Docker Clause Samples
Docker. Docker is a collection of platform as a service (PaaS) solutions that provide software in containers via OS-level virtualization. Among the several container technologies, Docker is extensively used and interoperable with all major providers of local operating systems and cloud computing platforms, and it has established a number of industry standards. Docker technology is not open source; however, it is available for free (under the Apache License 2.0). Furthermore, Docker has a large user base and an active community, and it has been embraced by many businesses. There is now an enormous database of Docker images accessible, as well as rich documentation to help developers throughout various Docker tasks. A Docker image is created by following the instructions in a text file called a Dockerfile. The Dockerfile also includes the container's primary command of execution or the path to a shell script containing the execution instructions. The image is composed of numerous layers, including a basic operating system layer as well as levels holding run times and configuration files. Containers can execute as standalone executables from the docker image. Figure 16 shows the difference between Docker and Virtualization Technology.
Docker. Docker[6] is an open-source project that automates the deployment of applications inside software containers. It is promoted by the company Docker, Inc. Docker provides an additional layer of abstraction and automation of operating-system-level virtualization on Windows and Linux. Docker uses the resource isolation features of the Linux kernel. Within OpenReq Docker will be used as one of the target containers to distribute the OpenReq platform. JUnit[7] is an open source unit test framework which uses annotations to identify methods that specify a test. A unit test is a piece of code written by a developer that executes a specific functionality in the code to be tested and asserts a certain behaviour or state. JUnit will be the main framework used for unit testing in the OpenReq development process. Git[8] is a version control system for tracking changes in computer files and coordinating work on those files among multiple people. It is primarily used for software development, but it can be used to keep track of changes in any files. Git supports rapid branching and merging, and includes specific tools for visualizing and navigating a non-linear development history. In Git, a core assumption is that a change will be merged more often than it is written, as it is passed around to various reviewers. In Git, branches are very lightweight: a branch is only a reference to one commit. With its parental commits, the full branch structure can be constructed. Being embedded in Tuleap and compatible with ▇▇▇▇▇▇▇, it has been chosen as the primary repository for OpenReq source code. The releases will be organized using the eclipse branching strategy [12].
