Docker Configuration for stevedunn/vogen

This documentation provides an in-depth guide on how Docker is utilized within the development environment for the stevedunn/vogen project. The focus is on setting up and configuring Docker to work seamlessly with the development tools and workflow.

Dockerfile Overview

The primary component for Docker configuration in this project is the Dockerfile. Below is the complete Dockerfile used in the stevedunn/vogen repository:

FROM mcr.microsoft.com/dotnet/sdk:7.0

# SHELL ["powershell", "-Command", "$ErrorActionPreference = 'Stop'; $ProgressPreference = 'Continue'; $verbosePreference='Continue';"]

COPY . .

ENTRYPOINT [ "powershell.exe", "./Build.ps1" ]

Breakdown of the Dockerfile

Base Image:
```
FROM mcr.microsoft.com/dotnet/sdk:7.0
```
This line specifies the base image for the Docker container. The image is the .NET SDK version 7.0, which provides the necessary environment to build and run .NET applications.
Shell Configuration (commented out):
```
# SHELL ["powershell", "-Command", "$ErrorActionPreference = 'Stop'; $ProgressPreference = 'Continue'; $verbosePreference='Continue';"]
```
While this SHELL instruction is currently commented out, it is important to understand its purpose. When enabled, it configures the PowerShell shell to stop on errors, control progress output, and enable verbose output, providing better feedback during build execution.
Copying Source Code:
```
COPY . .
```
This command copies all files from the current directory (where the Docker build is executed) into the container. This is essential for making the source code and build scripts accessible inside the container.
Entry Point:
```
ENTRYPOINT [ "powershell.exe", "./Build.ps1" ]
```
The ENTRYPOINT specifies the command that will be run when the container starts. In this case, it runs Build.ps1 using PowerShell. This script contains the instructions for building the project, and it is critical for automating the build process within the Docker environment.

Building the Docker Image

To build the Docker image for the development environment, use the following command in the terminal:

docker build -t vogen-dev .

This command instructs Docker to build an image named vogen-dev using the Dockerfile in the current directory (denoted by .).

Running the Docker Container

After successfully building the image, you can run a container instance using the following command:

docker run --rm vogen-dev

The --rm flag ensures that the container is removed after it stops, helping to keep the development environment clean.

Additional Notes

It is important to ensure that Docker is installed and running on the development machine before executing these commands.
The Build.ps1 script is designed to handle the build process and may include additional steps such as restoring dependencies, compiling code, and running tests.

Conclusion

This configuration allows developers to leverage Docker for a consistent and isolated development environment when working with stevedunn/vogen. By using the provided Dockerfile, developers can streamline their workflow and focus on building without the hassle of local machine configuration issues.
