+# This RUN command performs multiple setup tasks for the development environment:
+# 1. Updates the package lists for upgrades and new package installations.
+# 2. Installs Java Development Kit (JDK), Java Runtime Environment (JRE), and databases (PostgreSQL, MariaDB, SQLite3) for various development needs.
+# 3. Downloads and installs Apache Maven for Java project management and build.
+# 4. Adds Maven to the PATH environment variable for easy command-line access.
+# 5. Sets up Node.js from the Nodesource repository, enabling the use of modern JavaScript tooling.
+# 6. Enables Yarn package manager via Corepack for managing JavaScript packages.
+# 7. Configures the `vscode` user to execute sudo commands without a password for easier container management.
+# 8. Modifies PostgreSQL's authentication method to md5 for increased security.
+# 9. Cleans up the apt cache and temporary files to reduce the image size.

+# This RUN command sets up essential Go packages and tools for API documentation, release management, and email testing, along with OpenAPI Generator and Yarn package manager:
+# 1. Installs Swag for automatically generating RESTful API documentation with Swagger 2.0.
+# 2. Installs GoReleaser, a tool to streamline the release process for Go applications, supporting various platforms and packaging methods.
+# 3. Installs MailHog, an email testing tool for developers, allowing the interception and viewing of emails sent from the development environment.
+# 4. Creates a directory for the OpenAPI Generator, which is used for generating API clients, server stubs, and API documentation from OpenAPI Specifications.
+# 5. Downloads the OpenAPI Generator CLI jar file, enabling the generation of API clients and documentation from a command line interface.
+# 6. Activates the Yarn package manager via Corepack, preparing the environment for JavaScript package management and development.
