## Prerequisites

- JDK 11+ installed with JAVA_HOME configured appropriately

## Deploying application on OpenShift using Dekorate

```

mvn clean verify -Popenshift -Ddekorate.deploy=true

```

## Deploying application on OpenShift using Helm

First, make sure you have installed [the Helm command line](https://helm.sh/docs/intro/install/) and connected/logged to a kubernetes cluster.

Then, you need to install the example by doing:

```

helm install healthcheck ./helm --set app.route.expose=true --set app.s2i.source.repo=https://github.com/snowdrop/health-check-example --set app.s2i.source.ref=

```

**note**: Replace `` with one branch from `https://github.com/snowdrop/health-check-example/branches/all`.

And to uninstall the chart, execute:

```

helm uninstall healthcheck

```

## Deploying application on Kubernetes using Helm

Requirements:

- Have installed [the Helm command line](https://helm.sh/docs/intro/install/)

- Have connected/logged to a kubernetes cluster

You need to install the example by doing:

```

helm install healthcheck ./helm --set app.ingress.host=

```

And to uninstall the chart, execute:

```

helm uninstall healthcheck

```

## Running Tests on OpenShift using Dekorate

```bash

./run_tests_with_dekorate_in_ocp.sh

```

Alternativelly, tests can be executed against a specific Spring Boot or Dekorate version by passing the

version as a `-D=value` parameter. For instance overriding both the Spring Boot and the Dekorate versions using their corresponding version properties is done the following way:

```bash

./run_tests_with_dekorate_in_ocp.sh -Dspring-boot.version=2.7.3 -Ddekorate.version=2.11.1

```

## Running Tests on OpenShift using S2i from Source

```bash

./run_tests_with_s2i.sh

```

This script can take up to 3 parameters which are:

* `--repository-url`: repository to use to source the images from

* `--branch-to-test`: branch to use to source the images from

* `--maven-settings`: custom maven settings file

```bash

./run_tests_with_s2i.sh --repository-url "https://github.com/snowdrop/health-check-example" --branch-to-test branch-to-test --maven-settings "${HOME}/.m2/my-custom-maven-settings.xml"

```

## Running Tests on OpenShift using Helm

```

./run_tests_with_helm.sh

```

This script can take 2 parameters referring to the repository and the branch to use to source the images from.

```bash

./run_tests_with_helm_in_ocp.sh "https://github.com/snowdrop/health-check-example" branch-to-test

```

## Running Tests on Kubernetes using Helm

First, you need to create the k8s namespace:

```

kubectl create namespace 

```

Then, run the tests by specifying the container registry and the kubernetes namespace:

```

./run_tests_with_helm_in_k8s.sh  

```

For example:

```

./run_tests_with_helm_in_k8s.sh "quay.io/user" "myNamespace"

```
