Command recall

Command recall is the one exercise that runs in the browser. It asks for the command behind a task, such as "create deployment web from nginx with 3 replicas", and you produce it from memory. It trains the imperative commands that save minutes in an exam. It is not a drill: nothing runs, no cluster is involved, and nothing is graded against a live system.

Open Recall ↗ from the app's header or from the Command recall card on My practice. You need to be signed in.

What it covers

There are 257 tasks in 22 sections, grouped under three headings:

• kubectl. Pods, workloads, services and ingress, ConfigMaps and secrets, namespaces and policy, RBAC, changing live objects, rollouts, nodes, delete, inspect and debug, scaffolding kinds that have no generator, and output shaping.
• Cluster tools. Helm, Kustomize, kubeadm with etcd and the kubelet, and crictl.
• Track tools. Istio for ICA, security tooling for CKS, Cilium and network debugging for CKNE, Argo CD and Kyverno for CNPE, and Linux for LFCS.

Pick a section, or work through all of them in order.

Two modes

Type it. Type the command and press Enter. The check happens in your browser by comparing your command with the accepted answers. It accepts what the tool itself treats as the same command:

• k for kubectl, a leading sudo, and a leading ETCDCTL_API=3
• flags in any order, and --flag value or --flag=value
• each tool's own short flags, such as -n, -f and -A
• kubectl short names and both object forms: deploy, svc, deploy/web or deploy web
• comma lists in any order, such as --verb=get,list,watch

The order of plain words still matters, because cp a b is not cp b a. A wrong answer names the flags that are missing or not needed, without their values, so you can try again. Several tasks accept more than one answer, and the answer panel lists them.

Flashcards. Read the task, recall the command, show it, then mark it got or missed yourself.

What counts

A typed answer that is right before you look counts as recalled. Showing the answer first counts as missed, even if you then type it correctly. Each section shows how many tasks you have recalled.

Progress is kept in this browser only. It does not sync to your account or to another device, and clearing site data resets it. Reset clears a section or everything.

Command recall records no reps. It does not appear in Reports, it does not move readiness, and it cannot produce a cold pass. Those come only from drills and mock exams in the CLI. Treat recall as the warm-up and the drill as the proof.

Accuracy

Values in tasks, such as chart versions and host names, are placeholders. Tool flags change between releases, so when a command disagrees with --help on your machine, trust --help and tell hello@kubefit.com.

Timed terminal rounds

Use AMRAP for a timed, one-shot version in your terminal: kubefit amrap 5m. AMRAP saves its own reports to your account; browser Recall progress remains local.
