ToolDev with Concourse and go

[dio-trinny]

Hello all!

I am trying to write a new cli tool to interact with concourse without having to tell my users to install fly, just this cli tool. I've run into a bit of an issue with go mod however, and I am trying to work out what it is that I am doing wrong. In particular, building this go file:

package main

import (
	"github.com/concourse/fly/commands"
)

func main() {
	fl := commands.Fly
	fl.Target = "whatever"

	lgCmd := commands.LoginCommand{
		ATCURL: "whatever",
	}
	err := lgCmd.Execute([]string{})
	if err != nil {
		panic(err)
	}
}

Results in these errors:

$ go mod tidy

I have checked that this package is actually shipped with concourse releases, so I am kind of lost.. Any help would be greatly appreciated!

The concourse/fly repo is archived and has no code in it, you should be using the concourse/concourse mono-repo instead. You might also want to take a look at using the go-concourse client library instead of fly.

Note: due to how go mod versioning works, you'll have to get the repo by sha: go get github.com/concourse/concourse@248606d for v6.7.1. Eventually we'll separate out go-concourse into a proper go mod versioned repo, but for now you'll have to go get it by sha.

thank you for your reply @chenbh ! I am trying to perform the Login and SetPipeline operations that fly allows you to, but go-concourse doesn't seem to export it.

What would be the best way of going about it in your opinion?!

Logging in is done at the http.Client level, you can find examples of it at https://github.com/concourse/concourse/blob/master/fly/rc/target.go#L155 or https://github.com/alphagov/terraform-provider-concourse/blob/master/pkg/client/client.go#L35

Pipeline operations are at the team level
