Is it possible to integrate Google Workspace tools such as Calendar, Sheets, and Forms with Workflows? For example, can you trigger a workflow from a Google Form or a Sheet? Turns out, this is not only possible but also easier than you might think. Let me show you how with a sample use case. Use case Imagine you are an administrator in charge of allocating virtual machines (VM) in your cloud infrastructure to users. Read More →

A few weeks ago, we announced third-party event sources for Eventarc, with the first cohort of third-party providers by our ecosystem partners. This blog post describes how to listen for events from one of those third-party providers, Datadog, and route them to a service in Google Cloud via Eventarc. Datadog is a monitoring platform for cloud applications. It brings together end-to-end traces, metrics, and logs to make your applications and infrastructure observable. Read More ↗︎

In Workflows, it’s easy to chain various services together into an automated workflow. For some use cases, you might need to pause workflow execution and wait for some input. This input could be a human approval or an external service calling back with data needed to complete the workflow. ​​With Workflows callbacks, a workflow can create an HTTP endpoint and pause execution until it receives an HTTP callback to that endpoint.

Careful what you wish for My last in-person conference before the pandemic was NDC London back in January 2020. I distinctly remember being quite tired at the beginning of 2020. For me, 2019 had been a long year with 50+ speaking engagements at a variety of conferences all around the world. I just wanted to take a short break in early 2020. Little did I know that the short break would turn into a 2. Read More →

At Google Cloud I/O, we announced the public preview of Cloud Run jobs. Unlike Cloud Run services that run continuously to respond to web requests or events, Cloud Run jobs run code that performs some work and quits when the work is done. Cloud Run jobs are a good fit for administrative tasks such as database migration, scheduled work like nightly reports, or doing batch data transformation. In this post, I show you a fully serverless, event-driven application to take screenshots of web pages, powered by Cloud Run jobs, Workflows, and Eventarc. Read More ↗︎

In Workflows, sometimes, you need to store some state, a key/value pair, in a step in one execution and later read that state in another step in another execution. There’s no intrinsic key/value store in Workflows. However, you can use Firestore as a key/value store and that’s what I want to show you here. If you want to skip to see some samples, check out workflow.yaml. If you want to learn more about it, keep reading. Read More →

We’re happy to announce that you can now create Eventarc triggers to directly target Workflows destinations. Available as a preview feature, it simplifies event-driven orchestrations by enabling you to route Eventarc events to Workflows without having an intermediary service. Integrating Eventarc and Workflows In a previous post, we talked about how to integrate Eventarc and Workflows. Since there was no direct integration between the two services, we had to deploy an intermediary Cloud Run service to receive events from Eventarc and then use the Workflows API to kick off a Workflows execution.

Terraform is increasingly the preferred tool for building, changing, and versioning infrastructure in Google Cloud and across clouds. In an earlier post, I showed how to create Eventarc triggers using Google Cloud Console or via the command line with gcloud. In this post, I show how to create the same triggers with the google_eventarc_trigger Terraform resource. See eventarc-samples/terraform on GitHub for the prerequisites and main.tf for full Terraform configuration. Define a Cloud Run service as an event sink Before you can create a trigger, you need to create a Cloud Run service as an event sink for the trigger. Read More ↗︎

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 a concrete example. Without path patterns Let’s say you want to listen for new file creations in a Cloud Storage bucket with an AuditLog trigger. Read More →

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 URL such as: https://<service-name>-<hash>-<region>.a.run.app/hello https://<service-name>-<hash>-<region>.a.run.app/bye Building APIs with Cloud Functions In Cloud Functions, you only have access to a function (no web server) and that function can only handle the base path: Read More →
