Today we’ve launched the most anticipated Cloud Run feature to beta: You can now access VPC networks from Cloud Run. As you can imagine, this is great news for scenarios like running your frontend on Cloud Run, and calling other backend microservices running on Kubernetes¹ over their private IPs.

In this article, we will connect to a Kubernetes service running on a private GKE cluster from Cloud Run. To visualize this, we’ll be configuring the following architecture: Read More →

Many microservices applications are primarily configured through environment variables nowadays. If you’re deploying to Cloud Run with gcloud CLI specifying a lot of environment variables might look rather painful: Read More →

In my previous article I have compared Google Cloud Run API to the open source Knative API specification, showed it in action and concluded that they’re largely compatible with several caveats.

In this article, I am digging another layer deeper and taking a look at whether the Knative runtime contract is fully satisfied by Cloud Run so that you could bring your applications from Kubernetes-based Knative implementation and have them work the same way? Read More →

Good news everyone: We finally managed to make deploying serverless containers as simple as gcloud run deploy --image=[IMAGE]. This command deploys an application to Cloud Run with the given docker image, but what does really happen behind the scenes to make this happen? Read More →

Google’s serverless containers as a service (CaaS) platform Cloud Run claims to implement the Knative API and its runtime contract. If true, this would mean that with the same YAML manifest file, you can run your apps on Google’s infrastructure, or a Kubernetes cluster anywhere. Read More →

I’ve been leading the Krew “kubectl plugin manager” (a Kubernetes sub-project). Today, Krew is used to distribute over 70 kubectl plugins. This week, I finally took some time to write my first proper plugin. Read More →

Knative project is usually explained as building blocks for “serverless on Kubernetes”. As a result of this implication, most Kubernetes users are not aware of what Knative can do for their non-serverless workloads: Better autoscaling and networking for stateless microservices on Kubernetes.

If you need to inspect kubectl network traffic, you can add verbose logging options (-v=8 or higher) to any kubectl command and you can see the URLs, request and response body/headers (except authorization). These headers usually are not complete, because more headers are added after the request is logged. To have a complete view, you need to intercept traffic using a local proxy like mitmproxy.
