubernetes is my daily job, and I normally search pods by `pipe`, `grep`, `--label`, `--field-selector`, etc. while hunting abnormal pods, but typing such long commands are quite annoyed. Before change, we usually filter pods by the following commands, $ kubectl get pods | grep "keyword" $ kubectl get pods -o wide | grep "keyword" $ kubectl get pods -n "my-ns" | grep "keyword" $ kubectl get pods -A | grep "keyword" $ kubectl get pods -l "key=value" | grep "keyword" $ kubectl get pods -l "key=value" -n "my-ns" | grep "keyword" $ kubectl get pods -l "key=value" -A | grep "keyword" With this plugin installed, you can filter pod with `kubectl grep` easily $ kubectl grep pods "keyword" $ kubectl grep pods "keyword" -o wide $ kubectl grep pods "keyword" -n "my-ns" $ kubectl grep pods "keyword" -A $ kubectl grep pods "keyword" -l "key=value" $ kubectl grep pods "keyword" -l "key=value" -n "my-ns" $ kubectl grep pods "keyword" -l "key=value" -A # Supported Resources - [X] ConfigMaps - [X] DaemonSets - [X] Deployments - [X] HPAs - [X] Ingresses - [X] Jobs - [X] Nodes - [X] Pods - [X] Secrets - [X] StatefulSets # Installation Installation via [krew](https://krew.sigs.k8s.io/docs/user-guide/setup/install/) $ kubectl krew version # make sure you are running 0.4.0+ $ kubectl krew install grep $ kubectl krew upgrade Manual Installation $ export KUBECTL_GREP_VERSION=$(curl -s https://api.github.com/repos/guessi/kubectl-grep/releases/latest | jq -r .tag_name) $ curl -L -O https://github.com/guessi/kubectl-grep/releases/download/${KUBECTL_GREP_VERSION}/kubectl-grep-$(uname -s)-$(uname -m).tar.gz $ tar zxvf kubectl-grep-$(uname -s)-$(uname -m).tar.gz $ mv kubectl-grep /usr/local/bin $ chmod +x /usr/local/bin/kubectl-grep # Examples List all pods in default namespace, $ kubectl grep pods List all pods in all namespaces, $ kubectl grep pods -A List all pods with specific keyword, under specific namespace, $ kubectl grep pods -n star-lab flash # How to get developer build? $ go get -u github.com/guessi/kubectl-grep $ cd ${GOPATH}/src/github.com/guessi/kubectl-grep $ make all # FAQ How do I check the tool's version? $ kubectl grep version Any plan to support Kubernetes version before 1.10.0? sorry, it only support Kubernetes 1.10.0+ I'm now running Kubernetes 1.10.0, do I need to upgrade my cluster? nope, the only requirement is to upgrade your `kubectl` to 1.13.0+ Can I run Kubernetes 1.12.0 with kubectl 1.13.0? sure, no problem # Reference - [Kubectl Plugins](https://kubernetes.io/docs/tasks/extend-kubectl/kubectl-plugins/) # License [Apache-2.0](LICENSE)
