How to solve the problem when docker fails to run nginx binding configuration file
Direct execution of the startup command will fail
pull image:
docker pull nginx
Then execute the startup command:
docker run -d -p 80:80 -p 443:443 --name nginx \ -v /mydata/nginx/html:/usr/share/nginx/html \ -v /mydata/nginx/conf/nginx.conf:/etc/nginx/nginx.conf \ -v /mydata/nginx/conf/conf.d:/etc/nginx/conf.d \ -v /mydata/nginx/logs:/var/log/nginx \ -v /mydata/nginx/cache:/var/cache/nginx \ --restart=always nginx
If /mydata/nginx/conf/nginx. The conf file does not exist, and a docker error will appear here because docker does not allow binding files that do not exist.
And directly create an empty /mydata/nginx/conf/nginx.confAlthough docker will not report an error, nginx cannot start normally in the container, through docker ps -aCommand view, nginx will be in exit or always restart state, because the operation of nginx depends on the relevant configuration in the nginx.conf configuration file .
Solution ideas and methods
First run a container without using -v binding, and then copy the relevant files in the container directly to the specified location. After that, you can delete the container and run it directly. the startup command.
The specific operations are as follows:
First create the relevant folders:
mkdir -p \ /mydata/nginx/html \ /mydata/nginx/conf \ /mydata/nginx/logs \ /mydata/nginx/cache
Run an nginx container:
docker run -d --name nginx nginx
Copy the configuration file and folder to Host specified directory:
docker cp nginx:/etc/nginx/nginx.conf /mydata/nginx/conf/ docker cp nginx:/etc/nginx/conf.d /mydata/nginx/conf.d
Delete the original container:
docker rm -f nginx
Run the startup command, -v binds the relevant volume:
docker run -d -p 80:80 -p 443:443 --name nginx \ -v /mydata/nginx/html:/usr/share/nginx/html \ -v /mydata/nginx/conf/nginx.conf:/etc/nginx/nginx.conf \ -v /mydata/nginx/conf/conf.d:/etc/nginx/conf.d \ -v /mydata/nginx/logs:/var/log/nginx \ -v /mydata/nginx/cache:/var/cache/nginx \ --restart=always nginx
Move the copyconf.dThe files in the directory to the correct location:
mv /mydata/nginx/conf.d/* /mydata/nginx/conf/conf.d/ rm -rf /mydata/nginx/conf.d
So that the nginx container can run normally, and we will use the above operation to move the nginx.conf file and conf.d The directories are all mapped to the host machine. If you need to modify the nginx.conf file or add the .conf file to conf.d in the future, you only need to modify it on the host machine. Just operate the corresponding position.

How to set environment variables in PHP environment Description of adding PHP running environment variables
Jul 25, 2025 pm 08:33 PM
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

Jul 25, 2025 pm 08:54 PM
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
