Types

type DynamicStack

type DynamicStack struct {
	// service discovery type
	ServiceDiscoveryType shared.ServiceDiscoveryType

	// number of virtual service
	VirtualServicesCount int

	// number of virtual nodes count
	VirtualNodesCount int

	// number of routes per virtual router

	// number of targets per route
	TargetsCountPerRoute int

	// number of backends per virtual node

}

A dynamic generated stack designed to test app mesh integration :D Suppose given configuration below:

5 VirtualServicesCount
10 VirtualNodesCount
2 RoutesCountPerVirtualRouter
2 TargetsCountPerRoute
4 BackendsCountPerVirtualNode

We will generate virtual service configuration & virtual node configuration follows: =======virtual services =========

vs1 -> /path1 -> vn1(50)
			  -> vn2(50)
	-> /path2 -> vn3(50)
			  -> vn4(50)
vs2 -> /path1 -> vn5(50)
			  -> vn6(50)
	-> /path2 -> vn7(50)
			  -> vn8(50)
vs3 -> /path1 -> vn9(50)
			  -> vn10(50)
	-> /path2 -> vn1(50)
			  -> vn2(50)
vs4 -> /path1 -> vn3(50)
			  -> vn4(50)
	-> /path2 -> vn5(50)
			  -> vn6(50)
vs5 -> /path1 -> vn7(50)
			  -> vn8(50)
	-> /path2 -> vn9(50)
			  -> vn10(50)

=======virtual nodes =========

vn1 -> vs1,vs2,vs3,vs4
vn2 -> vs5,vs1,vs2,vs3
vn3 -> vs4,vs5,vs1,vs2
...

then we validate each virtual node can access each virtual service at every path, and calculates the target distribution

func (*DynamicStack) Check

func (s *DynamicStack) Check(ctx context.Context, f *framework.Framework)

Check connectivity and routing works correctly

func (*DynamicStack) Cleanup

func (s *DynamicStack) Cleanup(ctx context.Context, f *framework.Framework)

expects the stack can be cleaned up from namespace successfully

func (*DynamicStack) Deploy

func (s *DynamicStack) Deploy(ctx context.Context, f *framework.Framework)

expects the stack can be deployed to namespace successfully
