Docker is an open source platform for developing, delivering, and running applications. Docker uses containerization technology to package applications into an independent running environment, making application delivery and deployment easier and more efficient. For developers who use Docker, the first thing they need to know is which versions of Linux operating systems Docker supports.
Currently, the Linux operating system versions supported by Docker include the following:
- Ubuntu
Ubuntu is one of the most popular Linux distributions , is also one of the operating systems recommended in Docker’s official documentation. The latest version of Docker already supports the Ubuntu 20.04 LTS operating system, as well as Ubuntu 18.04 LTS and Ubuntu 16.04 LTS.
- Fedora
Fedora is a Linux-based operating system launched by Red Hat. Docker official documentation shows that Docker supports Fedora 31 and above.
- CentOS
CentOS is one of the enterprise-level Linux operating systems and one of the operating systems recommended in Docker’s official documentation. Docker supports CentOS 7 and above.
- Debian
Debian is a popular Linux distribution and one of the supported operating systems listed in the official Docker documentation. Docker supports Debian 10 and above.
- Red Hat Enterprise Linux
Red Hat Enterprise Linux is a commercial-grade operating system supported and serviced by Red Hat. Docker can be deployed and used on Red Hat Enterprise Linux.
- Oracle Linux
Oracle Linux is a Linux distribution launched by Oracle Corporation. Docker official documentation states that Docker supports Oracle Linux 7 and above.
It should be noted that since the essence of Docker is to use the namespace isolation technology of the Linux kernel to implement containerization, in addition to the Linux operating system recommended by official documents, other Linux distributions may also support Docker. But this requires developers to conduct their own testing.
In general, Docker supports many Linux operating system versions, and they are constantly being updated and improved. If you are using Docker for application development and deployment, it is recommended to choose the aforementioned officially recommended operating system version.
The above is the detailed content of Let's talk about which versions of Linux systems Docker supports. For more information, please follow other related articles on the PHP Chinese website!

The ways Docker can simplify development and operation and maintenance processes include: 1) providing a consistent environment to ensure that applications run consistently in different environments; 2) optimizing application deployment through Dockerfile and image building; 3) using DockerCompose to manage multiple services. Docker implements these functions through containerization technology, but during use, you need to pay attention to common problems such as image construction, container startup and network configuration, and improve performance through image optimization and resource management.

The relationship between Docker and Kubernetes is: Docker is used to package applications, and Kubernetes is used to orchestrate and manage containers. 1.Docker simplifies application packaging and distribution through container technology. 2. Kubernetes manages containers to ensure high availability and scalability. They are used in combination to improve application deployment and management efficiency.

Docker solves the problem of consistency in software running in different environments through container technology. Its development history has promoted the evolution of the cloud computing ecosystem from 2013 to the present. Docker uses Linux kernel technology to achieve process isolation and resource limitation, improving the portability of applications. In development and deployment, Docker improves resource utilization and deployment speed, supports DevOps and microservice architectures, but also faces challenges in image management, security and container orchestration.

Docker and virtual machines have their own advantages and disadvantages, and the choice should be based on specific needs. 1.Docker is lightweight and fast, suitable for microservices and CI/CD, fast startup and low resource utilization. 2. Virtual machines provide high isolation and multi-operating system support, but they consume a lot of resources and slow startup.

The core concept of Docker architecture is containers and mirrors: 1. Mirrors are the blueprint of containers, including applications and their dependencies. 2. Containers are running instances of images and are created based on images. 3. The mirror consists of multiple read-only layers, and the writable layer is added when the container is running. 4. Implement resource isolation and management through Linux namespace and control groups.

Docker simplifies the construction, deployment and operation of applications through containerization technology. 1) Docker is an open source platform that uses container technology to package applications and their dependencies to ensure cross-environment consistency. 2) Mirrors and containers are the core of Docker. The mirror is the executable package of the application and the container is the running instance of the image. 3) Basic usage of Docker is like running an Nginx server, and advanced usage is like using DockerCompose to manage multi-container applications. 4) Common errors include image download failure and container startup failure, and debugging skills include viewing logs and checking ports. 5) Performance optimization and best practices include mirror optimization, resource management and security improvement.

The steps to deploy containerized applications using Kubernetes and Docker include: 1. Build a Docker image, define the application image using Dockerfile and push it to DockerHub. 2. Create Deployment and Service in Kubernetes to manage and expose applications. 3. Use HorizontalPodAutoscaler to achieve dynamic scaling. 4. Debug common problems through kubectl command. 5. Optimize performance, define resource limitations and requests, and manage configurations using Helm.

Docker is an open source platform for developing, packaging and running applications, and through containerization technology, solving the consistency of applications in different environments. 1. Build the image: Define the application environment and dependencies through the Dockerfile and build it using the dockerbuild command. 2. Run the container: Use the dockerrun command to start the container from the mirror. 3. Manage containers: manage container life cycle through dockerps, dockerstop, dockerrm and other commands.
