Minimal docker alpine based customizable http nginx redirect / proxy service
Configure redirect.conf with your redirections / proxy server directives.
Then, build and run the image with:
$ docker build -t redirects .
$ docker run --rm -d --network=host --name nginx redirects
Mounting the letsencrypt folder, https certificates can be used in redirect.conf.
Run the container with the mounted folder:
$ ./up-with-volumes
Manual docker run command
$ docker run --rm -d --network=host -v $PWD/letsencrypt:/etc/letsencrypt --name nginx redirects
Open a shell in the container:
$ docker exec -it nginx sh
and start certbot certificate generation:
# certbot certonly --nginx
Which names would you like to activate HTTPS for?

Cleaning up challenges
# exit
optional: pay attention to choose domains in pairs in order to generate domain-specific certificates in a proper folder with the domain name
Now configure redirects.conf to use ssl certificates just generated under letsencrypt/live folder.
Then rebuild the docker image to use the new redirects.conf file
$ docker build -t redirects .
and restart a new container
$ docker rm -f nginx
$ ./up-with-volumes
