Deploying from source code

This page describes how to deploy new services and new revisions to Cloud Run directly from source code using a single Cloud SDK command, gcloud beta run deploy with the --source flag.

Behind the scenes, this command uses Google Cloud buildpacks and Cloud Build to automatically build container images from your source code without having to install Docker on your machine or set up buildpacks or Cloud Build. That is, the single command described above does what would otherwise require the gcloud builds submit and the gcloud run deploy commands.

If a Dockerfile is present in the source code directory, the uploaded source code is built using that Dockerfile. If no Dockerfile is present in the source code directory, Google Cloud buildpacks automatically detects the language you are using and fetches the dependencies of the code to make a production-ready container image, using a secure base image managed by Google. (Each time you deploy, any needed security fixes are automatically picked up from the base image.)

Limitations of this feature

Deploying from source using gcloud run deploy --source is a convenience feature, and does not allow full customization of the build. For more control, build the container image using Cloud Build, for example, using gcloud builds submit, and then deploy the container image using, for example, gcloud run deploy --image)

Before you start

Make sure you have set up a new project for Cloud Run as described in the setup page.

Permissions required to deploy

You must have ONE of the following roles:

You must also set permissions for Cloud Build and for Cloud Storage

Deploying

To deploy from source code:

  1. Change to your source directory. Note that the source directory doesn't require a Dockerfile, but if a Dockerfile is present it will be used.

  2. Build and deploy your application:

    gcloud beta run deploy SERVICE --source .

    Replace SERVICE with the name you want for your service.

    Respond to any prompts to install required APIs by responding y when prompted. You only need to do this once for a project. Respond to other prompts by supplying the platform and region, if you haven't set defaults for these as described in the setup page.

  3. Wait for the build and deploy to complete. When finished, a message similar to this one is displayed:

    Service [my-app] revision [my-app-00000-xxx] has been deployed and is serving 100 percent of traffic. Service URL: https://my-app-texampleq-uc.a.run.app

    Upon deployment, note that this service revision serves 100% of traffic.

Automating building from source

As a best practice for avoiding unversioned changes in local source, Google recommends that you automatically deploy when changes are pushed to your Git repository. To make this easier, you can connect and configure continuous deployment to your Cloud Run service. By connecting your GitHub repositories to Cloud Run, you can configure builds and deploy your repositories without writing Dockerfiles or build files.

To configure automated builds, set up automation as described in the continuous builds page, making sure you choose the option for building source with Buildpacks.

What's next

After you deploy a new service, you can do the following:

You can automate the builds and deployments of your Cloud Run services using Cloud Build Triggers:
