It seems not to work on make run/site👀

How about using /docs-dev instead of /docs ?

[t-kikuc]

That might be because make run/site does not show docs (why??)

Please visit https://pipecd.dev/blog/2024/03/14/control-plane-on-local-by-docker-compose/ and modify the href. That worked.

@t-kikuc Got it. You're right. make run/site couldn't redirect the link.

It seems that the site is hosted by our file server, which works in a container. /docs is redirected to the latest version /docs-<latest-version>.

pipecd/docs/main.go

Lines 28 to 49 in b564c82

	const dir = "/public"
	// Don't update here manually. /hack/gen-release-docs.sh does.
	const latestPath = "/docs-v0.47.x/"
	func main() {
	var (
	doneCh = make(chan error)
	mux = http.NewServeMux()
	server = &http.Server{
	Addr: ":8080",
	Handler: mux,
	}
	fs = http.FileServer(http.Dir(dir))
	)
	mux.Handle("/", fs)
	// Redirect /docs/ to /docs-{latest-version}/
	mux.HandleFunc("/docs/", func(w http.ResponseWriter, r *http.Request) {
	latestPattern := strings.Replace(r.URL.Path, "/docs/", latestPath, 1)
	http.Redirect(w, r, latestPattern, http.StatusTemporaryRedirect)
	})

But make run/site uses hugo server command, which creates the server internally to check the behavior and doesn't use our server. 😇

So I tried to execute hugo to build the files and go run main.go in the docs dir, then it worked well.
(I added the small fix to check the build result, change from "/public" to "./public" at this line)
