|
|
This page outlines steps to find out what [container runtime](/docs/setup/production-environment/container-runtimes/)
|
|
the nodes in your cluster use.
|
|
|
|
Depending on the way you run your cluster, the container runtime for the nodes may
|
|
have been pre-configured or you need to configure it. If you're using a managed
|
|
Kubernetes service, there might be vendor-specific ways to check what container runtime is
|
|
configured for the nodes. The method described on this page should work whenever
|
|
the execution of `kubectl` is allowed.
|
|
|
|
## {{% heading "prerequisites" %}}
|
|
|
|
Install and configure `kubectl`. See [Install Tools](/docs/tasks/tools/#kubectl) section for details.
|
|
|
|
## Find out the container runtime used on a Node
|
|
|
|
Use `kubectl` to fetch and show node information:
|
|
|
|
```shell
|
|
kubectl get nodes -o wide
|
|
```
|
|
|
|
The output is similar to the following. The column `CONTAINER-RUNTIME` outputs
|
|
the runtime and its version.
