Private registry

As explained in Bootstrapping Microservices, Second Edition: With Docker, Kubernetes, GitHub Actions, and Terraform

A private container registry is a container registry whose stored images are restricted to authorized users or systems.

A private container registry stores container images behind access restrictions, giving a proprietary application a controlled place to publish images before deployment. section 3.0

Use the registry in a deployment workflow:

• Package a microservice and its dependencies into a Docker image. section 3.0
• Publish the image to the private registry. section 3.6
• Pull or instantiate the image locally, then deploy it to a Kubernetes cluster. section 3.0 section 3.6

Creating an Azure registry

Create the registry through the Azure portal by choosing Create a Resource, searching for Container Registry, selecting the Microsoft service, and completing its configuration. Review its authentication details before publishing images. Destroy unused resources later to avoid continued charges; the same registry can subsequently be defined with Terraform. section 3.9.1 section 7.9

Figure 3.3 Publishing Docker images to our private container registry in the cloud

Shows the path from a Node.js microservice project to a Docker image, private cloud registry, and eventual Kubernetes deployment. section 3.6

How Bootstrapping Microservices, Second Edition: With Docker, Kubernetes, GitHub Actions, and Terraform covers it

How deep it goes

Builds a registry manually through Azure portal, then revisits its creation through Terraform.

Examples

Uses Azure portal creation, authentication details, and publishing a video-streaming microservice image.

What it assumes

Assumes a Dockerized microservice and cloud account; introduces registry creation before deployment.

What you can do after

Operate/configure a private registry manually in Azure and prepare it for image publication.

How it connects

Connects Docker images, microservices, Kubernetes clusters, Azure, and Terraform.
