## 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 rest-http ./helm --set app.route.expose=true --set app.s2i.source.repo=https://github.com/snowdrop/rest-http-example --set app.s2i.source.ref=
```
**note**: Replace `` with one branch from `https://github.com/snowdrop/rest-http-example/branches/all`.
And to uninstall the chart, execute:
```
helm uninstall rest-http
```
## 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 rest-http ./helm --set app.ingress.host=
```
And to uninstall the chart, execute:
```
helm uninstall rest-http
```
## Running Tests on OpenShift using Dekorate
```
./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
```
./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/rest-http-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_in_ocp.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/rest-http-example" branch-to-test
```
## Running Tests on Kubernetes with External Registry
```
mvn clean verify -Pkubernetes,kubernetes-it -Ddekorate.docker.registry= -Ddekorate.push=true
```
## 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"
```
