Caddy on Raspberry B - Build with plugin WOL

Help
1

1. Caddy version: v2.6.2

2. How I installed, and run Caddy:

I installed with the help of francislavoie with a downloaded file for my old Raspberry:
sudo dpkg -i caddy_2.6.2_linux_armv6.deb

I did nothing except for “caddy run” and test if 192.168.1.2:80 shows that caddy is working before trying to build with the plugin.

a. System environment:

Linux raspberry 5.15.84+ on Model B Revision 2.0 with ARMv6 CPU

3. The problem I’m having:

I am trying to use xaddy to include a WOL Plugin which I need for my intended usecase of caddy.
I tried with

xcaddy build v2.6.2 \
    --with github.com/dulli/caddy-wol

but I think my Raspberry is too old/slow to get it done or I am doing something the wrong way. It downloads lots of files and freezes at some point (see #4). I interrupted with Ctrl+C after 30 minutes sitting at the last “error”.

4. Error messages and/or full log output:

5. What I already tried:

I was thinking of trying to compile the new .deb on another machine, but lack the knowledge (and machine). I am a bit confused as to why so many things get downloaded. The go folder (/home/Breece/go) on my raspi is growing rapidly (now at 1,x GB)
Is there a way to use WOL in caddy without this plugin? Its integration looked quite elegant, but I am open to ideas.

6. Links to relevant resources:

That’s certainly possible. Those devices weren’t made to compile large projects.

What you can do is cross-compile, i.e. compile a build on a different machine which is more powerful. All you need to do is specify the GOOS and GOARCH environment variables to xcaddy build and it will build for that combination. So in your case, GOOS=linux GOARCH=armv6.

This works because Caddy is a pure-Go project, and has no external dependencies after being compiled (i.e. no dependence on C libraries and such which are platform dependent). The vast majority of Caddy plugins are also pure-Go as well.

Yeah, Caddy v2.6.2 can’t build on Go 1.20. You’ll need to downgrade to Go 1.19 for the time being.

We’re about to release v2.6.3 in the coming days which will support Go 1.20 though.

You won’t need to make another .deb. You can use the dpkg-divert and update-alternatives instructions to just swap out the binary with your custom one. That’s the purpose of those steps. Now that you have something functional, you can follow those steps.

Thank you very much. I will wait for 2.6.3 and will try that cross compile. Will “updating” / “installing” the Deb file delete all settings, or keep them? I will have to build future updates, because of my armv6 plattform, won’t I? “Just” installing over the older version seems easier to me.

4

Installing new versions of the deb will only replace non-config support files, like the systemd unit, the default index.html welcome page, etc. Your Caddyfile is left untouched. Those support files change rarely, only if changes in Caddy itself call for it.

If you divert because you need to use a custom build for plugins, then installing the new deb doesn’t update Caddy itself because you “took control” of the Caddy binary.

Thank you again. Just to clarify:

If you divert because you need to use a custom build for plugins, then installing the new deb doesn’t update Caddy itself because you “took control” of the Caddy binary.

Does the following work:
I build a custom build with plug-ins and install it. An update for caddy geht’s published. I build the update with plug-ins and install.

Or do I have to do:
I build a custom build with plug-ins and install it. An update for caddy geht’s published. I build the update with plug-ins and divert.

6

You only need to do the divert steps once. After that, to update the binary, you replace /usr/bin/caddy.custom instead.

7

Thank you again (and again).
So I will wait for 2.6.3 just to start with the newer version. I will install it then build my custom binary with plugins, place it in the folder I will begin executing the whole divert part (as described in the documentation). So far so good?

For future updates, what do I replace in /usr/bin/caddy.custom (and where do I get what is needed to be replaced)?
I am, you never would have guessed, a bit new to this, so please forgive me for asking (most likely) obvious questions…

8

That’s the actual Caddy program itself. When you use xcaddy build, it produces a new program in the current directory named caddy (by default; you can use --output to change it). You can move that to /usr/bin/caddy.custom to replace your previous build.

I tried to build again with 2.6.3 (on the raspberry and on a VM with go v1.20 and 1.19.5) and got a different error:

Bah. I’m seeing the same error. I’m confused. It seems to be a bug in Go itself:

We’re looking into it :frowning:

Thank you. I went back and tried go 1.20/1.19.5/1.18 and 1.17.1
Except for 17.1 it’s always the same error, on 17.1 it’s a different one though. Other plug-ins work just fine, that’s why I created an issue at the WOL Plug-in. Maybe the dev has an idea.

On a side note: I thought I could do a workaround by using the exec plugin “exec wakeonlan Macadress” in “handle_errors”. Would that, or something similar work?

12

Caddy v2.6.3 (and a few previous versions) will only build on Go 1.18 and later.

Caddy v2.6.2 could not build on Go 1.20 because of our dependency on quic-go which specifically has to add support for newer versions incrementally for complicated technical reasons.

This is definitely a bug with Go, but it might be resolved by the WOL plugin updating its version of Caddy in its go.mod. That should absolutely not be necessary though.

I have no idea. You’ll need to try it out. I’ve never played with wakeonlan stuff.

13

So I could try to build an older version of caddy with an older version of go. I fiddled around with exec but could not get that to work. Version 1.7.1 seems to work, how far back do I have to go with caddy?

Reading trough that Go issue does not leave me hopeful for a “quick fix”, that’s why I am trying different routes. Unfortunately WOL is kinda a “must have” for me (which is neither your problem nor of your concern :sweat_smile:). Other than this issue I am really impressed with how easy caddy is to setup, especially with let’s encrypt.

Well, I think I have a workaround for you:

xcaddy build --with github.com/dulli/caddy-wol=github.com/francislavoie/caddy-wol@c115db6e

Edit: aaaand it’s fixed in panic: internal error on xcaddy build · Issue #1 · dulli/caddy-wol · GitHub so my workaround above shouldn’t be necessary anymore.

You and the author of the plug in were so quick, I could not (meaning did not have to) use your workaround (well technically I did because dully used it). Thank you very much for your patience and help.
It’s not much, but I will donate to the project/team.
