Docker Registry

There are several ways to set up a Docker registry. Here are the most common methods:

[1] Docker Hub.

Using a public DockerRegistry, like Docker Hub. It is a hosted registry service provided by Docker, and it's the easiest way to start using a Docker registry. You just need to create an account on Docker Hub and start pushing your images.

[2] Running a Private Docker Registry

Docker provides an official image for setting up your own registry. You can run a private Docker registry on your own server or cloud provider.

Using Docker CLI

docker run -d -p 5000:5000 --name registry registry:2

This command will pull the official registry image and run it as a container on port 5000.

Using Docker Compose Create a docker-compose.yml file:

services:
  registry:
    image: registry:2
    ports:
      - "5000:5000"
    environment:
      REGISTRY_STORAGE_FILESYSTEM_ROOTDIRECTORY: /var/lib/registry
    volumes:
      - ./data:/var/lib/registry

[3] Using AWS ECR (Elastic Container Registry)

AWS ECR is a managed container image registry service. You can integrate it with your AWS account and use it to store your Docker images.

Steps:

1. Create a repository in AWS ECR.
2. Configure your Docker CLI to authenticate with ECR: sh

aws ecr get-login-password --region your-region | docker login --username AWS --password-stdin your-account-id.dkr.ecr.your-region.amazonaws.com

3. Tag and push your image:

docker tag your-image:latest your-account-id.dkr.ecr.your-region.amazonaws.com/your-repository:tag
docker push your-account-id.dkr.ecr.your-region.amazonaws.com/your-repository:tag

[4] Using Google Container Registry (GCR)

GCR is a fully managed Docker registry service by Google Cloud Platform.

Steps:

1. Authenticate Docker with GCR: sh

gcloud auth configure-docker

2. Tag and push your image: sh

docker tag your-image gcr.io/your-project-id/your-image
docker push gcr.io/your-project-id/your-image

[5] Using Azure Container Registry (ACR)

ACR is a managed Docker registry service by Microsoft Azure.

Steps:

1. Create a registry in Azure.
2. Log in to the registry: sh

az acr login --name yourRegistryName

3. Tag and push your image: sh

docker tag your-image yourRegistryName.azurecr.io/your-image
docker push yourRegistryName.azurecr.io/your-image

[6] Using Harbor

Harbor is an open-source container image registry that secures images with role-based access control, scans images for vulnerabilities, and signs images as trusted.

Using Docker Compose Create a harbor.yml file with your configuration. See at the 06.Harbor for details >>>
