How correctly install ssl certificate using certbot in docker?

Question

I am trying to deploy Node.js/Express application with Docker, using Let's Encrypt SSL certificates for HTTPS.

When I run docker-compose up command all 3 services started but I notice such warning:

Saving debug log to /var/log/letsencrypt/letsencrypt.log
No certs found.

This warning happens when docker tried to execute RUN /scripts/certbot-auto -n certificates command in certbot/Dockerfile file.

Inside /var/log/letsencrypt/letsencrypt.log file I see this:

2019-08-21 10:27:50,354:DEBUG:certbot.main:certbot version: 0.37.1
2019-08-21 10:27:50,355:DEBUG:certbot.main:Arguments: ['-n']
2019-08-21 10:27:50,355:DEBUG:certbot.main:Discovered plugins: PluginsRegistry(PluginEntryPoint#apache,PluginEntryPoint#manual,PluginEntryPoint#nginx,Plugin$
2019-08-21 10:27:50,372:DEBUG:certbot.log:Root logging level set at 20
2019-08-21 10:27:50,372:INFO:certbot.log:Saving debug log to /var/log/letsencrypt/letsencrypt.log

Also in the logs of nginx container I notice such warning:

2019/08/21 10:28:37 [emerg] 1#1: cannot load certificate "/etc/letsencrypt/live/tols/fullchain.pem": BIO_new_file() failed (SSL: error:02001002:system library:fopen:No such file or directory:fopen('/etc/letsencrypt/live/tols/fullchain.pem','r') error:2006D080:BIO routines:BIO_new_file:no such file) 

QUESTION: As far as I understand, ssl certificate was not created. How fix this problem and correctly install certificate using certbot?

Just deploy docker container with this command to install letencrypt ssl certificates

docker run \
--name=letsencrypt \
--cap-add=NET_ADMIN \
-e PUID=1000 \
-e PGID=1000 \
-e TZ=Europe/London \
-e URL=your.domain.com \
-e VALIDATION=http \
-e EMAIL=****@gmail.com \
-e PROD=true \
-p 443:443 \
-p 80:80 \
-v /path/to/appdata/config:/config \
-d \
--restart unless-stopped \
linuxserver/letsencrypt

Now auto renew certificates with the script available in /app/le-renew.sh Install crontab to do this

0 0 1 * * sudo docker exec letsencrypt /app/le-renew.sh
