This command prints the version of kubeadm. Print the version of kubeadm Synopsis Print the version of kubeadm kubeadm version [flags] Options -h, --help help for version -o, --output string Output format; available options are 'yaml', 'json' and 'short' Options inherited from parent commands --rootfs string The path to the 'real' host root filesystem. This will cause kubeadm to chroot into the provided path.

Package v1 is the v1 version of the API. Resource Types AdmissionConfiguration EncryptionConfiguration AdmissionConfiguration AdmissionConfiguration provides versioned configuration for admission controllers. FieldDescription apiVersionstringapiserver.config.k8s.io/v1 kindstringAdmissionConfiguration plugins []AdmissionPluginConfiguration Plugins allows specifying a configuration per admission control plugin. EncryptionConfiguration EncryptionConfiguration stores the complete configuration for encryption providers. It also allows the use of wildcards to specify the resources that should be encrypted. Use '*.<group>' to encrypt all resources within a group or '*.*' to encrypt all resources.

Resource Types CredentialProviderRequest CredentialProviderResponse CredentialProviderRequest CredentialProviderRequest includes the image that the kubelet requires authentication for. Kubelet will pass this request object to the plugin via stdin. In general, plugins should prefer responding with the same apiVersion they were sent. FieldDescription apiVersionstringcredentialprovider.kubelet.k8s.io/v1 kindstringCredentialProviderRequest image [Required] string image is the container image that is being pulled as part of the credential provider plugin request. Plugins may optionally parse the image to extract any information required to fetch credentials.

Resource Types CredentialProviderConfig CredentialProviderConfig CredentialProviderConfig is the configuration containing information about each exec credential provider. Kubelet reads this configuration from disk and enables each provider as specified by the CredentialProvider type. FieldDescription apiVersionstringkubelet.config.k8s.io/v1alpha1 kindstringCredentialProviderConfig providers [Required] []CredentialProvider providers is a list of credential provider plugins that will be enabled by the kubelet. Multiple providers may match against a single image, in which case credentials from all providers will be returned to the kubelet.

There are lots of ways to contribute to Kubernetes. You can work on designs for new features, you can document the code we already have, you can write for our blog. There's more: you can implement those new features or fix bugs. You can help people join our contributor community, or support existing contributors. With all these different ways to make a difference to the project, we - Kubernetes - have made a dedicated website: https://k8s.

Anyone can review a documentation pull request. Visit the pull requests section in the Kubernetes website repository to see open pull requests. Reviewing documentation pull requests is a great way to introduce yourself to the Kubernetes community. It helps you learn the code base and build trust with other contributors. Before reviewing, it's a good idea to: Read the content guide and style guide so you can leave informed comments.

Bootstrapping clusters with kubeadm Installing kubeadm Troubleshooting kubeadm Creating a cluster with kubeadm Custom...

Using kubeadm, you can create a minimum viable Kubernetes cluster that conforms to best practices. In fact, you can use kubeadm to set up a cluster that will pass the Kubernetes Conformance tests. kubeadm also supports other cluster lifecycle functions, such as bootstrap tokens and cluster upgrades. The kubeadm tool is good if you need: A simple way for you to try out Kubernetes, possibly for the first time. A way for existing users to automate setting up a cluster and test their application.

In robotics and automation, a control loop is a non-terminating loop that regulates the state of a system. Here is one example of a control loop: a thermostat in a room. When you set the temperature, that's telling the thermostat about your desired state. The actual room temperature is the current state. The thermostat acts to bring the current state closer to the desired state, by turning equipment on or off.
