Quickstart for Docker

Artifact Registry provides a single location for managing private packages and Docker container images.

This quickstart shows you how to:

  • Create a Docker repository in Artifact Registry
  • Set up authentication
  • Push an image to the repository
  • Pull the image from the repository

Before you begin

For commands in this quickstart, use either Cloud Shell or any environment where the Cloud SDK is installed. Cloud Shell includes a recent stable version of Docker.

  1. Accede a tu Cuenta de Google.

    Si todavía no tienes una cuenta, regístrate para obtener una nueva.

  2. En la página de selección de proyectos de Cloud Console, selecciona o crea un proyecto de Cloud.

    Ir a la página de selección de proyectos

  3. Comprueba que la facturación esté habilitada en tu proyecto.

  4. Habilita la API Artifact Registry.

    Habilita la API

  5. Instala e inicializa el SDK de Cloud.
  6. If you are not using Cloud Shell for this quickstart, install Docker.

    If you're using a Linux-based operating system, such as Ubuntu or Debian, add your username to the docker group so that you can run Docker without using sudo:

    sudo usermod -a -G docker ${USER}

    Log out and log back in for group membership changes to take effect. If you are using a virtual machine, you may need to restart the virtual machine for membership changes to take effect.

  7. Open Docker. To ensure that Docker is running, run the following Docker command, which returns the current time and date:
  8. docker run busybox date

Create a Docker repository

Create a Docker repository to store the sample image for this quickstart.

Console

  1. Open the Repositories page in the Cloud Console.

    Open the Repositories page

  2. Click Create Repository.

  3. Specify quickstart-docker-repo as the repository name.

  4. Choose Docker as the format.

  5. Under Location Type, select Region and then choose the location us-central1.

  6. Click Create.

The repository is added to the repository list.

gcloud

  1. Run the following command to create a new Docker repository named quickstart-docker-repo in the location us-central1 with the description "docker repository".

    gcloud artifacts repositories create quickstart-docker-repo --repository-format=docker \
    --location=us-central1 --description="Docker repository"
    
  2. Run the following command to verify that your repository was created.

    gcloud artifacts repositories list
    

For more information about Artifact Registry commands, run the command gcloud artifacts.

Configure authentication

Before you can push or pull images, configure Docker to use the gcloud command-line tool to authenticate requests to Artifact Registry.

To set up authentication to Docker repositories in the region us-central1, run the following command:

gcloud auth configure-docker us-central1-docker.pkg.dev

Obtain an image to push

For this quickstart, you will push a sample image named hello-app.

  1. Change to a directory where you want to save the image.
  2. Run the following command to pull version 1.0 of the image.

    docker pull us-docker.pkg.dev/google-samples/containers/gke/hello-app:1.0
    

Add the image to the repository

Before you push the Docker image to Artifact Registry, you must tag it with the repository name.

Tag the image with a registry name

Tagging the Docker image with a repository name configures the docker push command to push the image to a specific location. For this quickstart, the host location is us-central1-docker.pkg.dev.

Run the following command to tag the image as quickstart-image:tag1:

docker tag us-docker.pkg.dev/google-samples/containers/gke/hello-app:1.0 \
us-central1-docker.pkg.dev/PROJECT/quickstart-docker-repo/quickstart-image:tag1

Where

  • PROJECT is your Google Cloud Console project ID. If your project ID contains a colon (:), see Domain-scoped projects.
  • us-central1 is the repository location.
  • 'docker.pkg.dev` is the hostname for Docker repositories.
  • quickstart-image is the image name you want to use in the repository. The image name can be different than the local image name.
  • tag1 is a tag you're adding to the Docker image. If you didn't specify a tag, Docker will apply the default tag latest.

You are now ready to push the image to the repository you created.

Push the image to Artifact Registry

After you have configured authentication and tagged the local image, you can push the image to the repository that you created.

To push the Docker image, run the following command:

docker push us-central1-docker.pkg.dev/PROJECT/quickstart-docker-repo/quickstart-image:tag1

Replace PROJECT with your Google Cloud Console project ID. If your project ID contains a colon (:), see Domain-scoped projects.

Pull the image from Artifact Registry

To pull the image from Artifact Registry onto your local machine, run the following command:

docker pull us-central1-docker.pkg.dev/PROJECT/quickstart-docker-repo/quickstart-image:tag1

Replace PROJECT with your Google Cloud Console project ID. If your project ID contains a colon (:), see Domain-scoped projects.

You should see output similar to the following:

latest: Pulling from [PROJECT-ID]/quickstart-image:tag1
Digest: sha256:70c42...
Status: Image is up to date for us-central1-docker.pkg.dev/PROJECT/quickstart-docker-repo/quickstart-image:tag1

Clean up

To avoid incurring charges to your Google Cloud account for the resources used in this quickstart, follow these steps.

Before you remove the repository, ensure that any images you want to keep are available in another location.

To delete the repository:

Console

  1. Open the Repositories page in the Cloud Console.

    Open the Repositories page

  2. In the repository list, select the quickstart-docker-repo repository.

  3. Click Delete.

gcloud

To delete the quickstart-docker-repo repository, run the following command:

gcloud artifacts repositories delete quickstart-docker-repo --location=us-central1
