Ok. So I am finally ready to jump into V2 but I have two questions related to plugins
What V1 plugins/modules are available for V2 (is there a list like on the v1 website)? In particular I need the route53 dns plugin.
I run caddy mostly on armv8 machines. At the V1 caddy web it would compile an executable with the plugins I chose for the architecture I chose and then I could download it. Looks like in V2 I have to compile it myself? I have a setup of go with modules for my dev x86 for doing basic compiles of go source but since I am not a go programmer I have no idea how to cross compile for armv8. I don’t really want to compile on my armv8 machines directly they are for production and also at least with kernal compiles, slow. What is going to be the easy way to create custom binaries (i.e. with plugins) for armv8?
There is no central registry yet. Like with v1: first I need to get the software released, and then I can spend time working on the website.
v2 doesn’t yet have full-fledged DNS provider support, since I need to do some major refactoring of a fork of an upstream project first. But if you don’t mind using a PR that someone made, you can at least use Route53 sooner than later with v2: https://github.com/caddyserver/tls.dns/pull/2
We have compiled binaries for various platforms at our Download link (expand the “Assets” link – I wish GitHub would make those more prominent but whatever).
Of course, these don’t have extra plugins installed.
Use xcaddy - you can cross-compile just like you would with the regular
GOOS=linux GOARCH=arm64 xcaddy build ...
Thx for info. I wrote a bash script to make this easier but it throws an error for that PR. Maybe I just don’t have the right module url?

Another issue is that if the build completes (i.e. I leave out the module for now) xcaddy tries to run the executable (why I asked for build) but it fails for some permission error (why?). Owner of folder is same as user who launched the script. . Not a big deal my script runs it for version afterwards anyway

^ I think that is a GitHub URL, not a Go module path. I have never done this for a fork before, so I don’t know much here.
As for the permission error, I have absolutely no clue…
Could you try:
that got me a bit further. some issue with path now. Maybe @danlsgiga who submitted the PR knows how to get this module incorporated correctly?

Oh, yeah, this is because it’s a fork… hmm… needs a
replace statement. I’m not sure xcaddy supports that yet… I suppose I need to implement something like:
Uh… for now - make your own fork of danlsgiga’s and replace the package name in it
Exactly! I had to build it with a
go mod edit -replace github.com/caddyserver/tls.dns=github.com/danlsgiga/tls.dns for it to work!
@danlsgiga Sorry as I mentioned I’m a go coder noob. Guess I’m gonna more explicit directions
In this case seems I can’t use
xcaddy (doesn’t support replace) but must compile from the source?
ok so I cloned caddy2 source
So then I run
mod edit -replace github.com/caddyserver/tls.dns=github.com/danlsgiga/tls.dns on the caddy 2 source right?
whoops another error
go mod: -replace=github.com/caddyserver/tls.dns=github.com/danlsgiga/tls.dns: unversioned new path must be local directory
I assume that
github.com/caddyserver/tls.dns is already a module that caddy2 source pulls? cause I have no idea how to add modules with
go build like
hmm… if I look at go.mod
github.com/caddyserver/tls.dns is not even listed` so maybe the error
Anyway noob confusion some steps appreciated.
I think the easiest solution is to make a fork of @danlsgiga’s repo, make a commit to change the
module github.com/caddyserver/tls.dns to
module github.com/<your-username>/tls.dns then use
github.com/<your-username>/tls.dns@<commit-hash> with xcaddy.
Not a permanent solution, but it should work for now.
ok that worked.
For others who might need more explicit directions
- In your github account fork https://github.com/danlsgiga/tls.dns
- Rather than pull down change/commit and push you can edit the file in place in your browser
- Edit the first line replacing caddyserver with your github username
- At the bottom set a commit message and save
- Go to repo main page and click on commits. Find your last commit and click on the copy the commit hash stamp.
- then with xcaddy use
--with github.com/<your-username>/tls.dns@<commit-hash> pasting in the commit-hash from step 5
I’m guessing this should work for anyone wanting to try a plugin/module that has yet to be merged into the caddy source.
now I guess my last question @danlsgiga
Is the route53 tls dns setup/directive changed from V1? or can I just refer to the V1 docs?
@dkebler, you can use the json config I’ve referenced here
