HTTP Response Application

Overview

This application is a simple HTTP server written in Go. It responds to all incoming HTTP requests with a static response code and body. These values are configurable via environment variables.

Configuration

Environment Variables

• HTTP_RESPONSE_BODY: The body of the HTTP response. If not set, the default response body is "ok".
• HTTP_RESPONSE_CODE: The HTTP status code to be returned in responses. If this variable is not set or is set to a non-integer value, the default response code is 200 (OK).

Default Values

• Default Response Body: "ok"
• Default Response Code: 200

Running the Application

With Go

Set the environment variables HTTP_RESPONSE_BODY and HTTP_RESPONSE_CODE as needed. For example, in a Unix-like shell, you can set them as follows:

export HTTP_RESPONSE_BODY="Your Response Here"
export HTTP_RESPONSE_CODE=404
go run main.go

The server will start and listen on port 8080.

With Docker

Set the environment variables HTTP_RESPONSE_BODY and HTTP_RESPONSE_CODE as needed. For example, in a Unix-like shell, you can set them as follows:

docker run -it --rm \
   -p 8080:8080 \
   -e HTTP_RESPONSE_BODY="Maintenance here" \
   -e HTTP_RESPONSE_CODE=503 \
   infrabuilder/http-dummy-server

The server will start and listen on port 8080.

Accessing the Server

Once the server is running, it can be accessed using any HTTP client (like a web browser or curl) by navigating to http://localhost:8080. The server will respond with the configured response body and status code.
