Examples with V1PodList io.kubernetes.client.openapi.models.V1PodList used on opensource projects

Example 16 with V1PodList

use of io.kubernetes.client.openapi.models.V1PodList in project java by kubernetes-client.

the class CoreV1Api method listPodForAllNamespacesAsync.

/**
 * (asynchronously) list or watch objects of kind Pod
 *
 * @param allowWatchBookmarks allowWatchBookmarks requests watch events with type
 *     \"BOOKMARK\". Servers that do not implement bookmarks may ignore this flag and
 *     bookmarks are sent at the server's discretion. Clients should not assume bookmarks are
 *     returned at any specific interval, nor may they assume the server will send any BOOKMARK
 *     event during a session. If this is not a watch, this field is ignored. (optional)
 * @param _continue The continue option should be set when retrieving more results from the
 *     server. Since this value is server defined, clients may only use the continue value from a
 *     previous query result with identical query parameters (except for the value of continue)
 *     and the server may reject a continue value it does not recognize. If the specified continue
 *     value is no longer valid whether due to expiration (generally five to fifteen minutes) or a
 *     configuration change on the server, the server will respond with a 410 ResourceExpired
 *     error together with a continue token. If the client needs a consistent list, it must
 *     restart their list without the continue field. Otherwise, the client may send another list
 *     request with the token received with the 410 error, the server will respond with a list
 *     starting from the next key, but from the latest snapshot, which is inconsistent from the
 *     previous list results - objects that are created, modified, or deleted after the first list
 *     request will be included in the response, as long as their keys are after the \"next
 *     key\". This field is not supported when watch is true. Clients may start a watch from
 *     the last resourceVersion value returned by the server and not miss any modifications.
 *     (optional)
 * @param fieldSelector A selector to restrict the list of returned objects by their fields.
 *     Defaults to everything. (optional)
 * @param labelSelector A selector to restrict the list of returned objects by their labels.
 *     Defaults to everything. (optional)
 * @param limit limit is a maximum number of responses to return for a list call. If more items
 *     exist, the server will set the `continue` field on the list metadata to a value
 *     that can be used with the same initial query to retrieve the next set of results. Setting a
 *     limit may return fewer than the requested amount of items (up to zero items) in the event
 *     all requested objects are filtered out and clients should only use the presence of the
 *     continue field to determine whether more results are available. Servers may choose not to
 *     support the limit argument and will return all of the available results. If limit is
 *     specified and the continue field is empty, clients may assume that no more results are
 *     available. This field is not supported if watch is true. The server guarantees that the
 *     objects returned when using continue will be identical to issuing a single list call
 *     without a limit - that is, no objects created, modified, or deleted after the first request
 *     is issued will be included in any subsequent continued requests. This is sometimes referred
 *     to as a consistent snapshot, and ensures that a client that is using limit to receive
 *     smaller chunks of a very large result can ensure they see all possible objects. If objects
 *     are updated during a chunked list the version of the object that was present at the time
 *     the first list result was calculated is returned. (optional)
 * @param pretty If 'true', then the output is pretty printed. (optional)
 * @param resourceVersion resourceVersion sets a constraint on what resource versions a request
 *     may be served from. See
 *     https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details.
 *     Defaults to unset (optional)
 * @param resourceVersionMatch resourceVersionMatch determines how resourceVersion is applied to
 *     list calls. It is highly recommended that resourceVersionMatch be set for list calls where
 *     resourceVersion is set See
 *     https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details.
 *     Defaults to unset (optional)
 * @param timeoutSeconds Timeout for the list/watch call. This limits the duration of the call,
 *     regardless of any activity or inactivity. (optional)
 * @param watch Watch for changes to the described resources and return them as a stream of add,
 *     update, and remove notifications. Specify resourceVersion. (optional)
 * @param _callback The callback to be executed when the API call finishes
 * @return The request call
 * @throws ApiException If fail to process the API call, e.g. serializing the request body object
 * @http.response.details
 *     <table summary="Response Details" border="1">
 * <tr><td> Status Code </td><td> Description </td><td> Response Headers </td></tr>
 * <tr><td> 200 </td><td> OK </td><td>  -  </td></tr>
 * <tr><td> 401 </td><td> Unauthorized </td><td>  -  </td></tr>
