Docker

Introduction of Docker:

Docker is an open platform for developing, shipping and running applications. It is a software platform that allows you to build, test and deploy application quickly.

Docker software development providing a standardized way to package, distribution, and deploy applications within containers. Which encapsulate everything needed to run the application, including the code, runtime system tool, library, setting etc. Docker ensure consistency across all the different environment, from development to production environment.

Docker simplifies the process of deploying applications by avoding the “It working on my machine” problem.

Introduction of Docker container:

Docker provides the ability to package and run applications in a loosely isolated environment called a container.

Container is a standard unit of software the packages code and dependency so the application run quick and reliably form one environment to another.

Container image become containers at runtime, and in the case of Docker, container are created when the image run on Docker engine.

Docker container are support Linux, windows, cloud etc.

In below guide, will explore how to use Docker with .Net application, Integration, support framework etc.

Configuring Docker with .Net:

· First, you need to Install Docker on your development machine. Docker Desktop is available Windows, macOS and Linux, providing different type of interface for managing containers.

· Create a Dockerfile in your .Net project directory to define the container environment. Define the base image, dependencies, build steps and running the runtime settings. Below is basic example for .Net applications. Below is the basic example for .Net applications.

· Use the Docker CLI to build the Docker image from Dockerfile. Run the below command in the project directory.

· Once the image is build, you can run a Docker container based on that image using below command.

Integration and Use in .Net projects:

· Utilize the Docker compose the define and run multi-container Docker applications. Define your applications service, dependencies in your docker.yaml file.

· Integrate Docker in into CI/CD pipeline to automate the build, test and deployment process.

Support Framework:

· .Net core: version 2.x, 3x and 5.x

· .Net framework: Version 4.x

· .Net 5/6: Latest version.

Advantage of Docker with .Net:

· Docker container ensure consistence in across different environments, enabling seamless deployment.

· Container encapsulate applications and their dependency, avoding the conflicts with the host system.

· Docker facilitates easy scaling of .Net applications using container.

· Docker simplified the deployment process by providing standardize packing format and automate deployment workflow.

· Docker promotes resource efficient by running the lightweight, isolate container, reducing overhead and optimizing resource application.

Introduction of Image:

A running container uses an isolated file system provided by image. The image must contain everything needed to run the application like all dependencies, configuration etc. this image also contains other configuration for container like environment variable, default command etc.

Conclusion:

Docker is a powerful solution for packaging, distributing and running the application in container. By following the configuration guidelines and integrating Docker into your .Net project.

You can easily define your development and deployment workflow, ensuring consistency and efficiency across different environment.
