-# Spring Cloud Deployer Kubernetes
-A [Spring Cloud Deployer](https://github.com/spring-cloud/spring-cloud-deployer) implementation for deploying long-lived streaming applications and short-lived tasks to Kubernetes.
-
-This repository has been moved to [spring-cloud-deployer](https://github.com/spring-cloud/spring-cloud-deployer) where main has been updated to 2.9.0-SNAPSHOT
-
-_**2.9.x adds support for k8s 1.25 and drops support for k8s < 1.21**_
-
-## Kubernetes Compatibility
-
-| Deployer \ Kubernetes | 1.18 | 1.19 | 1.20 | 1.21 | 1.22 | 1.23 | 1.24 |
-|-----------------------|------|------|------|------|------|------|------|
-| **2.6.x**             | `✓`  | `✕`  | `✕`  | `✕`  | `✕`  | `✕`  | `✕`  |
-| **2.7.x**             | `✓`  | `✓`  | `✓`  | `✓`  | `?`  | `?`  | `?`  |
-| **2.8.x / MAIN**      | `✕`  | `✓`  | `✓`  | `✓`  | `✓`  | `✓`  | `✓`  |
-
-- `✓` Fully supported vers
-- `?` Due to breaking chans might not work _(e.g., ABAC vs RBAC)_. Also, we haven't thoroughly tested against this version.
-- `✕` Unsupported version.
-
-## Building
-
-Build the project without running tests using:
-
-```
-./mvnw clean install -DskipTests
-```
-
-## Integration tests
-
-The integration tests require a running Kubernetes cluster. A couple of options are listed below.
-
-### Minkube
-[Minikube](https://github.com/kubernetes/minikube) is a tool that makes it easy to run Kubernetes locally. It runs a single-node Kubernetes cluster inside a VM on your laptop for users looking to try out Kubernetes or develop with it day-to-day. 
-
-Follow the [getting started](https://minikube.sigs.k8s.io/docs/start/) guide to install Minikube.
-
-1. Start Minikube
-   ```shell
-   minkube start
-   ```
-2. Run the tests
-   ```shell
-   ./mvnw clean test
-   ```
-3. Stop Minikube
-   ```shell
-   minkube stop
-   ```
-
-
-### Google Container Engine
-While Minikube is very easy to run and test against, it is preferred to test against a GKE cluster. Minikube is not as useful since we test some parts of the external IP features that a LoadBalancer service provides.
-
-Create a test cluster and target it using something like (use your own project name, substitute --zone if needed):
-
-```
-gcloud container --project {your-project-name} clusters create "spring-test" --zone "us-central1-b" --machine-type "n1-highcpu-2" --scopes "https://www.googleapis.com/auth/compute","https://www.googleapis.com/auth/devstorage.read_only","https://www.googleapis.com/auth/logging.write" --network "default" --enable-cloud-logging --enable-cloud-monitoring
-gcloud config set container/cluster spring-test
-gcloud config set compute/zone us-central1-b
-gcloud container clusters get-credentials spring-test
-kubectl version
-```
-> :information_source: the last command causes the access token to be generated and saved to the kubeconfig file - it can be any valid kubectl command
-
-#### Running the tests
-
-Once the test cluster has been created, you can run all integration tests.
-
-As long as your `kubectl` config files are set to point to your cluster, you should be able to just run the tests. Verify your config using `kubectl config get-contexts` and check that your test cluster is the current context.
-
-Now run the tests:
-
-```
-$ ./mvnw test
-```
-
-NOTE: if you get authentication errors, try setting basic auth credentials:
-
-Navigate to your project and cluster on https://console.cloud.google.com/  and click on `show credentials`
-
-```bash
-$export KUBERNETES_AUTH_BASIC_PASSWORD=
-$export KUBERNETES_AUTH_BASIC_USERNAME=
-```
