Docker vs Snap CI: What are the differences?
Key Differences between Docker and Snap CI
1. Docker: Containerization Platform Docker is a containerization platform that allows you to package an application and its dependencies into a standardized unit called a container. These containers are isolated environments that provide consistency and portability, enabling applications to run seamlessly across different operating systems and environments.
2. Snap CI: Continuous Integration and Deployment Tool Snap CI, on the other hand, is a continuous integration and deployment tool that helps automate the process of building, testing, and deploying software. It provides a pipeline-based workflow that allows developers to define their build and deployment stages, and seamlessly integrate with other tools and services.
3. Docker: Operating System Level Virtualization Docker uses operating system-level virtualization to run containers. It shares the host operating system's kernel and resources, making it lightweight and efficient. Each container runs in isolation, providing process-level separation and resource control, while still sharing the underlying operating system.
4. Snap CI: Code Execution Environment Snap CI provides a dedicated execution environment for running build and deployment jobs. It allows developers to define these jobs using a YAML configuration file, specifying the steps and dependencies required. Each job runs in its own isolated environment, ensuring consistent and reproducible results.
5. Docker: Infrastructure Agnostic Docker allows applications to be run on any infrastructure that supports Docker, such as physical servers, virtual machines, or cloud-based platforms. This agnostic approach provides flexibility in deployment options and makes it easier to manage and scale applications.
6. Snap CI: Integrated CI/CD Platform Snap CI offers an integrated CI/CD platform, providing a seamless end-to-end solution for building, testing, and deploying applications. It simplifies the process of setting up and managing the various stages of software delivery, reducing the need for manual intervention and improving overall development productivity.
In Summary, Docker is a containerization platform that provides standardized units called containers for running applications across different environments, while Snap CI is a CI/CD tool focused on automating the build and deployment process in a pipeline-based workflow.
lxd/lxc and Docker aren't congruent so this comparison needs a more detailed look; but in short I can say: the lxd-integrated administration of storage including zfs with its snapshot capabilities as well as the system container (multi-process) approach of lxc vs. the limited single-process container approach of Docker is the main reason I chose lxd over Docker.
