Docker is an open-source containerization tool for deploying and running applications. Docker containers encapsulate an application's code, dependencies, and configuration files, allowing for consistent and reliable deployment across different environments.
In the context of federated learning, Docker containers can be used to package the entire client and server application, including all the necessary dependencies, and then deployed on various devices such as edge devices, cloud servers, or even on-premises servers.
In Flower, Docker containers are used to containerize various applications like SuperLink, SuperNode, and SuperExec. Flower's Docker images allow users to quickly get Flower up and running, reducing the time and effort required to set up and configure the necessary software and dependencies.
