Go Hello World HTTP server

This is a simple HTTP server written in Go that responds with a message from a environment verriable.

Installation

To install the server, run the following command:

go get github.com/apxamccallum/go-hello-world-http/go-hello-world-http

Build with Docker

To build the server with Docker, run the following command:

docker build -t go-hello-world-http ./cmd/helloworld/

Run with Docker

To run the server with Docker, use the following command:

docker run --env-file ./cmd/helloworld/default.env -p 8282:80 --rm go-hello-world-http

This command starts a container with the go-hello-world-http image, maps the container's port 80 to the host's port 8282, and uses an environment file to set WEBBODY. Alternatively, you can run the server with a custom message by setting the WEBBODY environment variable:

docker run -e "WEBBODY=Hello World" -p 8282:80 --rm go-hello-world-http

Usage

To test the server, open a web browser and navigate to http://localhost:8282 or use the curl command:

curl http://localhost:8282

Launch with Docker Compose

Alternatively, you can launch the server with Docker Compose by running the following command:

docker-compose up

This command starts two instances of the server in containers and exposes them on port 8082 and 8083.
