As you move more towards continuous testing, it becomes important to be able to execute your automated tests rapidly in multiple environments. Docker is perfect for this, providing a simple way to execute your tests on any system, against any environment. Selenified works perfectly inside a Docker container, allowing functional tests to be easily integrated […]
As part of the project I’m currently engaged on, my team is writing automated tests for an application which has a web interface, and also 2 mobile apps, one for Android, and one for iOS. As part of the project, we’ve built a test automation pipeline which runs our tests against our application to ensure […]
Deploying and running applications in Containers is one of the hottest trends in DevOps and IT today. Docker, a containerization platform that lets users easily package, deploy, and manage their applications within containers, is principally responsible for bringing containers to the mainstream. This article provides information about what containers are, their relationship with DevOps, and […]
Last month I talked about the need for Docker-aware configuration management (CM) tools to effectively build and test containers in a CI/CD pipeline. The goal is to not install any extra tooling inside of the docker container that gets published for production use; not sshd, nor any CM tooling. This technical post documents the major […]
Last month, I discussed using Docker containers because they increase confidence in our deployed infrastructure. Now that we’ve decided to use this new tool, we need to learn how to use it well. After spending some more time with containers, I’d like to dive deeper into their benefits and the process of building (and rebuilding […]
Hey DevOps Engineers, Docker is ready! I started getting into Docker just under a year ago. It obviously had promise, but I couldn’t find many people using it successfully. Since then Docker has matured, and I’ve been recommending it to everyone doing CI/CD web-services. When the IT services industry first went to the dynamic virtual […]
Docker Inside Your Pipeline Docker has many applications in a modern CI/CD pipeline that make it a natural fit. In particular I use it for build containers and integrations testing. With docker you open up several capabilities that are not normally available to you with CI. First off, you can change your build environment without […]
Docker is amazing. These thin containers are much more resource efficient than full virtual machines, and I rarely need to have an OS that is much different from my host OS. What I really want to do is put up generic environment walls so that my application stack is happy, but not so separate that […]
A real-world look at building a DevOps pipeline using Circle CI.
Explore what containers are all about and the various ways you can leverage them to improve your software development, test, and deployment process.
