Configuration of Tyk when having many sites running in the server

I know that I have to install Tyk Gateway and Tyk Dashboard, do I need to assign a domain for each one of them? and register them in Caddy?

The dashboard works best with a hostname instead of an IP, the gateway doesn’t care, so no domain needed unless you want to expose the gateway publicly.

I saw in the installation instructions of Tyk Gateway that I have to provide --listenport=8080 in the documentation says that it is: “Tyk should listen on port 8080 for API traffic.” So, here should I put 8200 instead 8080 because my API is running in that port? if not, then how Tyk check for petitions of my API?

No, the gateway is a proxy, so the requests will be going from Caddy → Tyk → Application, i.e.:

MyRestAPI running on port 8200 -> Tyk (8080) -> MyRestAPI.com (80)

@Michell

Can be a problem to have applications that I will not monitorize running in the same server?

It should be ok so long as your traffic is low, it really depends on your traffic levels. Tyk needs redis and MongoDB, Redis can eat a lot of RAM because it stores all data in memory, and MongoDB (if your data set becomes very large), will want a lot of RAM to perform well (e.g. run aggregation pipelines across the raw log set instead of the aggregate log set).

@Michell

When I finish install and configure Tyk, I should use my API with MyRestAPI.com ?

Yes, but you’ll need to make sure that Caddy is sending on the host header when it proxies to Tyk, and In Tyk you want to set the REST API to be on a custom domain (MyRestAPI.com) with a listen path set to root (/), this way when the request comes from Caddy, Tyk will know what to listen for.
