本文整理匯總了Golang中github.com/docker/swarmkit/node.Node類的典型用法代碼示例。如果您正苦於以下問題：Golang Node類的具體用法？Golang Node怎麽用？Golang Node使用的例子？那麽, 這裏精選的類代碼示例或許可以為您提供幫助。
在下文中一共展示了Node類的4個代碼示例，這些例子默認根據受歡迎程度排序。您可以為喜歡或者感覺有用的代碼點讚，您的評價將有助於係統推薦出更棒的Golang代碼示例。
示例1: handleReadyEvent
func (n *nodeRunner) handleReadyEvent(ctx context.Context, node *swarmnode.Node, ready chan struct{}) {
select {
case <-node.Ready():
n.mu.Lock()
n.err = nil
n.mu.Unlock()
close(ready)
case <-ctx.Done():
}
n.cluster.configEvent <- struct{}{}
}示例2: initClusterSpec
func initClusterSpec(node *swarmnode.Node, spec types.Spec) error {
ctx, _ := context.WithTimeout(context.Background(), 5*time.Second)

}
// In init, we take the initial default values from swarmkit, and merge
// any non nil or 0 value from spec to GRPC spec. This will leave the
// default value alone.
// Note that this is different from Update(), as in Update() we expect
// user to specify the complete spec of the cluster (as they already know
// the existing one and knows which field to update)
clusterSpec, err := convert.MergeSwarmSpecToGRPC(spec, cluster.Spec)
