kindcontainer's Issues
Kindcontainer doesn't work with testcontainers cloud
it should.
Maybe disallow use of `with*` methods after container start
I accidentally used the withKubectl method on the container reference after the container had started, and nothing happened. Maybe throw an IllegalStateException if the with* methods are used after start to give devs a hint that they should be using the, e.g., kubectl() method instead? 😬
Fluent API for `kubectl create ns`
it's missing!
Allow configuration of node port range
Sometimes it can be useful to configure the range of allowed node ports on containers that can start workloads. It should be configurable for KindContainer and K3sContainer.
Option to run K3S container with --docker flag
It may be useful to let the user configure the k3s server to run within the --docker.
With this flag the local docker images are available to the k3s pods
Incorrect LabelSelectorBuilder
All methods in LabelSelectorBuilder incorrectly returns the implementation (LabelSelectorBuilderImpl), rather than LabelSelectorBuilder.
Impact: The usage examples currently works "by accident", but any use of LabelSelectorBuilder where the type cannot be directly inferred will fail.
Fixed in PR#230.
Kind Container Fails to Start
I have the following simple test:
public class KindContainerTest {
KindContainer<?> KUBE = new KindContainer<>();
@Test
void runKindContainer() {
KUBE.start();
}
}Kind container fails to start with the following logs:

JUnit5 Support
Hey, I'm wondering if there are any plans from you side to support JUnit 5. Whenever I try to start a test which includes your container JUnit complains about not finding any tests. From my experience this related to the mixing of JUnit 5 and JUnit 4 stuff.
Best regards and thanks for your work, it looks relay intressting
Add support for API-Server-only testing
Not all tests need a fully functional kubernetes deployment. For many use-cases it'd be sufficient to just have a working API Server to run tests against.
Execution of `kubectl create secret` should be obfuscated
When running any kubectl commands, the execution is logged along with all the parameters. When using kubectl create secret this results in the secret data being logged in plain-text, including any passwords and other sensitive data.
It'd be really sweet if the values were to be obfuscated during logging. Or simply obfuscate everything after kubectl create secret.
Using the kindcontainer it fails on startup
Using Fefora 35
When it tries to start the Kind cluster if fails with :

[kubelet-check] It seems like the kubelet isn't running or healthy.
[kubelet-check] The HTTP call equal to 'curl -sSL http://localhost:10248/healthz' failed with error: Get "http://localhost:10248/healthz": dial tcp 127.0.0.1:10248: connect: connection refused.
Unfortunately, an error has occurred:
timed out waiting for the condition
This error is likely caused by:
- The kubelet is not running
- The kubelet is unhealthy due to a misconfiguration of the node in some way (required cgroups disabled)
If you are on a systemd-powered system, you can try to troubleshoot the error with the following commands:
- 'systemctl status kubelet'
- 'journalctl -xeu kubelet'
Additionally, a control plane component may have crashed or exited when started by the container runtime.
To troubleshoot, list all containers using your preferred container runtimes CLI.
Here is one example how you may list all Kubernetes containers running in cri-o/containerd using crictl:
- 'crictl --runtime-endpoint unix:///run/containerd/containerd.sock ps -a | grep kube | grep -v pause'
Once you have found the failing container, you can inspect its logs with:
- 'crictl --runtime-endpoint unix:///run/containerd/containerd.sock logs CONTAINERID'

Remove busybox
ApiServerContainer (and its EtcdContainer) rely on the busybox image to build images for execution. This slows down startup and can be avoided.
Add utility function for creating namespaces
Every now and then after creating a new namespace it can take a while for the responsible controllers to create the default SA for the new namespace - that can lead to race conditions. Those can be avoided by waiting for the SA to pop up before continuing. A convenience function for that would be really nice.
Improve readme for JUnit
Currently the examples in the readme only use JUnit 4. JUnit 5 is not mentioned at all.
I would suggest to choose one of the following options:
- Add JUnit 5 support
- Add JUnit 5 support and reduce visibility of JUnit 4 by only linking to the JUnit 4 examples.
- Replace JUnit 4 by JUnit 5 examples and not mention JUnit 4 at all
What is the best option?
Install local helm chart in container
Hi,
I'm currently playing around with your library and so far I really like how it can be used.
I have a helm chart that is build during my maven build and I want to test it with somthing like this:
private static final K3sContainer<?> K8S = new K3sContainer<>().withHelm3(helm -> {
helm.install
.namespace("my-namespace")
.createNamespace()
.run("my-release", "local-chart.tgz");
})
I don't want to publish the chart, because the chart should be published later in my build (but only when the tests are successful).
Is there a way to install a local helm chart currently?
K8s registry move
As described in this announcement of the k8s folks, they moved the registry of the kube-apiserver and etcd images, while for now redirecting the old locations.
I'm willing to supply a PR.
Fluent API for `kubectl label node`
it's not there!
Consider deploying the source along the binary
Hi,
It would be great if you could consider deploying the sources next to the jar.
By the way are you aware that bintray.com is becoming read-only starting tomorrow? See https://jfrog.com/blog/into-the-sunset-bintray-jcenter-gocenter-and-chartcenter/
