CNTR-2: Container network connectivity tests

Tests within this directory ensure that a container deployed on a network device is able to connect to external services via gRPC.

CNTR-2.1: Connect to container from external client.

Deploy a container to a DUT that is listening on [::]:60061. Validate that the test can connect to tcp/60061 via gRPC and receive a response on a simple "dummy" service.

CNTR-2.2: Connect to locally running service.

For a DUT configured with gNMI running on tcp/9339 (IANA standard), and gRIBI running on tcp/9340 (IANA standard), the test should:

• Instruct the container to make a gRPC Dial call to the running gNMI instance, with a specified timeout. The test succeeds if the connection succeeds within the timeout, otherwise it fails.
• Instruct the container to make a gRPC Dial call to the running gRIBI instance with the same pass/fail logic.

CNTR-2.3: Connect to a remote node.

Deploy two DUTs running in the following configuration:

  [  c1   ]                 [  c2   ]
  ---------                 --------
  [ DUT 1 ] ---- port1 ---- [ DUT 2 ]

where c1 is an instance of the "listener" container image, and c2 is an instance of the "dialer" image.

The test should: * ensure that c1 is listening on [::]:60071 running a gRPC service. * use gNMI to configure and/or discover the link local addresses configured on DUT1 port 1 and DUT2 port1. * instruct c2 to make a dial call and isue a simple RPC to the address configured by c1. If the dial call succeeds within a specified timeout, the test passes, otherwise it fails.

CNTR-2.4: Connect to another container on a local node

Deploy a single DUT with two containers C1 and C2 running on them. C1 should listen on a gRPC service on tcp/[::]:60061 and C2 should listen on a gRPC service on tcp/[::]60062.

• Instruct C1 to make a gRPC dial call to C2's listen port with a specified timeout, ensure that an RPC response is received.
• Instruct C2 to make a gRPC dial call to C2's listen port with a specified timeout, ensure that an RPC response is received.
