Working With Advanced Docker Operations

We all know, at this point, that Docker is the new hotness. Running individual containers can help with development but doesn’t do much for us when it’s time to deploy the application. There’s where orchestration comes in.

Docker Swarm is a great tool to use when you first get started with orchestration. Swarm is built into Docker. There’s no additional software to install. You can learn more about running services in Docker Swarm in my video course “Dive into Orchestration with Docker Swarm”.

Sometimes, however, you need more power. That’s where Kubernetes comes in. In my new course “Working with Advanced Docker Operations”, you get an introduction to running services in Kubernetes. You learn how to create new services, connect to shared storage, and deploy load balancers. It’s worth it just for the introduction to Kubernetes.

Running services in Kubernetes is only the beginning. You also need to be able to monitor those services. That’s why this course shows you how to setup Elasticsearch and Kibana to collect and view your container logs. You’ll also learn how to use Prometheus to gather performance data and how to view it all with Grafana.

The next step to running services is to use continuous integration and delivery to automatically build your Docker images and deploy your services to Kubernetes. This automation makes it easier to quickly and reliable deploy services. In “Working with Advanced Docker Operations,” you’ll learn how to create those CI/CD pipelines with GitLab.

Finally, I walk you through a number of use cases. You’ll learn how to use Docker to test MySQL database changes and backups. You learn how to deploy Wordpress and MySQL and how to manage applications that use a large number of dependencies. Finally, you’ll learn how deploy Jenkins in Kubernetes and automatically spin up new build agents on demand.

You can check these and all of my Docker courses at Packt Publishing.
