To set debug environment variables in VSCode, you need to use the "environment" array configuration in the launch.json file. The specific steps are as follows: 1. Add "environment" array to the debugging configuration of launch.json, and define variables in key-value pairs, such as API_ENDPOINT and DEBUG_MODE; 2. You can load variables through .env files to improve management efficiency, and use envFile to specify file paths in launch.json; 3. If you need to overwrite the system or terminal variables, you can directly redefine them in launch.json; 4. Note that

To expose Docker container ports, the host needs to access the container service through port mapping. 1. Use the dockerrun-p[host_port]:[container_port] command to run the container, such as dockerrun-p8080:3000my-web-app; 2. Use the EXPOSE instruction to mark the purpose in the Dockerfile, such as EXPOSE3000, but the port will not be automatically published; 3. Configure the ports segment of the yml file in DockerCompose, such as ports:-"8080:3000"; 4. Use dockerps to check whether the port map is generated after running.

There are three main ways to set environment variables in PHP: 1. Global configuration through php.ini; 2. Passed through a web server (such as SetEnv of Apache or fastcgi_param of Nginx); 3. Use putenv() function in PHP scripts. Among them, php.ini is suitable for global and infrequently changing configurations, web server configuration is suitable for scenarios that need to be isolated, and putenv() is suitable for temporary variables. Persistence policies include configuration files (such as php.ini or web server configuration), .env files are loaded with dotenv library, and dynamic injection of variables in CI/CD processes. Security management sensitive information should be avoided hard-coded, and it is recommended to use.en

To enable PHP containers to support automatic construction, the core lies in configuring the continuous integration (CI) process. 1. Use Dockerfile to define the PHP environment, including basic image, extension installation, dependency management and permission settings; 2. Configure CI/CD tools such as GitLabCI, and define the build, test and deployment stages through the .gitlab-ci.yml file to achieve automatic construction, testing and deployment; 3. Integrate test frameworks such as PHPUnit to ensure that tests are automatically run after code changes; 4. Use automated deployment strategies such as Kubernetes to define deployment configuration through the deployment.yaml file; 5. Optimize Dockerfile and adopt multi-stage construction

To access services in Docker container from the host, use port mapping. The specific steps are: 1. Use -p to specify host_port:container_port when starting the container, such as dockerrun-d-p8080:80nginx; 2. Multiple ports can be configured through multiple -p parameters or DockerCompose files; 3. IP address binding can be limited, such as -p192.168.1.100:8080:80; 4. Use dockerps or dockerinspect to view port mapping details.

The key to debugging code with VSCode in Docker containers is to configure the development environment and connection methods. 1. Prepare a mirror with development tools, install necessary dependencies such as debugpy or node, and use the official devcontainers image to simplify configuration; 2. Mount the source code and enable the Remote-Containers plug-in, create .devcontainer folders and configuration files, and realize in-container development; 3. Configure the debugger, add debug settings for the corresponding language in launch.json, and enable the listening port in the code; 4. Solve common problems, such as exposing the debug port, ensuring the host is 0.0.0.0, and use postCreateC

Using the correct PHP basic image and configuring a secure, performance-optimized Docker environment is the key to achieving production ready. 1. Select php:8.3-fpm-alpine as the basic image to reduce the attack surface and improve performance; 2. Disable dangerous functions through custom php.ini, turn off error display, and enable Opcache and JIT to enhance security and performance; 3. Use Nginx as the reverse proxy to restrict access to sensitive files and correctly forward PHP requests to PHP-FPM; 4. Use multi-stage optimization images to remove development dependencies, and set up non-root users to run containers; 5. Optional Supervisord to manage multiple processes such as cron; 6. Verify that no sensitive information leakage before deployment

Building an independent PHP task container environment can be implemented through Docker. The specific steps are as follows: 1. Install Docker and DockerCompose as the basis; 2. Create an independent directory to store Dockerfile and crontab files; 3. Write Dockerfile to define the PHPCLI environment and install cron and necessary extensions; 4. Write a crontab file to define timing tasks; 5. Write a docker-compose.yml mount script directory and configure environment variables; 6. Start the container and verify the log. Compared with performing timing tasks in web containers, independent containers have the advantages of resource isolation, pure environment, strong stability, and easy expansion.
