Google Cloud Deploy is introducing a brand new function known as deployment verification, with this function builders and operators will have the ability to orchestrate and execute submit deployment testing with out having to undertake a extra in depth testing integration, like by utilizing Cloud Deploy notifications or manually testing.
The 2021 State of DevOps report confirmed us that steady testing is a powerful predictor of profitable steady supply. By incorporating early and frequent testing all through the supply course of, with testers working alongside builders all through, groups can iterate and make adjustments to their product, service, or software extra rapidly.
What about performing submit supply testing, to find out if sure situations are met to additional validate a deployment? For many, the power to run these checks stays important to their enterprise and is an oft desired desk stakes functionality from a steady supply device.
As shared in our earlier submit this previous August, Cloud Deploy makes use of Skaffold for render and deploy operations. This new function depends on a brand new Skaffold part named ‘confirm’, this part permits builders and operators so as to add a listing of check containers to be run submit deployment and monitored for fulfillment/failure.
The way to use
We’re going to use thepython-hello-world from Cloud Code Samples to indicate how deployment verification works. With our Cloud Construct set off and file configured and Cloud Deploy Pipeline created, we are able to begin to strive the submit deployment verification function.
First, we have to modify the skaffold.yaml to insert the brand new confirm part:
The likelihood to make use of any container picture (both standalone containers or constructed by Skaffold) provides builders the pliability to carry out easy checks as much as extra complicated eventualities. For this case we’re going to use ‘wget’ to examine if the “/good day” web page exists and if it is up (http 200 response).
Though we are able to use Kubernetes readiness probe to examine if our software/pod is able to obtain requests, this new Cloud Deploy function permits us to carry out managed and pre-defined checks. We will examine software metrics and/or execute integration checks, for instance.
Now let’s check out our clouddeploy.yaml. The submit deployment verification can be utilized for various targets primarily based on completely different Skaffold profiles, in our case the ‘dev’ goal, additionally we have to configure the targets we wish to have deployment verification, as highlighted beneath.
This new technique configuration permits for potential extra Cloud Deploy deployment methods sooner or later, for now we’re going to use the usual one.
After these adjustments, we are able to set off our CI/CD course of utilizing ‘gcloud builds submit’ or pushing the code to the supply repo with the intention to set off Cloud Construct. After the construct part (also referred to as Steady Integration) Cloud Construct will create a Google Cloud Deploy launch and deploy it by the desired supply pipeline onto our ‘dev’ goal.
Necessary: Like Cloud Deploy rendering and deployment, the verification container runs on Cloud Construct safe and hosted surroundings, and never in the identical surroundings of your software, so that you must expose the applying to execute the submit deployment verification, or you need to use Cloud Construct Personal swimming pools.
To examine the deployment standing, open Cloud Deploy then navigate to the supply pipeline and click on on the final launch within the launch checklist. On the discharge particulars web page, choose the final rollout from the rollout checklist.
The above screenshot exhibits the submit deployment verification was profitable. You may click on on verification logs to see the main points. If we modify the handle of our ‘wget’ verification on skaffold.yaml and re-run the method, we are able to see what occurs when the verification fails.
When the deployment verification fails, the rollout also needs to fail.
All of the deployment verification checks must move. If any deployment verification check fails the rollout additionally fails. Nonetheless, it’s potential to re-run submit deployment verification for a failed rollout. Additionally it’s potential to obtain a Pub/Sub notification when a verification is began and accomplished.

The Google Cloud Deploy tutorials web page has been up to date with a deployment verification walkthrough. This interactive tutorial will take you thru the steps to arrange and use the Google Cloud Deploy service. This pipeline consists of automated deployment verification, which runs checks at every stage to check whether or not the applying has been efficiently deployed.
Complete, easy-to-use, and cost-effective DevOps instruments are key to constructing an environment friendly software program growth group, and it’s our hope that Google Cloud Deploy will make it easier to implement full CI/CD pipelines. And we’re simply getting began! Keep tuned as we introduce thrilling new capabilities and options to Google Cloud Deploy within the months to come back.
