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 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=<branch-to-use>

note: Replace <branch-to-use> 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
• Have connected/logged to a kubernetes cluster

You need to install the example by doing:

helm install healthcheck ./helm --set app.ingress.host=<your k8s domain>

And to uninstall the chart, execute:

helm uninstall healthcheck

Running Tests on OpenShift using Dekorate

./run_tests_with_dekorate.sh

Running Tests on OpenShift using S2i from Source

./run_tests_with_s2i.sh

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

./run_tests_with_s2i.sh "https://github.com/snowdrop/health-check-example" branch-to-test

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.

./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 <the k8s namespace>

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

./run_tests_with_helm_in_k8s.sh <your container registry: for example "quay.io/user"> <the k8s namespace>

For example:

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