Running the Antrea end-to-end tests

Creating the test Kubernetes cluster

The tests must be run on an actual Kubernetes cluster. At the moment, we require the cluster to be created using Vagrant and the provided Vagrantfile, which you can do by following the instructions below.

Creating the test Kubernetes cluster with Vagrant

We use Vagrant to provision two Virtual Machines (one Kubernetes control-plane Node and one worker Node). The required software is installed on each machine with Ansible. By default the Vagrantfile uses VirtualBox but you should be able to edit the file to use your favorite Vagrant provider.

Dependencies

We require the following to be installed on your host machine:

  • vagrant (>= 2.0.0)
  • ansible (>= 2.4.0)
  • virtualbox (See supported versions here).
Ubuntu 18.04 (or later)

You can install all dependencies with sudo apt install vagrant ansible virtualbox.

Mac OS

You can install all the dependencies with brew:

  • brew install --cask virtualbox
  • brew install --cask vagrant
  • brew install ansible

If an action is required on your part, brew will let you know in its log messages.

Managing the cluster

Use the following Bash scripts to manage the Kubernetes Nodes with Vagrant:

  • ./infra/vagrant/provision.sh: create the required VMs and provision them
  • ./infra/vagrant/push_antrea.sh: load Antrea Docker image to each Node, along with the Antrea deployment YAML
  • ./infra/vagrant/suspend.sh: suspend all Node VMs
  • ./infra/vagrant/resume.sh: resume all Node VMs
  • ./infra/vagrant/destroy.sh: destoy all Node VMs, you will need to run provision.sh again to create a new cluster

Note that ./infra/vagrant/provision.sh can take a while to complete but it only needs to be run once.

IPv6 cluster

To test Antrea IPv6 support, an IPv6-only cluster can be created, by provisioning a private IPv6 network to connect Kubernetes Nodes, instead of a private IPv4 network. You simply need to invoke ./infra/vagrant/provision.sh with --ip-family v6. This option can be used even if the host machine does not support IPv6 itself. Note however that the Nodes do not have public IPv6 connectivity; they can still connect to the Internet using IPv4, which means that Docker images can be pulled without issue. Similarly, Pods (which only support IPv6) cannot connect to the Internet. To avoid issues when running Kubernetes conformance tests, we configure a proxy on the control-plane Node for all DNS traffic. While CoreDNS will reply to cluster local DNS queries directly, all other queries will be forwarded to the proxy over IPv6, and the proxy will then forward them to the default resolver for the Node (this time over IPv4). This means that all DNS queries from the Pods should succeed, even though the returned public IP addresses (IPv4 and / or IPv6) are not accessible.

You may need more recent versions of the dependencies (virtualbox, vagrant, ansible) than the ones listed above when creating an IPv6 cluster. The following versions were tested successfully:

  • vagrant 2.2.14
  • ansible 2.9.18
  • virtualbox 5.2
Debugging

You can SSH into any of the Node VMs using vagrant ssh [Node name] (must be run from the infra/vagrant directory. The control-plane Node is named k8s-node-control-plane and the worker Nodes are named k8s-node-worker-<N> (for a single worker Node, the name is k8s-node-worker-1. kubectl is installed on all the Nodes.

The kubeconfig file for the cluster can also be found locally on your machine at ./infra/vagrant/playbook/kube/config. If you install kubectl locally and set the KUBECONFIG environment variable to the absolute path of this kubeconfig file, you can run commands against your test cluster created with Vagrant. For example:

cd <directory containing this README file>
export KUBECONFIG=`pwd`/infra/vagrant/playbook/kube/config
kubectl cluster-info
Known issues
The IP address configured for the host-only network is not within the allowed ranges

With recent versions of VirtualBox (> 6.1.26), you may see the following error when running ./infra/vagrant/provision.sh:

The IP address configured for the host-only network is not within the
allowed ranges. Please update the address used to be within the allowed
ranges and run the command again.

  Address: 192.168.77.100
  Ranges: 192.168.56.0/21

Valid ranges can be modified in the /etc/vbox/networks.conf file. For
more information including valid format see:

  https://www.virtualbox.org/manual/ch06.html#network_hostonly

To workaround this issue, you can either:

  • downgrade your VirtualBox version to 6.1.26
  • create a /etc/vbox/networks.conf file with the following contents:
* 192.168.77.0/24

Running the tests

Make sure that your cluster was provisioned and that the Antrea build artifacts were pushed to all the Nodes. You can then run the tests from the top-level directory with go test -v -timeout=30m antrea.io/antrea/test/e2e (the -v enables verbose output).

Running the tests with vagrant

If you are running the test for the first time and are using the scripts we provide under infra/vagrant to provision your Kubernetes cluster, you will therefore need the following steps:

  1. ./infra/vagrant/provision.sh
  2. make
  3. ./infra/vagrant/push_antrea.sh
  4. go test -v -timeout=30m antrea.io/antrea/test/e2e

If you need to test an updated version of Antrea, just run ./infra/vagrant/push_antrea.sh and then run the tests again.

Running the tests with remote (existing K8s cluster)

If you already have a K8s cluster, these steps should be followed to run the e2e tests.

First, you should provide the ssh information for each Node in the cluster. Here is an example:

Host <Control-Plane-Node>
    HostName <Control-Plane-IP>
    Port 22
    user ubuntu
    IdentityFile /home/ubuntu/.ssh/id_rsa
Host <Worker-Node>
    HostName <Worker-Node-IP>
    Port 22
    user ubuntu
    IdentityFile /home/ubuntu/.ssh/id_rsa

Make sure the Host entry for each Node matches the K8s Node name. The Port is the port used by the ssh service on the Node.

Besides, you should add the public key to authorized_keys of each Node and set PubkeyAuthentication of ssh service to yes.

Second, the kubeconfig of the cluster should be copied to the right location, e.g. $HOME/.kube/config or the path specified by -remote.kubeconfig.

Third, the antrea.yml (and antrea-windows.yml if the cluster has Windows Nodes) should be put under the $HOME directory of the control-plane Node.

Now you can start e2e tests using the command below:

go test -v antrea.io/antrea/test/e2e -provider=remote

You can specify ssh and kubeconfig locations with -remote.sshconfig and -remote.kubeconfig. The default location of -remote.sshconfig is $HOME/.ssh/config and the default location of -remote.kubeconfig is $HOME/.kube/config.

Running the e2e tests on a Kind cluster

The simplest way is to run the following command:

./ci/kind/test-e2e-kind.sh [options]

It will set up a two worker Node Kind cluster to run the e2e tests, and destroy the cluster after the tests stop (succeed or fail). kubectl needs to be present in your PATH to set up the test cluster. For more information on the usage of this script and the options, run:

./ci/kind/test-e2e-kind.sh --help

You can also run the e2e tests with an existing Kind cluster. Refer to this document for instructions on how to create a Kind cluster and use Antrea as the CNI. You need at least one control-plane Node and one worker Node. Before running the Go e2e tests, you will also need to copy the Antrea manifest to the control-plane Docker container:

./hack/generate-manifest.sh | docker exec -i kind-control-plane dd of=/root/antrea.yml
go test -timeout=75 -v antrea.io/antrea/test/e2e -provider=kind

The default timeout of go test is 10 minutes. If you encounter any timeout issue during e2e, you can try to increase timeout first. Some cases take more than 10 minutes. eg: go test -v -timeout=20m antrea.io/antrea/test/e2e -run=TestAntreaPolicy -provider=kind.

generate-manifest.sh supports generating the Antrea manifest with different Antrea configurations. Run ./hack/generate-manifest.sh --help to see the supported config options.

As part of code development, if you want to run the tests with local changes, then make the code changes on the local repo and build the image. You can load the new image into the kind cluster using the command below:

kind load docker-image antrea/antrea-ubuntu:latest --name <kind_cluster_name>

By default, if a test case fails, we write some useful debug information to a temporary directory on disk. This information includes the detailed description (obtained with kubectl describe) and the logs (obtained with kubectl logs) of each Antrea Pod at the time the test case exited. When running the tests in verbose mode (i.e. with -v), the test logs will tell you the location of that temporary directory. You may also choose your own directory using --logs-export-dir. For example:

mkdir antrea-test-logs
go test -count=1 -v -run=TestDeletePod antrea.io/antrea/test/e2e --logs-export-dir `pwd`/antrea-test-logs

If the user provides a log directory which was used for a previous run, existing contents (subdirectories for each test case) will be overridden. By default the description and logs for Antrea Pods are only written to disk if a test fails. You can choose to dump this information unconditionally with --logs-export-on-success.

Testing the Prometheus Integration

The Prometheus integration tests can be run as part of the e2e tests when enabled explicitly.

  • To load Antrea into the cluster with Prometheus enabled, use: ./infra/vagrant/push_antrea.sh --prometheus
  • To run the Prometheus tests within the e2e suite, use: go test -v antrea.io/antrea/test/e2e --prometheus

Running the performance test

To run all benchmarks, without the standard e2e tests:

go test -v -timeout=30m -run=XXX -bench=. \
    antrea.io/antrea/test/e2e \
    -perf.http.concurrency=16

The above command uses -run=XXX to deselect all Test* tests and uses -bench=. to select all Benchmark* tests. Since performance tests take a while to complete, you need to extend the timeout duration -timeout from the default 10m to a longer one like 30m.

If you would like to run the performance tests in a different scale, you could run:

go test -v -timeout=30m -run=XXX -bench=BenchmarkCustomize \
    antrea.io/antrea/test/e2e \
    -perf.http.requests=5000 \
    -perf.http.policy_rules=1000 \
    -perf.http.concurrency=16

All flags of performance tests includes:

  • performance.http.concurrency (int): Number of allowed concurrent http requests (default 1)
  • performance.http.requests (int): Total Number of http requests
  • performance.http.policy_rules (int): Number of CIDRs in the network policy
  • performance.realize.timeout (duration): Timeout of the realization of network policies (default 5m0s)

func ProbeCommand added in v1.13.0 

func ProbeCommand(url, protocol, executor string) []string

ProbeCommand generates a command to probe the provider url. The executor parameter can be used to change where the prober will run. For example, it could be "ip netns exec NAME" to run the prober in another namespace. We try to connect 3 times. This dates back to when we were using the OVS netdev datapath for Kind clusters, as the first packet sent on a tunnel was always dropped (https://github.com/antrea-io/antrea/issues/467). We may be able to revisit this now that we use the OVS kernel datapath for Kind. "agnhost connect" outputs nothing when it succeeds. We output "CONNECTED" in such case and prepend a sequence number for each attempt, to make the result more informative. Example output: 1: CONNECTED 2: TIMEOUT 3: TIMEOUT
