So far we’ve let other tools decide how the agent gets hosted — adk run locally, or the little deploy script that packages everything up for Agent Platform runtime. Both are handy, but sometimes you just want a plain container: one image you can run on your laptop today, and on Cloud Run, GKE, or Agent Platform runtime (in bring-your-own-container mode) tomorrow. In this part we’ll build that image, set up the Agent Platform resource the managed services need, and deploy the same artifact to each of those targets. Let’s build it.
