HomeOperation and MaintenanceDockerWhat should I do if docker cannot access the container?

方法:1、用“vi/etc/sysctl.conf”命令修改“sysctl.conf”文件;2、在文件中添加“net.ipv4.ip_forward=1”;3、用“systemctl restart network”命令重启服务器网络即可。

What should I do if docker cannot access the container?

本教程操作环境:linux7.3系统、docker-1.13.1版、Dell G3电脑。

docker无法访问容器怎么办

首先根据以上提示信息大概搜索一下,基本都指向修改/etc/sysctl.conf文件

没有开启转发,网桥配置完后,需要开启转发,不然容器启动后,就会没有网络

 vi /etc/sysctl.conf   或  vi /usr/lib/sysctl.d/00-system.conf

尝试修改,在sysctl.conf文件中追加以下

# 1代表启用
net.ipv4.ip_forward=1

然后使用以下命令重启服务器网络

systemctl restart network

再次通过浏览器访问docker容器相关服务,一切正常

查看是否修改成功

sysctl net.ipv4.ip_forward

如果返回为“net.ipv4.ip_forward = 1”则表示成功了。

Docker vs. Virtual Machines: A ComparisonDocker vs. Virtual Machines: A ComparisonMay 09, 2025 am 12:19 AM

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.

Docker's Architecture: Understanding Containers and ImagesDocker's Architecture: Understanding Containers and ImagesMay 08, 2025 am 12:17 AM

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.

The Power of Docker: Containerization ExplainedThe Power of Docker: Containerization ExplainedMay 07, 2025 am 12:07 AM

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.

Kubernetes and Docker: Deploying and Managing Containerized AppsKubernetes and Docker: Deploying and Managing Containerized AppsMay 06, 2025 am 12:13 AM

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: An Introduction to Containerization TechnologyDocker: An Introduction to Containerization TechnologyMay 05, 2025 am 12:11 AM

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.

Docker and Linux: Building Portable ApplicationsDocker and Linux: Building Portable ApplicationsMay 03, 2025 am 12:17 AM

How 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 OrchestrationDocker and Kubernetes: The Power of Container OrchestrationMay 02, 2025 am 12:06 AM

Docker 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 SynergiesDocker vs. Kubernetes: Key Differences and SynergiesMay 01, 2025 am 12:09 AM

Docker 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.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
