Fastify does not work on custom apps.

[pedrocm]

I tried to deploy a custom app that a made in fastify (nodejs) build with ESBuild to keep everything in a single file. But an application build with fastify does not complete the health check.

const fastify = require('fastify')();

fastify.get('/', async (request, reply) => {
  return 'Hello, World!';
});

const start = async () => {
  try {
    await fastify.listen(3000);
    console.log('Server is running on port 3000');
  } catch (err) {
    console.error(err);
    process.exit(1);
  }
};

start();

Does any one already deploy a backend api app made with Fastify to cloudron?

I am no fastify expert, but the Cloudron healthcheck (defaulting to /) expects a 2hundred something (so like 200, 201, ...) http status code to let is succeed.

Do you see your route handler being hit every 10seconds for a start and does that route handler reply with a 200 if you just return a string from the function?

In the CloudronManifest.json be sure to have httpPort to 3000.

Also, does await fastify.listen(3000); listen on 0.0.0.0 or just localhost ? It should listen on 0.0.0.0 / :: to be able to reachable from outside the container.

You can check if listen({ host: '0.0.0.0', port: 3000 }) makes it better.
