Containerization has become a popular phenomenon in software development. Developers use this methodology to ease the process of sharing and running applications or software. Docker is a widely used platform that enables users to access services that allow OS-level virtualization for delivering software in containers. Read on to gain a deeper insight into how Docker plays a significant role in the area of software development via its registries, such as the Google Container Registry, Quay, Docker Hub, Docker registry by JFrog, etc.
What is a Docker Image?
There are numerous dependencies required for an application or software to be executed. A Docker image serves the purpose of a carrier to the multiple functionalities needed to run the application. It contains the libraries, back-end code, tools, and other related files. When a developer runs a Docker image, it creates an instance of one or many containers. These containers, in technological terms, are packages that work as a convenient medium for developers enabling them to not depend on any operating system for running applications, and tasks can be carried out independent of the environment where the work is being done. Containers are a great medium for continuous integration and a continuous delivery pipeline.
What is a Docker Registry?
There is a need to store Docker images. Therefore, a platform such as a Docker registry is required for this purpose. It is organized into repositories to hold Docker images under one umbrella. These registries offer multiple features that simplify Docker needs and allow for efficient Docker image management.
How a Docker Registry Proves To Be Useful?
A Docker registry consists of several repositories, which can be public or private. A public repository can be accessed by anybody on the platform, while a private repository can have access restrictions. The Docker images are organized into these repositories and are tagged. Tagging makes it easier for users to manage and easily identify Docker images.
Docker images can be managed well in a Docker registry, even if multiple teams are working on the same project. This is because the registries make organizations and teams capable of collaboration by making interaction and sharing convenient. A developer who may be in one part of the world can easily work in a team that may be working in another corner of the world.
Moreover, these registries allow for automated builds of containers. It is feasible for the developers as it saves a lot of time and helps negate any management issues. This way, organizations can make time for working towards further improvements and updates. Some registries also offer a caching feature that helps apply automated caching on the container builds by pulling images automatically onto the repositories to enable caching.
Furthermore, free versions of Docker registries also give an advantage to the developers to see if the registry is feasible for managing the Docker images systematically. Specific plans and premium packages are available to choose from.
Security is also an important factor when it comes to the management of Docker images. These images are vulnerable to security threats and risks. In order to avoid any security issues, access restrictions can be placed in accordance with the accessibility policy of an organization. The registries allow owners to select who can view their Docker repositories.
Moreover, they also have built-in security features along with image scanning. The authenticity and security of Docker images can be ensured this way before their distribution. In addition, it offers an autotest feature that allows the developer to run the application’s tests when the image has been built. It automatically stops the push if a test fails.
Docker Hub is the official container image registry provided by Docker. It contains over 100,000 images and further allows to push and pull images from other sources. Users and developers can also directly access code to build containers from other platforms like GitHub and BitBucket. It further makes it easy to manage Docker images by facilitating developers with some other options like webhooks which makes it possible to integrate even more services and platforms into their workflow. Like other registries, it too offers free access to public repositories, but alongside, it also allows a specific number of private repositories to be used without payment.
Ending Note
Hence, a Docker Registry is a solution to having better control over your Docker images and their management. It makes it possible for developers to make use of the automated and easy-to-use features to manage their Docker images in an orderly manner.
