nginx-proxy VS caddy-docker-proxy

I have an express API that runs on EC2 and I am using nginx-proxy

If Traefik is not your thing Im happily using https://github.com/nginx-proxy/nginx-proxy and sslip.io for local docker compose development.

And then even plain nginx to proxy to non docker services...

(And ipv6 for really short urls. E.g. `example.com.--1.sslip.io` etc)

I wanted to share with you an exciting new tool that simplifies the process of interacting with the NGINX Proxy Manager API. It's a TypeScript tool that generates API requests based on environment variables within a Docker container. This tool is heavy influenced by the https://github.com/nginx-proxy/nginx-proxy but it works with npm.

I use an automatically configuring reverse proxy - there's several to choose from, but the nginx-docker image is really nice, and comes with another image to do automatic SSL with certbot (if you wanted to host things externally).

Docker runs on the 3B+ so you could use this [Github] or the one I have deployed here [NGINX Proxy Manager site] amongst others.

- and this

docker compose + wildcard dns + reverse proxy that covers all widecard subdomains + https://github.com/nginx-proxy/nginx-proxy (not to be confused with nginx itself) then setup a container for each app and set a subdomain for it, you can add ssl if you have a public domain or use self signed certs (but you need to distribute it to all machines and devices)

setting up letsencrypt with nginx-proxy and acme-companion

We use the nginx-proxy docker image. Auto-configuring reverse proxy with support for certbot. Never been easier - just put your domain and certbot details in your container env, and it does the rest.

I just use the nginx-proxy image, makes it all super easy, auto-configuring, and all domain/cert information is stored against the project rather than the proxy.

Caddy via Caddy Docker Proxy (network).

https://github.com/lucaslorentz/caddy-docker-proxy

It handles the routing to multiple dockerized projects on one server, by scanning docker compose files for labels and automatically setting up the required caddy configuration.

My go to is always this instead:

https://github.com/lucaslorentz/caddy-docker-proxy

Single label to a docker container and with correct DNS you’ll have an automatically managed certificate right away.

I have had a great experience with using this: https://github.com/lucaslorentz/caddy-docker-proxy

It combines caddy with docker-compose labels, making it super easy to spin up new projects that can immediately be exposed.

If you want a slightly heavier but more robust solution, caddy-docker-proxy[0] is a plugin that listens to the Docker socket and automatically updates the Caddy configuration based on Docker labels you add to containers.

I.e. it makes Caddy act a bit more like Traefik. Most of the time, you'll just add the label `caddy.reverse_proxy={{upstreams http 8080}}` to your containers and the plugin will regenerate Caddy's configuration whenever the container is modified.

I disagree, Caddy works great in Docker. See https://caddyserver.com/docs/running#docker-compose, and CDP is a project that autoconfigures Caddy from labels https://github.com/lucaslorentz/caddy-docker-proxy. Regarding plugins, it's super simple to write a Dockerfile to add plugins, we ship a builder image variant that can be used to compile in any plugins you want.

This way, Caddy will buffer the request and give 30 seconds for your new service to get online when you're deploying a new version.

Ideally, during deployment of a new version the new version should go live and healthy before caddy starts using it (and kills the old container). I've looked at https://github.com/Wowu/docker-rollout and https://github.com/lucaslorentz/caddy-docker-proxy but haven't had time to prioritize it yet.

Docker labels support is available via a plugin https://github.com/lucaslorentz/caddy-docker-proxy
