Uses the Rancher CLI (`rancher`) to log into Rancher Server, select a project context, and run cluster/project operations including passthrough `kubectl`. Apply when the user manages Rancher projects, clusters, or workloads through Rancher rather than a raw kubeconfig alone.

We split this skill into the rules it gives an agent

3 rules. About 0 are common, 1 is distinctive, and 2 are very specific to this project.

  • ≈0

    Common · estimate

    Many files like this have a rule of this kind.

  • ≈1

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 2

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Very specific:

    Run rancher kubectl … to execute kubectl against the cluster associated with the current Rancher context.

    line 16
  2. Very specific:

    After login, select a project with rancher context switch before most operations.

    line 23
  3. Distinctive:

    Treat API bearer tokens like passwords.

    line 53

≈ “Common” is an estimate: at least 1 in 5 of the 308,232 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Rancher CLI (rancher)

When to use

  • Authenticate to a Rancher Server and work in terms of Rancher projects and clusters.
  • Switch context to the project/cluster scope before running resource commands.
  • Run rancher kubectl … to execute kubectl against the cluster associated with the current Rancher context.
  • Inspect Rancher or Kubernetes resources via inspect, list workloads with ps, or use subcommands such as clusters, projects, namespaces, nodes, machines.

Prerequisites

  • rancher binary installed (often downloaded from the Rancher UI CLI Downloads or rancher/cli releases). Documentation: Rancher CLI.
  • Rancher Server URL and a Bearer API token (API keys).
  • After login, select a project with rancher context switch before most operations; config is stored (e.g. ~/.ranchcli2.json per upstream docs).

Patterns

  • Help: rancher --help, rancher <cmd> --help.
  • Login: rancher login https://<SERVER_URL> --token <BEARER_TOKEN>. Self-signed certs may prompt to continue.
  • Context: rancher context switch — pick the Rancher project (cluster + project) to target.
  • kubectl: rancher kubectl get pods (and other kubectl subcommands) once context is valid.
  • Inspect: rancher inspect for Kubernetes or Rancher resources (see command help for options and resource IDs).

Core commands (orienting)

AreaExamples
Sessionrancher login, rancher token (kubeconfig token; see --help)
Contextrancher context switch
Clusters / projectsrancher clusters, rancher projects (see --help for subcommands)
Workloadsrancher ps, rancher namespaces
kubectlrancher kubectl get pods, rancher kubectl describe …
Nodes / SSHrancher nodes, rancher ssh (see --help)
Otherrancher inspect, rancher settings, rancher wait, rancher up

Exact subcommands and flags depend on the CLI version; prefer rancher <cmd> --help.

Limitations

  • The Rancher CLI cannot install Rancher dashboard apps or feature charts via Helm in the way the UI/charts flow does — see the official docs.

Safety

  • Treat API bearer tokens like passwords; do not log or commit them.
  • Operations on clusters, nodes, or workloads can be destructive — align with the user’s intent and environment (prod vs non-prod).

References

  • Official documentation: Rancher CLI
  • Local help: rancher --help, rancher <cmd> --help (authoritative for your installed rancher version)
