Defining the Continuous Delivery environment

A minimum requirement for a Continuous Delivery environment is two clusters. One should be dedicated to running tests, building artifacts and images, and all other CD tasks. We can use it for simulating a production cluster. The second cluster will be used for deployments to production.

Why do we need two clusters? Can't we accomplish the same with only one?

While we certainly could get away with only one cluster, having two will simplify quite a few processes and, more importantly, provide better isolation between production and non-production services and tasks. The more we minimize the impact on the production cluster, the better. By not running non-production services and tasks inside the production cluster, we are reducing the risk. Therefore, we should have a production cluster separated from the rest of the environment.

Now let's get started and fire up those clusters.
