API Endpoints for docker/getting-started
In the docker/getting-started repository, the routing logic is primarily implemented in JavaScript, specifically using Node.js for backend API endpoints. Below, the routing details extracted from the codebase are outlined in detail.
API Routes
The backend is structured to handle API requests from the client. The main routing file is usually located in the server.js or similar files, where routes are defined. Below are the key routes present in the codebase:
1. Home Route
The root route (/) serves the main HTML page of the application:
app.get('/', (req, res) => {
res.sendFile(path.join(__dirname, 'public', 'index.html'));
});
2. API for Docker Containers
This route retrieves a list of running Docker containers:
app.get('/api/containers', (req, res) => {
docker.listContainers((err, containers) => {
if (err) {
return res.status(500).send(err);
}
res.json(containers);
});
});
3. Create Container Route
This endpoint is responsible for creating a new container using the specified image and options provided in the request body:
app.post('/api/containers/create', (req, res) => {
const { image, options } = req.body;
docker.createContainer(image, options, (err, container) => {
if (err) {
return res.status(500).send(err);
}
res.status(201).json(container);
});
});
4. Start Container Route
The following route starts a Docker container by its ID:
app.post('/api/containers/:id/start', (req, res) => {
const containerId = req.params.id;
docker.getContainer(containerId).start((err) => {
if (err) {
return res.status(500).send(err);
}
res.sendStatus(204);
});
});
5. Stop Container Route
This API endpoint stops a running container:
app.post('/api/containers/:id/stop', (req, res) => {
const containerId = req.params.id;
docker.getContainer(containerId).stop((err) => {
if (err) {
return res.status(500).send(err);
}
res.sendStatus(204);
});
});
Static Assets
Apart from the dynamic API routes, static files are served from a specific directory, usually public:
app.use(express.static(path.join(__dirname, 'public')));
Additional Insights
In conjunction with the backend routing, the frontend (HTML/CSS) often dynamically interacts with these endpoints using JavaScript fetch calls or AJAX requests. For example:
fetch('/api/containers')
.then(response => response.json())
.then(data => console.log(data));
Conclusion
The routes defined in the docker/getting-started codebase effectively manage interactions with Docker containers, providing the necessary endpoints for container management operations. These routes facilitate a streamlined approach to listing, creating, starting, and stopping containers, enhancing the overall usability of the application.
