only first domain works

[hanscees]

Hi,

I tried the init script with 6 domains. Only the first one works because the dummy cert is only created for the first domain.

The script does this:

`echo "### Creating dummy certificate for $domains ..."
path="/etc/letsencrypt/live/$domains"
mkdir -p "$data_path/conf/live/$domains"
docker-compose run --rm --entrypoint "
openssl req -x509 -nodes -newkey rsa:1024 -days 1
-keyout '$path/privkey.pem'
-out '$path/fullchain.pem'
-subj '/CN=localhost'" certbot
echo

`

but should include a for i in loop of some kind like the script does use later

domain_args="" for domain in "${domains[@]}"; do domain_args="$domain_args -d $domain" done

unless I am mistaken of course

[hanscees]

I use another docker volume:

certbot:
image: certbot/certbot
volumes: - certbot_conf:/etc/letsencrypt - certbot_www:/var/www/certbot

to make it work for my I adapted the script like so:

`
#!/bin/bash

if ! [ -x "$(command -v docker-compose)" ]; then
echo 'Error: docker-compose is not installed.' >&2
exit 1
fi

domains=(www.example.com www.example.net www.tieser.com )
rsa_key_size=4096
#data_path="./data/certbot"
data_path="/var/lib/docker/volumes/nginx_certbot_conf/_data"
data_path_container="/etc/letsencrypt" # the openssl looks in the comtainer
email="[email protected]" # Adding a valid address is strongly recommended
staging=1 # Set to 1 if you're testing your setup to avoid hitting request limits

if [ -d "$data_path" ]; then
read -p "Existing data found for $domains. Continue and replace existing certificate? (y/N) " decision
if [ "$decision" != "Y" ] && [ "$decision" != "y" ]; then
exit
fi
fi

if [ ! -e "$data_path/conf/options-ssl-nginx.conf" ] || [ ! -e "$data_path/conf/ssl-dhparams.pem" ]; then
echo "### Downloading recommended TLS parameters ..."
mkdir -p "$data_path/conf"
curl -s https://raw.githubusercontent.com/certbot/certbot/master/certbot-nginx/certbot_nginx/_internal/tls_configs/options-ssl-nginx.conf > "$data_path/conf/options-ssl-nginx.conf"
curl -s https://raw.githubusercontent.com/certbot/certbot/master/certbot/certbot/ssl-dhparams.pem > "$data_path/conf/ssl-dhparams.pem"
echo
fi

echo "### Creating dummy certificate for $domains ..."
for domain in "${domains[@]}"; do
#path="/etc/letsencrypt/live/$domain"
path="$data_path/conf/live/$domain"
path_container="$data_path_container/live/$domain"
mkdir -p "$data_path/live/$domain"
docker-compose run --rm --entrypoint "
openssl req -x509 -nodes -newkey rsa:1024 -days 1
-keyout '$path_container/privkey.pem'
-out '$path_container/fullchain.pem'
-subj '/CN=localhost'" certbot
done
echo

`
Difficult because your script runs openssl in the container, so there is a difference between the datapad on the docker host and in the container.

Possible duplicate of #65

[fredo994]

I've also walked right into this problem. I wanted to have two separate certificates for two different websites, but one reverse proxy. I've refactored this init-letsencrypt.sh script to support different domains.

domains variable now acts as "array of arrays" where sub-arrays are encoded as as string (values separated by whitespace).

I've tested this with my workflow and it worked.
Hope, somebody else will find this useful.

[sugenk]

another small fix for init-letsencrypt.sh

[oem2]

@fredo994 This solved my problem. Thanks so much

[EdwardDiehl]

@fredo994 thanks for sharing your init-letsencrypt.sh

this does not work correctly

("example.com www.example.com" "api.example.com www.api.example.com")

without quotes, it works correctly

(example.com www.example.com api.example.com www.api.example.com)

[Ibsardar]

@EdwardDiehl @fredo994

Thank you for this awesome script.
With some tweaks, I believe I got this to work correctly:

("example.com www.example.com" "api.example.com www.api.example.com")

I also incorporated the following (useful if you use a DNS supported by certbot) based on if you provide a non-empty string to dns_cred_path:

#88 (comment)

Make sure to replace all instances of nginx_service with the name of your nginx_service, certbot_service with the name of your certbot service, and dnsprovider with the name of your DNS provider (if any).

FYI dnsprovider usually is their full name, uncapitilized, without any spaces. So for Digital Ocean, you get "digitalocean".

Boom:

On another note, I have made my own boilerplate (based on this repo) that worked much better for me than this repo, mainly because I needed to incorporate digitalocean DNS stuff, additional Dockerfile steps, and custom Dockerfile entrypoint shell scripts.
