原作者: [db:作者] 来自: [db:来源] 收藏 邀请

本文整理汇总了Golang中github.com/openshift/origin/pkg/security/uid.ParseBlock函数的典型用法代码示例。如果您正苦于以下问题:Golang ParseBlock函数的具体用法?Golang ParseBlock怎么用?Golang ParseBlock使用的例子?那么恭喜您, 这里精选的函数代码示例或许可以为您提供帮助。



在下文中一共展示了ParseBlock函数的3个代码示例,这些例子默认根据受欢迎程度排序。您可以为喜欢或者感觉有用的代码点赞,您的评价将有助于我们的系统推荐出更棒的Golang代码示例。

示例1: RunOnce

// RunOnce verifies the state of allocations and returns an error if an unrecoverable problem occurs.
func (c *Repair) RunOnce() error {
	// TODO: (per smarterclayton) if Get() or List() is a weak consistency read,
	// or if they are executed against different leaders,
	// the ordering guarantee required to ensure no item is allocated twice is violated.
	// List must return a ResourceVersion higher than the etcd index Get,
	// and the release code must not release items that have allocated but not yet been created
	// See #8295

	latest, err := c.alloc.Get()
	if err != nil {
		return fmt.Errorf("unable to refresh the security allocation UID blocks: %v", err)
	}

	list, err := c.client.List(kapi.ListOptions{})
	if err != nil {
		return fmt.Errorf("unable to refresh the security allocation UID blocks: %v", err)
	}

	uids := uidallocator.NewInMemory(c.uidRange)

	for _, ns := range list.Items {
		value, ok := ns.Annotations[security.UIDRangeAnnotation]
		if !ok {
			continue
		}
		block, err := uid.ParseBlock(value)
		if err != nil {
			continue
		}
		switch err := uids.Allocate(block); err {
		case nil:
		case uidallocator.ErrNotInRange, uidallocator.ErrAllocated:
			continue
		case uidallocator.ErrFull:
			// TODO: send event
			return fmt.Errorf("the UID range %s is full; you must widen the range in order to allocate more UIDs", c.uidRange)
		default:
			return fmt.Errorf("unable to allocate UID block %s for namespace %s due to an unknown error, exiting: %v", block, ns.Name, err)
		}
	}

	err = uids.Snapshot(latest)
	if err != nil {
		return fmt.Errorf("unable to persist the updated namespace UID allocations: %v", err)
	}

	if err := c.alloc.CreateOrUpdate(latest); err != nil {
		return fmt.Errorf("unable to persist the updated namespace UID allocations: %v", err)
	}
	return nil
}

示例2: parseSupplementalGroupAnnotation

// parseSupplementalGroupAnnotation parses the group annotation into blocks.
func parseSupplementalGroupAnnotation(groups string) ([]uid.Block, error) {
	blocks := []uid.Block{}
	segments := strings.Split(groups, ",")
	for _, segment := range segments {
		block, err := uid.ParseBlock(segment)
		if err != nil {
			return nil, err
		}
		blocks = append(blocks, block)
	}
	if len(blocks) == 0 {
		return nil, fmt.Errorf("no blocks parsed from annotation %s", groups)
	}
	return blocks, nil
}

示例3: getPreallocatedUIDRange

// getPreallocatedUIDRange retrieves the annotated value from the service account, splits it to make
// the min/max and formats the data into the necessary types for the strategy options.
func getPreallocatedUIDRange(ns *kapi.Namespace) (*int64, *int64, error) {
	annotationVal, ok := ns.Annotations[allocator.UIDRangeAnnotation]
	if !ok {
		return nil, nil, fmt.Errorf("unable to find annotation %s", allocator.UIDRangeAnnotation)
	}
	if len(annotationVal) == 0 {
		return nil, nil, fmt.Errorf("found annotation %s but it was empty", allocator.UIDRangeAnnotation)
	}
	uidBlock, err := uid.ParseBlock(annotationVal)
	if err != nil {
		return nil, nil, err
	}

	var min int64 = int64(uidBlock.Start)
	var max int64 = int64(uidBlock.End)
	glog.V(4).Infof("got preallocated values for min: %d, max: %d for uid range in namespace %s", min, max, ns.Name)
	return &min, &max, nil
}
