  }); // Deploys application to Cloudron platform
}

deployToCloudron().then(() => console.log('Deployment to Cloudron completed.'));

Preparing Cloudron Manifest: Before deployment, replace version placeholders in the Cloudron Manifest:

import { Npmci } from '@ship.zone/npmci';
import * as fs from 'fs';
import * as path from 'path';

async function prepareCloudronManifest(version: string) {
  const manifestPath = path.join(process.cwd(), "CloudronManifest.json");
  let manifestFile = fs.readFileSync(manifestPath, { encoding: 'utf-8' });
  manifestFile = manifestFile.replace(/##version##/g, version);
  fs.writeFileSync(manifestPath, manifestFile);
  console.log('CloudronManifest prepared');
}

async function deployWithPreparedManifest() {
  const npmciInstance = new Npmci();
  await npmciInstance.start();
  
  await prepareCloudronManifest('1.0.0');
  await npmciInstance.cloudronManager.handleCli({
    _: ['cloudron', 'deploy']
  }); // Deploys application to Cloudron platform
}

deployWithPreparedManifest().then(() => console.log('Deployment to Cloudron with manifest preparation completed.'));

    }
    
    pushDockerfilesToRegistry().then(() => console.log('Docker push process completed.'));
    

Dockerfile Class Example:

Here's a snippet showcasing how the Dockerfile class can be used to handle Dockerfile-specific operations:

import { Dockerfile } from '@ship.zone/npmci';

async function handleDockerfileOperations() {
  // Initialize Dockerfile instances
  const dockerfile1 = new Dockerfile(/* required parameters */);
  const dockerfile2 = new Dockerfile(/* required parameters */);

  // Read and sort Dockerfiles
  const dockerfiles = await Dockerfile.readDockerfiles(/* required parameters */);
  const sortedDockerfiles = await Dockerfile.sortDockerfiles(dockerfiles);

  // Build and Test Dockerfiles
  await Dockerfile.buildDockerfiles(sortedDockerfiles);
  await Dockerfile.testDockerfiles(sortedDockerfiles);

  // Push Dockerfile images to a registry
  for (const dockerfile of sortedDockerfiles) {
    await dockerfile.push(/* registry and tag parameters */);
  }

  console.log('Dockerfile operations completed successfully.');
}

handleDockerfileOperations().then(() => console.log('Dockerfile processing flow completed.'));

This completes the comprehensive guide to @ship.zone/npmci. With the examples and explanations provided, you should be able to harness the full power and flexibility of the library to streamline your CI/CD processes effectively. undefined
