acme-companion VS caddy-docker

My hunch is that because I decided to include the acme-companion image in this nginx setup, that maybe it has something to do with the SSL certs? The only other thing I could think of is that I had to combine the networks in order for nginx-proxy and Sonarr both to be able to see my transmission instance via:

Probably want acme with nginx https://github.com/nginx-proxy/acme-companion

setting up letsencrypt with nginx-proxy and acme-companion

I'm experiencing a weird situation, and am not sure how to go about finding a solution. I am running the nginx-proxy container (https://github.com/nginx-proxy/nginx-proxy) together with the acme-companion container (https://github.com/nginx-proxy/acme-companion) to provide https connections to all my different applications under different subdomains on the same host (currently, for testing purposes: only two other nginx containers with a plain html page).

We use the nginx-proxy docker image with its acme-companion to have an auto configuring SSL reverse proxy, so it's really easy to deploy images (we do it based on a merge PR into protected release branches).

Use a reverse proxy to handle TLS/SSL encryption. I find nginx-proxy with companion easy to use, just follow steps 1, 2, 3.

Where I'm running into issues is with the two stacks I have deployed - one is a wordpress stack which uses the wordpress image along with a db image (going by the docs here), and the other is the nginx-proxy and acme-companion (going by the docs here).

Just use nginx-proxy and the LetsEncrypt companion as reverse proxy to handle TLS/SSL in front of your web server.

You can simply use this proxy container which automatically generates nginx config based on envs set in your containers. There is also a companion container which takes care of your certs. https://github.com/nginx-proxy/nginx-proxy https://github.com/nginx-proxy/acme-companion

The official Caddy documentation of their Docker image: https://hub.docker.com/_/caddy

I use https://static-web-server.net/

Cross-platform, written in Rust, straightforward configuration, secure defaults, also has a hardened container image and a hardened NixOS module.

I wouldn't recommend Caddy. Their official docker image runs as root unnecessarily (and the reasoning suggests a lack of understanding) [1], and they don't provide a properly sandboxed systemd unit file [2].

There is also a short section about it on the Docker hub page under the "Adding custom Caddy modules" section: https://hub.docker.com/_/caddy

Caddy uses a number of volumes. Two point directly at files within our project, first our Caddyfile, then our public folder which Caddy will serve live files. The other two are virtual filesystems Docker will create as defined by the master volumes parameters. We can assume the caddy_config volume is where active configuration is stored as it is not discussed on the Caddy Docker Official Image page, so we're copying their parameter exactly, but the caddy_data volume needs some extra discussion. It is used to store a number of things including SSL certificates. By default Docker creates and destroys volumes upon startup and exit. As we want to persist our certificate across sessions we can take advantage of an external Docker volume. These virtual filesystems are created before starting the Docker session for the first time. This can ve done from the command line or more easily from within the Docker Desktop app. Simply choose "Volumes", click the "Create" button and specify caddy_data.

I've been able to create a network with no issues (that I know of yet) but when I try to create the volumes I run into trouble. This specific example is from Caddy2...

For a reverse proxy I would suggest Caddy. The configuration is super easy and it handles SSL for you out of the box using LetsEncrypt! There’s also an official docker image like PHP and MySQL here https://hub.docker.com/_/caddy

Their image is dead simple to use, the config is fine, and auto-https is baked in. You can use it as a sidecar, proxy for multiple images, or just as a base to add your app into, depending on the complexity of your existing config.
