Congratulations! You successfully completed a WHOLE lot of automation!

• Installed and configured Oracle VirtualBox using Ansible
• Deployed a fleet of auto-installed virtual Ubuntu servers
• Provisioned Kubernetes on these servers
• Deployed a MySQL service
• Deployed a demonstration web application that consumes the MySQL service

There are clearly things to consider to deploy an actual production web application. Here are a few things you can experiment with:

• create a playbook to bring the environment back up when the host reboots
• use of Kubernetes secrets instead of environment variables to configure the MySQL root password
• configure a Nginx virtual system for SSL Termination
• fork your own demo application and add https support
• Prometheus Node Exporter: explore metrics at the node (system) level; relatively easy to set up, it exposes useful metrics about host machine resources
• CI/CD Pipelines: Investigate a simple pipeline (Jenkins, GitLab CI, etc) to automate building a container image for your web app and trigger Deployments when code changes.

You have reached the end of this lab.

To clean up the environment from your host:

ansible-playbook destroy_fleet.yml
