What's Changed

Highlights

Testcontainers 1.16.3 includes many changes, but there are two key highlights in this release:

k3s module (#4582) @rnorth, @kiview

We've had plenty of feedback from users wanting to use Testcontainers to help test Kubernetes components.
In particular, this is useful for people developing Kubernetes controllers/operators, who need something more than just a mocked Kubernetes API.
In this release we're bringing the k3s module, which gives you a neat way to spin up the K3S lightweight Kubernetes inside of a container.
We believe that k3s hits a sweet spot for ease of use and performance, so is a good option for testing Kubernetes components.

Now, launching a lightweight single-node Kubernetes cluster within your tests is easy as:

K3sContainer k3s = new K3sContainer(DockerImageName.parse("rancher/k3s:v1.21.3-k3s1"));
k3s.start();

String kubeConfigYaml = k3s.getKubeConfigYaml();
ApiClient client = Config.fromConfig(new StringReader(kubeConfigYaml));

// now use `client` to talk to your cluster!

Check out the docs to find out more!

Selenium 4 compatibility (#4914) @GannaChernyshova, @tobiasstadler, @kiview, @rnorth

Selenium 4 was announced a while back, but we needed to make some changes to Testcontainers' Selenium/Webdriver module for compatibility.
We're happy to announce that these changes have now been made, so you can now use Selenium 4 with Testcontainers!

As part of this upgrade we have to drop compatibility with Selenium 2, but believe that this will not have any practical impact.
