Automation for the Hello World Go app

This folder contains the Ansible playbook used to automate all the manual steps in building and deploying the example Hello Go app located elsewhere in this repository.

Usage

The Ansible playbook assumes you have the following installed on your workstation:

• Minikube
• Ansible

You will also need to install a Python dependencies via Python Pip:

pip3 install openshift

Once they are installed, you can run the playbook with:

ansible-playbook -i inventory main.yml

Once you're finished testing the Hello Go app in the Kubernetes cluster, you can clean it up by deleting the entire Minikube cluster with minikube delete, or you can run the following commands to delete just the necessary resources and leave the Minikube cluster running:

kubectl delete service hello-go
kubectl delete deployment hello-go

The above commands assume you have kubectl installed.

Scaling playbooks

There are two playbooks used to demonstrate scaling resources with Ansible:

1. scale-k8s_scale.yml: Scales the hello-go deployment using Ansible's k8s_scale module.
2. scale-strategic-merge.yml: Scales the hello-go deployment using Ansible's k8s module and the strategic-merge merge strategy.

Run the playbooks with:

ansible-playbook -i inventory scale-[type].yml
