Here at incident.io, we provide a Slack-based incident response tool. The product is powered by a monolithic Go backend service, serving an API that powers Slack interactions, serves an API for our web dashboard, and runs background jobs that help run our customers incidents. Incidents are high-stakes, and we want to know when something has gone wrong. One of the tools we use is Sentry, which is where our Go backend send its errors.
Go, an open-source programming language backed by Google, makes it easy to build simple, reliable, and efficient software. Go’s efficiency with network servers and its friendly syntax make it a useful alternative to Node.js. All network applications need well-tested features, and those developed in Go are no different. In this tutorial, we will be building and testing a simple Go blog.
Go, often referred to as Golang, is a popular programming language built by Google. Its design and structure help you write efficient, reliable, and high-performing programs. Often used for web servers and rest APIs, Go offers the same performance as other low-level languages like C++ while also making sure the language itself is easy to understand with a good development experience.
As of yesterday, the team behind Go has released a new version 1.18 with some significant changes to the language. Those of you who want to start using these new features are in luck: you can do it right away on Platform.sh. If you’re already using Go on Platform.sh, you can upgrade by changing the number in the type key of your app configuration. In your.platform.app.yaml file: If you’re not yet using Go for your project, now’s a great time to give Go a try.
We are going to deploy a Go application directly from your repo to AWS with Cloud 66. Any application using any language on any framework can be deployed with Cloud 66 as long as it has a Dockerfile. Note: Rails applications are exceptions as we deploy them natively. If your application does not have a Dockerfile, we will suggest one for you based on your code. However, we would recommend reviewing what we have suggested and making sure the Dockerfile meets your requirements.
While Go provides a testing package and a go test command, the former only offers basic testing capabilities. The package also has some drawbacks, such as missing assertions and increasing repetition with large-scale tests. As a result, several Go testing frameworks have been created to augment it. Go testing frameworks consist of tools and resources for creating and designing tests. Some of these frameworks incorporate the testing package and go test command, while others take a different approach.
We've gone through many iterations of ways to build, deploy and distribute applications written in Go at Cloud 66. Unlike Rails, Go applications can be web applications, daemons or CLIs and therefore have different requirements. I'll share some of what we've learned with you in this post.
At incident.io, we're acutely aware that we handle incredibly sensitive data on behalf of our customers. Moving fast and breaking things is all well and good, but keeping our customer data safe isn't something we can compromise on. We run incident.io as a multi-tenant application, which means we have a single database (and a single application).
We recently announced the release of our RemoteWrite SDK to support custom metrics from applications using several different languages – The first SDKs allow shipping of metrics from Golang (Go), Python, Java, Node.js, and.NET. This tutorial will cover the Golang SDK. The SDKs cover not just Logz.io, but can be used by any platform that supports the Prometheus remote write endpoint.
