A simple HTTP server implemented in C++ using the C++ REST SDK. It listens for incoming HTTP GET requests and responds with a JSON message. This is for Docker's C++ Language Guide.

API

The server only supports the HTTP GET method at the moment. When a GET request is received, the server responds with a JSON object:

{
    "message": "OK"
}

Running with Docker Compose

Below is the Dockerfile for the C++ application:

# Use the official Ubuntu image as the base image
FROM ubuntu:latest

# Set the working directory in the container
WORKDIR /app

# Install necessary dependencies
RUN apt-get update && apt-get install -y \
    g++ \
    libcpprest-dev \
    libboost-all-dev \
    libssl-dev \
    cmake

# Copy the source code into the container
COPY ok_api.cpp .

# Compile the C++ code
RUN g++ -o ok_api ok_api.cpp -lcpprest -lboost_system -lboost_thread -lboost_chrono -lboost_random -lssl -lcrypto

# Expose the port on which the API will listen
EXPOSE 8080

# Command to run the API when the container starts
CMD ["./ok_api"]

To run this application using Docker Compose, you'll need to create a compose.yml file.

Here's the compose.yml file:

services:
  ok-api:
    image: ok-api
    build:
      context: .
      dockerfile: Dockerfile
    ports:
      - "8080:8080"

To build and run the Docker image using Docker Compose, use the following command:

docker-compose up

This will build the Docker image and then run it, mapping the container's port 8080 to port 8080 on the host machine. You can then access the API by visiting http://localhost:8080 in your web browser.
