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.

Ansible is a configuration management tool that helps you automatically deploy, manage, and configure software on your hosts. By turning manual workflows into automated processes, you can quicken your deployment lifecycle and ensure that all hosts are equipped with the proper configurations and tools. The Datadog collection is now available in both Ansible Galaxy and Ansible Automation Hub.

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.
