Update worker nodes configuration example

[floatdrop]

I got strange error, when used nodes notation with [ and ] - I don't remember exactly, but it was something like this:

Can't connect to [
"tcp:https://

Instead I wrote in drone.toml in same way as in environment variable and it worked.

I also ran into this under CentOS7. However, that won't solve the problem of needing to specify multiple workers in the future.

@solarfly73 doesn't placing them in one string (joined by ,) solves this for you?

This is actually a bug with the github.com/drone/config library which is not correctly parsing the string array from the toml file (the ENV parsing works fine).

I'm working on a quick patch that will resolve this issue at the library level, so that we can use the toml array syntax.

@solarfly73 we also have endpoints exposed that allow creating and removing workers on the fly, which I believe is what you are referring to. This hasn't been thoroughly tested, however, it is an important piece of functionality that will be available

work.Get("/api/workers", handler.GetWorkers)
work.Post("/api/workers", handler.PostWorker)
work.Delete("/api/workers", handler.DelWorker)

@bradrydzewski this would be very useful for admin ui!

I close this one in favor to https://github.com/drone/config/issues/1
