Summary
This chapter covered many new Crossplane patterns required to build the state-of-the-art resource composing control plane. I am explicitly mentioning the resource composing control plane instead of the infrastructure composing control plane because we no longer compose only external cloud provider resources. We experimented with resource referencing, secret propagation, and Helm deployment with the help of hands-on examples. We also looked at setting up monitoring with another hands-on example. In addition to these hands-on journeys, we also learned some debugging skills and ways to define our API boundaries.
The next chapter will cover different ways to extend and scale Crossplane.
