Deploying to Cloud Run using Cloud Build

This page explains how to automatically deploy Cloud Run services using Cloud Build. If you're new to Cloud Build, read the quickstarts and the build configuration overview first.

Cloud Run lets you run stateless images in a serverless environment. Using Cloud Build, you can deploy images from Artifact Registry to Cloud Run. You can deploy an existing image, build and deploy an image, or automate the deployment.

Before you begin

  • Enable the Cloud Build, Cloud Run, Artifact Registry, and Resource Manager APIs.

    Roles required to enable APIs

    To enable APIs, you need the Service Usage Admin IAM role (roles/serviceusage.serviceUsageAdmin), which contains the serviceusage.services.enable permission. Learn how to grant roles.

    Enable the APIs

Required Identity and Access Management permissions

  1. In the Google Cloud console, go to the Cloud Build Permissions page:

    Go to Permissions

  2. For your specified Cloud Build service account or default Cloud Build service account, set the status of the following roles to Enabled:

    • Cloud Run Admin (roles/run.admin) | Lets Cloud Build deploy new services to Cloud Run.
    • Storage Admin (roles/storage.admin) | Enables reading and writing from Cloud Storage.
    • Artifact Registry Writer (roles/artifactregistry.writer) | Allows pulling images from and writing to Artifact Registry.
    • Logs Writer (roles/logging.logWriter) | Allows log entries to be written to Cloud Logging.
    • Cloud Build Editor (roles/cloudbuild.builds.editor) | Allows your service account to run builds.

Building and deploying an image

Cloud Build lets you build an image, store the built image in Artifact Registry, and then deploy the image to Cloud Run.

To build and deploy an image:

  1. In your project root directory, create a config file named cloudbuild.yaml.

  2. In the build config file, add docker build steps to build the image and push it to Artifact Registry, and then add a gcloud build step to invoke the gcloud run deploy command to deploy the image on Cloud Run:

    steps: # Build the image - name: 'gcr.io/cloud-builders/docker'  args: ['build', '-t', 'LOCATION-docker.pkg.dev/PROJECT_ID/REPOSITORY/IMAGE', '.'] # Push the image to Artifact Registry - name: 'gcr.io/cloud-builders/docker'  args: ['push', 'LOCATION-docker.pkg.dev/PROJECT_ID/REPOSITORY/IMAGE'] # Deploy image to Cloud Run - name: 'gcr.io/google.com/cloudsdktool/cloud-sdk'  entrypoint: gcloud  args: ['run', 'deploy', 'SERVICE_NAME', '--image', 'LOCATION-docker.pkg.dev/PROJECT_ID/REPOSITORY/IMAGE', '--region', 'SERVICE_REGION'] images: - 'LOCATION-docker.pkg.dev/PROJECT_ID/REPOSITORY/IMAGE'

    Where:

    • REPOSITORY is the name of the Artifact Registry repository from where you deploy your image.
    • LOCATION is the location of your Artifact Registry repository, such as us-east1.
    • PROJECT_ID is your Google Cloud project ID where your image is stored.
    • SERVICE_NAME is the name of the Cloud Run service.
    • SERVICE_REGION is the region of the Cloud Run service you are deploying.
    • IMAGE is the name of your image in Artifact Registry.

  3. Navigate to your project root directory and run the following command, where LOCATION is one of the supported build regions to run the build:

     gcloud builds submit --region=LOCATION

After successful completion, a success message is displayed along with the URL of the deployed service.

Continuous deployment

You can automate the deployment of your software to Cloud Run by creating Cloud Build triggers. You can configure your triggers to build and deploy images whenever you update your source code.

To automate your deployment:

  1. In your repository root, add a config file named cloudbuild.yaml with steps to build the image, push the image to Artifact Registry, and then invoke the gcloud run deploy command:

    steps: # Build the image - name: 'gcr.io/cloud-builders/docker'  args: ['build', '-t', 'LOCATION-docker.pkg.dev/PROJECT_ID/REPOSITORY/IMAGE/SERVICE_NAME:$COMMIT_SHA', '.'] # Push the image to Artifact Registry - name: 'gcr.io/cloud-builders/docker'  args: ['push', 'LOCATION-docker.pkg.dev/PROJECT_ID/REPOSITORY/IMAGE/SERVICE_NAME:$COMMIT_SHA'] # Deploy image to Cloud Run - name: 'gcr.io/google.com/cloudsdktool/cloud-sdk'  entrypoint: gcloud  args:   - 'run'  - 'deploy'  - 'SERVICE_NAME'  - '--image'  - 'LOCATION-docker.pkg.dev/PROJECT_ID/REPOSITORY/IMAGE/SERVICE_NAME:$COMMIT_SHA'  - '--region'  - 'SERVICE_REGION' images: - 'LOCATION-docker.pkg.dev/PROJECT_ID/REPOSITORY/IMAGE/SERVICE_NAME:$COMMIT_SHA'

    Where:

    • REPOSITORY is the name of the Artifact Registry repository from where you deploy your image.
    • LOCATION is the location of your Artifact Registry repository, such as us-east1.
    • PROJECT_ID is your Google Cloud project ID where your image is stored.
    • SERVICE_NAME is the name of the Cloud Run service.
    • SERVICE_REGION is the region of the Cloud Run service you are deploying.
    • IMAGE is the name of your image in Artifact Registry.

    The $COMMIT_SHA substitution variable is populated by Cloud Build when triggered from a Git repository.

  2. Create a build trigger with the config file created in the previous step:

    1. Open the Triggers page:

      Go to the Triggers page

    2. Click Create Trigger.

    3. In the Name field, enter a name for your trigger.

    4. Under Region, select the region for your trigger.

    5. Under Event, select the repository event to start your trigger.

    6. Under Source, select your repository and the branch or tag name that will start your trigger. For more information on specifying which branches to autobuild, see Creating a build trigger.

    7. Under Configuration, select Cloud Build configuration file (YAML or JSON).

    8. In the Cloud Build configuration file location field, type cloudbuild.yaml after the /.

    9. Click Create to save your build trigger.

    Now, when you push new code to your repository, Cloud Build invokes a build and deploys the service to Cloud Run.

Code examples

Here are some sample repositories, each of which contains a sample application and a build config file to deploy application to Cloud Run:
