  "explanation": "There, just right of center, what is that? The surface of Mars keeps revealing new surprises with the recent discovery of finger-like rock spires. The small nearly-vertical rock outcrops were imaged last month by the robotic Curiosity rover on Mars. Although similar in size and shape to small snakes, the leading explanation for their origin is as conglomerations of small minerals left by water flowing through rock crevices. After these relatively dense minerals filled the crevices, they were left behind when the surrounding rock eroded away.  Famous rock outcrops on Earth with a similar origin are called hoodoos. NASA's Curiosity Rover continues to search for new signs of ancient water in Gale Crater on Mars, while also providing a geologic background important for future human exploration.

Deployment

Go-APOD can be self-hosted, either with Docker, via the 1-click Vercel or Heroku deployment, or by running the executable directly.
A NASA API Key is required, which you can sign up for at api.nasa.gov.

Vercel

Heroku

Docker

A multi-arch container is available on DockerHub, under lissy93/apod, or GHCR as ghcr.io/lissy93/go-apod.
Or, use this docker-compose.yml template, and just populate with your API key and run docker compose up.

docker run -p 8080:8080 -e NASA_API_KEY='XXX' -d lissy93/apod

From Executable

Each release has pre-compiled binaries attached for Windows, Mac and Linux, which can be run directly. From the Releases Page, download and extract the version for your system, then execute it with: NASA_API_KEY='XXX' ./go-apod

From Source

See the Building Locally section below

Building Locally

If you haven't already done so, you'll need to install Go Lang.
Then clone the repo git clone https://github.com/Lissy93/go-apod.git && cd go-apod

• Run Tests > go test

Environmental Variables

• NASA_API_KEY (Required) - Your API Key, you can sign up for one at api.nasa.gov
• PORT (Optional) - The port to start the web server on, defaults to 8080
• CORS_ALLOWED_ORIGINS (Optional) - List of origins which can use the API, defaults to * / all
• NASA_BASE_URL (Optional) - The base URL upstream GET requests, defaults to NASA's APOD API

App

The service also includes an optional simple web app, which can be used to show todays image and associated information from the API.
