Mirantis Kubernetes Engine Manufacturing Reviews & Insights

Docker is everywhere, there just isn't a server on an application which is not present in Docker. It forms the integral part of the whole infra for us. The beauty of Docker comes from its amazing quality of being robust, easy to start and very easy to blow it off completely. It's the most powerful tool which just does magic for us.

For CI/CD it is the best tool to use. If you want to manage an infra where there are millions of machines needed you need to start using Docker if you are not.

Docker is used by most of our teams as part of their development and deployment practice. For development, it enables engineers to build applications in the same environment without worrying about local configuration issues. Nearly all of our CI/CD and infrastructure runs in Docker containers as well, which makes debugging production issues (especially around deployment) as simple as pulling down the right image and poking at it locally.

Docker is the best widely-used solution for isolated development environments and predictable deployments. However, for teams that work with only one specific technology stack, using Docker for local development can introduce more complexity. It shines when teams have to move between many different types of projects, but is "overkill" for a single application with minimal dependencies.

We use Docker as part of a rapid deployment project that allows a service to be easily deployed directly onto VMs automatically during staging and production. It makes the management of the VM a parallel task to the deploy process. Traditionally the provision of a VM would be intertwined with the deploy process and containerization allows for these things to be decoupled.

Docker is great for staging and quickly deploying small to medium projects. With larger projects, it can become a significant challenge to manage all of the containers used for multiple microservices, keeping them up to date, secure and portable to other platforms. One of the goals of Docker is to allow the macro service to be platform agnostic and this can sometimes be more of a challenge than its long-term benefit.
