What is Kubernetes config file?

The kubectl command-line tool uses kubeconfig files to find the information it needs to choose a cluster and communicate with the API server of a cluster. Note: A file that is used to configure access to clusters is called a kubeconfig file. This is a generic way of referring to configuration files.

Where is Kubernetes cluster data stored?

etcd. Consistent and highly-available key value store used as Kubernetes’ backing store for all cluster data. If your Kubernetes cluster uses etcd as its backing store, make sure you have a back up plan for those data. You can find in-depth information about etcd in the official documentation.

Why does Kubernetes use Yaml?

YAML Basics When defining a Kubernetes manifest, YAML gives you a number of advantages, including: Convenience: You’ll no longer have to add all of your parameters to the command line. Maintenance: YAML files can be added to source control, such as a Github repository so you can track changes.

How does kubectl connect to remote cluster?

Access from a node or pod in the cluster.

1. Run a pod, and then connect to a shell in it using kubectl exec. Connect to other nodes, pods, and services from that shell.
2. Some clusters may allow you to ssh to a node in the cluster. From there you may be able to access cluster services.

Static provisioning also goes against the mindset of Kubernetes in terms of how developers think about resources: CPU and memory are not allocated beforehand and bound to pods or containers. They are dynamically granted.

What do you need to know about Kubernetes API server?

kube-apiserver Synopsis. The Kubernetes API server validates and configures data for the api objects which include pods, services, replicationcontrollers, and others.

Configuration files should be stored in version control before being pushed to the cluster. This allows you to quickly roll back a configuration change if necessary. It also aids cluster re-creation and restoration. Write your configuration files using YAML rather than JSON.

What can you do with Kubernetes command line tool?

The kubectl command-line tool can be used to create, update, delete, and get API objects. Kubernetes also stores its serialized state (currently in etcd) in terms of the API resources. Kubernetes itself is decomposed into multiple components, which interact through its API.
