What is a Docker compose?

Docker Compose is a tool that was developed to help define and share multi-container applications. With Compose, we can create a YAML file to define the services and with a single command, can spin everything up or tear it all down.

What is Docker container?

Docker containers are the lightweight alternatives of the virtual machine. It allows developers to package up the application with all its libraries and dependencies, and ship it as a single package. The advantage of using a docker container is that you don't need to allocate any RAM and disk space for the applications. It automatically generates storage and space according to the application requirement.

Why do we use Docker?

There are the following reasons to use Docker -. Docker allows us to easily install and run software without worrying about setup or dependencies. Developers use Docker to eliminate machine problems, i.e. " but code is worked on my laptop .". when working on code together with co-workers.

What are the disadvantages of Docker?

1. Overview

In this article, we take a look at another well-established platform specific API — Java API Client for Docker.

3. Using the Docker Client

DockerClient is where we can establish a connection between a Docker engine/daemon and our application.

4. Container Management

The API allows us a variety of choices about container management. Let's look at each one of them.

5. Image Management

There are a few applicable commands we are given to manage image operations.

6. Volume Management

If Java projects need to interact with Docker for volumes, we should also take into account this section. Briefly, we look at the fundamental techniques of volumes provided by the Docker Java API.

8. Conclusion

In this extensive tutorial, we explored the various diverse functionality of the Java Docker API Client, along with several implementation approaches for deployment and management scenarios.

What is a base image in Docker?

This is what we call the base-image. The base image is the foundation of the new image you are about the build for your Java application. The base image you choose is essential because it allows you to utilize everything available in this image. However, this comes at a price. When a base image has a vulnerability, you will inherit this in your newly created image.
