Docker is a amazing container platform, it helps fast deploying and scaling service among multiple servers (called cluster). But Docker is not good at managing instances on different servers, DevOps need a new software. A great thank to Google, Kubernetes (K8s) is well fitted for
automating deployment, scaling, and management of containerized applications.
In this post I will show my first impression on Kubernetes and how I setup a deployment of MySQL+PhpMyAdmin+Nginx and assign a ssl certificate automatically with cert-manager and the steps of my troubleshooting.
