Docker has long been the simplest way to run containers. Developers start with a docker-compose.yml file, run docker compose up, and get things running fast. As teams grow and workloads expand into Kubernetes and integrate into cloud services, simplicity fades. Kubernetes has become the operating system of the cloud, but your clusters rarely live in...

Cloud platforms have come a long way since Heroku first set out to empower developers. Today’s cloud native development demands even greater flexibility, openness, and scalability. A fun fact about Heroku is that we use trees to denote the generation of the platform technology stack (aka version). In the tradition of Aspen, Bamboo, and Cedar, […] The post Planting New…

In a previous blog post—A Simple Kubernetes Admission Webhook—I discussed the process of creating a Kubernetes webhook without relying on Kubebuilder. At Slack, we use this webhook for various tasks, like helping us support long-lived Pods (see Supporting Long-Lived Pods), and today, I delve once more into the topic of long-lived Pods, focusing on our…

Cron scripts are responsible for critical Slack functionality. They ensure reminders execute on time, email notifications are sent, and databases are cleaned up, among other things. Over the years, both the number of cron scripts and the amount of data these scripts process have increased. While generally these cron scripts executed as expected, over time…

In 2006, British mathematician Clive Humby declared “data is the new oil.”Like oil, data in raw form — sans insights and analysis has limited use. To harness the potential on data, organizations are constantly seeking ways to leverage their data to gain a competitive edge. This is where data science comes into play. CRED has evolved from a single product…

Kubernetes is a very popular open-source container orchestration system for deploying, scaling, and updating your software, as well as automatically recovering from failures. If your code can be packaged into a container, e.g. via Docker, then it can run on Kubernetes, or k8s for short (which is sometimes pronounced ‘kates’ and refers to the 8 letters between the first and…

At Groupon, we are in the process of migrating our app workloads to AWS EKS. As part of the migration, we are also in the process of re-architecting our services to make them cloud & Kubernetes optimised. In this article, we will focus on the impact of cloud migration on Varnish caching at Groupon. For the uninitiated, Varnish is a…

While adding a recent feature to our Kubernetes compute platform, we had the need to mutate newly-created pods based on annotations set by users. The mutation needed to follow simple business rules, and didn’t need to keep track of any state. Surely there must be a canonical solution to this simple problem? Well, sort of.…

Containers, specifically Docker, are all the rage. Most DevOps setups feature Docker somewhere in the CI pipeline. This likely means that any build environment you look at, will be using a container solution such as Docker. These build environments need to take untrusted user-supplied code and execute it. It makes sense to try and securely […] The post A House…

Everyone gets the same set of tools Something that had long puzzled me was the question “Why do some people [in the organisation] have root, and others do not?” It seemed to me that the reason the sysadmins had the root passwords, and everyone else had to raise tickets, was a tooling problem. Giving everyone […]
