Many moons ago, Jonny coined the term “Stelligentsia” to refer to our small, merry band of technologists at the time. Times have changed and the team has grown by a factor of 10 but we strive to live up to the name as all things DevOps and AWS continues to evolve. We find the best way to do this is Read more…
Deploying SpringBoot microservices into ECS with CloudFormation Read more…
In the last post we created two basic applications each with a basic shell script to automate deploying them into AWS. In this post we will continue refactoring those deploy scripts to work on getting them setup using a common pipeline. We are aiming to have the pipeline executable code configured through metadata allowing us Read more…
In this blog post, we will cover developing nix packages and testing them in docker. We will set up a container with the proper environment to build nix packages, and then we will test build existing packages from the nixpkgs repo. This lays the foundation for using docker to test your own nix packages. First, a quick introduction Read more…
We often overlook similarities between new CD Pipeline code we’re writing today and code we’ve already written. In addition, we might sometimes rely on the ‘copy, paste, then modify’ approach to make quick work of CD Pipelines supporting similar application architectures. Despite the short-term gains, what often results is code sprawl and maintenance headaches. This blog post series is aimed at helping to Read more…
In this first post of a series exploring containerized CI solutions, I’m going to be addressing the CI tool with the largest market share in the space: Jenkins. Whether you’re already running Jenkins in a more traditional virtualized or bare metal environment, or if you’re using another CI tool entirely, I hope to show you Read more…
In this episode, we cover recent DevOps in AWS news and speak about the AWS EC2 Container Service (ECS), EC2 Container Register (ECR), HashiCorp Consul, AWS CodePipeline, and other tools to provide solutions for customers Read more…
In this three-part series, I’ll explain ServerSpec infrastructure testing and how we use it at Stelligent, provide some concrete examples demonstrating how we use it at Stelligent, and discuss how Stelligent has extended Serverspec with custom AWS resources and matchers. We will also walk through writing some new matchers for an AWS resource. If you’re Read more…
Linux containers are a relatively new abstraction framework with exciting implications for Continuous Integration and Continuous Delivery patterns. They allow appropriately designed applications to be tested, validated, and deployed in an immutable fashion at much greater speed than with traditional virtual machines. When it comes to production use however, an orchestration framework is desirable to maintain Read more…
At Stelligent, we put a strong focus on education and so I wanted to share some books that have been popular within our team. Today we explore the world of microservices with “Building Microservices” by Sam Newman. Microservices are an approach to distributed systems that promotes the use of small independent services within a software Read more…
