• FROM ubuntu:22.04
  • The Docker image is based on Ubuntu version 22.04.
• ARG MYSQL_ROOT_PASSWORD=password
  • Pass argument of MySQL password of root account with “password” value
• ENV DEBIAN_FRONTEND=noninteractive
  • Disable interactive prompts during installation, because we can’t interact during image build process.
• RUN echo "mysql-server mysql-server/root-pass password '${MYSQL_ROOT_PASSWORD}'" | debconf-set-selections
  • Sets the root password for the MySQL server by piping a string with the password value from MYSQL_ROOT_PASSWORD into the debconf-set-selection ****command, which preconfigures the silent MySQL server installation script to use the specified password without prompting the user for input.
• RUN echo "mysql-server mysql-server/re-root-pass password '${MYSQL_ROOT_PASSWORD}'" | debconf-set-selections
  • Sets the root password confirmation for the MySQL server by piping a string with the password value from MYSQL_ROOT_PASSWORD into the debconf-set-selection ****command, which preconfigures the silent MySQL server installation script to use the specified password without prompting the user for input.
• RUN apt-get update
  • Update package lists for the Ubuntu package manager (APT) inside the Docker container, by fetching the latest versions of the packages from the configured repositories.
• apt-get install -y apache2 mysql-server netcat supervisor php8.1 php8.1-mysql
  • Install Apache2, MySQL server, PHP, netcat, supervisor, and MySQL extension for PHP
  • Apcache2 is a web server software that is used to serve web content over the internet or intranet.
  • MySQL is used to serve database system.
  • Netcat is used to ****network communication, allowing users to send and receive data across network connections. It can be used for port scanning, file transfers, and other network-related tasks.
  • Supervisor is used to manage multiple processes running inside the container. By running supervisor as the main process in the container, it can monitor and restart these processes if they fail or exit unexpectedly, providing a higher level of reliability and fault tolerance for the containerized application.
  • php8.1-mysql is a PHP extension package that provides support for connecting to MySQL databases from PHP scripts.
• apt-get -y autoremove
  • Remove any packages that were automatically installed as dependencies but are no longer required by any other packages in the system, to improve container performance.
