Download a zip that contains the binary from [releases](https://github.com/emirozer/kubectl-doctor/releases) that is compatible with your os/arch 11 | 2.

Add it to your `PATH` 13 | 14 | ## Usage 15 | When the plugin binary is found from `PATH` you can just execute it through `kubectl` CLI 16 | ```shell 17 | kubectl doctor 18 | ``` 19 | 20 | ## Current list of anomaly checks 21 | 22 | * core component health (etcd cluster members, scheduler, controller-manager) 23 | * orphan endpoints (endpoints with no ipv4 attached) 24 | * persistent-volume available & unclaimed 25 | * persistent-volume-claim in lost state 26 | * k8s nodes that are not in ready state 27 | * orphan replicasets (desired number of replicas are bigger than 0 but the available replicas are 0) 28 | * leftover replicasets (desired number of replicas and the available # of replicas are 0) 29 | * orphan deployments (desired number of replicas are bigger than 0 but the available replicas are 0) 30 | * leftover deployments (desired number of replicas and the available # of replicas are 0) 31 | * leftover cronjobs (last active date is more than 30 days) 32 | -------------------------------------------------------------------------------- /cmd/kubectl-doctor.go: -------------------------------------------------------------------------------- 1 | package main 2 | 3 | import ( 4 | "os" 5 | 6 | "github.com/emirozer/kubectl-doctor/pkg/plugin" 7 | "github.com/spf13/pflag" 8 | _ "k8s.io/client-go/plugin/pkg/client/auth" 9 | ) 10 | 11 | func main() { 12 | flags := pflag.NewFlagSet("kubectl-doctor", pflag.ExitOnError) 13 | pflag.CommandLine = flags 14 | 15 | // bypass to DoctorCmd 16 | cmd := plugin.NewDoctorCmd() 17 | if err := cmd.Execute(); err != nil { 18 | os.Exit(1) 19 | } 20 | } 21 | -------------------------------------------------------------------------------- /docs/example.svg: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | 5 | 6 | 7 | 82 | 103 | 104 | 105 | kubectl-doctor|master⚡ ⇒ kubectl-doctor|master⚡ ⇒ . kubectl-doctor|master⚡ ⇒ ./ kubectl-doctor|master⚡ ⇒ ./b kubectl-doctor|master⚡ ⇒ ./bi kubectl-doctor|master⚡ ⇒ ./bin/ kubectl-doctor|master⚡ ⇒ ./bin/kubectl-doctor kubectl-doctor|master⚡ ⇒ ./bin/kubectl-doctor kubectl-doctor|master⚡ ⇒ ./bin/kubectl-doctor WARN[0000] KUBECONFIG env var not found falling back to auto discovery!
