IS DOCKER AND KUBERNETES THE SAME DRIVER
The Tomcat application server and a database driver library file for database connection are installed in the second container. The database server and the necessary libraries and other components are contained in its first container. Each of these servers run on their own containers: one for the application server and another for the database server. When Pega Platform is installed, it requires the use of a web server and database server. If the image on the local disc is not the most recent, the Docker daemon pulls Docker images from Docker Hub otherwise, it pulls a local image from the disc and builds container images as requested by the client. In this diagram, Docker users communicate with the Docker via a command line interface (CLI) (client) that allows them to issue build, pull, push, and other Docker commands to the Docker daemon. The following list shows examples of popular container engine software: Repetitive jobs and tasks, which can be quickly handled with new containers.Existing applications that can be lifted and shifted into the latest cloud architectures.
IS DOCKER AND KUBERNETES THE SAME SOFTWARE
Software containers solve migration problems that can occur when an application moves from one environment to another environment.Ĭontainers encapsulate an application as a single bundle and other related binaries, libraries, configuration files, and any dependencies that are required for its execution. You can use containers to run a small microservice or large application.
These nodes, or Docker hosts, can be bare-metal servers or virtual machines. If you have Docker installed on a bunch of hosts (different operating systems), you can leverage Kubernetes. Kubernetes turns it up to 11, so to speak.
When software is developed and tested in one computing environment and then migrated to another, issues might arise if the supporting software environment is not identical (for example, when software is developed on a laptop and moved to a virtual machine (VM) or Linux to a Windows operating system). Docker is what enables us to run, create and manage containers on a single operating system. Robotic Process Automation Design Patterns
