Changing hostname and port with Vapor 3

The Config/server.json file doesn't seem to be read by Vapor 3, and as such I can't configure the hostname and port that a Vapor 3 app binds to.

Does Vapor 3 have a different method for this?

If you need to configure different hosts for production and development you can switch the app environment:

Vapor 4 • Swift 5.10

public func configure(_ app: Application) throws {
    switch app.environment {
    case .production:
        app.http.server.configuration = .init(address: .hostname("222.111.111.222", port: nil))
    case .development, .testing:
        app.http.server.configuration = .init(address: .hostname("0.0.0.0", port: 8080))
    default: break
    }
    // code ...
}

in Vapor 4

app.http.server.configuration.hostname = "127.0.0.1"
app.http.server.configuration.port = 8000

in Vapor 3 

services.register(NIOServerConfig.default(hostname: "127.0.0.1", port: 8000))

Official Solution (as sanctioned by the maintainers)

You can use NIOServerConfig.

let serverConfiure = NIOServerConfig.default(hostname: "0.0.0.0", port: 9090)
services.register(serverConfiure)

Vapor version is 3.0.3

What iOS Guy had written needs a bit of modification for Vapor 3.3.1 // Define Hostname & Port to listen to ... let myServerConfig = NIOServerConfig.default(hostname: "localhost", port: 8081) services.register(myServerConfig)

So NIOServerConfig.default can be used only with two parameters hostname & port and it can be used if one just wants to change the port number.

In vapor: stable 3.1.10

open: configure.swift

In: public func configure()

Add the following:

// Define Hostname & Port to listen to ...
let myServerConfig = NIOServerConfig.default(hostname: "servers-hostname.local", port: 8080)
services.register(myServerConfig)

Editing the Run scheme's "Arguments Passed on Launch" also worked for me

Be sure you are using the Vapor 3 version then use this:

vapor run --hostname=0.0.0.0 --port=8080

If you don't add = after the parameter, you are going to receive the follow complaint:

CommandError: Unknown command 8080

If you do as I recommended above, you are going to receive:

[Deprecated] --option=value syntax is deprecated.

Please use --option value (with no =) instead but the command will run and works fine.

I was unable to find a way to run this command without = after the parameter.

My $0.02

import Vapor

/// Called before your application initializes.
///
/// [Learn More →](https://docs.vapor.codes/3.0/getting-started/structure/#configureswift)
public func configure(
    _ config: inout Config,
    _ env: inout Environment,
    _ services: inout Services
    ) throws {
    if env == .development {
        services.register(Server.self) { container -> EngineServer in
            var serverConfig = try container.make() as EngineServerConfig
            serverConfig.port = 8989
            serverConfig.hostname = "192.168.31.215"
            let server = EngineServer(
                config: serverConfig,
                container: container
            )
            return server
        }
    }

    //Other configure code
}

It works perfectly on Vapor 3.0.0 RC 2.4.1

You could also register your EngineServerConfig in services.

In configure.swift, insert the code below:

let myServerConfig = try EngineServerConfig.detect(from: &env, port: 8081)
services.register(myServerConfig)

This should work for 3.0.0-rc.2.2

Currently, you can set the port and hostname when running your server:

swift run Run --hostname 0.0.0.0 --port 9000

There appears to be struct-based configuration for EngineServer but I don’t think it is configurable at run time just yet. The last time the Vapor developer answered this question (on their Slack) the command-line argument method was the suggested one.

You can set the hostname and port with command line flags:

--hostname localhost --port 8080
