Create remote repositories

This page describes how to create Artifact Registry remote repositories.

Remote repositories store artifacts from the following upstream sources:

Standard Artifact Registry repositories.
External sources such as Docker Hub, Maven Central, the Python Package Index (PyPI), Debian or CentOS.

A remote repository acts as a proxy for the upstream source so that you have more control over your dependencies. The first time that you request a version of a package, Artifact Registry downloads and caches the package in the remote repository. The next time you request the same package version, Artifact Registry serves the cached copy.

If you request an artifact from an upstream source that doesn't exist, or doesn't contain the version you specified, then the request will fail.

The other repository modes are:

Standard: The default repository mode. You upload or publish artifacts such as private packages directly to standard repositories. Although you can download directly from individual standard repositories, accessing groups of repositories with a virtual repository simplifies tool configuration.
Virtual: A repository that acts as a single access point for multiple upstream repositories, including remote and standard repositories.

For more details on how remote repositories work, see the Remote repository overview.

Before you begin

Enable Artifact Registry, including enabling the Artifact Registry API and installing Google Cloud CLI.
Optional: configure defaults for the gcloud CLI commands.
If you require customer-managed-encryption keys (CMEK) to encrypt repository content, then create and enable a key in Cloud KMS for the repository.
If you want to authenticate to an upstream repository, then enable the Secret Manager API.
```
gcloud services enable secretmanager.googleapis.com \
    --project=PROJECT_ID
```
If Artifact Registry is in a VPC Service Controls service perimeter, then enable the Access Context Manager API if it is not already enabled.
```
gcloud services enable accesscontextmanager.googleapis.com \
    --project=PROJECT_ID
```
If you want to set an Artifact Registry repository as your upstream, and it's in a different project than your remote repository, then you need to grant the service account for the remote repository project access to the upstream repository project before creating the remote repository.
Grant the Service Agent role
Remote repositories use the Artifact Registry Service Agent to authenticate to Artifact Registry upstream repositories. You must grant the remote repository service agent read access to the upstream repository.
To grant the remote repository service agent the Artifact Registry Service Agent role on the upstream repository, run the following command:
```
  gcloud projects add-iam-policy-binding UPSTREAM_REPOSITORY \
      --member serviceAccount:service-REMOTE_PROJECT_NUMBER@gcp-sa-artifactregistry.iam.gserviceaccount.com \
      --location=REGION \
      --project=UPSTREAM_PROJECT_ID \
      --role roles/artifactregistry.serviceAgent
  
```
Replace the following:
- UPSTREAM_REPOSITORY is the ID of the upstream repository. Artifact Registry upstream repositories must be standard mode repositories.
- REMOTE_PROJECT_NUMBER is the project number of the Google Cloud project for your remote repository.
- REMOTE_PROJECT_ID is the ID of the Google Cloud project for your remote repository.
- REGION is the region in which you want to create your remote repository.
- UPSTREAM_PROJECT_ID is the ID of the Google Cloud project with the upstream repository.

Required roles

To get the permissions that you need to manage repositories, ask your administrator to grant you the following IAM roles:

Create remote repositories and grant access to individual repositories: Artifact Registry Admin (roles/artifactregistry.admin) on the project
Save your upstream repository credentials in a secret version: Secret Manager Admin (roles/secretmanager.admin) on the project
Grant access to upstream sources outside a VPC Service Controls service perimeter: Access Context Manager Editor (roles/accesscontextmanager.policyEditor) on the project, folder, or organization where the access policy is applied

For more information about granting roles, see Manage access to projects, folders, and organizations.

You might also be able to get the required permissions through custom roles or other predefined roles.

Create a remote repository

When you create a remote repository, you must configure the following settings, which can't be changed after the repository is created:

Artifact format.
Repository mode set to remote.
Remote repository upstream source.
Repository location.
Encryption with Google-owned and Google-managed keys or customer-managed encryption keys. Artifact Registry uses Google-owned and Google-managed encryption keys by default.

Artifact Registry enforces organization policy constraints that require CMEK to encrypt resources or limit which Cloud KMS keys can be used for CMEK protection.

Create a remote repository using Google Cloud console

Open the Repositories page in the Google Cloud console.

Open the Repositories page
Click Create Repository.
Specify the repository name. For each repository location in a project, repository names must be unique.
In the Format section, select the repository format.
In the Repository mode section, select Remote.
In the Remote repository source section, select one of the following ways to enter your upstream repository URL:
- Select the listed preset upstream source for your format type.
- Select Custom to specify the full URL to a public or private repository for supported formats.
- Select Artifact Registry repository to select a standard Artifact Registry repository.
If you selected Custom, then in the Custom repository field, enter the full repository URL. The URL cannot be changed after the repository is created.

For examples of some common upstream URLs, see Custom upstreams.
If you selected Artifact Registry repository:
1. In the Artifact Registry repository field, enter the full name of the repository you want to use as your upstream, or click Browse to view a list of repositories that you have access to view. Only repositories of the same format as your remote repository are listed.
2. Click the name of the repository you want to use as an upstream.
3. Click Select.
If you selected one of the preset upstreams or entered a full URL using the Custom button, then in the Remote repository authentication mode choose one of:
- Authenticated: to enter your username and secret for authentication to your upstream repository.
- Unauthenticated: to skip authentication to the upstream repository.
If you selected Authenticated, enter the following:
- In the Username field, enter your username for the upstream repository.
- In the Secret field, enter the secret version where you saved your password for the upstream repository.
You can edit these values after you create the repository. For more information on authentication to remote repository upstreams, see Configure authentication to remote repository upstreams.

Note: You can add authentication to an unauthenticated repository after you create the repository, but you can't change an authenticated repository to an unauthenticated repository after you create it.
In the Location Type section, choose the location for the repository:
1. Choose the location type: Region or Multi-Region. The list of locations changes to reflect your selection.
2. In the Region or Multi-region list, select a location.
For information about location types and supported locations, see Repository locations
Add a description for the repository. Descriptions help to identify the purpose of the repository and the kind of artifacts it contains.

Don't include sensitive data, since repository descriptions are not encrypted.
If you want to use labels to organize your repositories, click Add Label and enter the key-value pair for the label. You can add, edit, or remove labels after you create the repository.
In the Encryption section, choose the encryption mechanism for the repository.
- Google-managed key - Encrypt repository content with a Google-owned and Google-managed key.
- Customer-managed key - Encrypt repository content with a key that you control through Cloud Key Management Service. For key setup instructions, see Setting up CMEK for repositories.
If you want to use cleanup policies to delete unused artifacts, in the Cleanup policies section:
1. Select Dry run to test your policy before applying it.
2. Click Add policy to add a keep or delete policy to your repository.
3. Give your cleanup policy a descriptive name in the Name field.
4. In the Policy type section, select one of:
  - Conditional delete: deletes artifacts based on conditions you define.
  - Conditional keep: keeps artifacts based on conditions you define.
  - Keep most recent versions: Keeps a set number of most recent versions per package.
    
    Caution: if you set Package prefixes for this policy, only artifacts matching the package prefixes will be kept, up to the number set for most recent versions.
  For more details on cleanup policies, see Configure cleanup policies.
Click Create.

Artifact Registry creates the repository and adds it to the list of repositories.

After you have created the repository:

Grant access to the repository.
Configure Docker, package managers, and other third-party clients to authenticate to repositories.
- Container images: Docker, Helm
- Language packages: Java, Node.js, Python, Go
- OS packages: Debian, RPM
- Other: Kubeflow Pipeline templates
Configure Artifact Registry remote repositories to authenticate to their upstream sources.
- Container images: Configure remote repository authentication to Docker Hub
- Language packages:
- User-defined custom upstreams: Configure authentication to remote repository upstreams

Create a remote repository using Terraform

Use the google_artifact_registry_repository resource to create repositories. terraform-provider-google version 5.0.0 or newer is required.

If you are new to using Terraform for Google Cloud, see the Get Started - Google Cloud page on the HashiCorp website.

The following example defines the provider and a remote repository with the Terraform resource name my-repo.

Docker

provider "google" {
    project = "PROJECT-ID"
}

resource "google_artifact_registry_repository" "my-repo" {
  location      = "LOCATION"
  repository_id = "REPOSITORY_ID"
  description   = "DESCRIPTION"
  format        = "docker"
  kms_key_name = "KEY"
  mode          = "REMOTE_REPOSITORY"
  remote_repository_config {
    description = "CONFIG_DESCRIPTION"
    docker_repository {
      public_repository = "DOCKER_HUB"
    }
  }
  cleanup_policy_dry_run = DRY_RUN_STATUS
  cleanup_policies {
    id     = "POLICY_NAME"
    action = "DELETE"
    condition {
      tag_state    = "TAG_STATE"
      tag_prefixes = ["TAG_PREFIX", "TAG_PREFIX_N"]
      older_than   = "TIME_SINCE_UPLOAD"
    }
  }
  cleanup_policies {
    id     = "POLICY_NAME"
    action = "KEEP"
    condition {
      tag_state             = "TAG_STATE"
      tag_prefixes          = ["TAG_PREFIX", "TAG_PREFIX_N"]
      package_name_prefixes = ["PKG_PREFIX", "PKG_PREFIX_N"]
    }
  }
  cleanup_policies {
    id     = "POLICY_NAME"
    action = "KEEP"
    most_recent_versions {
      package_name_prefixes = ["PKG_PREFIX", "PKG_PREFIX_N"]
      keep_count            = KEEP_COUNT
    }
  }
}

- PKG_PREFIX, PKG_PREFIX_N are package prefixes to apply the policy to.
- TIME_SINCE_UPLOAD is the time since an artifact version was uploaded to the repository, specified as a duration. You can specify durations of seconds, minutes, hours, or days by appending s, m, h, or d respectively.
- KEEP_COUNT is the number of versions per package of an artifact to keep in your repository.

Maven

If you don't specify a version policy, Artifact Registry creates a Maven repository that stores both snapshot and release versions of packages by default.

provider "google" {
    project = "PROJECT-ID"
}

resource "google_artifact_registry_repository" "my-repo" {
  location      = "LOCATION"
  repository_id = "REPOSITORY_ID"

- KEEP_COUNT is the number of versions per package of an artifact to keep in your repository.

To store snapshot and release versions in different repositories, specify a version policy for the repository using a maven_config block. This block supports the following settings:

version_policy sets the version policy with one of the following values:
- VERSION_POLICY_UNSPECIFIED: Store snapshot and release packages. This is the default setting.
- RELEASE: Store release packages only.
- SNAPSHOT: Store snapshot packages only.
allow_snapshot_overwrites configures a repository with a SNAPSHOT version policy to accept non-unique snapshots that overwrite existing versions in the repository.

The following example defines a Maven repository with a release version policy.

provider "google" {
project = "my-project"
}

resource "google_artifact_registry_repository" "my-repo" {
provider = google-beta

location = "LOCATION"
repository_id = "my-repo"
description = "Maven repository"

Artifact Registry creates your repository. Run the following command to view a description of the repository:

gcloud artifacts repositories describe REPOSITORY \
    --location=LOCATION

After you have created the repository:

Grant access to the repository.
Configure Docker, package managers, and other third-party clients to authenticate to repositories.
- Container images: Docker, Helm
- Language packages: Java, Node.js, Python, Go
- OS packages: Debian, RPM
- Other: Kubeflow Pipeline templates
Configure Artifact Registry remote repositories to authenticate to their upstream sources.
- Container images: Configure remote repository authentication to Docker Hub
- Language packages:
- User-defined custom upstreams: Configure authentication to remote repository upstreams

Edit repository descriptions

You can change the repository description from Google Cloud console or the gcloud CLI.

Console

Open the Repositories page in the Google Cloud console.

Open the Repositories page
In the repository list, select the repository and click Edit Repository.
Edit the repository description and then click Save.

gcloud

To update the repository description, run the command:

gcloud artifacts repositories update REPOSITORY \
    --project=PROJECT \
    --location=LOCATION \
    --description="DESCRIPTION"

Replace the following:

REPOSITORY: the name of the repository. If you configured a default repository, you can omit this flag to use the default.
PROJECT: the Google Cloud project ID. If this flag is omitted, the current or default project is used.
LOCATION: a regional or multi-regional location. Use this flag to view repositories in a specific location. If you configured a default location, you can omit this flag to use the default.
DESCRIPTION: a description for the repository.

Access to upstream sources in a service perimeter

Services in a VPC Service Controls service perimeter have restricted access to resources outside the perimeter.

You can allow or deny access to upstream sources within a specified Google Cloud project and location.

By default, Artifact Registry denies access to upstream sources if you have not explicitly granted access.

For Artifact Registry the required role is the Artifact Registry Administrator (roles/artifactregistry.admin).

View settings for upstream sources

To view the configuration for a specific project and location combination, run the following command:

gcloud artifacts vpcsc-config describe \
    --project=PROJECT_ID \
    --location=LOCATION

For example, use the following command to view settings for remote repositories in us-east1 in the project my-project:

gcloud artifacts vpcsc-config describe \
    --project=my-project \
    --location=us-east1

Allow access to upstream sources

To allow access to upstream sources in a specified location, run the command:

gcloud artifacts vpcsc-config allow \
    --project=PROJECT_ID \
    --location=LOCATION

For example, use the following command to allow all remote repositories in us-east1 in the project my-project to access their upstream sources outside of the perimeter:

gcloud artifacts vpcsc-config allow \
    --project=my-project \
    --location=us-east1

Deny access to upstream sources

When you deny access to upstream sources, existing cached artifacts in remote repositories are still available.

To deny access to upstream sources in a specified location, run the command:

gcloud artifacts vpcsc-config deny \
    --project=PROJECT_ID \
    --location=LOCATION

For example, use the following command to block access to upstream sources outside of the perimeter for all remote repositories in us-west1 in the project my-project:

gcloud artifacts vpcsc-config deny \
    --project=my-project \
    --location=us-west1
