Rolling upgrades need to proceed in order and are the most demanding step of the process. One cannot continue a rolling upgrade until and unless previous updates to MySQL instances are running and ready. 4 Verify the cluster. 5. Enable client access to database proxies.
In this post, I hope to explore different forms of “testing in production”, when each form of testing is the most beneficial as well as how to test services in production in a safe way.
Knox, Pinterest’s open-source secret management service, now supports SPIFFE x509 identity documents as an authentication method. This update enables Knox to manage secrets in multi-tenant environments like Kubernetes.
India is a mobile-first country, with 71% of the population having only a mobile internet connection and accessing the internet only via mobile.
While working on a little PR for the Hugo doc site theme, I learned that if I needed to make changes to JS/CSS, I had to commit my changes in both unminified and minified versions. I have a habit to always look at the diffs at the time of staging and committing.
First, let me say thanks to mpdonadio for his tweet which helped me out of a composer ditch I couldn’t possibly get out of myself and to mixologic who provided some astonishing insight into this craziness. So I am testing the login flow for https://community.smartsheet.com .
As companies on-board to Kubernetes, one of their goals is to provide developers with an iteration and deployment experience that closely mirrors production.
We recently upgraded from PHP to Go for our Face Recognition API architecture. In this article we share why we made the move, how it’s radically improved performance, and some lessons learned along the way.
In the world of distributed systems, hosting and scaling dedicated game servers for online, multiplayer games presents some unique challenges.
Its been some time since I presented santiano.io first beta version at last MeasureCamp Bruxelles in 2017. With great feedback there and some time to test santiano.io features with my customers, I am now so happy to tell you. Now santiano.io V1.0.0 is live !
We’re pleased to announce that ACMEv2 and wildcard certificate support is live! With today’s new features we’re continuing to break down barriers for HTTPS adoption across the Web by making it even easier for every website to get and manage certificates.
Time in milliseconds; lower is better. SSR = Server-side rendered, CSR = Client-side rendered. Render time measured in CSR mode, rehydration time measured in SSR mode. Both flavors performed very well.
Let’s suppose we’re running an IT company employing programmers and testers. To give people a chance to get to know each other and relax a bit we’ve bought a ping-pong table and established following rules: So first either tester or programmer approaches the table.
The technological choices made at the beginning of a project or a company can very likely end up proving to be either inadequate or outright wrong a few years down the road.
TJ Holowaychuk, a long-time Nodist (from a Nodist colony?) who has contributed much to Node, finally abandoned Node in favour of Go. TJ writes:
In 2015, I stumbled on the golang BoltDB database library, and first used to save state in basic server-side applications. Then I stumbled on blevesearch, and it dawned on me. The most basic thing most databases offer is storage, and flexible search over stored data.
Conjur is an open source security service that integrates with popular tools to secure secrets, provide machine identity based authorization, and more. Running your own Conjur server gives you total control over the software.
Dr. Frankenstein’s monster is one of the most hated and misunderstood monsters of all time. Frankenstein brought his creation into the world without proper forethought or planning. He simply stitched various body parts together to form an uncontrollable abomination.
Nearly five months after the last release, we’re happy to announce that Caddy 0.10.11 is now available! This release brings service discovery for reverse proxying, reusable snippets to the Caddyfile, support for automatic HTTPS in a cluster, improved TLS management at scale, and much more.
For me, design means building, tearing down, and building again, over and over. To write the new versioning proposal, I built an prototype, vgo, to work through many subtle details. This post shows what it’s like to use vgo. You can download and try vgo today by running go get golang.org/x/vgo.
It’s an odd day for me, today. Russ and i have been meeting weekly since December, discussing what has evolved into the vgo prototype that he’s announced publicly today. There’s a lot to be excited about there:
Managing build time secrets can be a huge pain with docker. If you’ve built a docker image with private repositories, you might benefit from reading this. There are multiple solutions floating around the internet for this problem. We’ll start with the obviously bad ones and work our way up.
Someone: Did you hear that Facebook/Google uses a giant monorepo? WTF! Me: Yeah! It’s really convenient, don’t you think? Someone: That’s THE MOST RIDICULOUS THING I’ve ever heard.
API-first, or “decoupled”, architecture is quickly becoming the most popular way to create world class digital experiences. The pattern gives developers the flexibility to rapidly innovate, while ensuring future-proof builds that don’t require re-creating the entire CMS for new features.
Most software projects involving more than a few contributors end up with some process for having more than one person look at a piece of code before it gets shipped.
So testing, right? We should do it. The thing is, testing is hard, and good testing is reaaaaaaally hard, and tbh I’m pretty bad at testing. So I end up not testing my apps, and then I feel guilty about it, but I’ll stop you now: you can’t run guilt on Travis.
We’ve been running Kubernetes for deep learning research for over two years. While our largest-scale workloads manage bare cloud VMs directly, Kubernetes provides a fast iteration cycle, reasonable scalability, and a lack of boilerplate which makes it ideal for most of our experiments.
Twitter Lite uses Redux for state management and relies on code-splitting. However, Redux’s default API is not designed for applications that are incrementally-loaded during a user session. This post describes how I added support for incrementally loading the Redux modules in Twitter Lite.
We all know that unit tests help us to be sure that code works as we expected. And one of the metrics we can use with unit tests is a Code Coverage.
