Configuration via the Caddyfile requires use of env variables, but
an upstream issue is currently blocking that:
https://github.com/go-acme/lego/issues/1054
Providers will need to be retrofitted upstream in order to support env
var configuration.
This allows individual directives to be ordered relative to others,
where order matters (for example HTTP handlers). Will primarily be
useful when developing new directives, so you don't have to modify the
Caddy source code. Can also be useful if you prefer that redir comes
before rewrite, for example. Note that these are global options. The
route directive can be used to give a specific order to a specific group
of HTTP handler directives.
This commit goes a long way toward making automated documentation of
Caddy config and Caddy modules possible. It's a broad, sweeping change,
but mostly internal. It allows us to automatically generate docs for all
Caddy modules (including future third-party ones) and make them viewable
on a web page; it also doubles as godoc comments.
As such, this commit makes significant progress in migrating the docs
from our temporary wiki page toward our new website which is still under
construction.
With this change, all host modules will use ctx.LoadModule() and pass in
both the struct pointer and the field name as a string. This allows the
reflect package to read the struct tag from that field so that it can
get the necessary information like the module namespace and the inline
key.
This has the nice side-effect of unifying the code and documentation. It
also simplifies module loading, and handles several variations on field
types for raw module fields (i.e. variations on json.RawMessage, such as
arrays and maps).
I also renamed ModuleInfo.Name -> ModuleInfo.ID, to make it clear that
the ID is the "full name" which includes both the module namespace and
the name. This clarity is helpful when describing module hierarchy.
As of this change, Caddy modules are no longer an experimental design.
I think the architecture is good enough to go forward.
* Always cleanup admin endpoint first
* Error out if no config has been set (#2833)
* Ignore explicitly missing admin config (#2833)
* Separate config loading from admin initialization (#2833)
* Add admin option to specify admin listener address (#2833)
* Use zap for reporting admin endpoint status
