How to connect Redis by railway connect, does a template exist to connect Redis with railway connect? Now I connect with username/password, but I'm finding a way to connect without a username. ProjectId: 38fe79a8-c127-4e50-ba67-eab1ce076502 ServiceId: e95b93c0-d4a0-4be2-8a1b-2addbf59d616

there would need to be a redis plugin in the project you've linked with the cli railway connect should not ask you for a username or password to connect to redis, since that would defeat the purpose of the command

guoyuyan•16mo ago

You mean railway connect is an interactive input to connect Redis? It also needs username and password?

Brody•16mo ago

it does not need a username or password

guoyuyan•16mo ago

sorry, I miss not, where is the plugin?

Brody•16mo ago

have you created a project in railway?

guoyuyan•16mo ago

yes, 38fe79a8-c127-4e50-ba67-eab1ce076502 is the project id

Brody•16mo ago

does that project have a redis plugin in it? (I'm just a community member I can't see anything about your project with your id)

guoyuyan•16mo ago

I add a redis server, but I don't know what is redis plugin.

guoyuyan•16mo ago

Brody•16mo ago

a plugin is just the name we give to the provided databases, mysql plugin, mongodb plugin, etc but yeah that looks good to me do you have the railway cli installed on your computer?

guoyuyan•16mo ago

I want to use railway connect in the kuai server but not on my computer. Currently, I use the variable to connect it.

Brody•16mo ago

railway connect is for your computer, I think you're mistaken if you want to connect to the redis database from your kuai service you are going to first need to setup all the needed variable references for redis https://docs.railway.app/develop/variables#reference-variables

guoyuyan•16mo ago

got that, I mistake thought there is exist one way to connect it to other services without username/password

Brody•16mo ago

please do that and then show me another screenshot of your service variables

guoyuyan•16mo ago

I have connected Redis success with variables. Thank you for your help. I mistake thought that railway connect is used for other services.

Brody•16mo ago

so all good, problem solved?

guoyuyan•16mo ago

yes, I have another problem with the private network between the two services. Do you have a template that how to use a private network?

Brody•16mo ago

I do, but I'm gonna need more information on your desired usecase

guoyuyan•16mo ago

The kuai-mvp-dapp-ui is created by next, the kuai service is created by Koa, and I want to call kuai api by private network from kuai-mvp-dapp-ui

Brody•16mo ago

okay one sec while I Google what Koa is okay Koa is express but better

guoyuyan•16mo ago

I have set all of the service hosts to ipv6(::1), but it seems not to call kuai success by a private network. And after I set host to ::1, the public service is also failed.

Brody•16mo ago

so this request would need to be done by the next backend, the client browser of the site will not be able to call the private network, wouldnt be very private if that was possible can you show me the line of code that contains your app.listen call?

guoyuyan•16mo ago

  const server = app.listen(port, host, function () {
    const address = (() => {
      const _address = server.address()
      if (!_address) {
        return ''
      }

      if (typeof _address === 'string') {
        return _address
      }

      return `http://${_address.address}:${_address.port}`
    })()

    console.info(`kuai app listening to ${address}`)
  })

  const server = app.listen(port, host, function () {
    const address = (() => {
      const _address = server.address()
      if (!_address) {
        return ''
      }

      if (typeof _address === 'string') {
        return _address
      }

      return `http://${_address.address}:${_address.port}`
    })()

    console.info(`kuai app listening to ${address}`)
  })

the port and host is from variable

Brody•16mo ago

and what is host and port set to?

guoyuyan•16mo ago

Brody•16mo ago

delete both those variables and use this code instead

const port = process.env.PORT || 3000;

const server = app.listen(port, '::', function () {
    const address = (() => {
        const _address = server.address();
        if (!_address) {
            return '';
        }

        if (typeof _address === 'string') {
            return _address;
        }

        return `http://${_address.address}:${_address.port}`;
    })()

    console.info(`kuai app listening to ${address}`);
});

const port = process.env.PORT || 3000;

const server = app.listen(port, '::', function () {
    const address = (() => {
        const _address = server.address();
        if (!_address) {
            return '';
        }

        if (typeof _address === 'string') {
            return _address;
        }

        return `http://${_address.address}:${_address.port}`;
    })()

    console.info(`kuai app listening to ${address}`);
});

guoyuyan•16mo ago

thanks, I will try

Brody•16mo ago

and you are calling the koa service from the next backend right?

guoyuyan•16mo ago

actually, in the next front end.

Brody•16mo ago

thats not possible

guoyuyan•16mo ago

Should I use nginx to proxy these two service?

Brody•16mo ago

wait let me rephrase that question are you going to be calling the koa service's private domain from the next backend?

guoyuyan•16mo ago

I guess I need proxy the request from next, otherwise, the request will send from the browser to koa service, and the browser cannot visit the private network. Am I right?

Brody•16mo ago

you are correct, but you dont need a proxy, just call the koa public domain

guoyuyan•16mo ago

That's right, if I don't want to expose the koa, I need a proxy.

Brody•16mo ago

you do need to expose the koa service though a proxy is just exposing the service with extra steps, it doesnt add any of the security benifts you think it would

guoyuyan•16mo ago

You are correct. Thank you very much. Have a good day.

Brody•16mo ago

well that was easy, i thought id need to do some more convincing glad i could help!
