It's a plugin for kubectl that gives you a UNIX find-like experience.
Find resource based on
- name regex
- age
- labels
- status
- node name (for pods only)
- restarts (for pods only)
- image name (for pods only)
- jq filter - custom condition
and then print, patch or delete any.
kubectl fd [resource type | pods] [flags] Flags: -r, --name string Regular expression to match resource names against; if not specified, all resources of the specified type will be returned. -n, --namespace string If present, the namespace scope for this CLI request -A, --all-namespaces Search in all namespaces; if not specified, only the current namespace will be searched. --status string Filter pods by their status (phase); e.g. 'Running', 'Pending', 'Succeeded', 'Failed', 'Unknown'. --image string Regular expression to match container images against. -j, --jq string jq expression to filter resources; Uses gojq library for evaluation. --restarted Find pods that have been restarted at least once. -l, --selector string Label selector to filter resources by labels. --max-age string Filter resources by maximum age; e.g. '2d' for 2 days, '3h' for 3 hours, etc. --min-age string Filter resources by minimum age; e.g. '2d' for 2 days, '3h' for 3 hours, etc. --node string Filter pods by node name regex; Uses pod.Spec.NodeName or pod.Status.NominatedNodeName if the former is empty. -L, --labels strings Comma-separated list of labels to show. -N, --node-labels strings Comma-separated list of node labels to show. --natural-sort Sort resource names in natural order. -h, --help help for kubectl find -p, --patch string Patch all found resources with the specified JSON patch. -e, --exec string Execute a command on all found pods. --delete Delete all matched resources. -f, --force Skip confirmation prompt before performing actions on resources.Using krew
krew install fdDownload latest release for your platform/os and save it under $PATH as kubectl-fd
Based on gojq implementation of jq. Check resource structure on kubespec.dev.
