Crypt-LE VS acme-companion

Normally you can use the same .csr forever if the domain is the same - I normally use LE64 to generate let's encrypt certificates (which can do wildcards also), but if you're purchasing a certificate rather than generating a free one, and you want to generate it right in IIS, you can follow a guide like this. If you generate a wildcard cert like *.domain.com, you can use it for all your subdomains but NOT generally for domain.com itself (depending on your application). You can use the same certificate for all applications provided they support whatever format the certificate is in; mostly these will be in PEM-style anymore so you have the whole cert chain in one file.

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:

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
