Welcome to the first edition of Open Source Matters: our regular publication about the latest happenings in open source! Let’s dive into the news.

In Mattermost, our monitoring solution is continuously evolving to meet our scaling infrastructure needs. Our previous architecture used Prometheus federation and was perfect for our small/medium infrastructure size, but was not able to scale in the way we needed. This post will explain how we used Thanos and the Prometheus operator to scale our monitoring infrastructure and meet our long-term storage needs.

The value of Mattermost is significantly enhanced with third-party tool integrations and customization. Today, we are releasing the developer preview of a new Apps Framework for creating application integrations and customized workflows. The Apps Framework complements the existing ecosystem of plugins and allows apps to be written in any language and deployed with serverless hosting.

Mattermost v5.35 is generally available today. Incident Collaboration: Ad hoc tasks, stakeholder overview, and more (Cloud and E20 Edition). We are excited to release multiple new features for the Incident Collaboration product:

In the first article in this series, you learned how to set up your developer environment, the first step toward creating your very own Mattermost plugins. Take my word for it: Your first attempts at writing Mattermost plugins can be quite confusing. Where do you start? What do you have to do to get your first plugin up and running? At the end of this series, you’ll be well on your way to writing your own plugin.

Remote work has existed for decades as an alternative to the traditional in-office work environment. When it first became a viable option—people have been working remotely since the dawn of email in 1971 and before via telephone—distributed work was often met with trepidation by companies and employees alike. In recent years, however, working remotely, “working from home,” and other similar terms have become commonplace.

Finding the right information in Mattermost is critical to work smarter and be more productive. Searching in Mattermost now finds both relevant messages and files in your team’s conversation history. Search will return results for attachments that match the file name or contain matching text content within supported document types. File search is available today in Mattermost Cloud and in Mattermost Self-Managed v5.35 (available May 16), with mobile support coming soon.

The goal of this four-part series is to help you learn how to write your own Mattermost plugins for the first time. To kick things off, this article teaches you how to set up your developer environment. My test computer is a five-year-old laptop with an Intel i5 processor and 4GB of RAM. You need at least 30GB of hard disk for this project. Of course, you’ll also need an internet connection. We start with a freshly installed Ubuntu 20.04. You don’t need to install the desktop environment.

We’re excited to announce our partnership with Canonical to build a Mattermost Operator using the Juju Operator Lifecycle Manager (OLM), making it easy to install, integrate and upgrade Mattermost.

Mattermost v5.34 is generally available today. This new release includes the following new features (see changelog for more details): Enterprise Edition All Editions
