This month, we’re focused on sharing a more comprehensive picture of our reliability and availability. We experienced 6 extended incidents, 2 of which were due to an upstream third party. While we always want to be transparent with our performance against our stated goals, it’s crucial to note that, while they lasted 60 minutes or longer, the impact of these August incidents on our business operations was relatively minimal.
A Docker container is a portable software package that holds an application’s code, necessary dependencies, and environment settings in a lightweight, standalone, and easily runnable form. When running an application in Docker, you might need to perform some analysis or troubleshooting to diagnose and fix errors. Rather than recreating the environment and testing it separately, it is often easier to SSH into the Docker container to check on its health.
This post was written with valuable contributions from Michael Webster, Kira Muhlbauer, Tim Cheung, and Ryan Hamilton. Remember the advent of the internet in the 90s? Mobile in the 2010s? Both seemed overhyped at the start, yet in each case, fast-moving, smart teams were able to take these new technologies at their nascent stage and experiment to transform their businesses. This is the moment we’re in with artificial intelligence. The technology is here.
This short tutorial demonstrates how you can work on data stored on your own infrastructure or in hybrid cloud CI/CD environments using CircleCI’s shared workspaces functionality — without having to configure VPNs, SSH tunnels, or other additional infrastructure.
Version control is a system for tracking and managing changes to a software project over time. It provides a structured way to document modifications, ensuring that every alteration is recorded along with details such as who made the change and when it occurred. This history allows multiple team members to work on the same project without overwriting each other’s work and to easily revert to previous versions of the project when necessary.
Effective user experience (UX) design is a key factor in creating compelling software products. UX considers the quality of interaction that users have with a product and takes the user’s point of view as the most sacred thing in software and product design. A great UX includes accessibility, which ensures that software is inclusive and usable by the widest possible audience.
Most modern infrastructure architectures are complex to deploy, involving many parts. Despite the benefits of automation, many teams still chose to configure their architecture manually, carried out by a deployment expert or, in some cases, teams of deployment engineers. Manual configurations open up the door for human error. While DevOps is very useful in developing and deploying software, using Git combined with CI/CD is useful beyond the world of software engineering.
At Circle, our traditional approach to Kubernetes (k8s) deployments likely looks familiar to many of you: Run the workflow, create the image, build the Helm chart and deliver it to k8s. At that point, k8s takes over with its rolling update. This method gets the job done, but we knew it wasn’t ideal. Limited support for canary releases and the need for time-consuming error monitoring and manual rollbacks added friction and risk to our release processes.
Containers and microservices have revolutionized the way applications are deployed on the cloud. Since its launch in 2014, Kubernetes has become a de-facto standard as a container orchestration tool. Helm is a package manager for Kubernetes that makes it easy to install and manage applications on your Kubernetes cluster. One of the benefits of using Helm is that it allows you to package all of the components required to run an application into a single, versioned artifact called a Helm chart.
