Deploying Applications to Google Cloud Run

Deploying Applications to Google Cloud Run

Learn how to deploy applications to Google Cloud Run.

We'll cover the following...

Choosing a platform

We might also need to choose the platform. As we’ve already mentioned, Cloud Run is based on Knative, which can run on any Kubernetes cluster. Similarly, GCloud allows us to deploy serverless applications almost anywhere. We can choose between managed, gke, and kubernetes. The managed platform is Cloud Run, which we’re exploring right now.

Finally, we’ll have to specify the Google Cloud project in which we’ll run the application.

Note: We could specify quite a few other things. But we’ll let you explore them on your own after you finish with this section, if you still feel that Google Cloud Run might be the right solution for some of your use cases.

Deploying the application

With all that in mind, here is the command we’ll execute.

Press + to interact
gcloud run deploy \
    devops-toolkit-series \
    --image $IMAGE \
    --region $REGION \
    --allow-unauthenticated \
    --port 80 \
    --concurrency 100 \
    --platform managed \
    --project $PROJECT_ID

After approximately one minute, our application has been deployed and is available. That’s all it took. A single command, with a few simple arguments, deployed our application packaged as a container image. Let’s confirm that by outputting all the applications managed by Cloud Run inside that project.

Press + to interact
gcloud run services list \
    --region $REGION \
    --platform managed \
    --project $PROJECT_ID

The output is as follows.

Press + to interact
 SERVICE                REGION    URL                                                    LAST DEPLOYED BY                                   LAST DEPLOYED AT

Similarly, we can retrieve all the revisions of an application.

Press + to interact
gcloud run revisions list \
    --region $REGION \
    --platform managed \
    --project $PROJECT_ID

The output is as follows.

There’s not much to look at since we only deployed one revision of the application. The revisions will start piling up if we start deploying new releases.

Finally, let’s ...
