Actions
describe
Show details of a specific resource or group of resources.
Print a detailed description of the selected resources, including related resources such as events or controllers. You may select a single object by name, all objects of that type, provide a name prefix, or label selector. For example:
$ kubectl describe TYPE NAME_PREFIX
will first check for an exact match on TYPE and NAME PREFIX. If no such resource exists, it will output details for every resource that has a name prefixed with NAME PREFIX.
get
Display one or many resources.
Prints a table of the most important information about the specified resources. You can filter the list using a label selector and the --selector flag. If the desired resource type is namespaced you will only see results in your current namespace unless you pass --all-namespaces.
Uninitialized objects are not shown unless --include-uninitialized is passed.
By specifying the output as 'template' and providing a Go template as the value of the --template flag, you can filter the attributes of the fetched resources.
run
The run command creates a new deployment. This performed a few things.
- Searched for a suitable node where an instance of the application could be run.
- Scheduled the application to run on that Node.
- Configured the cluster to reschedule the instance on a new Node when needed.
proxy
Creates a proxy server or application-level gateway between localhost and the Kubernetes API server. It also allows serving static content over the specified HTTP path. All incoming data enters through one port and gets forwarded to the remote Kubernetes API server port, except for the path matching the static content path.
