Delve into the most popular Docker features to explore the quick and robust way to build and deploy scalable applications
Docker is an open source containerization engine that offers a simple and faster way for developing and running software. It is one of the world’s best software container platforms. The use of containers in Docker makes it easy to develop, deploy and execute applications. If you're interested to gain practical knowledge on how to orchestrate and deploy scalable applications with Docker, then you should surely go for this Learning Path.
Packt’s Video Learning Paths are a series of individual video products put together in a logical and stepwise manner such that each video builds on the skills learned in the video before it.
The highlights of this Learning Path are:
- Develop containerized applications using Docker
- Explore advanced build options and image tags
- Deploy and test your Docker containers and put them to work in production
Let’s take a quick look at your learning journey. This Learning Path begins with setting up the Docker environment. You will be introduced to the basic Docker commands and how to work with images and containers. You'll then quickly learn how to write a Dockerfile, build an image from it, and then launch a container from that image. You'll also get hands-on experience with common Docker tasks such as pushing images to remote repositories, and using port mappings and the image caching layer during builds. You'll also explore how to run Docker services and learn how it can be used to run a group of related Docker containers. This Learning Path also covers advanced topics such as sharing data between containers, Docker services to run a group of related Docker containers etc.
You'll also gain knowledge on how you can contribute to the image repository by publishing different images. This will accustom you with the image building process and you'll be able to successfully run your programs within containers.
By the end of this Learning Path, you'll be confident in building and deploying your applications using Docker and have a clear understanding of techniques to get it running in production systems.
