I'm used to deploying HTTPS Node apps on DigitalOcean servers using Docker, the Express framework and the https package like this:
const https = require('https');
const app = express();
// ...
const ssl = {
key: fs.readFileSync(process.env.PRIVATE_KEY),
cert: fs.readFileSync(process.env.CERT),
ca: fs.readFileSync(process.env.CHAIN),
};
const server = https.createServer(ssl, app);
server.listen({ port }, () => {
// ...
});
My app is inside a Docker container, but I expose the certicates that are on the droplet with the "v" option when I do docker run, like this:
-v /etc/letsencrypt/:/etc/letsencrypt
Finally, my Docker container is passed environment variables so that my Node app can know the paths to the various certificates files. For example,
CHAIN=/etc/letsencrypt/live/mydomain.com/chain.pem
And now, my Node app can read the certificates and create an HTTPS server with them.
I don't know if this setup is ideal, but it works well.
Now, I'm wondering how to do the same using the DigitalOcean App Platform.
So far, what I've done is this:
- Changed DNS for my domain to point to DigitalOcean's nameservers
- Created a DO-managed Let's Encrypt certificate for this domain, following this procedure: https://www.digitalocean.com/docs/accounts/security/certificates/
- Created a DO App, defining my app as a service
But I can't get it to work with the certificates and therefore, have my HTTPS app work.
Does anyone here have an idea?
