How to solve the problem of failed installation of docker in centos?
CentOS installation Docker error message:
##Problem: package docker-ce-3:19.03.2-3.el7. x86_64 requires containerd.io >= 1.2.2-3, but none of the providers can be installedChecked and found that the containerd.io package has been installed, but the version is 1.2.0; so this installation failed The reason is that the containerd.io software package version is too lowSolution:- cannot install the best candidate for the job
- package containerd.io-1.2.2-3.3.el7 .x86_64 is excluded
- package containerd.io-1.2.2-3.el7.x86_64 is excluded
- package containerd.io-1.2.4-3.1.el7.x86_64 is excluded
- package containerd .io-1.2.5-3.1.el7.x86_64 is excluded
- package containerd.io-1.2.6-3.3.el7.x86_64 is excluded
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)
1. Check the Docker version, install the lower version, do not install the new version of Docker (it is not complicated here) Introducing the installation process of lower versions)
[root@localhost ~]# yum list docker-ce --showduplicates | sort -r //检查相应的软件包版本
[root@localhost ~]# yum -y install docker-ce-18.06.0.ce-3.el7 //安装低版本的软件包 [object Object]
2. Install the new version of containerd.io software package

Docker vs. Virtual Machines: A ComparisonMay 09, 2025 am 12:19 AMDocker 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.
Docker's Architecture: Understanding Containers and ImagesMay 08, 2025 am 12:17 AMThe 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.
The Power of Docker: Containerization ExplainedMay 07, 2025 am 12:07 AMDocker 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.
Kubernetes and Docker: Deploying and Managing Containerized AppsMay 06, 2025 am 12:13 AMThe 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: An Introduction to Containerization TechnologyMay 05, 2025 am 12:11 AMDocker 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.
Docker and Linux: Building Portable ApplicationsMay 03, 2025 am 12:17 AMHow to build portable applications with Docker and Linux? First, use Dockerfile to containerize the application, and then manage and deploy the container in a Linux environment. 1) Write a Dockerfile and package the application and its dependencies into a mirror. 2) Build and run containers on Linux using dockerbuild and dockerrun commands. 3) Manage multi-container applications through DockerCompose and define service dependencies. 4) Optimize the image size and resource configuration, enhance security, and improve application performance and portability.
Docker and Kubernetes: The Power of Container OrchestrationMay 02, 2025 am 12:06 AMDocker and Kubernetes improve application deployment and management efficiency through container orchestration. 1.Docker builds images through Dockerfile and runs containers to ensure application consistency. 2. Kubernetes manages containers through Pod, Deployment and Service to achieve automated deployment and expansion.
Docker vs. Kubernetes: Key Differences and SynergiesMay 01, 2025 am 12:09 AMDocker and Kubernetes are leaders in containerization and orchestration. Docker focuses on container lifecycle management and is suitable for small projects; Kubernetes is good at container orchestration and is suitable for large-scale production environments. The combination of the two can improve development and deployment efficiency.
