Question: using the admin API alongside CDP?

[amosbastian]

I'm using Dokku to deploys my apps and using their Caddy proxy, which is caddy-docker-proxy. One of my projects is a SaaS where users can add a custom domain.

In the past when I wasn't using caddy-docker-proxy and just had Caddy running in a container, I'd use the admin API to add entries, and this was working fine.

So, my question is basically if I can do the same while using caddy-docker-proxy? I'm assuming it won't be recommended to mix using labels and the admin API, and if so, what would you recommend instead?

But no, you should not try to modify the config using the API if you're using CDP, because next time CDP makes a change it will wipe away your own change. You should do it via CDP's labels, or via a base Caddyfile (see env var options in the README).

I need to modify the Caddyfile to add new entries, so I don't see how using a base Caddyfile is a solution here? I guess I should just get rid of CDP since it seems like it doesn't support my use case

It depends what you mean by "entries". What config are you trying to add exactly?

As explained above, basically users can add a custom domain, so then I'll call the admin API and it will add a route like this

{
  "admin": { "listen": ":2019" },
  "apps": {
    "http": {
      "servers": {
        "test": {
          "listen": [":443"],
          "routes": [
            {
              "handle": [
                {
                  "handler": "reverse_proxy",
                  "rewrite": { "uri": "/test{http.request.uri}" },
                  "upstreams": [{ "dial": "localhost:1234" }]
                }
              ],
              "match": [{ "host": ["example.com"] }],
              "terminal": true
            }
          ]
        },
        "local": {}
      }
    }
  }
}
