Functions

func DatastoreDescribe 

func DatastoreDescribe(description string, datastores []apiconfig.DatastoreType, body func(InfraFactory)) bool

DatastoreDescribe is a replacement for ginkgo.Describe which invokes Describe multiple times for one or more different datastore drivers - passing in the function to retrieve the appropriate datastore infrastructure. This allows easy construction of end-to-end tests covering multiple different datastore drivers.

The *datastores* parameter is a slice of the DatastoreTypes to test.

func EnsureTLSCredentials 

func EnsureTLSCredentials()

func RemoveTLSCredentials 

func RemoveTLSCredentials()

func RunEtcd 

func RunEtcd() *containers.Container

func TearDownK8sInfra 

func TearDownK8sInfra(kds *K8sDatastoreInfra)

Types

type DatastoreInfra 

type DatastoreInfra interface {
	// GetDockerArgs returns a string slice of args to be passed to the docker
	// run command when starting Typha or Felix. It includes
	// CALICO_DATASTORE_TYPE, FELIX_DATASTORETYPE, an appropriate endpoint,
	// and any datastore specific needed ones.
	GetDockerArgs() []string
	// GetBadEndpointDockerArgs returns the same as GetDockerArgs but the
	// endpoint returned will have the incorrect port.
	GetBadEndpointDockerArgs() []string

	// GetCalicoClient will return a client.Interface configured to access
	// the datastore.
	GetCalicoClient() client.Interface
	// SetExpectedIPIPTunnelAddr will set the Felix object's
	// ExpectedIPIPTunnelAddr field, if we expect Felix to see that field being
	// set after it has started up for the first time.
	SetExpectedIPIPTunnelAddr(felix *Felix, idx int, needBGP bool)
	// AddNode will take the appropriate steps to add a node to the datastore.
	// From the passed in felix the Hostname and IPv4 address will be pulled
	// and added to the Node appropriately.
	// The passed in idx will be used to setup the Tunnel or PodCIDR (from
	// which the tunnel is created). needBGP is used (only in etcd) to
	// add a NodeBGPSpec if true or otherwise not.
	AddNode(felix *Felix, idx int, needBGP bool)
	// AddWorkload will take the appropriate steps to create a workload in the
	// datastore with the passed in wep values. If this succeeds then the
	// *api.WorkloadEndpoint will be returned, otherwise an error will be
	// returned.
	AddWorkload(wep *api.WorkloadEndpoint) (*api.WorkloadEndpoint, error)
	// AddDefaultAllow will ensure that the datastore is configured so that
	// the default profile/namespace will allow traffic.
	AddDefaultAllow() error
	// AddDefaultDeny will ensure that the datastore is configured so that
	// the default profile/namespace will deny ingress traffic.
	AddDefaultDeny() error
	// AddAllowToDatastore adds a policy to allow endpoints that match the given
	// selector to reach the datastore.
	AddAllowToDatastore(selector string) error

	// DumpErrorData prints out extra information that may help when an error
	// occurs.
	DumpErrorData()

	// Stop cleans up anything necessary in preparation for the end of the test.
	Stop()
}

DatastoreInfra is an interface that is to be used to abstract away the datastore being used and the functions that are datastore specific

func StartNNodeEtcdTopology 

func StartNNodeEtcdTopology(n int, opts TopologyOptions) (felixes []*Felix, etcd *containers.Container, client client.Interface)

StartNNodeEtcdTopology starts an etcd container and a set of Felix hosts. If n > 1, sets up IPIP, otherwise this is skipped.

  • Configures an IPAM pool for 10.65.0.0/16 (so that Felix programs the all-IPAM blocks IP set) but (for simplicity) we don't actually use IPAM to assign IPs.
  • Configures routes between the hosts, giving each host 10.65.x.0/24, where x is the index in the returned array. When creating workloads, use IPs from the relevant block.
  • Configures the Tunnel IP for each host as 10.65.x.1.

func StartNNodeTopology 

func StartNNodeTopology(n int, opts TopologyOptions, infra DatastoreInfra) (felixes []*Felix, client client.Interface)
