Pushing Container Images to Google Cloud Artifact Registry (Step-by-Step)
When running Kubernetes locally with Docker Desktop, you have a handy superpower: your local Kubernetes cluster shares your computer's local Docker daemon. Any image you build via docker build is immediately available to your local pods without needing to push it to the internet. However, the moment you decide to deploy to a managed cloud cluster like Google Kubernetes Engine (GKE) , that magic…
This article provides a step-by-step guide for pushing container images to Google Cloud Artifact Registry. It highlights the need for a centralized container registry when deploying to managed cloud clusters like Google Kubernetes Engine (GKE), which previously relied on Google Container Registry (gcr.io) that has been deprecated.
The guide starts with prerequisites such as having a GCP account, the Google Cloud SDK installed, Docker running on the machine, and using a sample microservices GitHub repository. It then walks through authenticating with GCP, setting the active project, enabling the Artifact Registry API, creating a Docker repository in Artifact Registry, and configuring Docker authentication via the gcloud auth configure-docker command, which updates the local Docker configuration to automatically retrieve authentication tokens.
