Components of a software delivery pipeline
We’ll start by covering the basic components of a modern CI/CD system and how they communicate with each other to automate your processes.
Implementing a CI/CD system
Once we’re familiar with the concepts, we’ll be automating the delivery of our ecommerce system, going through the process of containerising your application, using image registries and delivery of the software upon updates.
Kubernetes supports several mechanisms to trigger actions deliberately. These mechanisms are useful for things like database migrations, regular backups etc. We’ll be implementing them in our reference system to continue automation of our pipeline.
Building a monitoring pipeline
After our system is deployed, we’ll be implementing a real monitoring suite that aggregates all the logs of the system and allows real-time inspection of various metrics, to ensure visibility into our cluster.
Automatic software updates and rollbacks
Finally, we’ll introduce gradual updates of our system through a technique called blue/green deployments. This allows us to test new features out in a controlled manner, without impacting the whole system.
