Integrating with Your Organization’s Workflows

In this chapter, we’ll show you how to integrate your software development pipeline with external systems that your organization might use to deliver continuous integration/continuous delivery (CI/CD).

For this chapter, we’ll use third-party source code management systems through a Cloud Build trigger. After a successful test execution, we’ll automate Cloud Deploy promotion and integrate Cloud Deploy approval with third-party workflow management tools using Cloud Pub/Sub.

This chapter includes references to third-party tools from non-Google vendors. Examples of third-party tools include source control repositories such as GitHub, GitLab, and BitBucket, and project-management tools such as Jira, ServiceNow, Remedy, and others. You can use these applications along with your CI/CD pipelines to support capabilities such as approval workflows and repository interactions.

Technical requirements

To perform the tasks in this chapter, you’ll need a Google Cloud project with billing or a free trial enabled. You can reuse the project you’ve been using throughout this book. In addition to these items, and what you’ve already enabled in previous chapters, you’ll need the following:

An account on gitlab.com
A repository on gitlab.com
The Google Pub/Sub API enabled

The source code for this chapter is available in this book’s GitHub repository at https://github.com/PacktPublishing/Secure-Continuous-Delivery-on-Google-Cloud.

For our first look at third-party integration, we’ll connect a Cloud Build trigger to a non-Google source code repository: GitLab.

Connecting a Cloud Build trigger to a third-party repository

Other chapters of this book use GitHub as a source code repository. Although GitHub is very popular, there are other top-tier repository providers out there, such as GitLab and BitBucket. This chapter’s example uses GitLab to illustrate a different integration than we’ve used in previous chapters.

To use GitLab as a source repository, there are three main steps:

Create a host connection.
Create a link to the repository.
Create a Cloud Build trigger.

These three steps will be expanded upon in the following sections, starting with connecting to GitLab.

Creating a host connection to GitLab

Follow these steps to create a host connection to GitLab. This procedure assumes you have a GitLab account. These steps create two tokens. The first provides full API access, while the second provides API read-only access:

In GitLab, create an api personal access token.

Integrating Cloud Deploy with automated testing

Automated testing is an important part of a source-to-prod workflow. You can use deployment verification after any completed deployment to confirm that your deployment works as expected.

In addition to deployment verification, you can use deploy hooks to reach out to local or remote resources. Sometimes, you need to connect to a third-party service after deployment has been completed. Post-deploy hooks make that possible. As with verification, post-deploy hooks run from a user-defined container. Unlike verification, deploy hooks are intended for actions that only have an effect when they’re run for the first time, for a given release.

In the example in this section, the delivery pipeline uses a post-deploy hook to call an API from the Google PageSpeed Insights (PSI) tool. PSI assesses your website’s user experience across mobile and desktop environments while also providing suggestions to improve performance. This...

Integrating Cloud Deploy approval with third-party workflow management tools

Cloud Deploy uses Pub/Sub to communicate with other applications, including applications for third-party providers.

Pub/Sub is often used in event-driven programming. With Pub/Sub, an application publishes information (messages) to a topic, and other applications subscribe to that topic to receive the messages. Those other applications can use these messages to invoke actions. In this section, we’ll show you how to create a topic and subscribe to that topic via Pub/Sub.

Cloud Deploy publishes messages to the topics listed in the following table:

Summary

In this chapter, we examined how to expand the capabilities of a CI/CD pipeline more in line with real-world needs. You learned how to create a Cloud Build trigger on an external repository, integrate a Cloud Deploy delivery pipeline with automated testing, and use Pub/Sub to initiate an approval workflow with a third-party workflow management tool.

You might not need these more advanced topics immediately, but once your DevOps pipeline is running, you could find these helpful when it comes to improving the overall experience.

Connecting the pipeline to third-party tools extends the range of what’s possible. Many different third-party capabilities, such as Agile project management, metrics, source code repositories, and alerting tools, exist outside of the native capabilities of Google’s first-party software.

This chapter also touched on some of the advanced first-party options in Cloud Deploy, such as automation. These advanced first-party options,...
