Docker Virtualization, known for its simple and convenient way of deploying applications is the best-to-go option for every developer and organisation. Also, it offers the flexibility to run multiple applications on the provided host or directly executing the container within the host environment per se. Here, in this article, a basic working environment will be created by setting Nginx as a web server and MySQL as the database, all within separate Docker containers.
Docker offers a set of PaaS (Platform as a Service) works using its container-based technology to address the limitations of Virtualization that had been experienced over the years now. This article will start with the basic procedure on how to verify your access to Docker Hub and thereby to search images using the Docker commands followed by searching the Nginx official image for demonstration purpose.
Docker, an open-source container-based technology, aims to streamline and manage workload via distributed applications. In simplest form, it’s just another form of Virtualization and the difference lies in the fact that Docker outranks the benefits of the traditional Virtualization almost in every aspect. Here, you will learn about the installation process of Docker on Ubuntu 18.04 system.
This article will walk-you through what is Docker; how it works, why we opt Docker instead of Virtualization, what are the aspects and benefits that stand out Container technology from traditional VMs and so forth. Further, a list of important Docker terminologies have been explained for the benefit of Docker installation and usage.
The CI/CD pipeline, known as the Build Pipeline works on granting better visibility over the automated steps during the CI/CD process. For example, it makes use of build servers like Jenkins, Travis CI and TeamCity to achieve visibility over all the automated phases, and fetches the status and info in the UI form. This way of tracking the progress of automated steps is crucial so as to ensure the fine-workings of the phases and the expected outcome.
The CI being the process within the process of DevOps practice plays a vital part from building the source code until delivering the deployment-ready software package. Nonetheless, in this article, you will see what makes the Continuous Integration so remarkable; the different stages involved, its benefits and the role it plays in the entire DevOps process.
