Docker is a powerful tool for application deployment, primarily due to its containerization capabilities. It allows developers to package applications along with their dependencies into containers, ensuring that they run consistently across different environments. This is particularly useful in resolving issues where code works on a developer’s machine but fails in testing or production environments ³.

The deployment process with Docker typically involves creating a Docker image using a Dockerfile, which contains all the necessary instructions to build the image. Once the image is created, it can be run as a container, providing an isolated environment for the application. This isolation helps in managing dependencies and configurations, making deployments faster and more efficient ²³.

Additionally, Docker supports various commands that facilitate the deployment process, such as docker build to create images and docker run to start containers. This streamlined workflow enhances productivity and reduces the complexity associated with traditional deployment methods ⁴.
