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.

Learn more by installing sqlmap and scan the test application for vulnerabilities.

You have reached the end of this lab.

To clean up the environment from your host:

ansible-playbook destroy_fleet.yml
