My Node.js droplet can't connect to DigitalOcean Managed redis

Hello,

When connecting to DigitalOcean Managed Redis, you need to use the rediss protocol because it requires connections to be made over TLS.

To connect using the redis package with TLS, follow the example below:

const Redis = require('redis');

const host = 'db-redis.db.ondigitalocean.com';
const port = '25061';
const username = 'user';
const password = 'secret';
const url = `rediss://${username}:${password}@${host}:${port}`;

const client = Redis.createClient({
    url: url,
    tls: {}
});

client.on('error', (err) => {
    console.error('Redis Client Error', err);
});

(async () => {
    try {
        await client.connect();
        console.log('Connected to Redis');
    } catch (err) {
        console.error('Error connecting to Redis', err);
    }
})();

If you are using sockets and need to enable rediss, pass the necessary options through adapterOptions:

sockets: {
    onlyAllowOrigins: ['https://my-website.com'],

    adapterOptions: {
        user: 'username',
        pass: 'password',
        host: 'host',
        port: 9999,
        db: 2, // pick a number
        tls: {},
    },

    adapter: '@sailshq/socket.io-redis',
},

For session management, pass the tls: {} empty object in the configuration:

session: {
    pass: 'password',
    host: 'host',
    port: 9999,
    db: 1, // pick a number not used by sockets
    tls: {},
    cookie: {
        secure: true,
        maxAge: 24 * 60 * 60 * 1000, // 24 hours
    },
},

Basically, by including the tls: {} option, you make sure that your connection to the Redis instance uses TLS, providing the necessary security for your application.
