+	command.Flags().StringP("version", "v", "", "The version or leave blank to determine the latest available version")
+	command.Flags().String("path", "/usr/local/bin", "Installation path, where a caddy subfolder will be created")


It's not the usual pattern, but Caddy installs to /usr/bin/

Have a look at the faasd script to see what else may be missing, including adding users etc.

For adding users, we will need to detect the OS from /etc/os-release and reject the command if it's not debian or ubuntu.

In the future, if someone needs this for Alpine or Fedora, they can add a patch to run useradd with the correct syntax for their distro.

There are also some directories created and chmod is run.

alexellis

Good start, but there's more needed for a system install to match how Caddy is installed with faasd: https://github.com/openfaas/faasd/blob/master/hack/install.sh

The new changes look like what I was expecting.

Could you test this and see if Caddy starts up correctly on a new Linux VM you create somewhere?

If you need a sample Caddyfile, you can change the domains for the below:

faasd.example.com {
    reverse_proxy 127.0.0.1:8080
}

cmd/system/caddy.go

+		}
+
+		commands := strings.Join(shellCmds, "; ")
+		if err = exec.Command(commands).Run(); err != nil {


Could you try go-execute which is used elsewhere? It has a shell option if needed.

alexellis · 2024-05-29T15:58:49Z

cmd/system/caddy.go

+		// TODO: Add empty CaddyFile and if required FAAS_DOMAIN setup too
+
+		shellCmds := []string{
+			"$SUDO chown --recursive caddy:caddy /var/lib/caddy",


I think $SUDO could be removed, and arkade could be run as sudo arkade if needed.

cmd/system/caddy.go

+
+		caddyUser := "caddy"
+		if _, err = user.Lookup(caddyUser); errors.Is(err, user.UnknownUserError(caddyUser)) {
+			addUserCmd := fmt.Sprintf("$SUDO useradd --system --home %s --shell /bin/false %s", caddyHomeDir, caddyUser)


Try go-execute again which splits out cmd vs args

alexellis · 2024-05-29T16:01:17Z

@nitishkumar71 suggested using the "get" method from the tools code. I think it would be worth trying out as an experiment.

cmd/system/caddy.go

+			return err
+		}
+
+		if _, err = executeShellCmd(context.Background(), "systemctl", "start", "caddy"); err != nil {


Skip the start, and then you can also omit createCaddyConf

cmd/system/caddy.go

+			return fmt.Errorf("this app only supports Linux")
+		}
+
+		tools := get.MakeTools()


Does this change mean that "caddy" also appears via arkade get caddy?

In the case of things like Go or Node, we won't that because it won't do the right thing. We could have an additional flag or bool etc on each Tool to hide them from the arkade get command

Agree. will start working toward migrating system apps to use this new approach and enable apps which we want as system install only

alexellis · 2024-06-05T15:55:18Z

cmd/system/caddy.go

+
+		tools := get.MakeTools()
+		var tool *get.Tool
+		for _, t := range tools {


I like this approach. Could you create an issue to retrofit this into the existing system install apps?

Sure. I would try to progressively apply this approach in system install apps.

alexellis

Could you see the suggestions please?
