* The CLI uses Docker APIs to control or interact with the Docker daemon through scripting or direct CLI commands. * Docker CLI – A command-line interface client for Docker. * APIs which specify interfaces that programs can use to talk to and instruct the Docker daemon. * A server with a long-running persistent daemon process called “dockerd” that manages containers. Since Docker Engine is an open-source containerization technology for building and containerizing applications, so Docker Engine acts as a client-server application with the following role: So we can easily share the docker containers to everyone while we’re on the work. That’s why we don’t need to rely on what is currently installed on the machine. So you can run many containers simultaneously on the same node, since docker containers are lightweight and having everything needed to run the application. It will significantly reduce the time or delay between writing code and running it in production environments.ĭocker have a loosely isolated environment called a container which provides the ability to package and run an application. We can take all advantage with Docker’s methodologies, like for deploying code, shipping and testing applications quickly. You can also use Docker to manage the infrastructure in the same place where you manage your applications. So, you can deliver your software more quickly. Docker is an open-source and free containerization platform for developing, testing, shipping and running applications, which allow you to separate your applications from your infrastructure.
