In this fast-paced book on the Docker open standards platform for developing, packaging and running portable distributed applications, Deepak Vorhadiscusses how to build, ship and run applications on any platform such as a PC, the cloud, data center or a virtual machine. He describes how to install and create Docker images. and the advantages off Docker containers. The remainder of the book is devoted to discussing using Docker with important software solutions. He begins by discussing using Docker with a traditional RDBMS using Oracle and MySQL. Next he moves on to NoSQL with chapter on MongoDB Cassandra, and Couchbase. Then he addresses the use of Docker in the Hadoop ecosystem with complete chapters on utilizing not only Hadoop, but Hive, HBase, Sqoop, Kafka, Solr and Spark.

Docker is an open standards platform for developing, packaging and running portable distributed applications. Using Docker, developers and sysadmins may build, ship and run applications on any platform such as a PC, the cloud, data center or a virtual machine. Getting all the required dependencies for a software application including the code, the runtime libraries, and the system tools and libraries is often a challenge when developing and running an application. Docker simplifies the application development and execution by packaging all the required software for an application including the dependencies into a single software unit called a Docker image that may be run on any platform and environment.

What makes Docker images unique and different from virtual appliances, which are also software images (virtual machine images), is that while each virtual machine image runs on a separate guest OS, the Docker images run within the same OS kernel. Docker software runs in an isolated environment called a Docker container that includes its own filesystem and environment variables. Docker containers are isolated from each other and from the underlying OS.

A Docker container for a software application includes all that is required to run the software, and files may be copied from the host OS to a Docker container if required. As an application could require other software to develop a linked application, Docker containers may be linked, which makes the environment variables and software from another Docker container available to a Docker container
