Getting Started with Docker and Docker Compose
With an ever-growing demand for data pipelines, storage and transformation, software that has been developed towards improving a programmer’s efficiency has been on the rise. Docker is a one-stop software housing containers that have libraries, packages, system, runtime tools and code. It enables data experts to run and deploy applications into any environment. As an open-source option, it makes the software attractive among beginners and start-ups seeking to deploy and distribute applications.
Features of Docker
As an open-source software, Docker relies heavily on key features such as:
Isolation
Containers housing information run independently, providing a secure and consistent environment for applications, eliminating conflicts between them. It also provides service-oriented tasks, simplifying distribution, calling and debugging.
Portability
Docker can run on any system that has the software installed, regardless of the underlying operating system.
Open-Source Platform
Prompts users to choose which technology, i.e. Amazon, to complete a task. As such, its features are attractive to beginner and lone developers dependent on Docker toolchains.
Efficient Life Cycle
By eliminating time lost between writing code, having it tested and deployment, Docker not only saves users resources but also motivates individuals to embrace more tasks.
Scalability
Provides developers flexibility as Docker containers are lightweight, making them attractive in handling dynamic workload fluctuating between different deployed applications
Image Management
Serve as a blueprint to developers and data experts when building applications or making changes to existing projects. New images stored in the Dockerfile contain a set of instructions sent to Docker on how to create an image. A registry housed in Docker hosts the Dockerfiles for future use.
Volume Management
Due to the numerous projects or large quantities of data saved and processed in Docker, the system ensures persistent data storage, availability of data logs and containers are stopped or removed while processing takes place.
Docker Compose
It’s a tool used to run multi-container applications. By scaling down production, the tool not only supports the streamlining of tasks but also manages Docker application stores in numerous containers. Docker runs applications in single container units, while Docker Compose specialises in running applications that use multiple containers.
