You can now apply a path pattern when filtering in Eventarc. This is especially useful when you need to filter on resource names beyond exact match. Path pattern syntax allows you to define a regex-like expression that matches events as broadly as you like. Let’s take a look at…

Building APIs with Cloud Run If I want to build an API, I usually use Cloud Run. In Cloud Run, you run a container and in that container, you run a web server that handles a base URL in this format: https://<service-name>-<hash>-<region>.a.run.app You can then have the web server handle any path under that base…

I really like the idea of containers, a reproducible context that our apps can rely on. However, I really dislike having to create a Dockerfile to define my container images. I always need to copy & paste it from somewhere and it takes me some time to get it right. …

If you’re like me, you probably use VS Code to author your Workflows JSON or YAML. You also probably expect some kind syntax validation or auto-completion as you work on your workflow.

Introduction We recently announced a new feature, Events for Cloud Run for Anthos, to build event driven systems on Google Kubernetes Engine (GKE). In the announcement, we also stated that the solution is based on open-source Knative. In this blog post, I want to further explain the relationship between this new…

Challenges in connecting services When I think about my recent projects, I probably spent half of my time coding new services and the other half in connecting services. Service A calling Service B, or Service C calling an external service and using the result to feed into another Service D. Connecting services is one…
