What does the docker process look like?

Docker is a popular open source containerization platform that can run applications in different operating systems. Its process can be divided into the following steps:

1. Installing Docker

First, the Docker platform needs to be installed on the device. The corresponding software can be downloaded from the official website and installed according to different operating systems.

2. Creating Docker images

Docker images are the building blocks of applications. The common way to create an image in Docker is to build from a base image. The base image can be a standard image in the official library or a self-defined image.

The process of creating an image includes writing a script to install or run the application, installing the required libraries and dependencies, and packaging these files into a Docker image.

3. Run the Docker container

After building an image, you can start the application by running the Docker container. When starting a container, you need to specify the image and container name to use.

Docker will automatically match the container with the parameters specified in the image and start the container. When running a container, you can specify some additional parameters to run the application in a specified environment, such as port number settings.

4. Using Docker Containers

Once the container is running, you can start running applications using Docker. Containers can be managed in common ways, such as viewing the status of the container, restarting the container, and deleting the container.

When running an application in a container, you also need to pay attention to the application's logs and configuration files to ensure that the application runs correctly.

Summary:

This is the process of Docker. As Docker continues to evolve, it has become an essential tool for developers, testers, and DevOps engineers. It can simplify the process of application development, testing and deployment, making the entire process simpler, more flexible and more efficient.
