1. Basic environment
1. Operating system: CentOS 7.3
2. Docker version: 18.06.1
2 , Docker installation
1. Unzip
tar -xvf docker-18.06.1-ce.tgz
2. Move the contents of the unzipped docker file to the /usr/bin/ directory
cp docker/* /usr/bin/
3. Register docker as service
vim /etc/systemd/system/docker.service
Add the following configuration to docker.service and save it.
[Unit] Description=Docker Application Container Engine Documentation=https://docs.docker.com After=network-online.target firewalld.service Wants=network-online.target [Service] Type=notify # the default is not to use systemd for cgroups because the delegate issues still # exists and systemd currently does not support the cgroup feature set required # for containers run by docker ExecStart=/usr/bin/dockerd ExecReload=/bin/kill -s HUP $MAINPID # Having non-zero Limit*s causes performance problems due to accounting overhead # in the kernel.

4. Start
chmod +x /etc/systemd/system/docker.service #添加文件权限并启动docker systemctl daemon-reload #重载unit配置文件 systemctl start docker #启动Docker systemctl enable docker.service #设置开机自启
5. Verification
systemctl status docker #查看Docker状态 docker -v #查看Docker版本

Docker and Linux are perfect matches because they can simplify the development and deployment of applications. 1) Docker uses Linux's namespaces and cgroups to implement container isolation and resource management. 2) Docker containers are more efficient than virtual machines, have faster startup speeds, and the mirrored hierarchical structure is easy to build and distribute. 3) On Linux, the installation and use of Docker is very simple, with only a few commands. 4) Through DockerCompose, you can easily manage and deploy multi-container applications.

The difference between Docker and Kubernetes is that Docker is a containerized platform suitable for small projects and development environments; Kubernetes is a container orchestration system suitable for large projects and production environments. 1.Docker simplifies application deployment and is suitable for small projects with limited resources. 2. Kubernetes provides automation and scalability capabilities, suitable for large projects that require efficient management.

Use Docker and Kubernetes to build scalable applications. 1) Create container images using Dockerfile, 2) Deployment and Service of Kubernetes through kubectl command, 3) Use HorizontalPodAutoscaler to achieve automatic scaling, thereby building an efficient and scalable application architecture.

The main difference between Docker and Kubernetes is that Docker is used for containerization, while Kubernetes is used for container orchestration. 1.Docker provides a consistent environment to develop, test and deploy applications, and implement isolation and resource limitation through containers. 2. Kubernetes manages containerized applications, provides automated deployment, expansion and management functions, and supports load balancing and automatic scaling. The combination of the two can improve application deployment and management efficiency.

Installing and configuring Docker on Linux requires ensuring that the system is 64-bit and kernel version 3.10 and above, use the command "sudoapt-getupdate" and install it with the command "sudoapt-getupdate" and verify it with "sudoapt-getupdate" and. Docker uses the namespace and control groups of the Linux kernel to achieve container isolation and resource limitation. The image is a read-only template, and the container can be modified. Examples of usage include running an Nginx server and creating images with custom Dockerfiles. common

The reason for using Docker is that it provides an efficient, portable and consistent environment to package, distribute, and run applications. 1) Docker is a containerized platform that allows developers to package applications and their dependencies into lightweight, portable containers. 2) It is based on Linux container technology and joint file system to ensure fast startup and efficient operation. 3) Docker supports multi-stage construction, optimizes image size and deployment speed. 4) Using Docker can simplify development and deployment processes, improve efficiency and ensure consistency across environments.

Docker's application scenarios in actual projects include simplifying deployment, managing multi-container applications and performance optimization. 1.Docker simplifies application deployment, such as using Dockerfile to deploy Node.js applications. 2. DockerCompose manages multi-container applications, such as web and database services in microservice architecture. 3. Performance optimization uses multi-stage construction to reduce the image size and monitor the container status through health checks.

Select Docker in a small project or development environment, and Kubernetes in a large project or production environment. 1.Docker is suitable for rapid iteration and testing, 2. Kubernetes provides powerful container orchestration capabilities, suitable for managing and expanding large applications.
