Not able to install plugin dyndns

[reitoo]

Hi

I tried to install the caddy plugin dyndns with below command:

`docker build --build-arg \
    plugins=dyndns \
    github.com/abiosoft/caddy-docker.git`

(also tried with plugins=caddy-dyndns)

And got error plugin not found, here is the full log

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

  git checkout -b <new-branch-name>

Which plugin is dydns? I can only see https://caddyserver.com/docs/tls.dns.dyn. And in that case, you should use dyn as the plugin name.

I too stumbled on this while trying to use route53 plugin.

dyndns. Failed to find it. @abiosoft

Apparently the fault is from upstream and just been fixed https://github.com/mholt/caddy/pull/2521.

However, since the builder builds from release tags, it would not be available until the next Caddy release.
